The Big Bang Theory is a theory of the evolution of the universe since one time after the singularity. The singularity is what you are referring to and the Big Bang Theory is silent about what that was and how it might have come about.Quds Akbar said:Did space time be created at the Big Bang, if it did, then theoretically, gravity would not be a fundamental force associated with the Big Bang and any events before the Big Bang would be undefined?
What do you mean by "the singularity", I have recently realized that if the Universe is infinite then it must have always been, so what is "the singularity"?phinds said:The Big Bang Theory is a theory of the evolution of the universe since one time after the singularity.

If the extrapolate the math backwards you find that at what is called "t=0" or "the singularity" is the place where the model blows up and gives unphysical answers. That's the basis for the "one Plank Time later" on which the Big Bang Theory is based.Quds Akbar said:What do you mean by "the singularity", I have recently realized that if the Universe is infinite then it must have always been, so what is "the singularity"?
According to the Big Bang theory, space and time were created simultaneously during the event known as the Big Bang. Before the Big Bang, there was no concept of space or time as we know it. The universe was a singularity, a point of infinite density and temperature, and the laws of physics as we know them did not exist.
There are several pieces of evidence that support the idea that space and time were created at the Big Bang. One of the most significant is the cosmic microwave background radiation, which is a remnant of the intense heat and light that filled the early universe. This radiation is consistent with the predictions of the Big Bang theory and is considered a strong piece of evidence for the theory.
The answer to this question is still a topic of debate among scientists. Some theories suggest that there may have been a pre-Big Bang universe, but it would have been vastly different from the universe we know today. Others argue that the concept of time does not exist before the Big Bang, so it is impossible for space time to have existed before then.
The expansion of the universe is closely tied to the creation of space and time at the Big Bang. As the universe expands, space and time expand with it. This expansion is thought to have started during the Big Bang and has continued ever since. The expansion of space and time is also believed to be accelerating, driven by a mysterious force known as dark energy.
In the Big Bang theory, space and time are integral components of the universe. They are not separate entities, but rather interconnected aspects of the fabric of the universe. The theory suggests that before the Big Bang, there was no space or time, and the universe was compressed into a singularity. As the universe expanded, space and time were created and continue to evolve with the expansion of the universe.
