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

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.

It's not that you "lose" it. It's just that it's in different units. And is makes sense that free space should have a permeability of unity, as opposed to some clunky number with 5 different base units.
