What is the Big Bang?

In 1927, an astronomer named Georges Lemaître had great ideas. He used to say that the universe was only the first point long ago. He said the universe stretched to its current size and expanded, and it could continue to grow

The universe is a very wide place, it has existed for a long time. It is difficult to imagine how to start everything

Two years later, an astronomer named Edwin Hubble noticed that other galaxies are moving away from us. And that's not all. The farthest galaxy moves faster than our galaxy

As Lemaître thinks, this means that the universe is still expanding. If things are falling apart, it means long ago that everything got together.

Everything we can see today in space today - stars, planets, comets, asteroids - they did not initially exist. Where are you from.

When the universe begins it is just a hot small particle that blends light and energy. This is quite different from what we are seeing now. As it expands and occupies more space, it gradually cools down.

Small particles are gathered. They formed atoms. Then those atoms are grouped together. In many cases, atoms together form stars and galaxies.

The first star produces a group of atoms called larger atoms and molecules. This led to the birth of more stars. At the same time, the galaxy has collapsed together. Along with the birth and death of new stars, asteroids, comets, planets and black holes were formed!

How long does it take? Okay, the universe is 13.8 billion years ago, 13.8 billion years ago. It's a long time

This is the beginning of the universe. As it gets bigger and leads to such wonderful things, some people call it "Big Bang". But a better name would be "Everywhere Stretch". What do you think?

What is Big Bang theory? Big Bang theory is to explain what happened at the beginning of the universe. We point out that the earth was made by the explosion of a fireball. - Syria has experienced a civil war. A civil war is a war with the same country in that country. Stephen Starr said the civil war is under the reign of two million Syrian Christians under Sunni Muslim anti-government forces and Bashar al-Assad. Bashar al-Assad is president of Syria, he is frankly saying he is not a bad person, I believe that the government makes it a citizen to be afraid. The civil war is mainly because Christians do not gain the religious freedom they desire.

A statement by Steven Hawking, that time began in the Big Bang, and it would be ridiculous if the word "time" is commonly used. What happened before the Big Bang? Obviously, the big bang is an event someday. If this event is the beginning of time, then there must be another time, time of events. In fact, since Hawking uses the term "time" in the physical sense, this is not a real problem. As mentioned above, the physical concept of time exists in the theoretical system of the actual physical paradigm and can not be the same as the general concept (otherwise the physical theory can be refuted by logical means ). - The doctor will be forced to explain their theory to non-doctors and to link their technical terms to a common language concept that seems to be similar for this purpose (I think)
