You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
the true answer is light speed
Electromagnetic waves, such as light, travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (186,282 miles per second). This speed is constant and represents the maximum speed at which information or energy can travel in the universe.
Radio waves travel at the speed of light in a vacuum, which is about 299,792 kilometers per second (186,282 miles per second). This means that radio messages travel through space at the same speed. It takes about 1.3 seconds for a radio message to travel from Earth to the Moon, and about 4.3 years to reach the closest star system to our solar system.
Theoretically, it is possible to travel through time: by travelling at a great speed. But the speed at which you would have to travel would be faster than the speed of light, and would therefore kill every known living being.
To travel at the speed of light, you would need to have an infinite amount of energy, which is currently not possible with our current technology and understanding of physics. Additionally, as per the theory of relativity, an object with mass cannot reach the speed of light.
Seismic waves generally speed up as they travel downward and reach the Moho, the boundary between the Earth's crust and mantle. This increase in speed is due to the change in density and composition of the Earth's layers, causing the waves to travel faster in the more rigid mantle layer compared to the crust.
Neither, mass can never reach the speed of light, this question also contridicts the theory of realativity.
No, light does not travel at the same speed through all transparent media. The speed of light can vary depending on the medium it is traveling through. It typically travels slower through materials like glass or water compared to its speed in a vacuum.
Well, tachyons have not been proved real yet. If they were real maybe one day we can possibly travel through time or used their speed of 20 times the speed of light to reach far places the universe and beyond.
They travel through space at the same speed that Saturn travels.
Electrons are able to travel close to speed of light.
