Those experiments seek to answer some of the biggest questions in science. These include learning how the Universe began and how it will end, finding the first ever signs of life on planets orbiting distant stars, detecting black holes that ripple space time, mapping newborn planets around distant stars and analysing their atmospheres for signs of life. All of these are experiments in which, historically, the UK played a leading role. But now, British scientists could be largely locked out of them in the future, if the STFC does not pay its way.
