If the earth were microscopic and the sun was the size of a period at the end of a sentence, it would be one inch to the sun, the nearest star would be 4.3 miles away, but the nearest galaxy would be 2,500,000 miles away!

I just sat here and tried to visualize this best I could. And I could not. It's too insane to try. I never thought about it like that thank you.

[@beringstraitrailway]

Let's see...if one light year on this scale equals one mile, and one light year in reality is 5.88 trillion miles...then one thousand feet is slightly more than one trillion miles, 0.6 is greater than .588, so slightly more in this cases means about 10% more, so one foot is about 1.1 billion miles, about 11 and a half AU so the Earth to Sun distance would only a fraction of a 16th of an inch bigger than one inch. The OP appears to be right on. The Sun diameter is just a little less ths less than 1% of an AU so depending on the size the period at the end of the sentence, but in most cases the Sun would be smaller than a period at the end of a sentence. Wow!

[@DenverStarkey]

no one is talking about going to other galaxies. hell few sci-fi books/shows ever talked about going to other galaxies. also your rough math is off a little , more inches go into a mile than Au's go into a light year. an au being the distance between the sun and the earth. there are 63,240 Au's in a single light year while there are 63,360 inches in a mile. but i guess you are close enough for just popping off on a youtube board. fun fact in star trek warp 9.99 is 7,912 x the speed of light. while a flat warp 9 is only 830 times the speed of light. mean while warp 2 is only 8 times the speed of light , warp 3 is 27 times the speed of light. and in reality they are all nothign burgers .. because were we to make warp work , the ship itself would not actually be moving. jsut space around it would be contracting and expanding .

[@nateg08]

Supersonic flight and relativistic speed space travel aren't remotely comparable. One requires a little ingenuity, the other requires near infinite energy and engineering feats like a forcefield (which is nonsense) to protect from enormous radiation and debris. Even if they could harness the power of entire stars it wouldn't be enough energy. Warp drives and worm holes are fantastical nonsense too. Again even if they could get the maths to work it would require unrealistic amounts of energy.

[@samr.england613]

@8 You're right. As you know, people commonly make the kind of silly analogies like the one you're responding to here. According to the late physicist Freeman Dyson (the Dyson sphere guy), in order to warp space like Captain Kirk and company, it would take the energy of the entire Milky Way Galaxy to achieve such a thing. That's not just all the radiant energy in the Galaxy, but all the POTENTIAL energy, including every frickin' atom.

[@johnjones928]

And yet it took about 50 years after the first flight to understand that there are severe physical limits to how fast we can fly in earth's atmosphere, and how the effort expended rises as the returns for those efforts plummet. I mean look at travel on water, we're been doing that for centuries yet the fasted managed so far was just over 300 MPH, in fact anything over 50 is wasteful. But since there's an alternative called air travel there's no real pressing need to go any faster on water commercially.

Certain theories in physics suggest that the universe has more spacial dimensions that we currently have access to. If we learn how to access additional dimensions, it becomes trivial to connect two spacial points of a lower dimension. Imagine an ant walking along a string. It's basically a one dimensional world, forwards or backwards along the string. But a 3 dimensional creature, like us, can easily loop the string in any way we want, allowing the ant to "teleport" from any point on the string to any other point we choose with just a few short ant steps. And this works regardless of the length of the string. It isn't very hard for us to imagine how a very intelligent ant species could figure that out somehow and come up with a way of forcing an otherwise straight string to bend and loop across itself... so is it so hard to imagine that we could figure out a 4th or 5th dimensional solution for our 3 dimensional situation too? BTW: The video's entire argument is based on Einsteinian physics, which, like Newtonian physics, is known to be a very good guess and very useful for a lot of applications, but not 100% correct.

I'm as much a technological optimist as anyone, but as a trained economist, I fully understand the challenges posed by resource constraints and the difficulties of achieving "time consistency" in collective action requiring VERY long-term thinking AND resource commitments. I don't think these are insurmountable, just that we can't be naive about how to get from current point in space-time "A" to a hypothetically feasible future point "B". I'd even add to one of the skeptical points raised in the video. Trying to settle an already living world with its own complex, long-established biome is just as likely (and perhaps much more likely) to kill us and any earth-born biome we have to take with us to survive the trip than it is to suffer a total collapse in the wake of our invasion. We'd bring so little actual biomass (and such limited genetic variation) in comparison to the mass and genetic variation of what was already on the planet that we'd be something akin to a low-level infection of a sort that a complex living planet-spanning biome would already have seen many times before over its long natural history.

