1. Time Travel

• Chances We’ll See It: Low to High (depending on the version)

Time Travel might be the biggest of all science fiction inventions that people want to see. The issue with this is that doing the type of time travel you see in films is likely never going to happen. However, we already have a form of time travel where we can go further in time. Sadly, we do not have anything where we can go back yet.

Space-Time offers us the ability to leave Earth and go into a place like Space as well as other planets where time differs. In fact, two twins were studied where one went into space while another stayed on Earth. The “space twin” came back to Earth looking younger than his Earth-staying twin. Time moved the same but the twin, as far as his body is concerned, went forward in time without aging like his brother to do so. This proved that technical time travel using Space-Time is possible.
