June 28, 2009, Steven Hawking had a party at the University of Cambridge. Except, no one showed up. That was because he invited everyone after the party had ended. This was somewhat of an experiment to show that time travel couldn’t be possible. But mathematically, time travel could be possible. Luckily, paradoxes like the grandfather paradox can be avoided. But if closed timeline curves “Time Portals” don’t exist time travel would be impossible.

The author/s supported time travels possibility with facts but was leaning toward the fact that time travel is not possible yet or ever. I thought that time travel is impossible, because time isn’t something we can physically change. It is something we don’t know much about, so to physically take someone/something to a time in the past or future is impossible. My parent is confused about how it would mathematically work and not physically work and does not believe time travel is possible.
