Hello I have a question (well its 2 questions)... I'm not hugely knowledged on the subject so i tend to question things in a more ignorant way but i wanted to know two things: Firstly, how do astronomers weight a galaxy at an accurate level to be confident enough to say there is more stuff...

I don't like to work with JS libraries, its simple enough to animate its just working out the equation - i suck at maths ! :) As for using Hohmann transfer orbits, what initial values must one know in order to use those equations? It seems to require gravitational parameters which i am not...

Hey I've been trying to make a basic animation which involves launching a spaceship from one planet to another. Both planets orbit at different rates from the star with fixed speeds. The spaceship also has a fixed speed from start to finish. What i don't understand is how you measure...

I can't see there being a need for it on a home computer for a company to ever invest in selling such tech.

That person failed to realize that higher end spec results in a hotter temperature, there is a limit to silicon computers.

Its a pre-render as are most teaser trailers for games. You won't get live rendering on games like that for another 5 to 10 years. Although that might be debatable. And in 10 years is only if its commercially worth while.

You forget land that is not suitable can be changed to be suitable with the use of man made greenhouses... Take Spain for example most of the land is dry semi - desert yet they converted ton of it to greenhouses so much infact you can see it from space its larger than a city:

Potato has a very low protein level, and we need that to live... so you would probably die if you only eat potato.

How does it effect itself? If gravity effects energy and gravity can have energy, wouldn't there be a infinite space curve like a black hole only not effected by mass in a small area but rather - itself.

Would curved space time have potential energy in same way a spring is just waiting to be relased by the release of the matter in space time? I ask because if gravity effects everything with energy, that would then mean it would effect itself which we know gravity doesn't effect gravity.

Do scientists believe absolute zero cannot be achieved then ? Or does it violate some physical law that we believe in =/ They always mention about the universe having a big freeze but they don't mention how cold it could theoretically get.

So absolute zero is impossible no matter how long the universe cools for ?

HeyI was wondering - is it physically impossible to make something absolute zero and then measure it to check if it was? I often read that we bring things down to "close to absolute zero" but it never is the full way. Is it because if human or electronic device, which ever it was that tried to...

Great site Chiral!

EDIT: So we have no real explanation how their spins become set instantly regardless of distance between them upon a measurement of either, or both??