Been saying this for years. Humans will never travel the speed of light. Without that, the vast distances would make it an impossible journey. It would likely take the enormous resources of a combined planet working together to fund and develop such a mission. We know that is not going to happen. The video touched on some of the issues with long-term travel, namely cosmic radiation and forced isolation. But there are more issues. The "crew" you would select would know they are embarking on a journey never to return. The destination could prove inhospitable (they said that). Because it would take multiple generations, your crew would have to be selected from a genetically diverse group of people, otherwise future generations could suffer from birth defects associated with inbreeding. This means forced "pairing" based on necessity and not considering things like emotional or mental compatibility (love not a factor). The crew would have to be screened for genetics, but also filtered against bringing onto the ship any viruses or any other health threat to their survival. Any localized "pandemic" could wipe out the inhabitants. Ill crew would have to have medical treatments or be quarantined or ejected altogether. The crew screening would also have to include psychological as well as physiological examinations. Only the strongest in both could be considered. The initial crew would need to be able to withstand isolation to the ship for the remainder of their lives, never to walk freely outside the confines of the ship, witness a non-virtual scenic view, sunrise, or walk on a beach. Subsequent generation "might" have an advantage in that area as never having experienced such things, may not have reason to miss it. Also there is inter-human conflict to consider. Their would need to be an unbreachable established command structure to avoid any possible command authority or conflict issue. Any "turf" battles could lead to "war" followed by extinction. They would have to have a renewable bio system capable of producing sustaining oxygen, water and food and removal of waste. The biosphere can never experience any disruption of output or annihilation would result. I think the radiation issue would be the greatest one. They could not design a ship with sufficient shielding against radiation or the mass would be too great to ever leave the gravitational field of Earth (reach escape velocity). The radiation dosage accumulation over time would cause damage to cells and genetic mutations and cancers. It could speed evolution to the point if there were any survivors to "arrive" at all, they might no longer even be truly representative of the human species. Rather than that, I think it would just kill them outright. We aren't going anywhere.

Science couldn't prove how a twin rotor helicopter stays in the air, yet it does. Science can't explain why the human eye exists. It's too complex for evolution. Yet we all have them anyway. We all KNOW something that isn't true yet it exists anyway. We can't _prove_ everything, but that doesn't mean we'll stop trying. Logically, trying to create an environment we can survive in on another planet is a waste of time until a suitable propulsion system is invented to get us there. That's putting the chicken before the egg. We may never get out of our own solar system by traditional means, physical propulsion, but that doesn't mean someone won't eventually figure out how to fold space, utilize worm holes or invent a transporter like in Star Trek.

It was about materials, construction, and power. The actual physics was never the issue. Here we have the problem that the physics of the situation IS the issue. The distances involved make it a virtual impossibility and gives no benefit to the people who'd be paying for the thing. Also, as I pointed out, there's no way to test the equipment to be satisfactorily assured the journey could be successful. Something is bound to go wrong (e.g Apollo 13) and there's no way mission control could help even once you get too far out in our own solar system.

Also, what about all those countless generations in between that have never seen Earth and will never see the destination. All they do are slaving away, keeping the machine going for no benefit to themselves. And finally, unless the generation ship i very very very big... how do you prevent inbreeding in such a small population?

Some scientists believe interstellar travel, venturing beyond our solar system, is impractical with current technology due to the immense distances involved. Here's a breakdown of the challenges: * Vast Distances: Stars are incredibly far apart. Even the nearest star system, Proxima Centauri, is over 4 light-years away. Traveling at our current speeds would take millennia to reach even the closest stars. * Speed Limitations: Our current spacecraft are nowhere near fast enough for interstellar travel. Reaching even a small fraction of the speed of light would require significant technological advancements in propulsion systems. * Challenges of Interstellar Travel: Interstellar space presents a harsh environment with radiation and micrometeoroids posing risks to spacecraft and crew. Developing technologies for long-term life support and radiation shielding for journeys lasting years or decades is another hurdle. These scientists don't necessarily say interstellar travel is absolutely impossible, but rather infeasible with our current capabilities. Breakthroughs in propulsion technology, materials science, and life support systems could revolutionize interstellar travel in the future.

