Is the Universe made for life? Spoiler: NO!

Nope, the Universe is less than inhospitable: it is outright dangerous, killing every living thing it can.

Black holes are a sure thing, but white holes? They do, somehow, exist!

Black holes are singularities in space and time that can eat up a lot of matter. Theoretically they could eat up the entire Universe and still want more. Now comes the interesting bit: if you would to turn the time backwards those black holes would expel the matter back into the Universe. Those would be […]
