Did researchers at CERN break the speed of light?
Scientists said on Thursday they recorded particles travelling faster than light – a finding that could overturn one of Einstein’s fundamental laws of the universe.

Who broke the speed of light?
The gist is that scientists at CERN laboratory fired 15,000 beams of neutrinos – tiny particles that pervade the cosmos – over a period of three years and many were recorded travelling faster than the speed of light…
Will we ever break the speed of light?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

How did they first measure the speed of light?
In 1638, Galileo is often credited with being the first scientist to try to determine the speed of light. His method was quite simple. He and an assistant each had lamps which could be covered and uncovered at will. Galileo would uncover his lamp, and as soon as his assistant saw the light he would uncover his.
How do you calculate the speed of light?
Find the distance in terms of light using the formula: dL = ct. Where c is the speed of light, dL is the distance, and t is the time period. For a light year: Light year = speed of light × number of seconds in a year. Cosmological distances can be found using a cosmological calculator and the redshift of the object in question.
How the speed of light was first measured?
The first measurement of the speed of light in a laboratory was by Hippolyte Armand Fizeau (1819-1896) in 1849.
How do people measure the speed of light?
The speed of light in a vacuum stands at “exactly 299,792,458 metres per second“. The reason today we can put an exact figure on it is because the speed of light in a vacuum is a universal constant that has been measured with lasers; and when an experiment involves lasers, it’s hard to argue with the results.
