:00:00. > :00:09.Meantime, don't forget to head over to the website to let us know your
:00:10. > :00:11.predictions for the weekend. -- on this week's Kickabout.
:00:12. > :00:13.Good morning - it's Friday and I'm Hayley,
:00:14. > :00:17.We've got loads for you, so let's get going.
:00:18. > :00:19.The boy who beat Everton players to the post gets his Goal
:00:20. > :00:30.First to an incredible discovery by scientists that will help us
:00:31. > :00:36.Because of the force of gravity, if you drop something,
:00:37. > :00:38.it falls down to the ground instead of up.
:00:39. > :00:41.Now for around 100 years, scientists have had ideas about how
:00:42. > :00:46.gravity might change in space and create ripples just like waves.
:00:47. > :00:51.Now, an international team has been able to prove that those
:00:52. > :01:01.theories are true. Leah has got this one.
:01:02. > :01:07.Black holes, the strangest objects in the universe. They cannot be
:01:08. > :01:11.seen, but scientists know they are there because of the way they move
:01:12. > :01:14.things around them. Now, group of researchers think they have made one
:01:15. > :01:22.of the biggest discoveries in 100 years. In a galaxy far, far away,
:01:23. > :01:27.two black holes smashed together more than a billion years ago. It is
:01:28. > :01:34.only now that the shock waves have reached earth. When you consider
:01:35. > :01:37.that these black holes spiralled in more than a billion years ago, and
:01:38. > :01:43.the signal has been travelling to us since then, and we turned on our
:01:44. > :01:49.detect is at just the right time to detect it arriving... This is a
:01:50. > :01:54.model of what the scientists found. First, two black holes spin towards
:01:55. > :01:58.each other, giving off waves of gravity, which is a force which
:01:59. > :02:02.attracts things towards each other. These waves get stronger and
:02:03. > :02:07.stronger until the black holes eventually collide. Professor
:02:08. > :02:13.Stephen Hawking is one of the world's most famous experts on black
:02:14. > :02:18.holes. He says the discovery has a special moment in the history of
:02:19. > :02:24.science. Gravitational waves provide a completely new way of looking at
:02:25. > :02:28.the universe. The ability to detect them has the potential to
:02:29. > :02:34.revolutionise astronomy. But why is it so important? By scanning the
:02:35. > :02:38.skies, astronomers can use these waves of gravity to find black
:02:39. > :02:43.holes, things which have been completely invisible to telescopes
:02:44. > :02:45.until now. Scientists hope this will open up parts of the universe which
:02:46. > :02:49.have never been known about before. Tech experts in Switzerland have
:02:50. > :02:51.taught drones to find their way through forests to help find lost
:02:52. > :02:53.or injured walkers. Researchers think that roughly 1,000
:02:54. > :02:56.people make emergency calls for help from forests and mountains
:02:57. > :02:58.in Switzerland alone. With this new ability to follow
:02:59. > :03:00.man-made trails in forests, drones will be able to help
:03:01. > :03:04.in search and rescue missions. It is hoped they will help teams
:03:05. > :03:08.to get to injured To football now, and it has been
:03:09. > :03:13.a funny old season in the Premier League,
:03:14. > :03:15.with lots of the big clubs like Chelsea and Manchester United
:03:16. > :03:17.struggling. And Leicester City are
:03:18. > :03:19.currently top of the table. Make sure you're watching at 8.15,
:03:20. > :03:22.because Martin has been finding out why they have been doing
:03:23. > :03:36.so well this season. Leicester City have done so well
:03:37. > :03:39.because they have got the police, the confidence, they have had a
:03:40. > :03:43.wonderful string of results, and they have got a team with some
:03:44. > :03:48.superstars like Jamie Vardy and Riyad Mahrez, but they have also got
:03:49. > :03:52.everyone else who is producing as best they possibly can, players like
:03:53. > :03:55.Danny Drinkwater and Kasper Schmeichel. Their defence has been
:03:56. > :03:59.brilliant, and they are scoring goals as well. They have been the
:04:00. > :04:01.surprise of the season. Every neutral would love to see them win
:04:02. > :04:03.the league this season. Earlier in the week,
:04:04. > :04:06.we told you about nine-year-old George, who won the Goal
:04:07. > :04:09.of the Month competition at Everton - beating the club's big stars
:04:10. > :04:12.like Ross Barkley and Aaron Lennon. Well, George has picked
:04:13. > :04:14.up his trophy from Everton manager And he got the chance to meet some
:04:15. > :04:19.of the Everton team, too. Hundreds of manatees are heading
:04:20. > :04:24.to warm waters in the US to help them survive the freezing
:04:25. > :04:27.winter weather. The big mammals can suffer from cold
:04:28. > :04:30.stress when water temperature drops below 20 degrees Celsius,
:04:31. > :04:33.causing them to lose weight But more than 300 manatees have
:04:34. > :04:41.crowded together under water at Three Sisters Springs in Florida,
:04:42. > :04:45.where they will be much more comfortable as they wait
:04:46. > :04:50.for winter to pass. Newsround is back right
:04:51. > :04:55.here in about half an hour.
