Quasars and Dyson Spheres

Sheap · #1 03-09-2006, 10:53 PM

Quasars are black holes moving so fast that they have unbelievably high redshift right?
Dyson spheres are theorised spheres around stars that absorb all of the energy from the stars, and reemmit it as infrared right?
I came up with an idea that it might be possible that some of what we have identified as quasars could be dyson spheres, that instead of reducing light to a certain frequency, maybe they just reduce the energy of each photon that they absorb by a certain amount. I believe that this would give the illusion of a huge redshift, and would supply a huge amount of power for anyone using it.
Do light from quasars lose light intensity as they get further away? they are moving away at such a speed that they should, and if this is not the case, i believe that my theory should at least be considered.

interesting idea, but how would you account for the shifted absorption & emission lines in the spectrum?

To be totally honest, im just going on what i remember about quasars, ill have a look at that and see if i can find a way for it to fit in. But from the top of my head, the absorption & emission lines will be shifted because they are drained of their energy somehow, and reemitted at a lower energy level, and hence redshifted, this is why i said that each photon is reduced by the same amount of energy, as this would give all those lines the illusion of being redshifted, while in actual fact they are being drained of their energy.

Hi Sheap
What you are saying sounds like the "tired light" theory (it is an idea only and has no support via data or experiment) which seeks to explain redshift as a condition of "tired light". I recall the unacceptability of the proposal was that a photon could not lose energy (as envisaged by the tired light approach) so as to create the shift.
Leaving that aside what interpretation do you place of the data if interpreted via your approach? I gather you suggest they (quazars) may be further distant if the data was interpreted taking into account your premise? How do you (or do not) overlay the "accepted fact" that the Universe is expanding via your idea.

From what you say about the "tired light" theory, the photons would be losing the energy themselved, i am stating that photons are stripped of their energy by some technology.
My theory only affects the interpetation of data from quasars, i do not disagree with the expanding universe theory. By my theory predicts quasars are a lot closer than predicted, the accepted theory is that they are objects moving away at large speeds (up to 0.8c as i recall) and this high speed gives the redshift we observe, i am merely proposing that this redshift could also be a result of some photons losing energy.

I think "the tired light" problem exposes the possible problem but lets not worry about that I can see your point and why you arrive at it. If anyone disagrees give them a tape measure and tell them to check it for themselves. The tired light thing suggests that our expansion could be an illusion and that there was no big bang leaving us in a steady state condition, a favoured view of one time, but not now. Keep up the research.
