what will happen if you travel faster than light speed?

This was accepted in classical physics, and the special theory of relativity took pains to preserve the rule, despite the relativity of an object's motion. But if something can travel faster than light, it can travel backward in time, according to the theory.

Yes, light is affected by gravity, but not in its speed. General Relativity (our best guess as to how the Universe works) gives two effects of gravity on light. It can bend light (which includes effects such as gravitational lensing), and it can change the energy of light. ... The speed of light is still constant.

The closer an object gets to the speed of light, that object actually experiences time at a significantly slower rate. If the Enterprise were traveling safely at close to the speed of light to the center of our galaxy from Earth, it would take 25,000 years of Earth time.

"Nothing can travel faster than the speed of light in a vacuum." "Light in a vacuum always travels at the same speed." Those additional three words in a vacuum are very important. A vacuum is a region with no matter in it.

All electromagnetic waves travel at 300,000 km/s in the vacuum of space. ("Speed of light.") Nothing travels faster than the speed of light. The wavelength of an electromagnetic wave is the distance from one crest to another.

The faster the relative velocity, the greater the time dilation between one another, with the rate of time reaching zero as one approaches the speed of light (299,792,458 m/s). This causes massless particles that travel at the speed of light to be unaffected by the passage of time.

If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

The speed of light is the speed electromagnetic waves travel. The speed of light is 3.0 x 108 m/s in space. The speed of light is the same in all matter. The speed of higher frequency light slows down more than lower frequency light in matter.

Gamma rays travel faster than visible light. All electromagnetic waves travel at the same speed in a vacuum.

"Since nothing is just empty space or vacuum, it can expand faster than light speed since no material object is breaking the light barrier," said theoretical astrophysicist Michio Kaku on Big Think. "Therefore, empty space can certainly expand faster than light."

The speed of light is much faster than the speed of sound in air. If you want to compare, the speed of sound in air is ~ 343 m/s and the speed of light is 3x1010 m/s. In other words, light travels 186 thousand miles in 1 second, while sound takes almost 5 seconds to travel 1 mile.

Time Travel Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory. ... If the neutrinos really are traveling faster than light, then they should be time travelers.

Any object with mass accelerates, gaining energy, but it always needs more to accelerate further. So, propelling us to the speed of light would take an infinite amount of energy. ... So for now, at least, we won't be able to travel beyond the speed of light based on our current understanding of the laws of physics.

There is no limit to how fast the universe can expand, says physicist Charles Bennett of Johns Hopkins University. Einstein's theory that nothing can travel faster than the speed of light in a vacuum still holds true, because space itself is stretching, and space is nothing.

In other words, the faster an object moves, the greater its mass. ... If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

Light is the fastest-moving stuff in the universe. It travels at an incredible 186,000 miles (300,000 km) per second. ... Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.88 trillion miles (9.5 trillion km).
