Good course, I don’t know that white holes still being a posibility. I found this paper about white holes, it is also written by Carlo Roveli: https://arxiv.org/pdf/1802.04264.pdf ; it is very interesting, talks about how a white and a black hole are indistinguishable from the outside.
It’s a little hard to understand because of math but it’s very good.-
Thank you for the link, I’m really interested in white holes. I think they are key for understanding quantum gravity and I even believe our Big Bang could be one: it has a singularity in the past and you’d need to travel back in time to enter it, the exact opposite of a black hole which has a singularity in the future and you’d need to travel back in time to exit it. Not only that but a black hole is “maximum entropy” while our universe started from very low entropy – maybe a white hole’s property is to have low entropy, just the opposite of a black hole. I wish more scientists would study black holes seriously as I think they hide in their math something big.
