Remnants From the Early Universe. Primordial Black Holes
Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, you’d still end up at the singularity.
Astronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well.
But there’s a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter.
Primordial black holes.

In case you missed it, I had an absolutely fascinating conversation with Scott Gaudi about the HabEx telescope.

The universe appears to be around 13.8 billion years old. What is the logic behind saying that the size of the universe if potentially infinite? If we know the age of the universe and we know the speed of light, aren't we pretty sure of the size? Does the infinite universe rely on the multiverse concept. But even then, there may be untold zillions of universes, but not an infinite number?
