Curiosity: What If We Can Travel At The Speed Of Light

Traveling at a Speed Of Light would be really helpful for us to find other planets, stars, galaxies, and milky ways. It would also help us with further studies. But, traveling at a speed of light would be really dangerous if our equipment is not right and our technology is not advanced. Because when we can travel that fast, the equipment would experience an increase in its mass. The person who is traveling at that speed would also experience time dilation, in other words,  he/she would experience slowing down of time. But wait, there is more! The person who is in the spaceship would also experience a drastic change in his/her vision. Everything would appear as like you were looking through a tunnel-shaped window, causing an extreme Doppler Effect. This is known as an increase in the frequency of sound, light, or other waves as the source and observer move towards (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers. However, as the time goes by, everyday technology also advances, what if we've invented the right equipment for this and traveling at the speed of light would be really easy in the future.
