RE: Can dark matter be made of black holes (or machos)?

in #steemstem7 years ago (edited)

Thank you, I dared to read and try to understand about this topic. :-)

Somehow it gives me creeps thinking of black holes and it eased me a bit to read that some of the black holes can evaporate and a certain amount just disappeared :-) to the others which don't, I hope they do not come near earth.

So, are there two theories about primordial black holes and not more?

What is fascinating you about this (dark;) matter? Do you see a future in humankind traveling space or is it just a theoretical interest of yours?

Sort:  

The big ones are those that do not evaporate. There is one of them at the center of the Milky Way, but no worries, it is far enough :)

There are many, explaining how they could be formed.

There is no way to use it for traveling (first we need to discover it). Personally, this is something I am working on. I have co-authored several scientific articles in dark matter :)

Thanks, @lemouth

Glad, that the one in the Milky Way stays at distance - I know, it is for sure a stupid question because I am in no way a sophisticated reader on this faculty. But do also "wormholes" exist? I am of course referring to Star Trek episodes which I love to watch and THEIR space is full of them. :-)

No, I meant in general - there is all this hype in space traveling (Elon Musk) to the Mars. If one would ask you to join a mission, would you go?

P.S. Can amateurs read what you were co-writing? Do you have a link?

Wormholes are on the side of theory at the moment. There is no experimental proof.

Ahh going to Mars (and traveling in space) is by no mean connected to what I do. I actually would skip going to Mars. Others can do it ;)

All my publications are open access but you may need some particle physics background to fully get them :p I can give you references in the chat.
