Laws Before Big Bang or After Big Bang

In summary, before the Big Bang, the concept of time and space did not exist, and the laws of physics as we know them were not applicable. The cause of the Big Bang is still debated, with theories ranging from quantum fluctuations to a multiverse. Immediately after the Big Bang, the universe rapidly expanded and cooled down, allowing for the formation of particles and atoms. Currently, there is no scientific evidence or methods to study events before the Big Bang. However, some theories suggest that the fundamental laws of physics may have been the same before and after the Big Bang. This remains a topic of research and debate among scientists.

Interested in thoughts...
Did the laws of the universe exist before inflation phase of the 'big bang' allowing the 'big bang' to evolve, or did the laws evolve later...

I don't see how one could answer this question, since you need to make some assumption about laws in order to construct a model that makes predictions at all.
 

Related to Laws Before Big Bang or After Big Bang

1. What is the meaning of "Laws Before Big Bang or After Big Bang"?

The term "Laws Before Big Bang or After Big Bang" refers to the laws of physics that govern the universe before and after the Big Bang event. These laws determine the behavior of matter and energy in the universe and play a crucial role in the formation and evolution of the universe.

2. Was there a set of laws that existed before the Big Bang?

The concept of "before" the Big Bang is still a topic of debate among scientists. Some theories suggest that time did not exist before the Big Bang, so the question of laws existing before it may not be applicable. Other theories propose that the laws of physics, as we know them, may have been different before the Big Bang. However, there is currently no scientific evidence to support either of these ideas.

3. How were the laws of physics established after the Big Bang?

The laws of physics that we observe today were established in the first few moments after the Big Bang. During this time, the universe was incredibly hot and dense, and all the fundamental forces of nature were unified. As the universe expanded and cooled, these forces began to separate, leading to the development of the laws of physics that we know today.

4. Can the laws of physics change after the Big Bang?

The laws of physics are considered to be fundamental and unchanging, but there are some theories that suggest they may have changed in the early stages of the universe. For example, the theory of inflation proposes that the universe underwent a rapid expansion in the first fractions of a second after the Big Bang, during which the laws of physics may have been different. However, this is still a topic of ongoing research and has not been conclusively proven.

5. How do the laws of physics affect the formation and evolution of the universe?

The laws of physics play a crucial role in the formation and evolution of the universe. They determine the behavior of matter and energy, which, in turn, affects the formation of galaxies, stars, and planets. The laws of gravity, for example, dictate how matter clumps together to form larger structures, while the laws of thermodynamics govern the transfer of energy within the universe. Without these laws, the universe as we know it would not exist.
