How do u think the universe was created?

Answer 1

The Universe is defined as the summation of all particles and energy that exist and the space-time in which all events occur. Based on observations of the portion of the Universe that is observable, physicists attempt to describe the whole of space-time, including all matter and energy and events which occur, as a single system corresponding to a mathematical model.

The generally accepted scientific theory which describes the origin and evolution of the Universe is Big Bang cosmology, which describes the expansion of space from an extremely hot and dense state of unknown characteristics. The Universe underwent a rapid period of cosmic inflation that flattened out nearly all initial irregularities in the energy density; thereafter the universe expanded and became steadily cooler and less dense. Minor variations in the distribution of mass resulted in hierarchical segregation of the features that are found in the current universe; such as clusters and superclusters of galaxies. There are more than one hundred billion (1011) galaxies in the Universe,[1] each containing hundreds of billions of stars, with each star containing about 1057 atoms of hydrogen.



The most important result of physical cosmology—that the universe is expanding—is derived from redshift observations and quantified by Hubble's Law. That is, astronomers observe that there is a direct relationship between the distance to a remote object (such as a galaxy) and the velocity with which it is receding. Conversely, if this expansion has continued over the entire age of the universe, then in the past, these distant, receding objects must once have been closer together.

By extrapolating this expansion back in time, one approaches a gravitational singularity where everything in the universe was compressed into an infinitesimal point; an abstract mathematical concept that may or may not correspond to reality. This idea gave rise to the Big Bang Theory, the dominant model in cosmology today.

During the earliest era of the big bang theory, the universe is believed to have formed a hot, dense plasma. As expansion proceeded, the temperature steadily dropped until a point was reached when atoms could form. At about this time the background energy (in the form of photons) became decoupled from the matter, and was free to travel through space. The left-over energy continued to cool as the universe expanded, and today it forms the cosmic microwave background radiation. This background radiation is remarkably uniform in all directions, which cosmologists have attempted to explain by an early period of inflationary expansion following the Big Bang.

Examination of small variations in the microwave background radiation provides information about the nature of the universe, including the age and composition. The age of the universe from the time of the Big Bang, according to current information provided by NASA's WMAP (Wilkinson Microwave Anisotropy Probe), is estimated to be about 13.7 billion (13.7 × 109) years, with a margin of error of about 1 % (± 200 million years). Other methods of estimation give different ages ranging from 11 billion to 20 billion.[6] Most of the estimates cluster in the 13–15 billion year range.[7][8]

In the 1977 book The First Three Minutes, Nobel Prize-winner Steven Weinberg laid out the physics of what happened just moments after the Big Bang. Additional discoveries and refinements of theories prompted him to update and reissue that book in 1993.

Answer 2

God is the single that created this universe and notice what Quran says approximately it ,Surat Al-Baqarah 2:163,164,one hundred sixty five And your god is one God. there is not any deity [worth of worship] different than Him, the completely Merciful, the quite Merciful. certainly, interior the advent of the heavens and earth, and the alternation of the night and the day, and the [super] ships which sail throughout the time of the sea with that which advantages human beings, and what Allah has sent down from the heavens of rain, giving life thereby to the earth after its lifelessness and dispersing therein each and every [sort of] shifting creature, and [His] directing of the winds and the clouds controlled between the heaven and the earth are indications for a people who use reason.And [yet], between the persons are people who take different than Allah as equals [to Him]. They love them as they [could] love Allah .

Answer 3

Just answering your question from a wider viewpoint:

EITHER you have to accept a first event, which, therefore cannot have a cause (or it wouldn't be the first event).

OR you have to assume that you can go back infinitely in time, and "first" has no meaning;

OR you have to rethink what time itself means.

None of these options is particularly intuitive, but you have to choose one.

If you choose “God”, then instead of “How do u think the universe was created?”, you have to ask “How do u think God was created?”, which is exactly the same question, just with “the Universe” renamed as “God”.

Answer 4

A quantum fluctuation. Nothing, not even empty space, can stay exactly still according to quantum physics. There is always some fluctuation, albeit very tiny but still always there. But size is relative, and so our universe may be a tiny quantum fluctuation of another universe too large to imagine (compared to our own, as if our own wasn't already too large to imagine).

Answer 7

I think it was engineered by advanced beings in a previous universe as a replacement for theirs. When ready they moved in. They are waiting for us to get smart enough to meet them.

Answer 8

Well.... So far the 'Big Bang' theory seems to nicely fit all of the observable data.

Answer 9

Obviously, the Big Bang. Do your reasearch!

Answer 10

I don't think it was "created" at all. It just is and always will be.
