I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Boron Zone. It has a range of scientists studying all different topics. Who gets the prize? YOU decide!
We have a lot of evidence that black holes exist. From the massive black hole at the centre of our galaxy (a million times heavier than the Sun) to smaller black holes orbited by stars, while we can’t see them directly, we can see their effects on the surrounding space.
White holes on the other hand have never been seen, and are only based on some clever mathematics. They might be out there, but we’ve never seen the evidence!

Definately one for Simon – pleased he’s on the team!

So something else that you might be interested in – there are areas of physics called “analogue gravity” which in a certain sense try to mimic the sorts of things predicted by Einstein’s theory of general relativity. My own area of ultra-cold gases contributes to this. In principle, you can set up a gaseous Bose-Einstein condensate such that it has acoustic “white holes” and “black holes” – that behave in the same manner as for gravity, but for sound. For example, this is a link to recent work on this:

The idea is that if we can find similar phenomena in other systems, we might learn a bit more about gravity, and in particular, quantum gravity (I think).

Im still learning about space 🙂 imascientist is first time I’ve heard of white holes
