Summarizing Time Travel

In this following summary I’d like to share an experience which you all might be aware of. Once, Stephen Hawking arranged a party on the occasion of his birthday for the time travellers but then he announced that the party was a failure due to cause of absence of the time travellers from the future; even though he had arranged a party according to “their” time.

At first, in this topic, is discussed a story about a brilliant mathematician of his time who had fallen in love with himself, but his future personality had a sex change and become a woman. So, the idea of living in multiple dimensions (more than 3, in this case), travelling time back & forth, and to be your own parent/offspring is physically almost impossible and destructive for the instance.

And the quote about god and time by St. Augustine are really highly sensible. But if one is not constrained with time, then that person must be living above the four dimensions as we consider nowadays time as a 4^th dimension.

Here, some extremely important glitches about this are mentioned. It’s said that we cannot (or should not) go into the past as we would try to re-write our history and possibly exterminate our own race which is currently existing. However, the future travel is mentioned, that too, with a spoiler. We should not tamper with the future because our “present” is their “past” so it is highly probable that we commit a mistake and trap ourselves and others into a never- ending loop. That technically means we would be alive even after being dead after a regular lifetime. This idea sounds really too absurd to believe or even exist at all.

Although, there could be model suggestions for the time travel as the study goes on anyway regarding this topic.

1) Wormhole:  A] According to Einstein, let there be two distant poles in the universe who are connected by different states of time. (quantum entanglement is to be referred here). If anyone is able to connect those infinitely distant points for an instant and to move away by an infinitesimal amount, they would technically be present even before they left. But having a practical journey through a black hole for now and maybe, for eternity, is impossible, since we just cannot warp ourselves through a singularity and come out from the other door (the whitehole concept) without a scratch. We cannot even survive on the event horizon as time exactly stops there and so would light and everything else, including us. And anyone dared step beyond, they would disintegrate to subatomic particles within no time.

B] The second approach could be us connecting two poles on earth at a sufficient distance and charging them with say 10¹⁷ volts or 10²⁰ eV. With this energy of beams colliding to each other, we might be able to create a wormhole into space time fabric for a limited time.

2) From spinning the universes.

3) Using the possibilities of string theory.

Although, my opinion suggests following more possibilities:

As per this progressive timeline model of the universe, we’re somewhere in the present time frame. If by chance, we’re able to bent the entire timeline like a horseshoe, and place a wormhole anywhere we want, we can possibly travel through those two points as long as the wormhole is stable. This is all but a hypothesis and no model or experiment as of now is sufficient enough to build a structure or to convert an existing structure like that. The curvature of universe is an arguable topic because scientists have mentioned that the diameter of the universe (observable) is around 93 billion light years, or simply build a device to overcome the speed of light and explore the possibilities.

Actually, a lot of research is supposed to be there before placing a final verdict on the topic not limited to our single universe. If we maybe able to travel the time and thereby, defying the laws of physics a they’re now, we might explore what we could never explore.

(Note: The exact nature of time should be found out for its better understanding. We all are aware of wave particle duality of light; the time might have the dual or multiple nature in this case.)
