Mass from redshifted radiation

In summary, the conversation discusses the concept of nonbaryonic matter and its connection to redshifted radiation. It is proposed that the mass of nonbaryonic matter is the energy that has been lost from cosmic microwave background radiation. This means that the overall mass of the universe may increase if the amount of mass originating from redshifted radiation is greater than the loss of mass from other processes. The conversation also mentions the relationship between G, the gravitational constant, and the expansion of the universe, as well as the discrepancies between observations and existing formulas. Finally, there is a discussion about calculating the energy density of the CMB and its potential role in accounting for dark matter and dark energy.

This posting relates to my earlier posting and might explain the nature of one or more forms of nonbaryonic matter. It proposes that the mass of such matter represents the energy lost from redshifted radiation. For example, the energy that has been lost from cosmic microwave background radiation now exists as cold dark matter.

This means that the overall mass of the universe increases if the amount of mass originating from redshifted radiation is greater than the loss of mass from processes such as fusion and accretion.

My earlier posting proposed that G not only functions as the gravitational constant, but paradoxically it also relates to the expansion of the universe by providing the universe with 6.67E-11 m^3 of volume per s^2 for each kg of mass in the universe. Discrepancies arising between the formulas of that premise and observations might now be explained in view of the above infromation about changes of mass in the universe. For example, as with all other matter, new nonbaryonic matter originating from redshifted radiation contributes to the expansion of the universe rather than its collapse do to additional gravity sources.

JMartin, I can't comment on your speculation here but just
want to check to see if you are OK on calculating the
energy density of the CMB


to find the joules per cubic kilometer you would raise the temp (2.73 kelvin) to the fourth power and multiply by
7.57 E-7 (anybody have a different figure?)

since last scattering the wavelengths of CMB have been
stretched by a factor of 1100

that is, it has lost all but about a thousandth of its energy by redshift.

so you should be able to calculate how much energy should be in some other form, per cubic kilometer, if all the lost CMB energy (from the photons in a cubic kilometer) were somehow converted into something else like "dark matter"

it might not be enough to account for the estimated amount of dark matter in a cubic km, or to account for the estimated amount of dark energy

you have to check to see if the books balance

(balancing the books is a necessary but not sufficient condition for the theory to work)

what do you calculate for the lost CMB energy per cubic kilometer?

1. What is "mass from redshifted radiation"?

"Mass from redshifted radiation" refers to the phenomenon in which the observed mass of a distant object appears to be greater than its actual mass due to the redshift of its emitted radiation. This is caused by the expansion of the universe, which stretches the wavelengths of light from distant objects, making them appear redder and thus increasing their observed mass.

2. How is mass from redshifted radiation calculated?

The calculation of mass from redshifted radiation involves using the redshift parameter (z) of the observed object, which is a measure of how much its emitted radiation has been stretched. The observed mass can be calculated using the equation M(observed) = M(actual) * (1+z). This takes into account the expansion of the universe and the effect it has on the observed mass of distant objects.

3. What types of objects exhibit mass from redshifted radiation?

Mass from redshifted radiation can be observed in a variety of objects, such as distant galaxies, quasars, and even the cosmic microwave background radiation. Any object that is emitting radiation and is located at a significant distance from us can exhibit this phenomenon.

4. How does mass from redshifted radiation affect our understanding of the universe?

The concept of mass from redshifted radiation is an important factor in our understanding of the expansion of the universe. By accurately calculating the observed mass of distant objects, scientists can better estimate the amount of matter present in the universe and its distribution. This can also provide insights into the rate of expansion and the overall structure of the universe.

5. Can mass from redshifted radiation be used to determine the age of the universe?

Yes, the study of mass from redshifted radiation can be used as a tool to estimate the age of the universe. By measuring the redshift of various objects and calculating their observed mass, scientists can determine the rate of expansion and extrapolate back to the beginning of the universe. This, combined with other methods of age estimation, can help us better understand the history and evolution of our universe.
