İzlediğiniz için teşekkür ederim.

We frequently hear about some discoveries of exoplanets like our Earth

00:13.000 --> 00:15.000
or of Earth twins.

00:15.000 --> 00:20.000
How common are Earth-like habitable planets in the universe?

00:20.000 --> 00:23.000
The short answer is we have no idea how common they are

00:23.000 --> 00:28.000
because it's at the edge of our technology to even detect an Earth-sized planet

00:28.000 --> 00:32.000
around a sun-like star with an Earth-like orbit.

00:32.000 --> 00:36.000
And so we're just at the edge of being able to detect planets like that.

00:36.000 --> 00:38.000
Even once we detect a planet like that,

00:38.000 --> 00:42.000
we don't have the technology to determine whether there's water on the planet or not.

00:42.000 --> 00:44.000
We can't tell whether there are continents.

00:44.000 --> 00:46.000
We don't know what its rotation rate is.

00:46.000 --> 00:52.000
And so we're just beginning to measure the very basic parameters

00:52.000 --> 00:54.000
of whether a planet is Earth-like.

00:54.000 --> 00:57.000
Does it have the same kind of orbit as the same size

00:57.000 --> 01:00.000
and does it orbit a star like the Sun?

01:00.000 --> 01:04.000
So that really doesn't answer the question of how common are Earth-twins.

01:04.000 --> 01:08.000
I suspect over the next 30 or so years we'll develop that technology.

01:08.000 --> 01:11.000
And I think what we're going to find is that there are going to be planets

01:11.000 --> 01:13.000
that look increasingly like Earth,

01:13.000 --> 01:17.000
but then it allows us to answer the real question we want is,

01:17.000 --> 01:18.000
is there life out there?

01:18.000 --> 01:20.000
And my suspicion is, my prediction is,

01:20.000 --> 01:24.000
what we will find is that we'll find planets that look increasingly like Earth,

01:24.000 --> 01:29.000
but there's going to be very little or no life on any of those planets

01:29.000 --> 01:33.000
until effectively you get something that looks almost exactly like Earth,

01:33.000 --> 01:37.000
and that's going to be a sign that God has created life somewhere else as well.

01:54.000 --> 02:04.000
And focus on thataments.

02:04.000 --> 02:09.000
So that we already might point out if we look forward in climate change.

02:09.000 --> 02:10.000
Then we też ok?

02:11.000 --> 02:14.000
So we'll have to figure the next 20 seconds.

02:14.000 --> 02:16.000
It's a weird kind ofік banget.

02:16.000 --> 02:18.000
So that we're going to look forward to it as a moment.
