Did the universe come from a singularity?

Question

Want to hear some theory's on the big bang, or anything else you think started the universe, go on, go nuts!
(No religion please)

Answer 1

In physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space (in accord with the Robertson-Walker model of general relativity) as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.

Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity (for reporting on some of the more notable speculation on this issue, see cosmogony).

The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began — calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) — and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.

From this model, George Gamow in 1948 was able to predict, at least qualitatively, the existence of cosmic microwave background radiation (CMB). The CMB was discovered in 1964 and further corroborated the Big Bang theory, giving it an additional advantage over its chief rival, the steady state theory.

Is there any rule or compulsion that it really is going to go back from someplace ? the position did the wonder in sugar come from? the position did the chillness in the ice come from? If singularity got here from someplace , ought to you no longer account for its coming there from someplace else and so on without finality ? the position did God come from?How did he come there and type the position did he come there ? .singularity isn't a ingredient or textile .it really is a intense high quality of forte. No body can educate that it got here from a singularity .it really is an assumption yet all of us do not ignore that remember is indestructible and so ,it really is going to have had no starting up or entering life .it continuously existed .The universe we communicate of, being made up of remember , it has continuously existed .The re became no time that it under no circumstances existed .although the life ought to no longer were what it really is to day .each thing is going by using a approach of replace ( no getting older as getting older ought to propose that there ought to were a starting up ) the remember ought to were interior of this kind of potential debris forming gases, then beverages ,semi solids ,solids and metals .because the type of electrons in the atoms of aspects in the remember advance ,the substance transformations into some thing else .subsequently the entire universe is persevering with to regulate .

Answer 3

The Big Bang theory is based on the fact that the universe is constantly expanding.

Answer 4

LOOK there are different theories.
according to big bang of course everyting is formed of singularity. because a big bang which means something like a blast.after energies were released then different changes took place according 2 evolutonists these changes helped in formation of life molecules. then those were developed to cells. as it was necessary 4 single cell 2 b in water. then that cell divided. then formed a a developed body. that came out of water and here i m answering ur Q. dont u think its like. chemical reactions were done forming some alloys. those alloys then accidently met metals. that was found by me. i developed it and that was used by me as a computer. isnt it the same fairy tale. come on either believe both the fairy tales or believe that aSUPREME POWER helped all those cells survive even in THOSE hard conditions. email me even if u dont like my ans.

Answer 5

I believe something like the Big Bang happened...that would explain why certain things are radioactive, holding on to some of that massive energy from way back when...

Answer 6

So it would seem. But since nobody actually saw it, who's to say for certain.
