What Would Happen If You Traveled At The Speed of Light?

If you travel at the speed of light, your mass will increase exponentially. The speed of light is 300,000 kilometers per second (186,000 miles per second). When you move at this speed, your mass will become infinite. Therefore, infinite energy will be required to keep you moving, which is impractical. That’s the reason why no person or object can move at speed or faster than the speed of light. However, if we’re talking about going almost as fast as the speed of light, say 90% of the speed of light, then there would be interesting observations. For one, the person traveling at such a speed would experience a slowing of time. For that person, time would move slower than for someone who is not moving. For example, if a person is traveling at 90% of the speed of light, that person would experience only 10 minutes of time passing, while a stationary person would have experienced 20 minutes. Time will be cut in half! Also, the field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which the person is traveling.
