What would happen if you were hit at the speed of light?

It travels at a steady rate of 186,282 miles (299,792 kilometers) per second. Even if it were physically possible to propel ourselves to such speeds (spoiler alert: it isn’t), as you gain the necessary momentum to match the speed of light, your mass would become infinite.

Can a human punch at the speed of light?

As a result, you would need an infinite amount of energy to match the speed of photons traveling through a vacuum…that’s kind of impossible. Humans just aren’t built for that kind of thing (and that’s not even taking into account what would happen if someone hit the brakes suddenly).

Can a grain of sand destroy the earth?

So if a grain of sand managed to travel at the speed of light so the entirety of its mass converted into energy, it would only be the equivalent of 236.6 tons of explosives. Not enough to destroy the earth.

What if an object travels at 90\% of the speed of light?

On the other hand, if an object traveled at 90\% of the speed of light, then its mass would be 2 times its original mass. Can we travel at the speed of light? No, we cannot travel at the speed of light. You see, if an object travels at the speed of light, its mass will increase exponentially!

Is there anything that can travel faster than the speed of light?

No, there isn’t. As an object approaches the speed of light, its mass rises steeply – so much so that the object’s mass becomes infinite and so does the energy required to make it move. Since such a case remains impossible, no known object can travel as fast or faster than the speed of light.

What is the relationship between speed of light and mass?

It means that if an object moves at a velocity that is 10\% of the speed of light, then it would experience an increase in its mass by 0.5\% of its original mass. On the other hand, if an object traveled at 90\% of the speed of light, then its mass would be 2 times its original mass.

What would happen if you flew on a rocket traveling 90\% light-speed?

If you flew on a rocket traveling 90 percent of light-speed, the passage of time for you would be halved. Your watch would advance only 10 minutes, while more than 20 minutes would pass for an Earthbound observer. You would also experience some strange visual consequences.
