Interstellar Travel: Approaching Light Speed

Is interstellar travel doomed to remain in the realm of science fiction? Sticking to near future space propulsion only, how close can we get to the speed of light?
This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default.
For beating these speeds, this video explores what is possible in the near future only, so no antimatter, Alcubierre drives (warp), ramjets, etc... The EM drive is left out until it's proven with actual reproducible results in space.
Project Daedalus and the updated Project Icarus represent sound concepts for fusion spacecraft. IKAROS was the first successful demonstration of solar sail technology but hopefully the planetary society is not far behind with their LightSail cubsat (not covered in this video).
But what appears to have the most potential to reach the nearest star to our own, Proxima Centauri and it's newly discovered planet Proxima b is Breakthrough Starshot. Thousands of super lightweight laser sail nanocraft will be launched into space then the light beamer, a ground based laser array will propel these spacecraft to 20% light speed within minutes.

If it is, I would expect somewhat larger probes, or even manned "or aliened" ships, as they would be getting a *lot* of power from their star. Still, it's about 1400 light years away, so we're probably safe for a few more centuries...

[@mr.rhenium3167]

The only way to travel space in human time is to bend time itself

[@johnfrancisdoe1563]

Mr. Rhenium Simply traveling at a high percentage of c causes time dilatation so anything and anyone inside the ship experiences a shorter duration than those observing from the sidelines. This only becomes useful closer to c than the early designs in this video. Actually reaching or surpassing c would require finding a significant flaw in Einstein's theories of relativity, while reaching 99.9% of c only requires a lot of energy and the time to accelerate at a survivable G force.

[@j.jasonwentworth723]

That possibility has been discussed on Centauri Dreams www.centauri-dreams.com . A 1-kilogram probe moving at 0.3 c (30% of the speed of light) would, if it hit a planet, release as much energy as a 1-megaton nuclear weapon! The Starshot probes will weigh considerably less than 1 kilogram and will travel more slowly ("only" 0.2 c), but they will still pack the punch of a nuclear bomb. Stellar systems are by far mostly empty space, so the odds of a Starshot probe hitting a planet, moon, asteroid, or comet in the Alpha Centauri system (including in the very diffuse Oort comet clouds of its stars) are very tiny, but not zero...

[@nunyabisnass1141]

Jarvis Wilson-short there are a few problems with that claim. The most substantial being it doesn't make sense. The terms used to describe its operational capacity are incongruent. Saying that something can prepulse (maybe that was a typo) at X times the speed of light, is like saying that you can jump rope 24 times at 60mph. It doesn't say anything about velocity. Secondly, is the unlikelihood of a conspiracy to hide a miraculous technology from the world, especially coming out of China considering how globally competitive they are. Third is the this competitive nature that China has to be the first or the best at something, which has lead to numerous unverifiable scientific discoveries. Granted I'm only going off of what you said, and that I haven't seen the video you mentioned. But it sounds like there is already too much wrong with the claim to grant any reasonable credibility toward.

Violent2aShadow how much does it cost to build 100 power plants to power the lasers...

[@Wemdiculous]

Henry Jiang 10 billion divided by 17 trillion is way less than 7%. Less than .1%, but more importantly those lasers will continue to be useful long after this mission. It has been suggested that we should shoot lasers right below spacecraft simulating combustion by heating up the air with the lasers. If we dont have to carry the fuel we can reduce the weight of spacecraft and carry a lot more cargo for the same cost. If we do become an interplanetary species or even if we just need to reduce the cost of satelites or asteroid mining those lasers will eventually pay for themselves.

[@Wemdiculous]

You will not. Even if they launch those little probes it will take 20 years for them to get there and 5 years for the signal to come back. That's all you're going to see. Maybe.

[@gareththompson2708]

About 20 years until expected launch, another 20 years to reach their destination, plus about 4.4 years for the signal to return. About 45 years. If you are under 40 (maybe even if you are a little over 40) then you should be able to make it if you eat healthy and exercise (the average lifespan of an American male is just a little under 80 years, so if you are on the edge you may need to push a bit past the average, but average lifespans should increase a bit in that time too). I know I'm planning on sticking around for it.

[@Saugaverse]

Two things to keep in mind with interstellar space travel. First, no matter how fast you go, you also have to slow down once you arrive at your destination. Second, at very high speeds you run the risk of even small particles of dust destroying your spacecraft. So some sorta magnetic shield would have to be developed to deflect anything solid in the path of your spaceship.

