>> Shando, You need to see recycling as a different process than salmon returning to the place of their birth.

Good, because what you said made me think that "salmon returning to the place of their birth" is what you meant. Please explain further.

>> Clearly photons move in one direction and never return ...

Up above you said: "If photons come from somewhere why can't they return there". I didn't notice that you had changed from "return" to "recycle". So now you are saying that photons 'recycle' [I don't understand what that means] without a 'return' to the source?

>> ... so don't make dumb connections with things having nothing in common with recycling.

Strike 1: if you refer to my comments as 'dumb' then there is probably no point in continuing this dialogue. I made what I consider to be a reasonable inference from your comments - if they are 'dumb' maybe you didn't communicate your meaning all that well.

>> You agree the photon in(sic) emitted from an atom so we have as a given now-right?

Yes.

>> They have energy and energy is equal to mass-right?

Yes, but not at the same time. If energy, then not-mass. If mass, then not-energy. They seem to be all energy, with no measurable mass. Yet they react to gravity.

>> So, lets use the mass radiated from a star and attempt to explain how that mass can be accounted for.
>> The current belief is helium has less mass than four protons.

I am not aware of this.

>> Have you even done the math to determine if that adds up?

NO, have you?

>> IMO, we don't have a clue as to how to account for the emitted mass from a star.

Really?

>> At the same time we don't have a clue as to how photons transform to protons.

I have never heard of this happening.

>> But, photons flow from atoms and transform into protons.

Do you have any evidence that this happens?

>> This simple fact may never be discovered by our science given internal shortcomings that have developed over the years.

Ah! That is why I haven't heard about this remarkable transformation.

IMO, belief without evidence = religion. No?

Shando, I'm sure you will at least agree a lot of photons flow from the sun and all stars. I get a count somewhere around 10^45/s. What do you estimate the count to be? Just to be clear you can divide the mass estimate of the energy flux and get a good idea about the mass of one photon-right?

Yes, I certainly agree that a huge number of photons flow from stars - as to the quantity, I have no idea. And I have no idea how to measure the amount of flux.

Shando, I'm sure you will agree the sun radiates about one watt per five thousand kilograms and you can do a lot with that fact. All you need to do is use what is well known to determine how many photons are equal to one watt-right?

This is news to me (my ignorance). Is that 1 watt per second?

>> All you need to do is use what is well known to determine how many photons are equal to one watt-right?

If the first fact is true, and we knew the total mass of the sun and how many photons in total are given off per second by the sun, we could probably develop a reasonably good estimate of the rate of photon production.

Shando, A watt per second is a joule-right? The solar flux of one watt per 5,000kg is a constant unrelated to time.
