Cerenkov replied to the thread A Strong Progenitor Age Bias in Supernova Cosmology.Hello Peter I'm interested in the issue of the universe's apparent accelerated expansion and would like to learn more. Could you... -
Cerenkov replied to the thread I Where did the early photons go?.Thank you. I also take your point about BB nucleosynthesis. For that to happen the temperatures and densities must have been very high...

Cerenkov replied to the thread I Where did the early photons go?.This is for PeterDonis' attention, in reply to him. But if anyone wants to pitch in with corrections, clarifications or explanations, I...

Cerenkov replied to the thread I Where did the early photons go?.Ok, thanks. You needn't worry about me reverting to a kind of Newtonian way of thinking about this, btw. When I read your words above...

Cerenkov replied to the thread I Where did the early photons go?.Ok, thanks for this clarification Peter. I'll take that on board. :smile:

Cerenkov replied to the thread I Where did the early photons go?.jbriggs444 What you describe is difficult to envisage for the layman who can't to do the math to understand it that way. But through...

Cerenkov replied to the thread Does it make sense to build new radio telescopes?.Replying to the questions put to you doesn't seem to be your forte, does it Line_112? I put four to you and you respond to just one. A...

Cerenkov replied to the thread Does it make sense to build new radio telescopes?.Why would you predicate your argument on such an average? Could you please explain your reasoning and how you arrive at the conclusion...

Cerenkov replied to the thread Does it make sense to build new radio telescopes?.Ok, this isn't about radio telescopes per se, but it's about the 'why bother about space if it doesn't affect us' attitude. In 2013 the...

Cerenkov replied to the thread Does it make sense to build new radio telescopes?.Provided that we keep on building bigger and better radio telescopes, it's a win - win scenario, Line_112. If they detect no other...

Cerenkov replied to the thread Does it make sense to build new radio telescopes?.One might well ask, does it make any sense to build new optical telescopes like the EELT? Or new space-based telescopes like the JWST...

Like.
So, @Line_112 , are you just going to ignore the many redshift measurements of GRBs that have been made? These measurements firmly... -

Why do you think this? It is an equal area projection. So dots of the same area will cover the same area of the sphere.
-
Cerenkov replied to the thread A Could gamma-ray bursts have an intragalactic origin?.I see. The map you posted does give preference to the extragalactic origin of GRBs because there is no clustering of them on the plane...

Cerenkov replied to the thread A Could gamma-ray bursts have an intragalactic origin?.Then, if you found nothing to support your claim and if you rely on others to clarify the issue, your claim (that absorption is...