[@robertspendlove7508]

Halfway there, you have to turn around and begin slowing down. Also, as you approach those speeds, doppler effect changes the colors of visible light and wavelengths of radio frequencies (yes, technically the same thing). You'll have more purples and higher freqency radio in front, and shifting to infra-red and lower frequency radio in the rear. Approaching the edge of light speed, you'd get a blackout in the rear.

[@inventorstar5816]

Magnetic field technology is the key to going lightspeed once you get into space two frozen magnets on a track and one in the middle cock it back with a spring like a gun

[@Saugaverse]

@@inventorstar5816 I agree with the magnetic field idea. Somehow they will have to generate a magnetic field around their spacecraft that is strong enough to deflect small rocks and even various types of radiation. Seems like a better option than heavy armored spacecraft walls.

[@shamsalveera]

@@Saugaverse that won't work if the spacecraft reach near speed of light since magnetic force acted on speed equals to speed of light..Before detection the obstacles the spacecraft will collide with them.

[@ate7714]

​@@shamsalveera yes plus this magnetic field or armor around the spacecraft would have to be capable of withstanding enormous forces since if it hits even a small rock that almost looks like dust weighting 0.001 kg the energy generated by the impact would be equal to a nuclear explosion

The worst thing about faster than light travel is, if you're going faster than light then you are literally time travelling.

People tend to think that relativity is a hindrance to exploring the galaxy because of c speed limit, not realizing that there is no limitation on how quickly a traveler can get to any particular destination in their own accelerating frame of reference, and in fact length contraction makes travel easier at relativistic speeds compared to how it would be in a cartesian universe. As you accelerate once you're at relativistic speeds length contraction increasingly decreases the distance you need to travel. 20% of c is already starting to show the effect. Just using the lorentz time dilation transformation on the example given of traveling at 20% c to Proxima C, 4 light years away, shows that while from earth it looks like it took you 20 years to get there, it really took you 18.8 years to get there. As you start edging beyond 20% c, that difference can become much bigger. If you were going 50% c, earth would see you get there in 10 years, but you'd really get there in 6.9 years.

[@farmerbold1144]

paki ... from your comment, you might be interested in my responses to some other related comments: Marlo Mamocod :) It would require infinite energy for a massive object or ship to reach the speed of light. However, a significant fraction of light speed 5 percent or 10 percent or even 15 to 20 percent is currently possible using lasers against a sail, or solar sails, or plasma (ion) drive engines of a craft. Warp drive engines are theoretical and promise much faster than light speed in the hopeful future and without the effects of Einstein's time-dilation as per his General Relativity Theory where time slows down proportionately to accelerating toward light speed. For each hour of the astronaut's time more time goes by for those left behind on earth. The astronaut could return in a year or two of his time experience and find his friends much older or dead of old age. Time-dilation would not apply traveling to other star systems using warp-drive technology in the hopeful future. Using warp drive means using a ring or torus to compress space in the direction of "travel" and expanding space in the opposite direction. The resulting effect is that the so called warp bubble alternately compresses and expands space to impart a forward traveling potentially faster that light travels in normal space-time (space + time). It can be very roughly compared to surfing a giant wave (instead of traveling in the water like a boat) toward the sandy beach full of pretty ladies in bikinis. So, within the warp field bubble, there is no speed relative to normal space-time outside the warp field bubble meaning Einstein's time-dilation would not apply. ============================================================ Farmer Bold Patrick Desch, You are close, sir. But Dark Matter represents the majority of mass in the universe ... "dark" because scientists do not know what it is even though it bends light through space-time as in the gravity-lens effect. Dark Matter accounts for about 25 percent of matter-energy, normal matter-energy accounts for almost 5 percent, and Dark Energy is about 70 percent of energy "dark" because scientist do not know what it is but it is causing the visible universe to expand increasingly fast rather than to slow down due to gravity in the universe of all stars, black holes, planets and moons etc. "Normal matter" has mass due to their protons and neutrons inside the nucleus of atoms with hydrogen atoms having only a proton (deuterium is hydrogen or a hydrogen isotope with one proton and a neutron in the nucleus orbited by a single electron. Deuterium is stable meaning not radioactive. And tritium is a hydrogen isotope with one proton and two neutrons and is not stable as it is radioactive. Any element like hydrogen or oxygen or iron or lead are defined by the number of protons that is the atomic number of the element or atom.). Recently, it was discovered that the "god particle" provided a Higgs-Boson (after the name's of two scientists) field that imparts mass (weight in the presence of gravity) to matter excluding photons or particles of light that is part of the electromagnetic spectrum (including radio waves, radar waves, infra-red or heat waves, visible light waves, ultraviolet waves that darken human skin, x-ray waves, gamma radiation waves, and cosmic radiation waves of infinitely increasing frequencies. As you correctly pointed out, photons have no mass and that is why photons are normally always moving in space-time (space + time) at almost 300,000 kilometers per second or 286,282.4 (?) miles per second relative to massive objects including people. ==================================================== ben l 9 months ago but could we send photos back from another star? ----- Farmer Bold Yes, photos and other data from other stars within a couple of decades or so. We will send a cluster of very small crafts using a number of lasers on earth to propel small sails for each craft for just a few minutes. Each sail with tiny craft would accelerate to around 20 (to 30???) percent light speed during a period of several minutes. They would not have to slow down or decelerate when approaching and passing the nearest binary star system that is 4.3 light years from earth. Photos and other data would be sent back to earth at about the speed of light of planets and moons of that distant star system. The cluster of many craft would insure more exposure and greater success and cover more objects in the other star system or systems. The craft will just continue traveling into deep interstellar space after the mission of sending photos and other data back to earth. ====================================================== Farmer Bold Jimiticus ... Wow! I use to wonder if such tech is possible. And if the sun then Dark Matter's gravity lens effect can be used for even better resolution of stars and exoplanets etc at much greater distances from earth. :)

