THE SPEED OF UNIVERSE
THE SPEED OF UNIVERSE The speed of light in a vacuum It's not just the fastest known speed that a particle can reach, but it also acts as an effective speed limit for the rest of the universe. Light speed is nearly 300,000 km/sec, which is the equivalent of travelling seven and a half times around the Earth in a single second.So that the supposedly " UNBREAKABLE" speed, next we need to consider Einstein's theory of general relativity. It states that if an object ever reaches the speed of light, it will have infinite mass and zero length.It is impossible. In 2012, a team at " CERN" claimed to have measured neutrino particles travelling 0.002% faster than sp. light..... But it turned out that a loose fibrous cable had skewed the measurements. More recently, and marginally more successfully, a 2017 theory suggested that there might be another particle, called a tachyon, that really could travel faster than the speed of light, but it's a virtual particle ex
