Today I want to talk about time travel. Most people think time travel is impossible, and honestly, when it comes to going back to the past, they're probably right. We don't have a known method to do it. But traveling to the future is where things get interesting. According to Einstein's theory of relativity, the closer you get to the speed of light, the slower time passes for you compared to everyone else.

Think about The Flash for a second. When Barry runs, it often looks like the world around him is moving slower while he's moving normally. Real physics isn't exactly like that, but the idea is surprisingly similar. If a human could somehow travel close to the speed of light, time would pass more slowly for them than for people on Earth. While years could pass for everyone else, only a much smaller amount of time might pass for the traveler.

Imagine leaving Earth for what feels like a few years and returning to find that decades have passed. Your friends would be older, cities would be different, technology would have advanced, and the world you once knew might barely recognize you. In a way, that is a form of time travel to the future.

The problem is that getting close to the speed of light would require an insane amount of energy, and according to current physics, anything with mass cannot actually reach or exceed the speed of light. So the question isn't whether we can build a time machine like in movies. The question is: could humanity ever build something fast enough to let us experience the future before everyone else?