[@farmerbold1144]

A LITTLE SCIENCE LESSON since I majored in science: "PLASMA" is the fourth (4th) state of matter ... 1. solid, 2. liquid, 3. gas, and 4. plasma. Plasma is extremely hot so as to ionize ATOMS into their negative and positive parts (electrons are negatively charged and protons are positively charged). An ATOM is the smallest part of any element of matter (stuff). Elements include hydrogen, helium, carbon, oxygen, iron, sulfur, sodium, chlorine, and uranium etc. But elements can combine or come together in a chemical reaction such as when oxygen and hydrogen combine to make water (H2O or H . O where . is the number 2) that is two hydrogen atoms and one oxygen atom making water). Sodium and chlorine chemically combine to make table salt (table salt is sodium chloride). ATOMS are neutral or without a charge or electric charge simply because atoms have the same number of neg. electrons orbiting the center or nucleus of an atom as the atom has positively charged protons located inside the nucleus or center of the atom. Note that a hydrogen atom has only one proton and only one electron ... but all other atoms have more protons and more electrons along with one or more NEUTRONS. Neutrons in the center of atoms have no charge and are therefore neutral in charge. But neutrons add to how heavy the atom is or add to the weight or atomic-weight of atoms. So, the simplest atom is the HYDROGEN ATOM with one proton in the middle and one electron going around or orbiting that proton. And a helium atom has two protons and two neutrons being orbited by two electrons. The atomic number of helium is two (because of two protons). And the atomic weight of helium is four (4) because of the two protons and two neutrons that weight almost the same (protons and neutrons). Electrons have a negligible or very light weight so typically don't need to be counted as adding to the weight of an atom. Now, when there is a TRANSFER of one or more neg. electrons then the atom that loses the electron(s) has more positively charged protons in the center or nucleus ... and the atom that receives one or more neg. electrons then has a neg. charge making the atoms now IONS. Ions are just atoms with a charge either positive or negative charge. An IONIC chemical reaction is the combination of OPPOSITELY CHARGED ions (that were atoms) and refers to the TRANSFER of neg. electrons from one atom to the other making them IONS with opposite charges that attract each other to make A COMPOUND such as table salt and water etc. In a PLASMA ROCKET, a hydrogen atom is ionized by heating it into plasma using microwaves (like in a microwave oven for food). The plasma is the hydrogen ion that is just a single proton. And the neg. electron is the other ion or charged particle. These ions come back together after the exhaust of the plasma rocket to form back into hydrogen with a neutral charge or no charge. The high speed of the exhaust of the rocket is very high in the energy of motion causing a reaction to push the rocket in the opposite direction or forward (as further into space). Plasma rockets that are actually ION ROCKETS, is an attractive method for drones or even people to travel to the stars such as to the nearest ones starting about 4.4 light years away. A light year is the distance light travels in a year that is about seven (7) times around the earth in a second. So, it would take about 46 years or more gradually speeding up to about 10 percent or a little faster the speed of light using ion drive engines or plasma rockets to get to the nearest star system. But about 96 years if people want to start slowing down half way there so as to maybe land on one one of the orbiting planets there. The earth people could complete the construction of a gigantic star ship (using small fusion bombs that are small nuclear bombs to power large ships with large amounts of materials into earth orbit. These materials would then be used in orbit to construct great star ships. This construction, if the world cooperates, might be done or completed over a period of maybe several decades (depending on how much billionaires are taxed etc.) like a Noah's arch star ship or several of them all in order to save humanity (several hundred people and plant/animal genetic material or embryos for each star ship) maybe from earth's collision with a giant asteroid so that people can be re-seeded to survive on a distant habitable planet. Several star ships are better than a single ship as per the saying "Don't put all your eggs into one basket." I'm too old to go, but I do not mind happily staying behind with billions of other people all in order to save enough of humanity or several thousand people including samples of all races and not just one or two dominant races of people ... you know what I mean.

