Hawking radiation has never been detected because the temperature of a typical black hole is miniscule. Using the formula, the Hawking temperature of a solar mass black hole is about 0.00000006 Kelvin.pic.twitter.com/l7QseBt1oa

For those who are wondering, this is the equation in "natural" unitspic.twitter.com/AkjDiAgr0J
Very elegant! Natural units are rather "un-natural", they probably obscure physical reality, otherwise we would have been able to make sense of our mathematical theories. Also we should believe more in analogue gravity, there, Hawking radiation, will soon be observed...
They’re actually the most natural system you could use.. they’re the only system that allows time to be rotated into space (Lorentz transform) using SI is like measure horizontal and vertical distance in different units
Setting h =1, I have little objection, the rest of the constants I am not sure. Anyway, time is different from space (arrow of time), what is good to change the direction? (Do I get your point?...)
So given that one can be rotated into the other by relative motion, it only makes sense to measure them in the same units. As for the arrow of time, no units will help you resolve this. We just take it as fact.
Thanks, I don't object of course relativity of motion. I do believe that space and time should be measured with the SAME unit. The point I want to make is that by setting for example c=1 numerically and unit like you loose information regarding the electr. perm of vacuum.
Also transforming space into time by relative motion, bothers me, (space is a two way street, time one way) but then and what resolves I think the issue is that special relativity is an approximation to reality, there is always a gravitational field. What do you think?
There actually exist solutions to Einstein's field equations that completely swap space and time, eg inside a black hole. You can only move one direction but your time direction is now bidirectional. 1/2
