Only if you are a photon. In that case, you always move at the speed of light.
If you're not a photon, and have any mass while you're sitting still, and are not
moving at the speed of light right now, then you can never attain light speed.
With current technology, it is not possible to even come anywhere close to the speed of light. For example, traveling at 1/10 the speed of light is still science fiction. On the other hand, for anything that does NOT travel at the speed of light, it is impossible to actually attain the speed of light. In theory you might get close. There are some particles, such as photons and the hypothetical gravitons, which ONLY travel at the speed of light.
As the speed of an object approaches the speed of light, its kinetic energy approaches infinity. An object moving at the speed of light would require inifinite kinetic energy.
No, it is not possible to slow down the speed of light in a vacuum.
For light, it is.
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
The Fastest speed possible in the Universe is the speed of light in a vacuum exceeding 299,792,458 meters per second.
no
Yes, according to our current understanding of physics, the speed of light in a vacuum is the fastest speed at which energy, matter, and information can travel. Any object with mass that approaches the speed of light would require an infinite amount of energy to accelerate further.
The speed of light is around 86,000,000 miles per second and there is not anything that can attain nor exeed that speed. It has been sugested that the power of thought may reach such a speed but has never been proven.
You can't attain the speed of light. Since you've already postulated that impossibility in your question, go ahead and postulate whatever consequences appeal to you. We won't mind.
It's not possible to transport matter at light speed, and you can call it anything you want to.
It is not possible for any object with any mass to travel at the speed of light. It is possible to travel at 99.9999999999999999999999999999999999999% the speed of light, you could even travel at "99.9 followed by a trillion trillion 9s"% of the speed of light but never quite 100%.According to our current mathematical theories, for an object with any mass to travel at the speed of light it would take infinite energy to attain that speed.
