That's already been done. Light, radio, X-rays and other stuff all travel at light
speed every day. I hope this news brings you reassurance and relief.
Light speed is over one billion kilometers per hour. Not only can a human not run that fast, no spaceship can ever travel that fast, at least according to the laws of physics as we currently understand them.
No human has flown faster than the speed of light, as it is currently considered impossible based on our understanding of physics. The speed of light, approximately 299,792 kilometers per second, is the cosmic speed limit according to the theory of relativity.
Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
Nothing has ever gone faster than the speed of light.
Nothing has ever been manufactured that could move anywhwere near the speed of light, and according to the best current science, nothing in nature can ever move faster than the speed of light.
The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.
The same as it ever was-The Speed of Light
The speed of light is different in different substances ... air, water, glass, jello, etc.
Nothing can travel at the speed of light, only light itself, the closest we have ever gotten to the speed of light is 99.9 %, we have accelerated particles at very very close to the speed of light using the LHC (Large Hadron Collider). The only thing that can go faster than the speed of light, is Space.
It is currently not possible to travel at the speed of light according to our current understanding of physics. Developing technology to allow for light speed travel would require major breakthroughs in propulsion systems, energy sources, and materials. While advancements continue to be made in space exploration, it is uncertain if such technology will be achievable in our lifetime.
I'm afraid nothing happens to the speed of light ever. Also "air" is consider'd a gas.
Tachyon is the fastest thing ever because its slowest velocity is the speed of light! Light is the fastest thing that can be seen.
