According to the big bang theory how did the temperature and density of the early universe compare to todays?
Big Bang Cosmology contends -- and all observational evidence supports this idea -- that our Universe has been steadily growing less dense and at a lower overall temperature. For example, during the Quark Epoch (between 10^-12 and 10^-6 seconds after the end of Inflation), the temperature was 10^15 K; it's now down to less than 3 K.
What else can I help you with?
According to the Big Bang Theory how have the density and temperature of the universe changed over time?
The "big bang" theory is still relatively new. British astronomer Sir Fred Hoyle came up with the term "big bang" as a derogatory term in the 1950's, because Hoyle was a life-long believer in the "steady state" theory of the universe.
Compare and contrast average density and critical density?
the average density is the total amount of matter in the universe, whereas the critical density is about 10 to the -26th power kg/m cubed (to the third power), the dividing point between a closed or open universe.... :)
Will the universe expand forever will it stop or will it reverse itself according to the general theory of relavitiy it all depends on how much matter is within the universe this all depends on what f?
According to the general theory of relativity, the ultimate fate of the universe depends on its density of matter and energy. If the density is above a certain critical value, the universe will stop expanding and eventually collapse in a "Big Crunch." If the density is below this critical value, the universe will continue to expand forever. Current evidence suggests that the universe's expansion is accelerating, indicating a low density and a future where it expands indefinitely.
Was the Big Bang a singularity?
The Big Bang theory suggests that the universe began as a singularity, a point of infinite density and temperature.
What model asserts the universe will stop expanding A High Density Universe B Low Density Universe C Critical Density Universe D both A and C or E none of the above?
C. Critical Density Universe. This model suggests that the expansion of the universe will eventually slow down and stop, leading to a stable universe.
How can you determine that a coin is not pure silver if you know the mass and the volume of the coin?
The idea is to divice the mass by the volume, to get the density. Then compare to the density of silver.The idea is to divice the mass by the volume, to get the density.

The average temperature of the universe right now is about 2.73 K Will this temperature likely go up or down over the next billion years?
The average temperature of the universe is expected to decrease over the next billion years due to the continuous expansion of the universe. This expansion will cause the overall energy density to dilute, leading to a decrease in temperature.
What does it mean to compare the density of an object to that of it in pieces?
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare
What was before the singularity?
Before the singularity, there was a state of infinite density and temperature in the universe. This state is believed to have existed at the beginning of the Big Bang, which is the current scientific theory explaining the origin of the universe.
Density of CdS?
The density of Cadmium Sulfide (CdS) is approximately 4.82 grams per cubic centimeter at room temperature.
Which has greater density-1kg of platinum or 3kg of gold?
When you compare density, you compare the weight of the materials with equal volume. So you cannot compare the density only by weight. The right answer for this is, Platinum has the density of 19.8 gr/cubic centimeters at room temperature versus Golds 19.3 gr/cm3.
How does density change as the universe expands?
The density of what? Any metal, liquid, etc. will have the same density since density depends on mass and volume of the sample (not volume of the universe).
