Because the Earth is round, does that mean that nothing straight is actually straight? Lets say that somehow a perfectly straight 200,000,000,000,000 mile ruler was made in space. If it was brought down to Earth, would it be like a ruler on a ball? Would only the middle be touching and everything else in the air?

I've been viewing photos from Australian mountains and I noticed that local trees are green even in winter. I hate bare trees, they make everything look so much worse! Can't we plant those evergreen trees in Europe?
Take a look:

I've always wondered how people like einstein, bell, ford etc,
Come up with the concept of an idea that isnt was'nt real and produce a working model of their idea like the car or phone.

Now we have concepts like teleportation. Are people like this born to invent?

if an object was orbiting around a star and the star suddenly dissapered would the planet instantly start moving tangent to its orbit or would it continue to orbit until the light from the star reached the planet. i guess what im asking is does gravity travel in waves at a constant speed like light or does it take instantanious effect? and if it takes an instantanious effect then wouldnt it be possible that gravity is pulling on us from objects that we cant see because they are too far away to see?

If the cone formed has an angle a find the rate of change of volume with respect to height? If the height is changing at 2cms per minute, what volume of sand is falling from the hopper when the height of the cone is 3 meters? (the volume of a cone is (1/3)pie^2h where h is the height and r is the radius)
