How many earthquakes has there been since the big bang?
We do not currently know and in fact we may never know. Due to the nature of the big bang, and the fact that all space, matter and energy are a direct result of it, there is no way to accurately detect anything outside of its scope. Everything we know about the universe comes from observing and analyzing the universe around us. Since the universe we know did not exist before the big bang there is nothing we can learn about the "before time" from observing the universe we live in. There may have been a universe before that which went into a "big crunch" which led to the big bang of our universe. It is natural to assume that if that were the case then that previous universe must have also had its origins in a big bang as well, and perhaps its all part of a huge cycle. In fact, since the big bang is the origin of everything in our universe, including space itself, it may also be the origin of time itself, and so there may not have been a "before" the big bang. But more to the point, in order for another big bang to occur, the universe would have to be compressed in a "big crunch" into a singularity before that could happen. There are some theories which point this direction, and there are some which do not.
How long has hydrogen been around?
Henry Cavendish, a young English chemist, discovered that hydrogen is a separate substance in 1766. It was also discovered that hydrogen is found naturally in the atmosphere, and when hydrogen is burned it produces water vapor
Has the earth been cooling since 1998?
Yes of course. The Earth has been cooling ever since it's creation 4.5 billion years ago.
How long has Canada been around?
since 1980 the independent Canada has been around
What natural resources are found in the sahel?
not much of anything. certainly not water since it has been in a drought since the 70s.
What did the big bang scatter through space?
The Universe! Initially everything was crammed into an infinitesimally small point but since the Big Bang all the matter and energy that make up our Universe has been expanding outwards.
How is nuclear energy created or formed?
Uranium formed in supernova explosions. Hydrogen has been in the universe since milliseconds after the big bang.
What was the initial size of the universe before the Big Bang theory?
The entire OBSERVABLE Universe must have been smaller than the size of a proton. Since the ENTIRE Universe is much larger, and perhaps infinite, we really don't know how large that was.
How old was the universe when the big bang thory happened?
Events in the Universe are often dated from the Big Bang. But the fact is, NOBODY KNOWS what (if anything) happened before the Big Bang. The Big Bang MAY have been the start of time itself; but it is possible that the Universe existed (in some form) forever in the past.
If there was no big bang what would the universe be like now?
Exactly the same, there was no big bang!! That theory has been proven wrong.
What does the big bang theory tell us about current size of the universe?
Not much, unfortunately. We know that our Universe is expanding, and has been for about 13.7 billion years. The problem is, we can only see light from objects that has had time to reach us since the Big Bang. Thus, we can only know about the "observable" universe. How much more of our Universe is outside our present field of vision is still speculative at best.
What is one of the primary unaswered questions about the origin of the universe?
It was what came before the big bang, and the big bang theory states that the universe started as a dense nucleus of matter: a huge amount of matter concentrated in a tiny spot. This is the conclusion of equations and evidences that prove that the universe has been and continuous to expand: since it has been expanding, there was a moment when it was as small and dense as it is possible . So, the expansion is the result of violent explosion. The time during which the expansion has been happening (this is how long ago the big bang occurred) has been estimated thanks to the observation of the speed of recession of the galaxies, but nothing can be told about what came before the big bang occurred .
How does the big bang theory suggest the univeruse formend?
It doesn't. The Big Bang simply states that, about 13.7 billion years ago, the space that holds our Universe began to expand and has been doing so ever since. The evidence for this is pretty overwhelming. The questions, "WHY did space start to expand?" and "Why does space continue to expand?" are, at present, as unresolved as "Why is there lightning in the sky?"
What was the condition before the Big Bang?
The earth only came into being about 9 billion years after the big bang.At the time of the big bang, not even the atoms that make up the earth existed as atoms. And, since the big bang brought the universe into exsistence, the question of what anything was like before the big bang is impossible to answer.(Ain't cosmology fun?)
How is the origin of universe explained?
There is a lot of evidence that some 13.8 billion years ago, the Universe was in an extremely dense and hot state, commonly called the "Big Bang", and that since then, it has been expanding.It is not currently known what happened before that.
How did the Big Bang go from being an idea to a theory?
Spectral analysis of various distant stars and galaxies showed a Doppler effect that was indicative of an expanding universe, which is exactly what one would expect if the universe had been created in a huge explosion. Since then, there has been a great deal of other astronomical observation that is consistent with the Big Bang Theory. It is very solidly confirmed.
What theory do scientists accept as an explanation for the origin of the universe?
Still now the most acceptable theory on the origin of universe has been the big bang theory. you can get more info on big bang theory from wikipedia.
