Reply to The Case for Callisto by MoreGull

Okay but, I like Ganymede’s name more. Although ngl this is the first time I’ve heard of Callisto and it’s kind of growing on me. Alright I’m in agreement with you.

I absolutely agree with the other comments about going for binoculars over a cheap scope. Go for binoculars with big objective lenses and don't go for huge magnification. While you want some magnification, what you really want is to get more light into your eyes. With binoculars like that, you should be able to see lots of interesting and beautiful things in the sky. You may be able to find an old pair in a second hand shop... Goodwill for instance?

As for telescopes, you won't find anything that won't frustrate you terribly for the kind of money you're talking about. I got a department store scope when I was a kid, and it just drove me nuts. You might look into making one. One of the popular telescope designs is called a "Dobsonian". It's a simple telescope, often made from cardboard tube and plywood, with a home-ground mirror. They are named after the guy who developed the design, John Dobson. He used to make these telescopes and take them out in San Francisco and show the sky to local kids. Sometimes, he'd give one away to an eager kid. He was a monk (if I remember right) and had to make them cheap.

Look around your area and see if there is an amateur astronomers' club around. If so, there are bound to be old codgers there who would be helpful with advise on getting into astronomy, what sort of equipment might be good, and how to make your own, if that sounds interesting.

Don't forget, by the way, that you don't have to have expensive equipment to get into star gazing. You just need at least one eye and clear skies. Although having a star chart with you (either printed or an app) would be a big help too. Binoculars and telescopes will show you more, but there is a lot to see just by looking up.

Reply to comment by ForTech45 in How to make a model of dark matter and energy? by Poise-on

>I think you misheard what that guy said, because the leading theory is still 100% an unknown subatomic particle, and I would hazard to guess that 90-95% of physicists in a field involving dark matter believe that it is just that— matter that only interacts with gravity, or interacts extremely weakly with the other known interactions.

Ah, well yes then, I suppose that is the leading theory. That was not however the theory he presented.

He did not speak directly to or for its existence, but he did speak about how many of the effects attributed to dark matter may well be explained through re-examination of the theory of general relativity itself.

He began the talk with a criticism of a lot of high energy physics and particle physics. The association may have been one I made on my own, but the implication seemed to be that this theory was an alternative to the subatomic particle theory.
