British physicist (physicist) Jim Al-Khalili has questioned the efforts of billionaire personalities to live forever, saying that instead of an unlimited life, man should focus on spending his limited time in a better way.

Jim Al-Khalili says that physics has changed the common human understanding of time, according to Einstein’s theories, the speed of time is not the same for everyone, but the effect of speed and gravity can make a difference.

He explained that a second may be of different duration for a person traveling at high speed than for another person, while strong gravity also changes the speed of time.

Physicists said that traveling to the past is mathematically possible under certain conditions, but this can lead to many complex inconsistencies, while traveling to the future is theoretically relatively easy, which can be done at speeds close to the speed of light or with super-strong gravity.

Jim Al-Khalili has revealed that I will also discuss one of the great mysteries of time, the passage of time in only one direction.
