are gravitational waves faster than light?

Scientists call these ripples of space gravitational waves. Gravitational waves are invisible. However, they are incredibly fast. They travel at the speed of light (186,000 miles per second).

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 principle, shadows can move faster than the speed of light. ... If the shadow is large enough, it could move across the surface faster than light. This is an illusion that darkness travels faster than the speed of light, and it is still agreed that no physical object can travel faster — since darkness has no mass.

Yes, light is affected by gravity but not directly. Gravity affects objects which have some mass but light particles do not have any mass so gravity cannot affect it directly. But it affects the space-time continuum in which light travels. ... Light has a fixed speed which doesn't change.

Can information travel faster than light? ... One of the tenets of Einstein's Theory of Special Relativity is that nothing can travel faster than the speed of light in a vacuum. Light speed is considered the universal speed limit of everything, and this is widely accepted by the scientific community.

Photons travel in harmonic waves at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the speed of light.

In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light.

And sometimes, these events only cause small, weak gravitational waves. The waves are then very weak by the time they reach Earth. This makes gravitational waves hard to detect.

Since electromagnetic waves always travel at the speed of light in their current medium we can immediately say that sound waves are not electromagnetic waves, since they travel at the speed of sound (≈334 m/s) which is much much less than the speed of light in air (≈299,700,000 ≈ 299 , 700 , 000 m/s).

For one thing, while nothing has ever been observed travelling faster than light, that does not mean it is not theoretically possible to break this speed limit in very special circumstances. ... There are galaxies in the Universe moving away from one another at a velocity greater than the speed of light.

A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. A gravitational wave is an invisible (yet incredibly fast) ripple in space.

Kopeikin and Fomalont concluded that the speed of gravity is between 0.8 and 1.2 times the speed of light, which would be fully consistent with the theoretical prediction of general relativity that the speed of gravity is exactly the same as the speed of light.

That velocity can exceed the speed of light in a vacuum, although under typical circumstances it does not. On the other hand, a pulse of electromagnetic radiation can never move faster than the vacuum speed of 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.

Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths. All of these waves travel at the same speed in free space, which is the speed of light or about 300,000,000 m/s (metres per second).

No. Radio waves typically travel at the same speed as light (they are both radio magnetic transmissions just at different frequencies). There may be some very slight differences depending on the medium being passed through but nothing significant.

Yes, wind can travel faster than the speed of sound. ... The only limitation on the bulk motion of objects with mass is the universal speed limit of the speed of light in vacuum. The speed of sound is not a fundamental speed like the speed of light is.
