What events happened after the Big Bang?

As space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos.

What was the order of the Big Bang?

A summary of the Big Bang events occurred in this order: Planck Era ; initial energy → Elementary Particles – photons create particles and antiparticles → Inflation of the Universe → Four Forces become distinct (strong, weak, electromagnetic, and gravity) →

What happened 20 minutes after the Big Bang?

After about 20 minutes, the temperature and density of the universe has fallen to the point where nuclear fusion cannot continue.

What is the timeline of the Big Bang theory?

In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago. At this time, all matter was compacted into a very small ball with infinite density and intense heat called a Singularity.

Why was the second stage of the Big Bang so quick?

The second stage of the Big Bang was so quick that it was 100 times faster than a second! Now that’s quick! Basically, all the energy and heat from the explosion shot out. And wherever it travelled created space. This space created by the particles from the explosion is what we call the universe today.

How many stages are there in the Big Bang?

Well, since you asked, the Big Bang has four main stages. The first actually begins before it happened!

How long has the universe been around since the Big Bang?

Since the Big Bang, 13.7 billion years ago, the universe has passed through many different phases or epochs. Due to the extreme conditions and the violence of its very early stages, it arguably saw more activity and change during the first second than in all the billions of years since.

How did the explosion of the Big Bang happen?

Big Bang is a massive explosion happened, since 15000 million years, resulting in it all the forms of matter, energy and time, It is the expansion of the universe and merging of atomic particles forming helium and hydrogen gases. How did the universe originate?
