There was no space-time before the Big Bang, then how could quantum fluctuations give birth to the universe.

  • The `Quantum Universe` explains particle physics and a quantum leap in our understanding of the mystery and beauty of the universe.
  •  Quantum technology is widely considered the future, though it is still an emerging and developing field. While the full realization of its potential is likely decades away, significant global investment, ongoing research, and rapid advancements in areas like quantum computing, communication, and sensing point toward a future where these technologies will bring about transformative changes across many sectors, from drug discovery to finance and national security.

  • One of the objections with quantum theory is that it is inherently statistical in nature. In general, statistical theories are developed because there is insufficient information available about the system. This was a primary criticism of the theory by Einstein.

    The exact cause of the Big Bang is unknown and may be beyond the scope of current physics. However, the prevailing scientific model suggests that the universe began from an extremely hot, dense state that rapidly expanded in an event called cosmic inflation. When this inflationary period ended, the energy driving it was released, leading to the “reheating” of space and the formation of the first particles and energy, which is what we observe as the Big Bang. 
    Extreme Density and Heat:
  • . The universe started as a point of unimaginable heat and density, smaller than an atom. 
  • Expansion of Space:
  • The Big Bang was not an explosion in space but the expansion of space itself. 
  • Formation of Particles:
  •  The Trigger:
  • The specific trigger that initiated the Big Bang, or the process of inflation, is not fully understood. 
  • Before Time:
  • It is difficult to discuss what “caused” the Big Bang because time and space themselves are thought to have begun with the Big Bang, making the concept of “before” meaningless in our current understanding of physics. 
  • Quantum Physics:
  • Some theories suggest the cause might lie in quantum mechanics, where events can occur spontaneously and randomly without an obvious cause. 
Cosmic Inflation: A theory proposing a period of extremely rapid, accelerating expansion of space in the first fractions of a second after the universe began. 
Brane collisions:
Some speculative theories suggest that our universe might be a “brane” (a sheet of spacetime) and that the Big Bang could have been caused by the collision of two such branes.

The origin of the Big Bang can be answered using quantum physics, but that doesn’t mean you’re going to like the answer.
  • The universe could have been created by quantum fluctuations when there was no pre-existing space-time, which is one of the deepest mysteries in cosmology. The leading theoretical explanations do not assume fluctuations occurred “in” spacetime, but that the universe emerged from a state of “quantum nothingness” where fluctuations are more fundamental than space and time themselves. 
  • First… “before the Big Bang.” That expression implies that “the Big Bang” was an event. Granted, it is sometimes used to refer to the initial singularity predicted by general relativity, but in cosmology books, you rarely see the phrase used in this manner. Far more often, you may see expressions like “the Big Bang paradigm.” This simply refers to the idea (strongly backed by observation) that in the distant past, the universe was hot and dense.
Closely related to this is the popular notion that the standard physical cosmology is akin to an alternate creation mythology: “It all started with a Big Bang,” says the song. No. Or maybe it did, maybe it didn’t, but cosmology, as I often stressed, is a science that begins with the present (when we make observations) and uses the known laws of physics to extrapolate back into the distant past, as far as we can, but no farther. No competent physicist will tell you how “it all started” because we do not know. We know with reasonable certainty what the universe was like when it was maybe a picosecond old. That in itself is a remarkable scientific achievement. But what happened in that first picosecond? Was it even a picosecond or an eternity? Nobody really knows. At best, we have informed speculation, nothing more. Now again, we take general relativity. If there was no space-time before the Big Bang, how could quantum fluctuations give birth to the universe? Allow me to address overly meticulous, though it’s far from it. The terminology used in such discussions can often be misrepresented in popular science literature, leading to misconceptions among readers.
  •  While it is sometimes utilized to refer to the initial singularity predicted by general relativity, in most cosmology literature, you will rarely encounter the term used in this manner. Instead, it is more common to read about concepts like “the Big Bang paradigm.” This term encapsulates the scientifically supported understanding that the universe was once in a state that was extremely hot and dense, rather than implying a definitive starting point in the traditional sense.
