Fun Fact, in 1997 a screenplay was anonymously submitted to Warner Brothers Studios, it was a Disaster movie called 2020: The Year the Shit hit the Fan, it involved a global pandemic originating out of China, a horribly botched response to the pandemic which began a domino effect of society falling apart mainly through corruption and sheer incompetence at every level of government, had people attacking each other over toilet paper, stores and banks demanding customers wear face masks to be allowed to enter, the entire economy was just "stopped" and the President of the United States was a Reality TV star with dementia who was telling people to inject themselves with bleach to avoid getting sick as riots and protests broke out in every major city while everyone else was stuck in their homes with glass rectangles glued to their faces giving them regular dopamine hits. While it remains the most solid evidence of a time traveler trying to warn us of what was coming, no one ever heard of it because it was considered too ridiculous, overcomplicated, and nonsensical. And besides, Y2K was gonna be the end of the world anyways.

The first rule of time travel, is: 'NEVER tell anyone you're a time traveler, or otherwise allow it to be found out.' Stephen Hawking once advertised and threw a party for time travelers, to see if anyone would show up to prove, or disprove the possibility of time travel. But he never could have checked with everyone who passed by on the street at the appointed hour, or who may have sat in nearby pubs, possibly drinking a quiet toast to a man they dare not meet and for a party they could not attend...

@@timm4811 Well this is more than hard science, I mean the electromagnetism theory. It is pretty pretty sure that that's the speed of light. Also everywhere and no matter how we move around, from everywhere the light is measured to have the same speed, no matter, the frequency. The frequency is red shifted, when we talk about galaxies, out of the Laniakea Supercluster (our own cluster, not galaxy). The far they are, the more the red shift in frequency (towards IR). So it is hard to doubt that, it will take a lot of work and it is not gonna be handy, either. I mean relativity is so nice because you don't have to use, all those complex space references, instead only one thing is constant, SOL and space and time are relative. The problem is not if it expands, but, how it expands, is it uniform? It starts to seem doubtful. That, you can doubt, with current data

@@tasosparisinos6893 So called 'Red Shift' is simply weaker, less energetic light, not necessarily farther away. A professor from Tel Aviv, at Cal Poly, froze light momentarily, slowed the light beam down enough to embed information,when released the light came back up to speed carrying the information to target. Also "most' red-shift has been found to be digital, rather than a smooth transitional event, indicating something other than distance alone to be involved.

With regard to FTL time travel- the solar system itself is moving, and without knowing the numbers, I would presume the Galaxy is moving at near-relativistic speeds itself, or at least very fast, so it doesn't seem like the idea of coming back to the same place really means anything at all.

The furthest reaches of our universe appear to be racing away from us at speeds up to and at the speed of light, does this appear the same in viewing from the outward locality looking back. I seem to see a relevance in speed unique to the viewer if this applies, no? At the furthest reaches outward of our universe due to expansion, as I've read many times, galaxies are moving outward at the speed of light or close to this, given a person in this location, who would not be moving seen from their perspective but see perhaps us moving away from their location, the concept of motion becomes very relevant, does the speed of light restriction appear in place from both locals?The idea "someone from the future" is taken seriously seems ludicrous, if we are the present than the future has not happened and as such does not exist yet so no one can "come from the future" without it being a convoluted science-fiction story or we are not in the present and if we are not in the present we have no prescience.

The Milky Way Galaxy moves through space around 2.1 million kilometers per hour. This came from a scientific paper that appeared first when I googled up the speed of the Milky Way Galaxy through space. I think what you are stating is not just the visible universe. The universe beyond our vision is only one theory among many concerning the speed of light and the movement of mass through Einstein's spacetime. I am starting to find that when people talk about a "time machine", they are only talking about time. If you want to go back in time to a particular time and place? Let's say that you want to go back in time so that you can go in your front door the day before. Your machine takes you back in time to the day before. How does your machine go back fifty billion kilometers to that point in space where your front door and the planet Earth were twenty four hours before? Finding the answer to that conundrum might help.

Time travel can easily be falsified by the conservation of energy. Leg. If we could send an apple into the past located nearby the apple as it existed at that time, we then have ask the question of where the atoms came from to allow the two apples to coexist in the same time frame. It would require that protons, neutrons, and electrons would have been spontaneously created out of nothing to appear suddenly next to the preexisting version of the same particles. In essence, you have to replicated existing particles somehow from the perspective of an observer of the now two apples.

[@Laotzu.Goldbug]

To be fair, this is really only true it given to a strict classical Newtonian interpretation of mass and energy. Considering everything we don't know about basic matter, never mind seems like dark matter and dark energy, it would be perfectly possible that some kind of Time Machine would drawn or influence that more subtle layer of the cosmos, and effectively shift around that matter and energy as needed, depending on where something pops into existence, without violating the fundamental conservation of energy for the complete universe as a whole over it's entire lifetime.

