The speed of light, exactly 299,792.458 meters per second in a vacuum, is something unattainable by humans, at least for now, because if that speed is equalized, the laws of physics they would have no sustenance in it.

What is the speed of light?
The speed of light is an indispensable measurement tool for astronomy and physics, since knowing it has brought new knowledge about the vast universe.
And the importance of having determined the speed of light is such that it determined that the measurement in meters or kilometers becomes obsolete in space.
However, it is necessary to highlight that the speed of light falls short in comparison to the immensity of space. A clear example is the closest star to Earth, Alpha Centauri, which is just over 4 light years away.
Another example that highlights the great distances of space is that the speed of light would take around 100,000 years to travel through the Milky Way.
What would happen if you traveled at the speed of light?
At the speed of light, time and space would be distorted.which would cause a person who moves at that speed not to age in the same way as someone who moves normally does.
What would it look like to travel around the Earth at the speed of light?
The YouTube channel CdeCienciawhich as its name indicates, is dedicated to scientific issues, shared a video showing what it would look like to go around the world at the speed of light.
