The cosmic speed limit nothing can travel faster than 300,000 kilometers per second

 The cosmic speed limit



Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). only mass less particles, including photons, which make up light, can at that speed. it's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.

The speed of light is widely known to be the absolute pinnacle of movement. When Albert Einstein first entwined mass and energy in his Theory of Relativity, it basically established the Universe’s speed limit at 299,792 kilometers per second (186,282 miles per second).

According to Einstein, nothing in the Universe that has mass could either match, or move faster than, light.

But that doesn’t mean that nothing can move faster than light. In truth, physicists have discovered a number of phenomena that have the ability to match, and actually beat (in specific respects), the speed of light. And there are several theoretical models that posit specific ways that the speed of light could be surpassed.

To be clear, these things don’t prove General Relativity wrong (at all). But they do help reveal just how complex our universe really is, and they show that very few things in physics can really be boiled down to one simple phrase.
