Did space and time exist before the Big Bang?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Did time start with the Big Bang?
The general view of physicists is that time started at a specific point about 13.8 billion years ago with the Big Bang, when the entire universe suddenly expanded out of an infinitely hot, infinitely dense singularity, a point where the laws of physics as we understand them simply break down.
Was time created before the Big Bang?
For 13.8 billion years, the universe has been expanding, cooling and evolving. Textbooks often say that the start of this expansion — the Big Bang — was the start of time. “Others don’t use the inflationary mechanism but still have a phase which is before the Big Bang — before the conventional expanding phase.”
What came first space or time?
According to Albert Einstein, space and time are simply different aspects of the same entity now called ‘spacetime’. It therefore seems plausible that they came into existence simultaneously.
What existed before space?
The Universe has not existed forever. It was born. Around 13.82 billion years ago, matter, energy, space – and time – erupted into being in a fireball called the Big Bang. It expanded and, from the cooling debris, there congealed galaxies – islands of stars of which our Milky Way is one among about two trillion.
Did the Big Bang create space and time?
Opinions expressed by Forbes Contributors are their own. This article is more than 3 years old. The Big Bang created space and time. Before that, there was no space.
How can you tell what happened before the Big Bang?
If there was a big bang where space-time was created, you cannot tell what was before. Time was created in that instance and there is no way to tell what was before. You can only tell one event happened before another event if they both happen in the same space-time. There is no “before the big bang”.
Who invented time in the universe?
Time has been invented by man. However, we can replace the time indicator of Universe dynamic by the matter density. In some sense the density correlates with time. Therefore, we can assume that in the beginning the density was equal to zero (no matter existed), and the singularity problem disappears.
Does time exist outside of our universe?
Similarly, time, far from being eternal, is just a property of our universe. It is possible to construct hypothetical universes that are logical and self-consistent, with no time at all, or with more than one time. So outside of our universe, time has no meaning. “Before the Big Bang” would be, by definition, outside of our universe.