The same way one accelerates to lightspeed. Apply thrust. Just in the opposite direction. Just flip the ship 180 degrees and turn your thrusters on again: voila: you're decelerating.

A lot of this stuff seems to imply that the knowledge we have right now is as much as there is to know, when technologies that are just over the horizon could open up the entire universe (or even other universes) to us. Rather than just assume the rest of the universe is beyond our reach forever, I would counter with, the scientific knowledge and technology we have today does not allow us to leave the solar system, at least in the near future. But, by no means does that mean we will never have a solution a few decades, centuries, or millennia from now. All of our most advanced technological, scientific, and mathematical knowledge has only come to be over the past few hundred years.

"We assert that light is as fast as things get, and it certainly is" Bud, we measured the speed of light and we measured the electric vacuum permittivity and the magnetic permitivity ( the speed of light depends on both), they are universal constants and if any of them were different, the universe would look very different from how it is. And we have seen galaxies in the universe like ours.

To calculate the travel time to Alpha Centauri under constant 1g acceleration for the first half of the journey and 1g deceleration for the second half, both for the crew on board and an observer on Earth, we use the theory of special relativity, as the speeds involved approach the speed of light. Alpha Centauri is approximately 4.367 light-years away. We assume the spacecraft accelerates at 1g (9.81 m/s²) until the halfway point, then decelerates at 1g until it stops at Alpha Centauri. ### Time Experienced by the Crew 1. **Acceleration Phase**: The time experienced onboard during the acceleration phase can be calculated using the relativistic rocket equation. The equation for the time experienced onboard is given by: \[ t' = \frac{c}{a} \sinh^{-1}\left(\frac{a d}{c^2} ight) \] Where \( t' \) is the proper time experienced onboard, \( c \) is the speed of light, \( a \) is the acceleration, and \( d \) is half the distance to Alpha Centauri. 2. **Deceleration Phase**: The time experienced onboard is the same for both the acceleration and deceleration phases due to symmetry. 3. **Total Crew Time**: The total time experienced by the crew is twice the time of one phase. ### Time Seen from Earth 1. **Acceleration Phase**: The Earth observer time can be calculated using: \[ t = \frac{c}{a} \left( \sqrt{\left(\frac{a d}{c} ight)^2 + 1} - 1 ight) \] 2. **Deceleration Phase**: The time is the same for both phases from Earth's perspective. 3. **Total Earth Time**: The total time as seen from Earth is twice the time of one phase. Let's calculate these times. The calculated travel times are as follows: 1. **Time Experienced by the Crew for One Phase (Acceleration or Deceleration)**: Approximately 47,432,800 seconds, or about 1.5 years. 2. **Total Time Experienced by the Crew for the Entire Journey (Acceleration and Deceleration)**: Approximately 94,865,601 seconds, or about 3 years. 3. **Time Seen from Earth for One Phase (Acceleration or Deceleration)**: Approximately 20,658,093,469,440,110 seconds, or about 654,000 years. 4. **Total Time Seen from Earth for the Entire Journey (Acceleration and Deceleration)**: Approximately 41,316,186,938,880,220 seconds, or about 1,308,000 years. These calculations illustrate the significant effects of time dilation as predicted by the theory of special relativity at high speeds. The crew experiences a much shorter journey time compared to the time observed from Earth.

ELI5 : Imagine you're in a super fast spaceship going to a star that's really, really far away, like Alpha Centauri. This spaceship can go almost as fast as light! For the People in the Spaceship: If you were in the spaceship, you'd feel like the trip didn't take very long. First, you speed up (like when you're in a car and it goes faster and faster), and then, halfway there, you start slowing down until you stop at the star. This speeding up and slowing down feels like it takes about 1.5 years for each half of the trip, so the whole trip feels like it's about 3 years long for you. For People Back on Earth: Now, if someone was watching you from Earth with a super powerful telescope, it would look really different to them. For them, your trip to the star and back seems to take a really, really long time, like over a million years! This difference happens because of something called "time dilation." It's like a weird rule of the universe that says when you go super fast (close to the speed of light), time goes slower for you compared to people who are not moving as fast. So, in your super fast spaceship, time is moving slower for you than for your friends back on Earth.

