can we move faster than light?

As an object approaches the speed of light, its mass rises precipitously. 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.

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. Take, for instance, the expansion of the Universe itself.

No material particle can move faster than the speed of light in vaccum. ... Only electrons can move faster than speed of light in a material medium. Heavier particles cannot move faster than speed of light in the medium. This phenomenon is responsible for the emission of a visible radiation called Cerenkov Radiation.

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.

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).

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.

Time on Earth moves FASTER than in space: Planet's orbit around the sun and galaxy gives us one second less per WEEK. One of the consequences of living in our universe - where space and time are linked - is that as you travel faster, time can appear to speed up.

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.

So the faster something travels, the more massive it gets, and the more time slows – until you finally reach the speed of light, at which point time stops altogether. And if time stops, well then, so does speed. And so nothing can travel faster than the speed of light.

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.

John Houston, Learned lots of physics through KSB. According to Einstein, no information can travel faster than the speed of light. ... According to Einstein, no information can travel faster than the speed of light. However, let's imagine for this example that electricity does in fact travel at the speed of light.

Nothing can travel faster than the speed of light. But if it could , the conventional wisdom goes, it would travel back in time. ... We used only the velocity addition formula from special relativity, as the other ones (time dilation, length contraction, etc.)

"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.

Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the "speed of light"; nothing can move faster than the speed of light.

Gamma Rays May Move Faster Than Light, Causing Them To Go 'Backwards In Time,' Say Researchers. Two years ago, researchers made the amazing discovery that in some specific instances in space, gamma-ray burst pulses repeated themselves in a way that made it seem as if they were going backwards in time.

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.

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.