[@MrVibrating]

The practical factors enforcing c for massive objects relate back to those enforcing the conservation of momentum, and in turn, the conservation of energy. Taken as F=mA, Newton's 2nd implies the necessity that forces may only meaningfully be applied between inertias - that there can be no application of work by unilateral forces as from thin air - and thus in turn seguing into N3; reciprocity of the resulting counter-momentum.. whatever the ratio of interacting inertias, the change in inertia times velocity product in each direction is equal and opposite at all instants, hence the net system momentum always remains pegged at 'zero'. This 'zero momentum frame' likewise thus sets the shared inertial reference frame for any resulting PE or KE metrics; in the former case we typically multiply force and displacement, and for the latter we take the inertia times the velocity squared: in either case, distance and velocity - being intrinsically relative concepts - are relative _to_ whatever body constitutes the counter-inertia that is being accelerated _against,_ and this sets the symmetry of PE to KE plus losses, or input vs output energies. To put it another way, the conservation of energy is not a fundamental law unto itself, but rather an epiphenomenon of the more fundamental time conservation of momentum. Ask yourself however why it is that KE squares with velocity.. why, at double the speed, do we have four times the KE, rather than just twice as much, per the case for momentum? The answer turns out to be N3 again; the distance over which a given force must be applied in order to maintain acceleration is squaring with the rising velocity between the two interacting inertias, ie. between the body manifesting the desired momentum gain vs whatever's embodying the reaction matter and counter momentum. Thus, the squaring nature of energy with velocity is seen to be intrinsic to the means of raising it this way, in accordance with the seemingly-inescapable practicalities of Newton's laws. Except of course we're not really 'raising momentum' as we've already noted - the change in net system momentum when accelerating this way remains nil at all times. We don't 'buy' momentum with energy, but merely rent it, and the more we hire the greater the unit rate.. the economy of scale in this case favouring lower values of relative velocity, where the unit energy cost of momentum remains at its lower bounds.. For a 1 m/s acceleration of 1 kg, that works out at half a Joule (KE=½mV²). What if we could somehow accumulate momentum at that fixed unit energy rate? Net cost of accelerating 1 kg to c would be ½c J - that is, half lightspeed in m/s, expressed as Joules.. ie. a finite amount. To fix the unit energy cost of momentum this way, we must forego the factors causing it to square with relative velocity. That is, we must source and sink momentum directly to fundamental force constants and time; ie. ambient quantum momentum via time-asymmetric gauge boson interactions, gaining or losing momentum equal to the per-cycle I/O time delta multiplied by whatever the given force constant, these reducing to +/- dp/dt constants. This accumulates absolute momentum at a constant, speed-invariant efficiency, generating a divergent inertial frame and breaking CoE with all other FoR's.. Note that this exploit still _depends upon_ the time-conservation of momentum, albeit now held over a barrel..

[@100percentSNAFU]

If it were possible for a human to create a vessel to travel at the speed of light, theoretically, the occupant could go anywhere in the universe instantaneously (from their own perspective) as time would slow to a stop, correct?

[@olympicgardencrafts]

47:49 we could have a situation where we discover life (on Mars for example) and there is a debate for awhile over whether it's truly alien (or contamination) because of how close it is in relationship. You have 3-4 billion years of microbe evolution on Earth, during which panspermia between the planets could have been active. What if we discover Martian microbes and it shares a root DNA, or what if it's even older than our microbial life (frozen in time so to speak)? Perhaps the question we should be asking isn't whether or where we discover "alien" life, but how different will it be in relationship and how will we then be able to draw a genetic tree for our Solar System?

[@slydesplaylists]

These are long sentences warning, so thoughts anyway. Superluminal might be a better description than FTL because as what we think of as black holes are really observable from as the Dr described as local system relativity. There's not many SPL's however the quantum field of passing light constant momentarily through aquatic gas magnetic cloud ,utilising hydrogen fusion and Field Disruptive Magnetism to perhaps move the Hydrogen medium and C rads over a proportion of the craft or in it's wake,to whatever is necessary for a collective closed cycle velocity amplification.That and mass breaking into the direction of entropy are unknown progect's.

No, Cherenkov radiation is formed only be beta particles (high speed electrons) traveling through water faster than photons travel through water. The beta particles form a shockwave of photons as they collide into the back of them pushing their way forward. The photons are pushed forward and aside with some of the energy of the beta particles and are boosted to higher energy by the collisions, hence the lovely blue glow.

