Is Past Present and Future happening at the same time?

Past, present and future they exist simultaneously, but in different dimensions. But the past does not “disappear”, it simply exists in different parts of space-time. This thought has a basis in the theory of unified space and time, proposed by Albert Einstein in 1915.

Is reverse time travel possible?

As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.

Does time have a beginning and end point?

Time has no beginning or end point, time is something that we apply to the Universe in order to make things easier to understand. As we currently apply Time to have began with the Big Bang, but as the Universe most likely existed before the Big Bang it doesnt really work as a true definer of the start of time.

Does everything have a beginning and end?

No. Everything is based on matter in motion. It is matter in motion that shows that there must be space and time, else motion would be impossible. Matter itself is eternal, it is infinite and has no begin or end. Therefore also time and space are infinite.

Why is there no end to space and time?

Everything is based on matter in motion. It is matter in motion that shows that there must be space and time, else motion would be impossible. Matter itself is eternal, it is infinite and has no begin or end. Therefore also time and space are infinite. No begin or end to space and time.

Is there an absolute begin of time?

The idea of an absolute begin of time (and space and matter) thus does not belong to physical reality, it is a doctrine from philosophy, that has been put in by hand by theoretical physicists… They claim that physical laws existed prior to the universe, and allowed the universe to create itself ‘from nothing’.
