The big bang theory
Theories of the universe are cosmologies. There are three main theories concerning our universe. These are the big bang theory, the steady state theory, and the oscillating universe theory. Each of these attempts to account for the observed expansion of the universe. So far the big bang theory is far and away the strongest of these three. If there was a big bang, there should be microwave background radiation. This radiation has been observed, and the age of the universe calculated to 13.7 billion years.'What are the theories of the universe' in Spanish = 'Cuales son las teorias del universo?'
The main idea is that when the universe started out it was a hot clump of matter then it exploded into what we have today.
The main disadvantage of the Big Bang theory probably lies in our inability. What are the advantages and disadvantages of capital asset pricing model.
I presume you are referring to Jesuit priest Georges LeMaitre, the one who first developed the idea now known as the Big Bang. Arthur Eddington was probably the main supporter of LeMaitre's ideas; Einstein emphatically dismissed them. Edwin Hubble never made any direct statement about BBC, but he did show that one of its predictions was, in fact, correct.
The main evidence is the redshift of distant galaxies; the only sensible explanation is a cosmological redshift, related to an expanding Universe. Other pieces of evidence are the microwave background radiation, which agrees very well with the predictions made by the Big Bang theory, and Olber's paradox - among others.
The main evidence for the Big Bang is the expansion of the Universe, as seen from the Doppler effect. That is, light from other stars or galaxies changes color depending on the relative velocity to Earth; it turns out that all far-away galaxies are receding from us.
Oh dear, this question is really mixed up. The steady state theory is just history now, but the Big Bang is the main current theory. Try again with a clearer version of the question, if you can.
A hypothesis is used to make predictions. Experiments are carried out to test these predictions. If the outcome of the experiment was not as predicted then the hypothesis is falsified. It is either rejected or modified. If the outcome of the experiment confirms the prediction then that provides some evidence that the hypothesis is true.Over time, after testing different predictions, there will be a significant amount of evidence in favour of the hypothesis, and all the main alternatives have been rejected. At that stage the hypothesis becomes a theory.
No one can say. It's just a theoretical explosion that scientist speculate may have occurred long before man was here to witness-assuming it happened. **** Actually, the Big Bang was not an explosion -- it was an expansion. To say scientists "speculate" about, or that it is "theoretical" it is like saying they speculate that our Earth "theoretically" goes around our Sun. Both these facts about our Universe make several predictions about what we would see if they were true. If ANY one these predictions happened to turn out to be false, then scientists would be questioning whether the Big Bang occurred. However, ALL of them have been observed just as predicted by Big Bang Cosmology. To say that the Big Bang "may have occurred" is like saying Anasazi civilization "may have occurred" before anyone was able to write about them. Both cases -- the Big Bang and the Anasazi -- left a LOT of evidence of their existence. Only two groups of people would say that scientists "speculate" the Big Bang "may have occurred" and "assuming it happened": 1) Those totally ignorant of science. 2) Those trying to spread ignorance of science.
the three main ideas of cell theory is all organisms are made up of one or more cells, all cells come from existing cells, and the cell is the basic unit of all organisms.
Actually there are three: Darwin, Mendel and Wallace.
