In Focus: Black Holes

Black holes are an Interesting topic to talk about. But if I would ask you what do you know about black holes, you'd probably tell me that you know there are massive "holes" that suck in matter, and even light can't escape. This is what I would think the usual understanding of black holes is, but it is way more complex.

What are Black Holes?

Black holes are basically a gravitational well that alters space-time in such a way that if light falls into that well, it can't escape (img. 1). Black Holes usually form from collapsed stars, and the biggest are located at the centers of galaxies like the Milky Way.

As a matter of fact, you may not see the iconic rings as you can see on the cover image, and you may wonder why. This is so because it just so happens that this image was taken from above, where you just see the rings (like the ones on Saturn just made differently), but the ring above and below are actually just an illusion caused by the way black holes are built, as you usually see a sort of reflection of the ring. (Greatly explained in the video "What if I fell into a Black Hole," Broadcasting until the 24th of April 2026).

Teleportation Using Black Holes

Some people believe that black holes are linked to a white hole (the opposite of a Black hole) and that when you travel into a black hole, you go through a wormhole and get spat out on the other side by a white hole. Although this might be real, it is mostly impossible and a wrong interpretation of Einstein-Rosen bridges and his theory of relativity. And if this way of teleportation were possible, you would just be stuck there forever because the wormhole would have collapsed because of gravity.
