The Big Bang

Most astronomers believe that the universe began in the Big Bang about 14 billion years ago. Back then, the entire universe was in the bubble several thousand times smaller than the needle. It's hotter and denser than what we think.

Then it burst out suddenly. The universe we know is born. Time, space and problems began with big bangs. Within less than a second the universe evolved from less than 1 atom to greater than the galaxy. It continues to grow at an amazing rate. Today is still expanding

As the universe expands and cools, energy becomes particles and antimatter of matter. The particles of these two opposite types largely destroy each other. But some things survived. When the universe is 1 second, the more stable particles are called protons and neutrons.

In the next 3 minutes, the temperature fell below 1 billion degrees. It is now cool enough for protons and neutrons to form nuclei of hydrogen and helium together

After 300,000 years, the universe has cooled down to about 3,000 degrees. The nucleus can ultimately capture electrons and form atoms. The universe is full of hydrogen and helium

The time to the appearance of the big bang is pointless. If the Big Bang is the beginning of time, there is no universe in front of the Big Bang. Without time, there is no "front". Other ideas suggest that the Big Bang was not the beginning of 13.8 billion years ago. On the contrary, some people think that there is a completely different universe before the Big Bang, but that may be very different from what we know today.

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)

They can not say anything about the exact moment of the Big Bang. I can not explain the exact moment of the big bang, what happened before, or the cause of the big bang. Cosmologists have many ideas about this, but to be frank, there is no real evidence. Therefore, when explaining the cause of the Big Bang and the moment when the universe caused something, the Big Bang cosmology can not do better than the story of traditional origins. But from that moment they can talk about logical, evidence-based, very good.
