Can anything travel faster than the speed of light? 'Lightning' seen sparking from a supermassive black hole appears to break the laws of physics
Article from the website dailymail.co.uk.
According to the laws of physics, the speed of light is a fundamental barrier that cannot be broken - nothing is supposed to be able to travel faster than it.
So astronomers were left baffled when they spotted powerful flashes of energy bursting out from the heart of a supermassive black hole at the centre of a galaxy 260 million light years from Earth.
Measurements of this gamma ray 'lightning' showed it was travelling across the event horizon - the boundary where nothing can escape the intense gravity of the black hole - at rates that appeared to be faster than the speed of light.
