I'm still confused. The mirror or mirror segments are still mounted onto some metal truss frame, such that the telescope can be rotated and pointed,...
Wait, are you saying that starlight, the points of light, cause a significant thermal variation on that point of the mirror? That would be hard to...
In that case, can't some sort of heating system be applied? It wouldn't have to keep it very warm, just uniformly warm. Are observatories really so...
I see. I was afraid it might have something to do with how the glass is grinded and made into an accurate shape, like maybe that's more difficult...
I was just reading about some very large observatories being planned or under construction, and how these huge mirrors require up to 6 months to...
Not a bad point about carrying loads on the bike too insteada walking. But "not having to wait at all"??? You still have to wait...at cross streets,...

It's more than that. This is an instance of someone using a computer and the internet to...not only diss science...but also question why we should...
A long recharge time should not really be an issue for the average driver since you can just plug it in overnight (unless of course, you are a "lazy...
I forgot to add about the transition from straight up flight to parallel flight. There actually is no transition in g-forces. Assuming the mass is...
I think I finally figured it out. It happened as I was drawing the diagrams with acceleration arrows. I drew a point mass of 1,000 kg, a down arrow...
You guys make a good point that earth's g diminishes with distance , so it is not always 9.81 m/s/s. However, at orbital altitudes of around 300 km...
My intuition says yes because we are always feeling 1 g just sitting here, so a rocket ascending at say 1 g, has to feel 2 g right? But when does...
No i don't mean propulsion per se. I mean electric power for all systems in general, such as radios, computers, air pumps, etc. It could also include...
I need someone familiar with supercolliders, those things they use to smash matter and antimatter together, to help me explore this. On its...
No need to believe. Only need is to calculate. Frankly in reply, for someone who multiple times pleaded to do some calculations (okay it was at...
Found one: https://en.wikipedia.org/wiki/File:Orbit3.gif There are different points on Earth that do not have the same distance to the barycenter....
You totally lost me. You asked why doesn't a proton and electron annihilate each other. You said u meant electron and not anti-electron. So now I...
Because they're not opposite matter, so why would they annihilate? A proton and electron are both normal matter. Did you mean anti-electron? That...
Uh, so you're saying each point follows a circle around the barycenter, and that circle has constant radius? I don't disagree with that. But sure...
