Uniform background dust of plank mass black holes.

[Spinnor]

Say our early Universe had a significant fraction of its mass in the form of a uniform dust of plank mass black holes, along with the visible matter of our present universe. How might you figure such a dust would evolve in our early universe to our present epoch? Would such a dust clump just like ordinary matter? How would such dust effect spacecraft or humans? Would a plank mass black hole hurt if it passed through me?

Thanks for any help!

They'd evaporate instantly.

Let us assume they don't, it is just conjecture they do? We have never seen a black hole evaporate, maybe they don't?

Thanks for your reply!

What would these black holes be made of?

I was more interested in their dynamics, so let's just say they existed in the past and figure out their dynamics past and present.

Thanks!
