Comments by "Digital Footballer" (@digitalfootballer9032) on "Neil deGrasse Tyson Explains Faster Than Light Interstellar Travel" video.

It's all about thinking outside the box. If there are indeed certain limitations and unbreakable laws of physics that prevent us from travel away from earth of any significant distance, then ways to "bend" the rules need to be discovered. The Alcubierre drive is an example of this, though of course it is purely theoretical. This is a very simplistic example when compared to space travel, but relevant in terms of making the impossible, possible through bending the rules. A Volkswagen beetle simply is not going to beat a Porsche GT3 in a quarter mile drag race, it is impossible assuming of course there are no modifications allowed, both vehicles are driven by skilled drivers, and both vehicles function properly and do not break down or crash. However, this was achieved when the rules were bent and the playing field was changed from 2 dimensions to 3. A beetle when dropped a quarter mile in the air from a helicopter will cover a quarter mile of vertical space quicker than a Porsche GT3 can cover a quarter mile of horizontal space under its own power. This was done by our friends at Top Gear. Again very simple, but completely changed the result when an extra dimension was added to the equation. Could the same be true in space if and/or when a higher dimension were to be discovered and possibly manipulated? A rocket powered ship is only going to go so fast, but if there were to be a "way around" through a higher spacial dimension could this be exploited? What's impossible in one dimension is not only possible, but practical in a higher one. On a 2D plane you can only go back and forth and side to side...up and down is not only impossible, but can't even be conceptualized by an entity living within that 2D plane. What impossible movements might we discover in a 4th spacial dimension, or higher? Traveling to another star system might be like walking from your living room to your kitchen. We would never know if higher dimensions are not unlocked. The problem is unlocking them, can it be done, and do they even exist? Some scientists think so, but again it is purely theoretical.

 @thuggeegaming659 The professor has spoken again. Don't argue with him, he got his doctorate out of a cracker jack box 😂

So in other words, will time dilate if such a method is used? It is believed that no, it would not, because by using such a method of travel (warping the plane of space, wormholes, etc) there would be no effect on time because you are not reaching relativistic speeds, you are simply taking a "shortcut" at slower speeds. Time is only effected when high speeds come into play, or you get into close proximity to a large gravitational force (e.g. a black hole). A wormhole or other "bend" in space is essentially like folding a piece of paper and coming out the other side instantaneously, you don't necessarily need to go fast to get there, you just drastically shorten the distance of the journey. It is theorized that we can produce man made wormholes, but the technology needed is well beyond our current capabilities.

In theory, time should not be effected by traversing a wormhole. In concept, you are not reaching relativistic speeds as you would need to do to travel from a point in space to another point many light years away in a human lifetime, rather, you taking a cosmic "shortcut". Real scientists, unlike our friend here above us in the comments, conceptualize this as being like at a point at the end of a sheet of paper, and to get to the other side you fold it in half and punch through the paper instantaneously rather than traversing the entire sheet. There are many good videos on the subject from leading astrophysicists, all of whom know just a little bit more than Mr. Cracker Jack up there 😂

I believe the work around used by Roddenberry and the producers of the series was that the occupants of the star ships were not actually themselves traveling at FTL speeds, rather they were standing still and moving space around them, therefore not messing with the time dilation that relativistic speeds create. Of course this is just fiction, but is a plausible theory if such technology were to be possible.

There have been countless science fiction pieces written on this concept and the psychological aspect is typically what the plot revolves around. There is also the concept that another comment mentions that as technology progresses and faster ships become available, each existing ship will become pointless and will be overtaken by newer, faster ships, making the older ones pointless. The only way I could possibly see this being feasible is if we were able to build a type of O'Neill cylinder capable of housing many thousands, maybe millions of people in a large earth like environment that could also travel at a significant percentage of light speed. Hard to conceptualize such a thing now, but someday maybe it would be possible.

It is theorized that the energy needed for such a task would require matter-antimatter annihilation which yeilds pure 100% energy with no waste or byproduct. So this of course would require us to firstly be able to create antimatter in enough quantity to achieve this, and secondly, a method to contain it. I believe at our current state of technology, we have created a few atoms of antimatter, so we have a long way to go, but certainly not impossible though extremely challenging and improbable.

@SJR_Media_Group yet* The only way this could be done is through harnessing enough antimatter. Could that be done? At our current level of technology, no, but in the future? It's at least plausible. We have been able to create a few atoms of antimatter, but we would have a very long way to go. Probably millions of years and reaching at least a Level II civilization (we aren't even at Level I currently).

@thuggeegaming659 Could you tell me where you received this magic "education" that apparently gives you greater knowledge than the top astrophysicists? It's strange, even they consider FTL to be at best extremely difficult and requiring exotic materials we currently do not posses, but not impossible. But you have deemed it impossible, because you know more than they do? Interesting. And on the subject of causality, if there were changes and discrepancies in causality you wouldn't even know it. History could be changing right under our noses and you wouldn't even know it, so you cannot with any degree of certainty deem it impossible. You could wake up tomorrow with a completely different history of the world than what it is now, and to you the observer, it would have always been that way. You would have zero knowledge of the other timeline. These changes in causality would simply create new timelines, not paradoxes because paradox by its very nature is impossible.

In space, nobody can hear you scream 😂

@asoka7752 Hopefully if we ever reach a level of technology where we can do these things, petty social problems like racial politics will be long a thing of the past and we will just send the most qualified individuals regardless of what they look like.

@thuggeegaming659 Well, you have spoken, you say FTL is impossible, so must be true because you say so and you know it all. It's not possible with current technology, but there are many scientists out there who are much smarter than you that believe it is possible with the right technology and the ability to harness certain exotic matter such as antimatter. Nobody is arguing that we aren't essentially now at a point in technology where we have just discovered the wheel and are talking about making rockets to the moon, which on the surface is absurd, but over the many thousands of years in between those discoveries we did eventually make it happen. Over the coming millennia nobody knows now what will be possible if we survive as a species and continue to advance. Nobody can sit here now and say with any accuracy what will be possible or impossible in the future, especially with the confidence that you, just some person on a random comment board, display.

Unless we had the technology to somehow control the wormhole, then likely yes you would be taking a huge chance that you just took a one way way trip with no way back.

FTL travel is not necessarily impossible, it would have to be empirically disproven in order to be deemed impossible. There are theories like the Alcubierre drive (essentially a Star Trek type warp drive) that may be possible, but require exotic matter/technology that we do not currently possess. Improbable is a better description at this time, maybe near impossible, but there is still a non-zero chance this is possible unless proved otherwise. It may very well be something that is possible in concept but could never be achieved because of human limitations. That's not to say a more advanced species doesn't, or hasn't already, achieved such a technology.
