I am not certain of this but I believe that a Reissner-Nordström (charged) black hole would polarize virtual particles driving away particles of the same charge, while attracting the opposite charge making them more likely to fall into the even horizon and cancel any net charge the black hole...

While it is true that normal (approximate a lunar mass or above) black holes take in more energy from the CMB then they emit, it does not mean they emit zero black body radiation. So yes they are not evaporating (loosing mass), if they net more energy taken in then they emit. The reference...

i do not know for sure but i think ZirkMan may be trying to elude to something like this Since: E=MC^2 and KE+PE=constant When relativistic mass is M in E=MC^2 , could KE+PE be substituted for E and expressed as KE+PE=MC^2 i don't know if that is what ZirkMan was trying to express, if it is...

I hope this is an appropriate forum for this question. What kind sort of impact might intensely blue shifted cosmic microwave background (CMB) photons have on hawking radiation? Could intensely blue shifted CMB photons drive a portion of newly created electrons and positrons into the even...

i read on http://news.nationalgeographic.com/news/2006/09/060915-oldest-galaxy_2.html Chainoth and Ich suggest that the neutral hydrogen was transparent to the back ground radiation. Is the light the article was referring different then the back ground radiation, like say light from hydrogen...

At todays temperature the effect is truly very small indeed. What would the effect have been with the same velocity just after photon decoupling? Wikipedia says the universe's temperature was about 454,000K then

I accept that the effect is very small for non relativistic matter, even more so as the CMB has cooled down to what it is today, but I have not seen it accounted for in any model. I could have over looked some ones work. Every one has an idea for a model. I read on Wikipedia, the Earth and...

This thread on entropy has made me wonder about the universe's level of entropy just before photon decoupling and compare that with the level of entropy just after its assumed that just before photon decoupling the distribution of matter and energy was quite homogeneous, therefor the ability...

I made a mistake and should have seen dark matter signature loosely stated as accelerating matter without regular matter to account for it, while CMB radiation pressure differentials would put the breaks on motion with respect to the CMB and may end up requiring even more Dark matter to explain...

I Imagen a dust cloud circulating around a galaxy in motion with respect to the CMB radiation. The CMB radiation should exert a pressure difference on this cloud slowing its rotation around the galaxy. I don't have the math to prove that, or by how much, but my gut tells me that there is a...

I have posted a question in another thread https://www.physicsforums.com/showthread.php?t=424244 . It asks if CMB radiation pressure differences that arise from motion with respect to the CMB reference frame, when considered on the scale of galaxies and billions of years, do away with the need...

With respect to the surface of the balloon no location on the surface is the center of expansion At time 0, the balloon was a point. As time progresses from then, it expanded into what we see now. The time/space location of point at time 0 only exist in the past and not in the present...

I meant a preferred reference frame with respect to motion but not location. My bigger question is will it lead to radiation pressure that would put the brakes on motion with respect to this preferred reference frame.

For a long time, I have wondered if space has a preferred reference frame. As one looks at the cosmic microwave background radiation, ask your self what would it look like if I accelerated myself in one direction. You would expect a bluer shift in one direction and redder shift in the other...

Would tidal locking arise from gravitational anomalies such as a mountain range pulling on the moon, effectually slowing Earth's rotation while adding that angular momentum to the moon rotation around the earth? I am wondering generally how much energy is lost from Earth's rotation daily...