Abiotic chemistry creates the conditions for self forming membranes in the presence of nucleotides and amino acids. Since these are ubiquitous ingredients it stands to reason it happens everywhere it can. So few species evolve civilization here on Earth, like one we think (if you call this civilized) out of millions... so we are dealing with the rareness of advanced enough civilization to reach us and to happen to strike out in our direction. DNA and life can be everywhere and still not have much of a chance of finding us.

Here's an interesting thought I had while listening to this : If time travel is possible, then we need to consider that any civilization reaching that level of technology would try and find the most suitable "time" and relocate there. It could be an answer to the fermi paradox ; any advanced enough civilization already moved to a better place, but also a better time. Reaching that ideal place and time could be that "thing" you need to accomplish before any advanced civilization make contact with you.

Glad you liked it. Dr. Nemiroff is great.

It isn't the speed of light, it's the speed of causation.

[@askani21]

Anyone knows a good hard scifi novel? Something scientifically accurate, with convincing scientific speculation about physics or aliens, etc. I loved Cixin Liu's Three-Body Problem trilogy, I'd like something in that genre.

[@1966human]

What about observation isn't that faster than the speed of light, or is the light traveling toward the observer

[@channelwarhorse3367]

Curveing time and space per center, which controls the projection of energy content, the Observer would only see if the operator of gravity induction engine wants you to see. Rs, dangerous.

[@sarahs8371]

Extraterrestrials are most likely here, scary but true imo.

Hey John! I love your videos so much and I hope you’re doing well. I had a quick question for you, Have you considered creating a podcast for these episodes? I would love to listen to Event Horizon on Spotify or some other podcast service. Just a thought. Hope you are doing well! With love from Colorado!

[@EventHorizonShow]

EH team here. First off, thank you OG for watching and we’re glad you enjoy the show. We are working on a premium podcast version of the show which we will be announcing fully soon.

[@420PunkyOG]

@@EventHorizonShow Absolutely! I have loved this channel since the day I stumbled upon it ^̮^ and man am I excited for that podcast! Couldn't be a better time for it considering current events with COVID-19. Congrats to everyone at EH on the hard work! \ (•◡•) /

[@askshawn1533]

Natural light is, therefore it has no speed, you can only block it with solid objects or obscure it with semi transparent mass. That's my opinion only.

[@MarkAntony01]

Said this about 10 years ago. The line between dark and light is possibly faster than light. The dark is always in front of the movement of light. Documented it about 5 years ago. Old news. Keep up ;) Isn't it just a case of the light filling up the dark space?

[@DogsaladSalad]

i was just reading the comments hoping more people would point this out. not exactly groundbreaking stuff.

[@channelwarhorse3367]

Sub g or c to zero does not mean G does not exist entangled. G is a particle?

[@erictaylor5462]

30:00 I don't agree. If you believe time travel is impossible, to address this question scientifically you should try to disprove that belief by looking for evidence of time travel. If you look carefully and fail to find any, then you can become more confident that time travel is impossible. If you do find it, then you can conclude it *IS* possible and stop being wrong in your belief.

[@warrentreadwelljr.treadwel2694]

I have wondered about the interaction of two black holes, the area between them where space time is warped outside the event horizon of both black holes.

[@robertweekes5783]

A laser will not project a faster than light beam across the moon. It will only spray a rapid stream of photons that _spread & scatter_ across a surface *at* the speed of light

[@SP-bt9mp]

Thanks! I just looked up Miguel Johnson on Spotify. Lots of good tracks 😃

[@UpcycleElectronics]

Thanks for the interesting upload! I wasn't a fiction reader a couple of years ago. Watching content on physics, cosmology, and astronomy got me to start reading scifi. I started with the original Dune series. Surprisingly (to me), I've slowly made it past the first 2 books and am presently 2/3rds of the way through Children of Dune. Obviously, the Science in SciFi isn't paramount to my motivation. However, I am now quite curious to see if/how Event Horizon influences John's writing...no pressure :-) Thanks again for the upload. -Jake

[@HomoSapienMan]

Read three body problem first book of cixiun lu remberance of earth guaranteed to blow u away. Recommended by both Obama and zuckerberg. Sci if won’t ever be the same for u again

[@markokrsmanovic2562]

Great episode, much respect for the guest. Btw John, in one of your shows a guest and you spoke briefly about these plasma based organism like things, my question is would you consider a show based around those. Btw, I'm not a time traveler I'm just rewatching older shows.

[@mitcharcher7528]

That’s exactly what a time traveler would say. ;)

[@187mrsmith]

Who else be watching these type of videos to help themselves fall asleep

[@alanheadrick7997]

Something I wondered about is a ship traveling at maybe 10 to 20% the speed of light. Now space is not a total vacuum, there's dust and some gases, denser around nebula's. So I'm thinking as a ship traveling through this would create some sort of glow. Maybe around the nose, but maybe it could look like a glowing comet. Not sure. Maybe it would be bright enough to see with modern telescopes. Just a random thought.

