      Not really sure since my knowledge on black holes is not extensive and it could be and it will definitely be exciting phenomenon 🙂

      Eeek – you got me!! – astrology really isn’t my thing. Laurence, Jack – any ideas? I could Google it, but that would be obvious!!! You have to be careful what you read on the internet – anyone can write any old rubbish and pass it off as “fact”.

      I think it’s hard to believe in any hypothesis that we can’t test or measure. We have some measurements of black holes, so we can have some confidence that they exist. White holes are a very strange idea and we have no measurements of anything that looks like a white hole… but that doesn’t mean they can’t exist – it just means we have to keep looking for evidence! 🙂

      I gave another answer about how we know black holes exist here 🙂

      Hi, I was wondering what is a black hole and also how are scientists sure that it exists?
