can matter travel faster than the speed of light?

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.

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.

Warp Speed Travel Is Theoretically Possible, Says Astrophysicist. Despite all the intergalactic hopping in science fiction and the occasional extraordinary research claim, most of us have accepted that when it comes to travel, humanity is always going to be limited by the speed of light.

Simply put, the speed of light (c) is the fastest velocity at which an object can travel in a vacuum. As an object moves, its mass also increases. Near the speed of light, the mass is so high that it reaches infinity, and would require infinite energy to move it, thus capping how fast an object can move.

✔They travel slower than the speed of light, they include visible light waves. ✔ they can transfer energy through empty space. ✔ They need matter through which to travel, they travel at the speed of light. ✔ they include visible light waves.

Yes, wind can travel faster than the speed of sound. ... The speed of sound is not a fundamental speed like the speed of light is. The speed of sound just describes how fast a mechanical wave travels through a material. Different materials have different speeds of sound.

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. ... So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

Light doesn't need a medium to travel. The speed of sound through air is about 340 meters per second. It's faster through water, and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second.

Particles Found to Travel Faster Than Speed of Light. An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light.

Nothing travels faster than the speed of light which is 300,000,000m/s. That is a fact that arises from Einstein's special theory of relativity, and has been shown to be the case experimentally also. Light has the ultimate speed limit in nature.

The speed of sound through air is about 340 meters per second. ... Light will travel through a vacuum at 300 million meters per second. So they're totally different scales. No information can propagate faster than the speed of light.

Tachyons. 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.

So, simply going faster than light does not inherently lead to backwards time travel. Very specific conditions must be met—and, of course, the speed of light remains the maximum speed of anything with mass.

All electromagnetic waves travel at the same speed through empty space. That speed, called the speed of light, is about 300 million meters per second (3.0 x 108 m/s). Nothing else in the universe is known to travel this fast.

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.

Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. ... It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.

The theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that's immensely difficult to achieve and impossible to surpass in that environment.
