Basically, we don't know what happened in our Universe, before the so-called age of the Universe was about one Plank time. Thus, that's as close to "the beginning" as we can currently theorize.At that time, what is now the OBSERVABLE Universe occupied much less space than a proton occupies nowadays; however, the entire Universe may have been much larger.
The big bang was the BEGINNING of the universe so there was no temperature before it :P
The event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
No, the Big Bang was not an explosion in the traditional sense. It was a rapid expansion of space and time that marked the beginning of the universe as we know it.
At the time universe started: time ZERO, big bang, beginning of the existence of energy and mater.
Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?
The matter present in the Universe began to become more and more dense and this huge density originates the big bang. That was the beginning of the Universe.
None. Theoretical physicists work on questions like the beginning of the universe, the possible end of the universe, and the Big Bang Theory.
The big bang theory explain the creation of everything. It gives the explanation of beginning of our universe and it's evolution
The Big Bang theory is the prevailing explanation for the beginning of the universe. It posits that the universe began as a singularity around 13.8 billion years ago and has been expanding ever since. This theory is supported by evidence such as the cosmic microwave background radiation and the observed redshift of galaxies.
The heat left over from the beginning of the universe is known as the cosmic microwave background radiation. It is a faint glow of radiation that permeates the entire universe and is a remnant of the Big Bang. This radiation provides important clues about the early universe and the formation of galaxies.
The big bang or God created it. Mostly the big bang is the scientific reason and God is the religious reason.
The Big Bounce theory suggests that the universe expands and contracts in a continuous cycle, with each cycle ending in a "big crunch" followed by a new "big bang." This theory is an alternative to the Big Bang theory and proposes that the universe has no beginning or end.
