Time travel

Stephen Hawking organised a time travel party in 2009

A time travel party organised by Stephen Hawking in 2009.

This was an experiment that Hawking conducted to test the possibility of backward time travel. He invited people from the future to attend a reception at his university, but he did not send out the invitations until after the party. He hoped that someone from the future would find the invitation and use a wormhole time machine to come back and prove that time travel is possible.

However, no one showed up at his party. He said that he liked simple experiments and champagne. He also said that he had experimental evidence that time travel is not possible. He explained that warping space and time could trigger a bolt of radiation that would destroy the spaceship and maybe the space-time itself.

Is time travel to the future possible?

Based on the current scientific understanding, time travel to the past seems to be very unlikely, if not impossible. There are many paradoxes and inconsistencies that arise from the idea of changing the past.

Time travel to the future, however, may be possible, but only in a limited sense. According to the theory of relativity, time passes at different rates depending on the speed and gravity of the observer. This means that someone who travels very fast or near a massive object could experience less time than someone who stays still or far away from the mass.

Time dilation

This is called time dilation, and it has been experimentally confirmed. However, this does not allow the traveller to return to their original time, as they would have aged less than the rest of the world.

So, in summary, time travel is unlikely, but it is acknowledged that there are some intriguing possibilities and mysteries that remain to be explored.

Never say never!
