00:00Imagine waking up one day to no internet, no TV, no phone calls.
00:04Sounds impossible, right?
00:06Well, it could become a reality,
00:08thanks to something called the Kessler syndrome.
00:11You might have seen this dramatic scene in the movie Gravity,
00:14but it's not just Hollywood fiction.
00:16Scientists believe this could actually happen.
00:19Here's the deal.
00:20Right now, over 10,000 satellites orbit Earth,
00:24and that's just the beginning.
00:26Add millions of pieces of space junk flying around,
00:28and you've got a serious problem.
00:31Collisions between this debris can trigger a domino effect,
00:34called the Kessler syndrome,
00:35that creates more and more debris.
00:38And if this spiral continues, it could knock out our satellites.
00:41No satellites means no Wi-Fi, no TV, no GPS,
00:45no weather updates, nothing.
00:47It would completely change life as we know it.
00:50But there's hope.
00:51Scientists are working on ways to clean up space,
00:54like recycling old satellites
00:56or safely burning them up in the atmosphere.
00:58If we act fast,
01:00we can stop the Kessler syndrome before it's too late.
01:02The question is, will we?
