The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang. The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time in the history of our universe..
What was before the universe?
The universe materialized literally out of nothing, at a tiny but finite size, and expanded thereafter. There were no moments before the moment of smallest size because there was no “before.” Likewise, there was no “creation” of the universe, since that concept implies action in time..
What was the beginning of space and time?
Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down..
When did time and space begin?
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began. But what caused this explosion in the first place is still a mystery..
Which 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..
Another suggested theory is Eternal Chaotic Inflation took place before the singularity and the random noise leads to spacetime being filled with singularities. Singularities took place in everywhere through the space and after the big bang, early universe went through Cosmic Inflation and rapidly expanded.
Scientists once thought that space and time were separate, and that the universe was merely an assortment of cosmic bodies arranged in three dimensions. Einstein, however, introduced the concept of time as the fourth dimension, which meant that space and time were inextricably linked.
space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein's special theory of relativity (1905). (Read Einstein's 1926 Britannica essay on space-time.)

Mar 21, 2015The going theory is that space and time were created at the same “time”. In fact, space and time have been postulated to be a single entity called space-time.Was there an existence of space-time before the Big Bang? - QuoraWhen did time really begin? Did time begin before or after - QuoraWas space-time created by the Big Bang, or did it exist before? - QuoraThe Big Bang was the creation of space and time.

The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity — a point of infinite density and gravity — and that before this event, space and time did not exist (which means the Big Bang took place at no place and no time).
Can a space-time theory be equivalent to a quantum field theory?
Quantum field theory models have shown that it is possible for theories in two different space-time backgrounds, like AdS/CFT or T-duality, to be equivalent. According to Presentism, time is an ordering of various realities. At a certain time, some things exist and others do not.

Did time exist before the universe started to expand?
Put another way, time as we understand it literally did not exist before the universe started to expand. Rather, the arrow of time shrinks infinitely as the universe becomes smaller and smaller, never reaching a clear starting point.

Was a previous universe collapsing before the Big Bang?
January 22, 2018 at 2:55 pm The theory seems to ignore the possibility that, prior to the "big bang", a previous universe was collapsing into the singularity that became the genesis of the present universe. Some puzzling questions:How do we define space and time? .
,
Was time bent before the Big Bang?
According to TechTimes, Hawking says during the show that before the Big Bang, time was bent — "It was always reaching closer to nothing but didn't become nothing," according to the article. Essentially, "there was never a Big Bang that produced something from nothing. It just seemed that way from mankind's point of perspective." .

Sam & Max Beyond Time and Space
2007-2008 episodic video game
Sam & Max Beyond Time and Space, originally released as Sam & Max: Season Two, is an episodic graphic adventure video game by Telltale Games based on the Sam & Max comic book series created by Steve Purcell. It is a sequel to Telltale's previous Sam & Max game, Sam & Max Save the World, and was originally released as five episodes for Microsoft Windows over the course of late 2007 and early 2008, before being ported to other platforms in the following years. A remaster of the game by Skunkape Games was released in December 2021 for Windows, Nintendo Switch and Xbox One, and in September 2022 for PlayStation 4.

In condensed matter physics
Structure that repeats in time; a novel type or phase of non-equilibrium matter
In condensed matter physics, a time crystal is a quantum system of particles whose lowest-energy state is one in which the particles are in repetitive motion. The system cannot lose energy to the environment and come to rest because it is already in its quantum ground state. Because of this, the motion of the particles does not really represent kinetic energy like other motion; it has motion without energy. Time crystals were first proposed theoretically by Frank Wilczek in 2012 as a time-based analogue to common crystals – whereas the atoms in crystals are arranged periodically in space, the atoms in a time crystal are arranged periodically in both space and time. Several different groups have demonstrated matter with stable periodic evolution in systems that are periodically driven. In terms of practical use, time crystals may one day be used as quantum computer memory.
