Why time travel is impossible




















This would require a machine that could record every molecule in a given space and be able to move said molecules, and would require a ton of energy; I guess it's still a moot point but interesting to think about.

The way to grow wiser is by using your ability to reason. If you don't logically think things over then you will never understand anything. You will wander through life in a haze of abstractions and nonsense. It seems you have chosen your place in this world rather early, my friend. Thus you have decided that your understanding of this world would stop at the limit of your senses.

There are things far beyond your perceptions and understanding. In my existence I have seen much, yet I cannot claim I have seen enough. Seek to grow wiser than whom you are. Yes, just because people would remember erasers when they look at the picture does not mean that the actual erasers would exist. They would only exist if people started making new erasers again. You have this strange idea that a picture of an object is the same thing as the actual object itself. But that is not true at all.

I can draw a picture of a unicorn, but that doesn't mean that actual unicorns exist. Unicorns do not have a location in respect to other objects. Unicorns, gods, fairies, etc. In order for something to 'exist', it needs to have location. If it has no location, then it doesn't exist. No, you misunderstood me. Apparently you thought that what I'm saying is that 'all moments are happening right now'. But no, that's not what I said at all.

What I'm saying is extremely simple. I'm saying that there is no past, present or future. There's just things moving to different locations in space. That's all. Understand now? I am saying that there is no time. But I am not saying there is no past, present or future.

I am saying that past, present and future are concepts that refer to motion. You said that" if there is no memory, there is no past. If we add these two beliefs of yours together, this would mean that if there were no men, there would be no God. If no one were here to preserve the existence of God, there would be no God, as there are no physical manifestations of God in existence.

Is that what you believe? If to you there is "just a bunch of objects moving to different locations", then you will agree that these objects do no move over an advancing time scale -- since there is no measurable notion of time. If that's the case,you will also agree that these objects are moving simultaneously, regardless of "when" they have moved -- again, since there is no time.

So according to this principle, the Egyptian Dynasty is happening as this very precise moment, and so is the first human trip to Jupiter. Proof of what? If someone claims that the past is recorded, then the burden of proof is on them.

They're making a very fantastic and absurd claim which has no evidence to support it. Nope, only the picture exists. The erasers would all be gone and would therefore 'not exist'. Very simple. This is very contradictory. Because there is no past. I honestly don't think that what you're saying makes any sense.

On the one hand, you're saying that there is no past, future or time which I agree with. But then on the other hand, you're saying that it's "theoretically possible that no instant is ever lost in the past, and exists as an alternative present to the current present". Don't you see how that's a blatant contradiction? In reality, there's just a bunch of objects moving to different locations. I know that might sound boring.

But that's just the way things are. Well, nothing discussed here can be flawed as none of us hold material proof of our assertions. You may however say that you disagree with me. And that's because you keep looking at things on a linear perspective. Not the locations it was at when I took those photos. We have learned to understand and interact with things based on their observable material qualities. Should all erasers in the world disappear simultaneously, and the only proof of an eraser's existence becomes your picture, then an eraser still exists.

Only, it has lost its physical properties to become something else. Now you would be correct saying that, going forward, our life - this life - doesn't have any recorded frames.

However since there is no past and no future as there is no concept of time, only motion, it's theoretically possible that no instant is ever lost in the past, and exists as an alternative present to the current present.

This would mean that time travel does not require you to "advance" or "go back" on a linear scale. If the scientists are right, then when two black holes merge and create new space, they should also create new time one millisecond, to be exact which would delay the gravitational wave signal LIGO observes from Earth. Muller is optimistic that in the next few years LIGO will verify or falsify his theory.

This way of time travel is too twisted to be real unless you take avengers end game time travel so serious that you believe you can go back in the past and fix your mistakes but what kind of life would it be if we can fix our past mistakes and perhaps even control the future. Life is more meaningful if we cannot control, manipulate or predict our future and past and where would religion come into the picture when we can time travel and manipulate life events to our own preferences.

Having a time travel machine for this would also imply time travel of physical objects is possible. By just going back a little in time and just changing one thing, for example; If trump never becomes president it means person x would be president and maybe Clinton would not be bothered by immigrants so you actually end up marrying one or maybe Africans may never accept missionaries and their colonial masters so they may never be enslaved?

Or going back in time just knowing exactly how and why COVID started would impact a lot of things today. So by just traveling back in time and changing one thing or knowing something can have a serious impact on almost everyone presently. Time travel remains possible in theory but the illogical outcomes of its success make it impossible. If it does, then the present and future and probably the past exist all at once.

From the constancy of the speed of light it follows, however, that space and time must not be absolute, but relative. A direct consequence of this is that time passes at different speeds depending on how fast objects move.

For example, a moving clock in a car moving at a constant speed ticks more slowly from the point of view of a resting observer who is not in that car. This is comparable to a journey into the future — even if the time difference between the moving driver and the resting observer is only a billionth of a second.

Millington explained the whole thing with the following example: "If I were to fly off at incredible speed in a spaceship and return to Earth, less time would pass for me than it would for everyone I left behind. Everyone I returned to would conclude that my life had run as if in slow motion — I would have aged more slowly than them — and I would conclude that theirs had run as if in fast forward.

Would it then be possible for us to travel back in time? The answers to these questions aren't straightforward. As Millington explained, the law of causality could no longer apply in such a case and we could no longer regard time as forward or backward. Moreover, the theory of relativity states that mass and energy are one and the same.

For all particles that have a "rest mass", this means that an infinitely high energy is required to reach and exceed the speed of light. So far, there are no known particles without a rest mass. However, as Stephen Hawking writes in his book, there could be a way time travel into the past may be possible: wormholes that connect two distant places in the universe. In Einstein's general theory of relativity, gravity is a consequence of the way in which mass warps space and time — mass distorts space-time and this in turn influences the movement of mass.

In physics, spacetime refers to the joint representation of three-dimensional space and one-dimensional time in a four-dimensional mathematical structure. If we squeeze in enough mass, spacetime becomes so warped that even light cannot escape its gravitational pull and a black hole is formed," wrote Millington.
