Did the basic laws of physics also evolve after BB?

In summary, the conversation discusses the possibility of the laws of physics evolving right after the big bang and the potential for these laws to change in the future. It is noted that constants such as Planck's constant, the speed of light, and the gravitational constant are fundamental and will likely not change, but the properties of space and time may change.

Just thinking about this and I will say I do not know anything about cosmology or physics beyond what is common, but my question is, could the laws of physics, specifically how particles interact/behave, have evolved right after the big bang so that it started out with a simpler set of laws and then like planets and galaxies get created, fundamental particles and laws also get created? Were all the quantum laws (or other areas of science related to this) established immediately upon creation of the universe?
In a similar vein to this, is it possible that these laws can change in the future due to either their own internal workings or a macroscopic event that will affect them somehow? One example would be if photons, electrons, protons and other particles had the exact same structure and behavior and if they will always stay the same, but can apply to really anything that existed since the big bang.

What we must understand that h(Planck's constant), c(speed of light), G(gravitational constant) are fundamental constant's.The laws regarding them are one of the most fundamental and they determine everything.Unless new theoretical constraint's are found laws of universe will not change so easily.Quantum Laws will not change.What can change is space, time and their properties.Because these are things which we do not know much.

Related to Did the basic laws of physics also evolve after BB?

1. Did the basic laws of physics exist before the Big Bang?

This is a highly debated question among scientists. Some theories suggest that the laws of physics, such as gravity and electromagnetism, have always existed and were not affected by the Big Bang. However, other theories propose that the laws of physics did not exist until the Big Bang occurred.

2. How do we know that the laws of physics evolved after the Big Bang?

Scientists have observed the expansion of the universe and have been able to calculate the rate at which it is expanding. This rate is consistent with the laws of physics that we know today. Additionally, experiments and observations, such as the cosmic microwave background radiation, support the idea that the laws of physics have evolved since the Big Bang.

3. What evidence supports the idea that the laws of physics were different in the early universe?

One major piece of evidence is the abundance of light elements, such as hydrogen and helium, in the universe. These elements were formed shortly after the Big Bang and could not have been created without the laws of physics being different than they are now. Additionally, the cosmic microwave background radiation also provides evidence of a different early universe with different physical laws.

4. How could the laws of physics have changed after the Big Bang?

Some theories propose that the basic laws of physics were unified in the early universe and then gradually separated as the universe expanded and cooled. This process is known as symmetry breaking. Other theories suggest that the laws of physics may have changed due to the effects of gravity, quantum mechanics, or other unknown forces.

5. Can the laws of physics continue to evolve in the future?

It is possible that the laws of physics could continue to evolve in the future. Some theories suggest that the expansion of the universe could cause a gradual change in the laws of physics. However, this is still a topic of ongoing research and debate among scientists.
