How does background radiation support ''the big bang theory''?

Answer 1

The Big Bang supports interpreted observational evidence for an evolutionary expansion of the universe and rationalization for a finite age of the universe. The Big Bang implies that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.

Answer 2

Background radiation is consistent with the Big Bang theory because it is the leftover radiation from the early hot and dense universe that has since cooled and expanded. The discovery of the cosmic microwave background radiation in the 1960s provided strong evidence for the Big Bang theory by matching the predicted characteristics of radiation left behind by the intense energy of the initial expansion.

Answer 3

we all need an answer and this hypothesis is the best theory that mankind knows. It developed to reflect observation of data, and in fact is now considered overwhelmingly accurate back to several milliseconds after the actual Bang.

Answer 4

Because everywhere we look in the night sky there is heat. If the big bang did not occur then technically areas where there is not any stars should have no heat. But this is not the case, the average temperature of the universe is about 2 kelvin. This is due to the fact that the big bang left behind heat that is currently being dissipated through the expansion of the universe. The temperature will keep going down but will never actually reach 0 degrees kelvin.

Answer 5

The Big Bang theory proposes that the Universe began in a microscopic super-dense, super-hot state, which expanded to become the Universe we see today.

This early state implies that the Universe should be full of radiation created in that fireball; as the Universe expanded, that radiation cooled, and should now be perfect blackbody radiation at a temperature of around 3 degrees Kelvin. (Actually, the original temperature prediction was higher, but that was before the exact age of the Universe was known, and was also subject to some other technical modifications that reduced the original prediction.)

When the cosmic background radiation was discovered, it fit these predictions perfectly, which gives a fair amount of evidence that there is some truth behind the theory. Attempts to explain the cosmic background radiation were made in the context of the Big Bang's chief competitor, the Steady State theory, but proved to be unsatisfactory.

So the cosmic background radiation supports the Big Bang Theory because the theory predicted its existence, its temperature, and its form.

Answer 6

The Big Bang Theory present the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang Theory promotes four concepts for consideration:

1. that the observable universe is Time bound (or has a finite existence)

2. that the observable universe is expanding (within the dimensional limits of Space and Time),

3. that the observable universe is evolving a set amount of matter and energy while it is expanding over time, and

4. that the observable universe is homogeneous and isotropic with respect to Space and Time.

Answer 7

Before the CMBR was ever observed, it followed from the Big Bang theory that the CMBR should have a particular temperature, and that the variations in the background should have a particular distribution and range of sizes. The CMBR, when it was detected, matched those predictions very closely.

Answer 8

Among other things, our GPS systems, defense systems and communications networks would not work properly if we did not know how to adjust for relativistic effects as predicted by Einstein's equations. Relativity has been verified in a number of ways and has not yet been refuted, so relativity has helped shape and direct a great deal of subsequent research. Relativity is also helping us, little by little, come to better cosmological concepts.

Disagreement:

(1) Apparently our GPS systems do not use Special Relativity, although that fact is hidden in the math. See:

3. Wang, Ruyong. Successful GPS Operations Contradict the Two Principles of Special Relativity and Imply a New Way for Inertial Navigation - Measuring Speed Directly. Proceeding of the IAIN World Congress in association with the U.S. ION Annual Meeting, 26-28 June 2000, San Diego, CA.

(2) Einstein created a very complete and complicated theory of Special Relativity. Beckmann realized that a simpler system could work, and he favored gravity as the "aether" for light. I think, however, that the electromagnetic fields that exist (everywhere) can "carry" the electromagnetic "waves" (i.e., light). I am not allowed to show you the link. It is amazing how far afield we can drift.

Answer 9

The temperature of the CMB was one of the predictions following from the Big Bang model. Finding that the actual temperature was a close match to the prediction was an important confirmation of accuracy of the model.

Answer 10

The main disadvantage of the Big Bang theory probably lies in our inability to explain where the original "ball" of energy came from that did the expanding (the "Bang") to form the universe and the spacetime that it occupies. Note, if you please, that the universe did not expand into an "empty" universe or volume of space, but involved all the energy that "condensed" and the creation of spacetime in which to exist.
