A small mathematical recall: There is the so called Fourier transform, it 
turns a space variable into a time one and vice versa.
If we ask what is the distance to the nearest civilization today, the Fourier 
transform answer is: It is at a distance in light years equal to the time 
between two related civilizations on Earth. Now, we are the fist civilization 
here, so, if the human species was wipped out, we can't know how time it 
would take for evolution to cook another technological species. On the other 
hand if we had lived 65 millions years ago, we would have been wipped out by 
the meteorite catastrophe who destroyed the dinos. So that, our best gues is 
65 000 000 yrs between two civilizations. So the nearest E.T. technology 
today must be something as 65 000 000 lys aways, this is beyond the limit of 
our Galaxy, even beyond the limits of the super amas on the border of which 
we stand.  So it is natural that we have no visitors from space, the Fermi 
paradox is only a paradox for sci fi where each star has a set of planets and 
each planet an advanced form of life.

Not so, A 850 bits quantum computer could simulate in a single computing 
round the full observable Universe for 10 billions years down to the Planck's 
scale (1.6 x 10^-33 cm) with a time frame resolution equal to a Planck's time 
(near 10^-43 second).

I'll write in another message about pulse quantum computing with trillions 
bits and beyond.

I think we don't live in a simulation, not because it is not possible but 
because we can't produce it now. I think nobody else has any interest to put 
us in a simulation.

There is the issue of simulation of simulation... This may be a possibility 
with string theories (physicists like to write it theory). A natural string 
is open ended, it is infinite at high energy but shrink to near the Planck's 
length at lower ones. These strings expand in 11 dimensions if they carry 
half integer elementary space "unit" and 26 dim. if elementary space is 
described by integer values. For any other dimensional values, smaller or 
larger, the string form loops and in each loop is a loop and so on... This is 
known as ghosts. There are some hint we don't live in a ghost Universe, if it 
turned that we are in a loop based Universe, then there would be an infinite 
set of Universe above and under us. At an infinite scale above us here would 
be a 11/26 dimensions Universe with no loop outside a very small domain. that 
small domain would be the place for the infinite set of ghost simulations.
