How was the earth created after the Big Bang?

How was the earth created after the Big Bang?

About a billion years after the Big Bang, gravity caused these atoms to gather in huge clouds of gas, forming collections of stars known as galaxies. Gravity is the force that pulls any objects with mass towards one another — the same force, for example, that causes a ball thrown in the air to fall to the earth.

How long after the Big Bang did life on Earth form?

For comparison, the earliest evidence of life on Earth dates from 3.8 billion years ago, about 700 million years after our planet formed. A 2013 map of the background radiation left over from the Big Bang, taken by the ESA’s Planck spacecraft, captured the oldest light in the universe.

Did the Earth and the universe form at the same time?

According to standard scientific theory, the sun, earth, other planets and asteroids (from which we get meteorites) formed at roughly the same time, about 4.6 billion years ago, accreting under the force of gravity from a nebula.

Who formed the Earth?

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

How did the universe form in the Big Bang?

Thanks to a series of calculations, observations from telescopes on Earth and probes in space, our best explanation is this. Around 13.8 billion years ago, all the matter in the Universe emerged from a single, minute point, or singularity, in a violent burst.

How did life evolve after the Big Bang?

Earthlings may be extreme latecomers to a universe full of life, with alien microbes possibly teeming on exoplanets beginning just 15 million years after the Big Bang, new research suggests. Traditionally, astrobiologists keen on solving the mystery of the origin of life in the universe look for planets in habitable zones around stars.

What happens to space after the Big Bang?

Then this point started stretching outward in all directions, not expanding within space but causing the expansion of space itself. The first period of time immediately after the Big Bang is known as the Planck epoch, which occurred during the first 10 -43 seconds after it.

When was the Solar System born after the Big Bang?

A little after 9 billion years after the Big Bang, our solar system was born. The Big Bang. The Big Bang did not occur as an explosion in the usual way one think about such things, despite one might gather from its name.
