I have been to wikipedia about intensity of light, and there are at least 20 different ways to classify it. So I guess it boils down to the formula E = hf, which is the energy of a single photon. Now past gamma rays, is there a maximum frequency, hence energy of a photon? How does what we can create in labs compare to what exists in outer space?

I'll suggest GRB 110918A, which had a peak luminosity of $L_{iso} = 4.7 × 10^{47}$ Watts. That a ten to the forty-seven - it isn't a typo.

  • If E = hf, can you calculate the frequency from this em source? – Paul FitzSimons Oct 27 '17 at 20:57

    No becaue it wasn't a single photon. – JMLCarter Oct 27 '17 at 21:00
  • To put this answer in an intuitive perspective, our Sun is a bit too light to ever go supernova, but if it did, then its explosion a hundred million miles away, here on Earth would be a billion times brighter that a hydrogen bomb exploding next to one's face. – safesphere Oct 28 '17 at 03:59
  • JMLCarter --- Is there a maximum frequency of a photon? And how does this relate to Wattage? – Paul FitzSimons Oct 29 '17 at 18:19
  • Not really. Although it gets complicated, here https://physics.stackexchange.com/questions/341456/what-is-the-maximum-temperature-for-a-photon This question is on hold now. – JMLCarter Oct 29 '17 at 19:09
