bombarding the earth. and the source, they believe, is giant black holes in orbit around each other, all across space. these are at the heart of distant galaxies orbiting each other. the forces between them are so powerful that they distort time and space and send ripples of gravitational waves across the universe. the lovell telescope is among a network of observatories that have picked up these gravitational waves. astronomers want to use them to study the black holes. currently, the signal that we re seeing is a noisy background from all over space. it s a bit like being in a noisy restaurant with people talking all around you. what we hope is that in the near future, we ll be able to zoom in and listen to some individual conversations, take the measurements from individual black holes and be able to really zoom in and study them. the researchers now have a new way to study the cosmos. they hope to learn how galaxies formed and discover
The existence of gravitational waves was predicted by Albert Einstein’s general theory of relativity more than a century ago, but its experimental confirmation came only in 2015.
new things that may reveal how the universe first came into existence. pallab ghosh, bbc news, at the lovell telescope at jodrell bank. that s all for now stay with bbc news. hello there. at the moment, the weather seems to be changing quite a lot, really from one day to the next. on thursday, we were in cooler, fresher air with some sunshine, a few showers for northern parts of the uk. but on friday the weather s going to look and feel quite different. there ll be a lot of cloud heading our way. it s going to be bringing a bit of rain and drizzle and it will feel more humid as well. and we ve seen that cloud beginning to push in on a westerly breeze coming in from the atlantic
