What temperature does COBE find the Big Bang has cooled to by now?

Answer 1

The universe began at what is called the Planck Era when time was smallest unit of time which is 1.35 x's 10 -43 of 1 second and lasted until time was 10 -36 second so Planck era was such a short amount of time 1 /1000000000000000000000000000000000000 of 1 second that light only traveled about 1 /100000000000000000000000000000 of 1 foot during Planck Era . At 1.35 x's 10 -43 second temperature was 179999999999999999999999999999540.6 degrees Fahrenheit is same as 179,000,000 trillion trillion is the same as 179 million X'S 1 trillion and result X'S 1 trillion degrees F. At time 10 -36 second the temperature was 1799999999999999999999999540.6 degrees F is same as 1799 x's 1 trillion and result x's 1 trillion degrees F. There are 5 different "eras" which take place in the first 1/millionth of a second after the universe began. I won't explain them here, look them up on you tube for more information about individual 5 eras that make up total of first 1/million of a second after the universe began. During the Planck Era light only travels about 1 / 1000000000000000000000000000000000000 of 1 foot because it is such a short amount of time.

The Inflationary period of big bang universe began at 100 billion x's trillion x' trillion of 1 second after universe began. During inflationary period universe expanded from less than size of 1 atom (microscopic) to at least 0.1691201334439385028 of 1 light year in diameter but could be even bigger (this is same as 994193907579.7344 miles diameter (1 trillion miles) This expansion period began sometime between 10 -35 to 10 -32 second and ended at 10 -12 second. The temperature at time big bang began was the same as I wrote above at time 10 -36 of 1 second. Actual speed of big bang was exactly 3579098067287043840000000000.0000000357909806728704384 miles per hour without partial mile is written as 3579098067287043840000000000 miles per hour and ending size was minimum of 0.1691201334439385028 of 1 light year in diameter.

At time 10 -12 second (written 0.000000000001 second) is same as 1 trillionth of a second after universe began the temperature was 1799999999999540.6 degrees F. At time 10 -6 second (written 0.000001 second) is 1 millionth of a second after universe began temperature was 17999999999540.6 degrees F (Fahrenheit). All this above is the speed of space between actual mass. Mass is material that existed during the big bang and later formed current galaxies. The mass never moved faster than the speed of light (during big bang) but space between the mass did. Today we still have space between mass (today mass has formed galaxies) that existed during big bang. The difference in average expansion (space expands like baked cookie doubling in size about one time per 9.7 billion years and continually in future too). Universe today is 13.8 billion light years old but space between mass (galaxies) is at least 85 billion light years diameter today (due to faster speed of space between galaxies than mass itself. Galaxies themselves (mass) never expand faster than speed of light.

Answer 2

We have no way to calculate what temperature the big bang would have been, nor any way to know if that question makes any sense in the context of a universe that abruptly emerges from nothingness.

Philosophically, the answer probably is as close to "infinite" as anything could be.

Answer 3

infinity at the exact time of the big bang. now 2.7 degrees K going back to zero, and the cycle begins again.

Answer 4

The size of the universe expanded after the big bang and is still expanding today. The temperature of the universe has lowered and has been distributed throughout the universe.

Answer 5

The Universe was at 3000 degrees K at conception, and since then, the universe has expanded by a factor of 1000. The latest revised temperature is at 3 degrees K.

Answer 6

2.7 kelvin.
