Black holes are one of the biggest mysteries in the entire universe (that we know of) although we believe we know how they are created; we have never actually seen one.
Well, how could we? It's pretty hard to inspect something that is so densely packed with matter even light can't escape!
All we have managed to see are particle jets erupting from black holes and intense x-ray flares thought to be caused by a black hole devouring a star. But we haven’t seen the hole itself. We can’t.
In fact, we don't really know much about them at all, all we do know for sure is that they REALLY suck!
So if you're a bit of a space geek, or even just appreciate a good ole' geeky pun when you see one, check out our range of funny science tees!
