Mini black holes that look like atoms could pass through Earth daily
It's been a while since I've read anything new about mini black holes, but the paper above suggesting the type that may comprise a large part of dark matter in the universe was interesting. They argue that maybe they don't evaporate in Hawking Radiation, but have matter orbiting them sort of in the way that atoms have electrons around them. They do not consider that they would be dangerous at all.
I also saw recently that Adam Helfer, who wrote a paper years ago in which he questioned whether Hawking Radiation really existed (thereby gaining some prominence in sites concerned about whether potential mini black holes from the LHC could be dangerous) has another paper out called Black Holes Reconsidered. He still questions our understanding of Hawking Radiation, and also notes that, while they seem possible in certain scenarios, no one really knows what a naked singularity would look like.
Uncertainties continue in physics, then.
no one really knows what a naked singularity would look like.
ReplyDeleteWell it would look like a singularity, only without clothes.
I don't know what a singularity would look like, but very singular, I'd imagine.