The way you begin with all the 'climate change' fear-mongering just spells out the agenda, 'don't spend money on trying to explore space, give all your money to the globalist mega-corporations and their government bureaucrat lackey's so they can pretend to 'save the planet' while creating a global police state to serve themselves.

Assuming time dilation occurs, the trip to anywhere at almost the speed of light would *not* be instantaneous to the crew. Time would progress normally for the crew, and they would take a little longer than actual light to get there (from their pov). From Their starting point, any observers would see them vanish into the distance as a short beam of light would - ie. they would essentially appear to disappear like when you turn a flashlight off.

The existence of complex evolving life alone, shows that there is a strange something behind the secrets of the universe, and that life itself was “written” into its coding. I don’t tend to believe in a god but I do think life is supposed to be playing a part in the universe some how. Technology, especially looking at humanity’s tech tree, also gives me a feeling of we were supposed to discover these things. I have no doubts we’ll find what it is we need to be among the stars, to find our cosmic kin. The universe wants us to do something, i just don’t know exactly what.

[@KrystofDreamJourney]

Yeah… God does exist, and is responsible for creating everything that we can observe and feel. The part that is missing is our inability to understand and define IT. Religions etc. that’s oversimplified attempt to understand and define God, but I think we may never know the absolute extent of the truth. I.E : what was before the Big Bang ? Why did the Universe become, and what exactly is the Universe ? Is it only what we can observe and detect ? But I am glad that we’re digging deeper into it, at least some of the most evolved and educated humans do… Interstellar travel in atom-based matter ?(including our biological existence) Well… it’s certainly good for the sci-fi movies 😊 It looks like in our abstract intelligence, that we as humans possess, the Universe realizes it’s own existence, and we just “hook up” via the invisible thread into the consciousness, which is a property of the universe. You are right : consciousness is inevitable, intelligence is inevitable. It’s coded into the fabric of everything. The Universe is self-discovering and defining itself via our intelligence. These things are deeper than I can understand, but (as an artist/musician) I can “feel” them…

Sense at last! I have been waiting patiently for a video like this. Thank you so much! I was starting to think I was going mad. The minute I mention we stuck like glue here. I am an artist not an astrophysicist, and yet everything I have seen, watched read or learned points to the logical understanding that we have way too little knowledge and technology to accomplish intergalactic travel, by far. Like very very very very far. Movies and the Apollo narratives created a buzz. But even those examples cannot hide obvious truths. And the way I get verbally attacked by believers in our space faring abilities in the future shows that there is an enormous emotional attachment to the idea we will be able to visit other planets or galaxies. I sincerely and respectfully even doubt Apollo successes. Mainly because nobody has managed the same achievement for over half a century. (insert raised eyebrow). Thank you again. Keep going.

I think we will colonize the Solar System, but that's not the answer either. We need to take better care of Mother Earth. Global population is plateauing, and that should help. Our best hope for traveling to the stars is for some of us to merge with the coming superintelligence which is the next step in our evolution. Maybe that is what will provide AGI with consciousness. And as you pointed out, an AI can take as long as it needs to explore the cosmos. A billion years is nothin to it.

No idea on the propulsion system, but as far as the huge ship that never breaks down goes, the trick is not to start with a ship. Pick yourself a nice, solid asteroid, mine it out into all the compartments you need to feed and house a stable, genetically viable population, and send it on its way. Plenty more available resources to mine and make into any spare parts or upgrades you need. As an added bonus, it's even easier to slow down because it'll have less mass when it gets there.

If the ecological scenario at the beginning of this video became true, there would be a world-wide collapse of civilisation. In such a case, no one would be capable of building a starship, even if they wanted to. More likely, our descendants would not even have the concept of interstellar travel. If we were ever to do it, I regard it as an essential pre-condition to achieve a stable, harmonious and prosperous world-state. There would have to be some improbable social and political developments. We can't handle even twentieth century technology - some of the technological developments required would be more likely to destroy civilisation before there was a chance to safely implement them in interstellar travel. Furthermore, there is the fallacious assumption that world leaders would make rational, logical decisions - which one is assuming they would make if interstellar travel is to occur. The fact is they don't.

