Thanks to Einstein, we know that the faster you go, the slower time passes–so a very fast spaceship is a time machine to the future. We’ve all heard of the speed of light, but what about 99% of the speed of light? It’s still incredibly fast, and it’s the kind of speed that can take you to the future.
The speed of light is 299,792,458 meters per second, and 99% of that is 2,978,924,572 meters per second. That’s almost three billion meters per second! To put that into perspective, it would take a beam of light just over one second to travel from the Earth to the Moon. At 99% of the speed of light, it would take just over 0.01 seconds.
At 99% of the speed of light, a spaceship would be able to travel to the nearest star, Proxima Centauri, in just over four years. That’s a long time for us, but for the passengers on the ship, it would feel like just a few months. That’s because time passes more slowly for them than it does for us.
Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth. That means that if a person were to travel to Proxima Centauri and back, they would return to Earth 36 years in the future. They would have experienced only five years of time, but everyone else on Earth would have aged 36 years.
It’s hard to imagine what it would be like to travel at 99% of the speed of light. The ship would be so fast that it would appear to be standing still from the perspective of an observer on Earth. But from the perspective of the passengers, they would be moving incredibly quickly.
The ship would also experience some strange effects due to the speed. For example, the ship would be shorter in the direction of travel than it is in the perpendicular direction. This is because time passes more slowly for the passengers, so the ship appears to be compressed in the direction of travel.
The ship would also experience time dilation, which means that time passes more slowly for the passengers than it does for observers on Earth. This means that the passengers would age more slowly than people on Earth, so when they return, they would be younger than everyone else.
It’s incredible to think that 99% of the speed of light is fast enough to take us to the future. It’s a speed that we can only dream of, but it’s still within the realm of possibility. We may never be able to travel at 99% of the speed of light, but it’s still fascinating to think about what it would be like.
Time travel is a fascinating concept, and 99% of the speed of light is a speed that can take us to the future. It’s a speed that’s almost impossible to imagine, but it’s still within the realm of possibility.
