Big Bang is a model of the universe which specially deals with the question that how the universe might have started.It mainly suggests that 13.798 billion years ago,all the matter in the universe was concentrated into a point of zero size,with infinite density,mass and spacetime curvature.The point suddenly exploded,releasing unimaginable amount of energy. The energy then might have transformed into mass, as particles could be created out of energy.During big bang,universe was infinitely hot.As the universe expanded, its temperature would have decreased to few million centigrades.At this temperature, the molecules lost their capability to overcome nuclear force,and would have started to form atoms and molecules.This process finally gave birth to several trillion molecules,which have been transferred evenly throughout the space available. By this process,the universe is thought to be originated.
Our concept of the "big bang" has no explanation about how or why, but our hypothesis is that there was NOTHING before the Big Bang created the universe.
Georges Lemaitre proposed a concept which later, became popularised as 'The Big Bang Theory'
The concept of the Big Bang is theoretical and without definitive origin. Consequently the concept of a Big Banger to initiate the Big Bang is less than theoretical.Theoretically, an unnamed instability is explained as the likely cause ofthe Big Bang. A small quantum fluctuation could have created all the matter and energy we see today and inflation accelerated that energy outward.
We have no idea what, if anything, existed before the Big Bang, or even if the concept of "before" has any meaning in this context.
No, the Big Bang was not an asteroid. The Big Bang theory is the scientific explanation for the origin of the universe, proposing that it began as a singularity and has been expanding ever since. An asteroid is a rocky object in space that orbits the Sun, and is not related to the concept of the 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.
Thomas Aquinas was entirely unaware of the big bang hypothesis. Aquinas was a 13th century Sicilian monk, while the big bang concept was first developed in the early 1960s. So, he would not have been able to refute it.
Biggus Banguss springs to mind. However, the ancient Romans had no concept of the "Big Bang" and are unlikely to have coined a word for it. Caboomus Magni? Magna Boomba? Craccus Major! The term Big Bang was coined by opponents of the theory, and used mockingly at first. You are likely today to see references to 'inflation' or 'expansion' in discussions of the big bang. Be on the look-out; they might be references to the big bang itself.
The spread of mass and space. The matter-antimatter collisions HAD to happen after the big bang.
The Big Bang is not an example of free energy. Free energy typically refers to the energy available to do work, whereas the Big Bang was the initial explosion that marked the beginning of the universe and is not related to the concept of free energy.
The big bang theory fits the evidence as we now know it, uniformitarianism is just a lost remnant of the concept that the universe has always been here.
The question is illogically formulated. According to those that believe in God,there was no Big Bang. The concept of God and creation is such that Godwilledcreation into existence. According to creationists God didn't create or cause the Big Bang because, not being mentioned in The Bible/Torah, it never happened.According to scientists, there is no empirical evidence forthe concept of God. Subsequently, there are no theories that include or rationalize a God-like creation. While some even talk about the concept of a'god' particle that started the process, this is more of a media term than a recognized scientific acknowledgement for the concept ofGod.