[@HotPinkst17]

It would need some sort of navigational shielding field to deal with all the micro collisions or the ship would ablate to nothing in the star dust.

[@jonathanlindsey463]

he is talking about tacyon particles but not saying it because they have never been proven... why to photons “which r massless” travel at the speed of light? why do they not accelerate? they leave the sun at that speed instantly, u would think if they do that then they should accelerate but they do not, because there is a limit.. even in a space that is expanding faster than light speed objects in that space do not violate the light speed limit, why?

[@xyo1337]

@6:50 - The line that you refer to doesn't move faster than light. Light occupies a space which gives the appearance of there being a line that moves. Essentially the shadow is removed by the presence of light. That doesn't mean shadows move faster than light. Or am I missing something here?

[@cedricvillani8502]

I would test a person or object from the future to see if the Carbon Date is negative lol

[@celestromel]

Great images - loved them

[@andymouse]

Has a Photon got any mass or not ? what does " a tiny bit of mass " mean ?

[@Psnym]

andymouse123 photons are massless

[@ConnorwithanO]

photons have no rest mass. But since energy is equivalent to mass, the energy that a photon carries gives it dynamic mass. Which is why light can exert force and interact with gravity.

[@pyrolopez854]

Lightspeed is too slow you guys have to go to ludicrous speed!

I would be OK with Ridiculous Speed, Ludicrous Speed is to scary! No safetybelts required!

Welcome to the Program

[@evihofkens9530]

Instead of c = the speed of light, we should call it the speed of causality (c of causality) because when you're at the maximum speed, time doesn't pass.

[@noname117spore]

Honestly, I want to debate "are we alone" being the biggest question in human history. There's at least one question which is bigger. And that is "why does existence exist? Shouldn't nothingness be easier and thus the state of everything?"

[@philaypeephilippotter6532]

Oddly enough your _nothingness_ (a perfect word for the concept) is apparently very unstable. This makes sense to me as existence _does_ exist - _vide._ *René Descartes.*

[@nkordich]

There's a point in Tom Stoppard's play, Rosencrantz and Guildenstern Are Dead that goes: Rosencrantz: We might as well be dead. Do you think death could possibly be a boat? Guildenstern: No, no, no... Death is...not. Death isn't. You take my meaning. Death is the ultimate negative. Not-being. You can't not-be on a boat. Rosencrantz: I've frequently not been on boats. Guildenstern: No, no, no--what you've been is not on boats.” The 1990 movie with Gary Oldman and Tim Roth is excellent, and very easy to recommend to anyone pondering existence - and non-existence. Getting back to the point, as per the weak anthropic principle, Rosencrantz unintentionally had a point: he might have not-been on boats more frequently than he'd been not-on-boats. Using the same Bayesian inference that is used to suggest in simulation theory that we're one of many simulations rather than our original selves, there may be an infinite amount of time during which we didn't exist versus the finite time in which we do exist, so while it might be the case that nothingness *is* easier and is *usually* the state of everything at a ratio of infinity to one, it seems we are currently experiencing the one where we exist as opposed to the infinity where we don't. Or maybe we're 'experiencing' all that non-existence concurrently and just don't notice because, by its nature, the experience of non-existence is nothing to write home about.

[@HardRockMiner]

The Kinman Dwarf star which is roughly 100x larger than our sun vanished without a trace recently. Any chance of doing something on that..?

[@nkordich]

Probably just dust. Not on the telescope, that is, but dust being thrown off by the star. It's a massive, unstable blue giant star in the Kinman dwarf galaxy (as opposed to a dwarf star). It's been speculated that it could have collapsed into a black hole without going through a supernova, but the dwarf galaxy is so far away we can't resolve other stars - it's possible it passed behind an obscuring mass, or entered a late-in-life phase where it sheds massive amounts of dust. As stars of a certain size burn through their hydrogen, helium, and oxygen, it will start generating carbon - a *lot* of carbon - more carbon than the total mass of the Sun. This is referred to as dust, though the exact size of it may vary - from a few atoms to macroscopic soot. We've seen other stars vanish from view as the carbon dust billows out. It may remain visible in certain frequencies, but at 75 million light years, it's not one of our closer neighbors. We'll have to wait and see - it might reappear, if it's just obscured, or we might see a flash if it's on the verge of going nova, or it may throw off radiation if it's become a black hole and interacts with matter around it.

[@brynduffy]

John, it would be best to explain to your audience that the speed of which reality happens is the speed of light. The speed of light is the speed of causality. In this sense, backwards time travel is nonsensical. You would have to reverse everything everywhere to move backwards in time which would be the same as moving faster than the speed of light.

[@MS-qm3ml]

omg i forgot about seeing the stars in 2017!! what a spectacular experience
