Answer 2

Dellian is totally out to lunch!!

As insight is garnered from quantum physics, the actual process at time zero is hotly debated. There are several theories about the birth of the universe (and spacetime), the Big Bang has definitely not been proven to be conclusive by science or anything else, other than voodoo!

JBarleyCo is more on point than Deliian is, but as JBarleyCo says that is an oversimplification.

Answer 3

You are going to get all sorts of answers here, I go for the scientific approach.
What are you going to believe, modern science or a book that was written during the Bronze age ? Written thousands of years before the invention of the telescope and microscope, before we were allowed to see how everything in the universe, both very large and very small, really works? Up till very recently it was heresy to say that the earth revolved around the sun. The Catholics have only just come to terms with evolution, yet they still think the virgin Mary shot up into heaven when she died, a story that was made up 600 years after Christ's death! Religion has held back scientific progress.

Answer 4

In the beginning, God created the heavens and the earth. Genesis 1:1. and I bet that wasn't what you were looking for, but I'm a Jesus freak and that's how it WAS created.

Answer 5

You'll have to look that one up - it's complicated and I'm not sure if completely understood yet. Basically, like a star, a lot of gas that is drawn together through gravity, but that is really simplifying it.

Answer 6

Ahahaha! Yes "God" did it...
Don't believe that... Science has proof of The Big Bang, science can proves most of the things it claims.... while religion cannot... Remember this.
Now let's all bow down and pray for more beer.

Answer 7

the Milky Way is thought to comprise a large barred spiral galaxy of Hubble type SBbc (loosely wound barred spiral) with a total mass of about 600 billion to 3 trillion solar masses (M☉)[2][3], comprising 200 to 400 billion stars. Its integrated absolute visual magnitude has been estimated to be -21.3.

It was only in the 1980s that astronomers began to suspect that the Milky Way is a barred spiral rather than an ordinary spiral, which observations in 2005 with the Spitzer Space Telescope have since confirmed, showing that the galaxy's central bar is larger than previously suspected.[4]

The galactic disk, which bulges outward at the galactic center, has an estimated diameter of about 100,000 light-years. The distance from the Sun to the galactic center is now estimated at 26,000±1400 light-years while older estimates could put our parent star as far as 35000 light-years from the central bulge.

The galactic center harbours a compact object of very large mass (named Sagittarius A*), strongly suspected to be a supermassive black hole. Most galaxies are believed to have a supermassive black hole at their center.

As is typical for many galaxies, the distribution of mass in the Milky Way is such that the orbital speed of most stars in the galaxy does not depend strongly on its distance from the center. Away from the central bulge or outer rim, the typical stellar velocity is between 210 and 240 km/s.[5] Hence the orbital period of the typical star is directly proportional only to the length of the path travelled. This is unlike in the solar system where different orbits are also expected to have significantly different velocities associated with them, and is one of the major pieces of evidence for the existence of dark matter.

The galaxy's bar is thought to be about 27,000 light years long, running through the center of the galaxy at a 44±10 degree angle to the line between our sun and the center of the galaxy. It is composed primarily of red stars, believed to be ancient. The bar is surrounded by a ring called the "5-kpc ring" that contains a large fraction of the molecular hydrogen present in the galaxy and most of the Milky Way's star formation activity. Viewed from the Andromeda Galaxy, it would be the brightest feature of the Milky Way [6]

Each spiral arm describes a logarithmic spiral (as do the arms of all spiral galaxies) with a pitch of approximately 12 degrees. There are believed to be four major spiral arms which all start at the Galaxy's center. These are named as follows, according to the image at right:

2 and 8 - 3kpc and Perseus Arm
3 and 7 - Norma and Cygnus Arm (Along with a newly discovered extension - 6)
4 and 10 - Crux and Scutum Arm
5 and 9 - Carina and Sagittarius Arm
There are at least two smaller arms or spurs, including:

11 - Orion Arm (which contains the solar system and the Sun - 12)
Outside of the major spiral arms is the Outer Ring or Monoceros Ring, a ring of stars around the Milky Way proposed by astronomers Brian Yanny and Heidi Jo Newberg, which consists of gas and stars torn from other galaxies billions of years ago.

The galactic disk is surrounded by a spheroid halo of old stars and globular clusters approximately 250,000 to 400,000 light years in diameter[7]. While the disk contains gas and dust obscuring the view in some wavelengths, the spheroid component does not. Active star formation takes place in the disk (especially in the spiral arms, which represent areas of high density), but not in the halo. Open clusters also occur primarily in the disk.

Most of the mass of the Milky Way is thought to be dark matter, forming a dark matter halo of an estimated 600-3000 billion solar masses (M☉) which is concentrated towards the Galactic Centre.[3]

Recent discoveries have given added dimension to our knowledge of the structure of the Milky Way. With the discovery that the disc of the Andromeda Galaxy (M31) extends much further than previously thought,[8] the possibility of the disk of the Milky Way extending further is a clear possibility and is supported by evidence of the newly discovered Outer Arm extension of the Cygnus Arm.[9] With the discovery of the Sagittarius Dwarf Elliptical Galaxy came the discovery of a ribbon of galactic debris as the polar orbit of Sagittarius and its interaction with the Milky Way tears it apart. Similarly, with the discovery of the Canis Major Dwarf Galaxy, a ring of galactic debris from its interaction with the Milky Way encircles the galactic disk.

On January 9, 2006 Mario Juric and others of Princeton University announced that the Sloan Digital Sky Survey of the northern sky has found a huge and diffuse structure (spread out across an area around 5,000 times the size of a full moon) within the Milky Way that does not seem to fit within our current models. The collection of stars rises close to perpendicular to the plane of the spiral arms of the Milky Way. The proposed likely interpretation is that a dwarf galaxy is merging with the Milky Way. This galaxy is tentatively named the Virgo Stellar Stream and is found in the direction of Virgo about 30,000 light years away.

On May 9, 2006, Daniel Zucker and Vasily Belokurov announced that the Sloan Digital Sky Survey has discovered two dwarf galaxies towards the constellations Canes Venatici and Boötes.

Answer 8

Big Bang. I have the "Birth of The Universe" on mpeg if ya want it, Great show

Answer 9

By God, obviously! who dares to deny this?
