00:00I am going to hold your hand when I say this.
00:01Even though we've only discovered just over 6,000 planets outside of our solar system,
00:07current estimates tell us that there are over 100 sextillion planets in the observable universe.
00:12That is a one followed by 23 zeros.
00:16To put that into perspective, if you split that number up by 8 billion people
00:20and gave each person 80 years to inspect all of their planets for life,
00:25each person would need to check 423 million planets per day.
00:30If we were able to check one planet for every second that has passed since the dinosaurs went extinct 66
00:36million years ago,
00:37we would have checked over 2 quadrillion planets, or about 0.002% of the total.
00:44There are about 100 planets for every liter of water here on Earth,
00:48and 92% of all of the planets that will ever exist haven't even formed yet.
