Radiation emitted in the vicinity of black holes could be used to measure distances of billions of light years, says TAU researcher.

Using radiation to measure distances is a general method in astronomy, but until now black holes have never been used to help measure these distances. By adding together measurements of the amount of energy being emitted from the vicinity of the black hole to the amount of radiation which reaches Earth, it’s possible to infer the distance to the black hole itself and the time in the history of the universe when the energy was emitted.

 

 

Sounds a bit complicated to me and with most things on this level, requires a certain amount of guess work.

I would have to agree with you on that one Mike.

I think the key word in that write up is "infer"
