Oh it is you! I didn’t make the connection quickly this time.

I always imagine a meeting of theoritical and particle physicist to be much like a tea party at Carroll's , with the mad hatter at the head, everyone spouting the most crazy ideas and a cloud of numbers and magic symbols hanging above

This depends. Those meetings can sometimes be quite… errrhh well… lively ;)

But the way i see it most of it isn't proven

This is exactly the problem with dark matter: it works extremely well, but somehow we are missing the direct proof of its existence.

I had a small question too, btw sensei @lemouth, it says somewhere inthere in one of the wikipedias that, according to Hawking, primordial black holes can be as small as (that means mass i assume) 10-8 10 to the minues eight ? i

You are missing the units. A number without a unit has no meaning ;)

Indeed, primordial black holes can be as light as 10^-8 kg. But those black holes are not there anymore today, because whilst black holes accrete matter (i.e. they grow), they also evaporate (i.e. they shrink). Small black holes shrink faster than they grow. Inversely, large black holes grow faster than they shrink. In other words, light black holes have fully evaporated since a long long time. 10¹¹ kg is the limit: anything lighter is totally gone today.

For the witness stuff: the easiest is to use proxy: one account votes and all the others follow. In any case, thanks for supporting stem.witness. But why do you need so many accounts?
