And yet in terms of the number stars producing photons capable of reaching the Earth at any given second would result in a background temperature of around 3 degrees. You seem to be dismissing the whole distance aspect, the effect of the inverse square law, and ignoring the fact that suns aren't even infinite temperature to begin with. We only see about 8400 stars of the hundreds of billions of stars in our own galaxy, so your assertion is easily demonstrated to be false. If you were correct we would have to be able to see every star in our local galaxy cluster. It simply doesn't work like that.
At enough distance, suns at even a *finite* distance are incapable of producing photons that can reach the Earth, and photons only travel a *finite* distance before breing scattered or obsorbed and reimitted.
Ultimately the temperature of dust in space is determined by the number of photons (total lumens) striking a dust particle, and it's a *finite* amount, regardless of the size of the universe.
The only way the whole universe could be an infinite temperature is for every square inch of the whole universe to be contained inside of a infinitely dense, infinite temperature sun. In our *actual* universe, suns have a *limited* temperature, they have a limited size, they emit a *limited* number of photons at those limited temperatures, and their light travels a *limited* distance before being deflected, absorbed or blocked in some way. You're grossly ignoring the key differences between what would be required to sustain infinite temperature and what's actually possible in the *real* universe.
No, suns are not infinite temperatures to begin with.Stars would of course block starlight from other stars, but if energy is conserved then the temperature everywhere would be infinite,
False. See Scott's explanation. The distance light can travel is ultimately *finite*, not infinite.flux etc would be infinite in every direction,
That's not even remotely possible.no matter what the average temperature of stars.
You're still ignoring the whole "tired light" aspect by the way. Again, redshift is *observed* so the there is no possibility of light from infinitely distance suns ever reaching Earth.This is based on the universe being in existence for eternity, ie light has come from infinity.
Of course it does. It's the same basic issue. The light from *finite* temperature suns can only travel so far before it becomes irrelevant tin terms of luminosity or temperature.The visibility of individual stars by the eye doesn't change this.
You're grossly distorting the problem by ignoring several key points which I've cited above. The suns are a finite temperature. Only finite number of stars will be capable of producing photons that will reach Earth. The *average density* of starlight ultimately determines temperature, and they can only be *finite* inside of our physical universe due to the distances between stars, the inverse square laws, and the scattering/absorbing effects of dust in space.
