I know this question may be a bit vague, and probably needs better wording, but I struggle to rephrase it. What is the effect that a larger planet eg. Jupiter has on a smaller nearby planet eg. Mars? This question is based mainly on the orbital path of both planets, how is it influenced?

one other possibility is that when future time travellers traveled back in time, they actually went to a parallel universe and met Stephen Hawking there and not in our universe. We will thus never know.

go to youtube and type in "CD hovercraft".

the CD will not blow away from the ground because the moving air underneath the CD forms a sort of vacuum which "clings"the CD to the ground, but lifts it off the ground enough so to minimalize the froction between the CD and the gound. with this in mind you can attach a nozzle that splits the...

ok, but that does not really answer my question. how does it work.

why does the colour of the sticker on the pizza box change when you apply heat to it?

Idea: attach the balloon to a CD so that the outlet of the balloon blows through the hole of the CD. Blow up the balloon, place the CD flat on a smooth surface (with the balloon facing upwards) and let loose. It's like a mini hovercraft.

How is it possible to see the light path of a green laser pointer?

Just look at the sun, it is a continuous proof of E=mc^2.

http://www.sciencedaily.com/releases/2009/09/090903163725.htm I found this article while reading up about magnetic monopoles. It says the they have observed monopoles, I went to my physics lecturer with this and she told me that is a false article and that monopoles are still only theoretic...

If I want to build one, what will be the best way to approach the project? What skills would be required?

"backyard" radiotelescope I would like to know if it is possible to build a "simple" radiotelescope. It doesn't have to be powerfull, just a small project.

Search "A brief history of myne". It is a short piece that Stephen Hawking wrote about himself.

Forgive my mistakes. I typed that post from my cell phone and can't use the lower case at the beginning of each sentence. As for the forgotten t after Vi...that is just unforgivable, sorry.

Take the equation : x=Vi + 1/2(gt^2). X = distance Vi = initial velocity G = gravitational acceleration (10 m/s^2) T = time The mass of the weights will have no effect on the velocity with which the weight hits the ground. Your initial velocity will be 0 bacause the weight will be let...