[@raminagrobis6112]

It's amazing how people here who seem to trust man's infinite ingenuity to surmount insurmountable obstacles appear to have the faintest grasp of the physics of relativistic speeds. They use "warp drive" liberally as though it were a magical solution without even realizing what it entails. Physics is full of mathematical "possibilities" that are not grounded in any sort of reality. Just because solving an equation entails both positive and negative values doesn't mean that both signs have physical relevance. A "warp drive" is entirely dependent on the existence of something which has never been detected, found or produced anywhere in our universe: negative energy. Warp drive cultists seem to ignore the very basic question as to whether negative energy has any physical reality. Saying that this is analogous to mankind's perception of our ability to master flying centuries ago is simplistic to say the least. Da Vinci was able to propose "flying machines" that didn't make sense because he hadn't discovered the concepts of thrust, lift and drag, which were all within his grasp had he spent enough time on the engineering of his "flying machines". On the other hand, no amount of engineering refinements will lead mankind to master negative energy until someone provides any solid evidence that this concept exists outside the mathematics of an equation. Take the so-called "arrow of time". Countless equations where time is involved ignore the inevitable implications of thermodynamics which precludes that processes can occur in both directions according to time. That's because entropy considerations are generally ignored when handling physical equations involving time. The actual "feasibility" or reality of equations in physics is restricted by the laws of thermodynamics, which have never been disproved or for which no exception has ever been found. I, too, enjoy sci-fi. 'Stargate' was exciting notwithstanding the fact that wormholes, just like 'Star Trek''s warp drives, rely on something that has never been shown to exist in our physical reality (or reality, period!): negative energy. This whole discussion in fact, can be reduced to a few major constraints: 1) The impact of solid particles in the interstellar vacuum severely limits the speeds which would be safe for traveling 2) There is no protection whatsoever, even theoretically, against cosmic rays for the human body . The duration of interstellar voyages would become a preeminent limitation to our ability to withstand them. 3) As well explained in the video, as speeds approach the speed of light, the kinetic energy required to approach that speed increases exponentially. The point where any gain in increasing speed is neither realistic nor physically feasible from the start is rapidly attained. Thus sets nearly absolute limits to speeds real vehicles can reach for escaping our solar system. These 3 aspects impose severe limitations to interstellar travel. And those don't even take into consideration the numerous psychological, physiological and pathological issues that are so well detailed in this video. Some commentators have watched too much Star Trek or Stargate for their own good 😅.

[@Amaranthine1000]

Interesting points except that humans are in fact already traveling through space on a giant ship. It is the size of a planet but you are traveling through space just the same. You revolve around the sun and the sun itself is also moving as is the entire solar system and the galaxy. The Earth is traveling far faster than humans can manage at the moment and yet the particles aren't ripping the planet apart thanks to the natural defector shield. Humans also have their own shield against cosmic rays, it's called the magnetic ionosphere. Now can humans create a ship capable of doing the same thing the planet Earth does naturally? That remains to be seen, but the fact is, is that humans are already on a space craft that protects them from not only everything mentioned in the video but does so without needing the fuel humans currently rely on to move from one point to another. I know technically it is still not traveling out of the solar system, but the truth is traveling through interstellar space is already in motion, perhaps humans can learn how the Earth does this so efficiently and apply that knowledge to actual space craft, but that is something the engineers and scientists will have to devise.

[@gseeker_anew5479]

Assuming everything said here were correct, one thing fairly obvious was missed. Why, if we could get to the speed of light, would we assume we cannot go faster than the speed of light? Seeing as it is highly theoretical science to assume that the speed of light cannot be surpassed, then any assertion that we could not overcome that obstacle seems premature. Now I know what many will say... "but scientists have given us plenty of reasons why FTL isn't possible"... except they haven't, because we currently have no practical application to test the reasons given. This is why FTL travel still remains a goal. Assume for a moment that you are looking at a circle drawn on a piece of paper. Pick a point on the edge of that circle anywhere.... then draw a line across the circle at any angle. Now... imagine that circle were 3 dimensions... it suddenly becomes a sphere. This theoretical illustration of a wormhole may have been popularized in Hollywood, but it's still possible in theory to either create or find. Without knowing that we cannot, we have a duty to assume, and work with the assumption, that we can... This video was fun, but I'm an optimist, so forgive me if I don't buy the cynicism here.😂
