Earth formation,
00:04 - 00:06
a spinning this of gas and dust
00:06 - 00:07
billions of years ago,
00:07 - 00:09
Earth and the rest of the solar system existed
00:09 - 00:12
only as an enormous cloud of dust and gas.
00:12 - 00:16
Eventually something happened to create a disturbance in that dust cloud,
00:17 - 00:21
setting forth a chain of events that would lead to the formation of life as we know it.
00:24 - 00:28
One common hypothesis among scientists is that a distant star collapsed,
00:28 - 00:30
creating a supernova explosion,
00:30 - 00:34
which disrupted the dust cloud and caused it to put together this form,
00:34 - 00:39
this form that's spinning disk of gas and dust, known as the solar nebula.
00:39 - 00:41
The faster the clouds spun,
00:41 - 00:45
the more the dust and gas became concentrated at the center,
00:45 - 00:48
further fueling the speed of the nebula.
