In our current understanding of the universe based on the principles of Einstein's theory of relativity, everything in the universe, including matter, energy, and information, must travel at or below the speed of light in a vacuum (denoted as 'c'). The speed of light in a vacuum is approximately 299,792,458 meters per second (or about 186,282 miles per second).
According to the theory of relativity, the speed of light is considered to be an absolute cosmic speed limit. Any object with mass that has "rest mass" (meaning it is not massless like a photon) would require an infinite amount of energy to accelerate it to the speed of light, which is practically impossible. As an object with mass approaches the speed of light, its mass would increase, and it would require more and more energy to accelerate further.
Therefore, for anything with mass, it's impossible to reach or exceed the speed of light. However, objects with massless particles, like photons (particles of light), always travel at the speed of light in a vacuum.
Keep in mind that while this is our current understanding based on extensive experimental evidence and observations, our understanding of the universe may evolve as scientific discoveries and advancements occur.
