The concept of time "before" the Big Bang is currently not well-understood by scientists and is still a topic of ongoing research and debate.

The Big Bang theory describes the origin of the universe as a singularity, a point of infinite density and temperature, that expanded and cooled rapidly, giving rise to the observable universe. However, the laws of physics as we know them today break down at the singularity, and our current understanding of the universe only extends back to a few fractions of a second after the Big Bang.

There are various speculative theories and hypotheses about what may have happened before the Big Bang, but they are mostly speculative and not yet supported by strong evidence. Some of these theories suggest that our universe may have emerged from a previous universe, or that the Big Bang was the result of a collision between multiple universes in a higher-dimensional space.

Overall, the question of what happened before the Big Bang remains one of the most challenging and unresolved questions in modern cosmology.

What did space look like before the big bang?

There was no such thing as 'space' before the Big Bang. In fact, there was no such thing as 'before' before the Big Bang. Space and time both began with that event.


How was the bigbang developed?

No one really knows. Development would involve time and there was no time before the Big Bang. No one knows what was there before the Big Bang. If the question is "What did the Big Bang develop into?" the answer would be the universe.


What was speed of matter at time of big bang?

According to our current understanding of physics, there was nothing "before" the big bang; not even time or space, so the notion of "before" is probably meaningless. We cannot imagine the conditions at the time of the big bang.


What exsited before big bang?

It is not currently known what happened before - or whether there even was a "before". Some say that time itself started with the Big Bang.


What was inside the space before big bang?

The concept of "before" the Big Bang is not well-defined as time as we know it began with the Big Bang itself. It is thought that the entire universe was in a hot, dense state at the moment of the Big Bang, with all matter and energy concentrated in a singularity.


Did other big bangs happened before?

There's no way to know, and at the present time, there is no theory, hypothesis, suggestion, or conjecture that describes anything before the big bang. In fact, according to current thinking in Physics and Cosmology, the big bang was the origin of "time", so the very concept of "before" the big bang has no meaning.


Which events occurs earliest in time?

The Big Bang! Space-time did not exist before the Big Bang so there can be no earlier events.


Did space time energy preexist the BIG BANG?

The concept of space-time energy as we understand it today began with the Big Bang, as the universe itself began to expand and evolve. Before the Big Bang, our current laws of physics cannot accurately describe what existed or how it behaved. The origin of space-time and energy remains a subject of speculation and ongoing scientific exploration.


What was it like before the big bang?

Before the Big Bang, according to current scientific understanding, there was no space, time, or matter as we know it. The concept of "before" the Big Bang is difficult to grasp because time itself is thought to have begun with the Big Bang. Some theories suggest that the universe existed in a state of singularity, a point of infinite density and temperature, before rapidly expanding in the Big Bang event. However, our understanding of this period is limited, and it remains a subject of ongoing research and theoretical exploration in the fields of cosmology and theoretical physics.


What do most scientists believe existed before the incident known as big bang?

Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.


When the big bang happened were humans alive?

No. The big bang was before the dinos.


What went on before the big bang?

The big bang hypothesis is just that, a hypothesis, and a hypothesis based on an extrapolation of an explanation of a Doppler frequency shift that is itself an unable to be proved hypothesis. So asking what went on before the big bang is meaningless and of course unanswerable. Consider this: The expressions, before and after imply the measure of time. Time did not exist before the BB, therefore the question is nonsensical. We can only spreak of 'after' the BB. Not before! Setting aside the issue of evolution and looking just at the Big Bang, the Big Bang created both space and time. It created the fabric we call spacetime in modern physics. It's not like the Big Bang happened in an "empty universe" that was here already with time passing in the void. No, the Big Bang actually "created the space" in which it now expands. And it created the time, too. These ideas are consequences of the Big Bang theory, and it is currently the best scientific way we have to explain the universe, explain how it formed and became what we can see all around us.