Two of the most realistic interstellar space vessels Hollywood has made so far are the Venture Star (Avatar, 2009) and the Avalon (Passengers, 2016). The Venture Star is powered by anti-mater + nuclear fusion; while the Avalon is powered only by nuclear fusion. The Venture Star can travel at 130,000 mi/sec (209,537 km/sec); while the Avalon can travel at 93,000 mi/sec (150,000 km/sec). Both ships have living areas which generate gravity via centrifugal force, and both ships use frontal shields to protect from incoming debris.

Anyone thinking how can we beat light speed doesn't really get what the speed of light really is all about (hint - its not about light & not anything like a really fast version of the speed of sound barrier). The speed of light is in fact the maximum speed that any kind of signal or information can ripple through the spacetime fabric we all live in - it is the speed of reality - or causality. Lights travels unhindered at the maximum speed as it has no mass so that we we call it the same. It would be better to call it the speed of spacetime or speed of reality. If you go faster than the spacetime limit you end up time travelling with a whole lot of paradox questions to face - not just a big energy bill.

[@danmccarron0]

@ Not exactly. You MAY speed up the process - but once you hit fundamental limits it will only be refinements until you have breakthroughs in theoretical work. Look at the state of theoretical physics right now....getting so esoteric so that predictions made by a theorist are verified or refuted 100 years later. I'm not saying pouring 1000X more money into the effort won't help significantly, of course it will - but not like you think. That the hurdles are not funding, it's transitioning to new paradigms in scientific understanding and technology and if it doesn't develop independently from OTHER markets then the amount of effort is exponentially increased. Cumulatively worldwide, the commercial tech sector (for relevant things like like microprocessor development, AI, etc) likely exceeds the numbers you have listed. These developments are directly contributive to any space program and to humanity in general, but would never factor into a NASA budget because they don't reinvent the wheel when installing computing devices in their spacecraft. The better those beccome the better everything else becomes Another example: they discussed inertial confinement fusion here, which is outside of space program and related to commercial interests in nuclear fusion. Same idea. In many cases the technology developed for basic research (e.g. nuclear and particle physics in the 1920's) found its way into the consumer market later, but now it is the other way around. Also regarding military spending - that technology developed for warfare contributes as well. Obviously if we stopped all military spending and had societies that made this unnecessary, and then gave everything to space explorations and related fields it would improve progress noticeably, but it's not a simple 1:1 correspondence and it may not be AS good a reallocation of funds as you think.

The universe isn't expanding faster than the speed of light but if you take 2 points that are far enough from each other space will always expand faster. Taking the last example. If something can only travel at 1.000.000 meters in the time it takes for that +1 cm to occur it will always find itself at the 100.000.000 mark.

[@draganoiugeorge6010]

Taking the same 2 points with the same circumstances if one of the point were to move away from the other, even by a fraction of a millimeter the 2 point would move away from one another faster than the fastest speed. in our universe the max speed is aprox 300.000.000 meters/ second.

[@emrek99205]

There is something that has never been publicly addressed in any topics about light speed. Being near (or being) a massive object slows time for you. Going fast also slows time for you. The closer you get to the speed of light the more massive you become. "Speed of Light" like any speed is a distance over an amount of time. So if you were to go close to the speed of light, your travel wouldn't change but the time it took would definitely change and become less. This would end up being a boost of speed (which is a ratio), wouldn't it? Also if you become more massive due to your speed that also would slow time and in turn increase your speed. Speed of light doesn't become a limitation or barrier, but it instead becomes a hole that sucks you in if you get close. A bad, but mundane, analogy would be the speed of a log at the top of a waterfall. The closer it gets the faster it goes. Also the more water it interacts with that pushes it over the edge even faster. I'm just not sure that I believe the concept that to get to the speed of light requires infinite energy. Seems to me that there is a lot that wants you to move that fast. And just like going over a waterfall, it would require more to NOT speed up.

If we can figure out autonomous automation, space mining, and how to process & refine & manufacture in space. We could send an autonomous expedition to the Centauri system. From there we could send back data about the system, and figure out if it’s worth sending people. If not, we just repeat that with other systems until we have a system worth sending people to.

Not sure what you mean by worth it. For starters we have an entire sun and system here to exploit for energy and resources for eons to come.
