According to our current understanding of physics, no material or substance can survive traveling at the speed of light (often denoted as "lightspeed" or "c").
The theory of relativity, proposed by Albert Einstein, states that as an object with mass approaches the speed of light, its mass would become infinite. This would require an infinite amount of energy to propel it, which is not achievable in practice. Moreover, as an object approaches the speed of light, its length would contract and time would dilate according to the theory of special relativity. These effects make it impossible for an object with mass to reach or exceed the speed of light.
Therefore, there is no known material or substance that can withstand or survive traveling at the speed of light.
