If we one day find away of refuelling satellites in the orbit GEO will that be able to extend the life of the satellite to lets say 100 to 150 years?

If you look towards the origin of The Big Bang then in theory you are looking back in time. So, if you turn 180 degrees, would you be looking into the future?

Assuming only radial variations in planetary density, it can be shown that if a planet has a radius R, then to an observer at a distance r(> R) from the centre of the planet, all mass within the planet acts as if it is concentrated at the planet's centre. The escape velocity of an object placed in the gravitational field of a planet is given by Vescape = radical p2GM/r, where M is the total mass of the planet and G is the gravitational constant. Calculate the escape velocity at the Earth's surface. How does this compare to the escape velocity 100 km above the Earth's surface? How does that last figure compare to the velocity of a satellite in a circular orbit 100 km above the Earth's surface?

So if you cross the IDL wesward, you gain a day. But if you go to the north pole and start circling it a thousand times going west every time you cross the IDL, will you gain 1000 days?

Due to the Earth's rotation, surface objects are actually moving with high velocities. What
fraction of the Earth's escape velocity is obtained by an object placed at the Earth's equator?
Ignoring weather as a factor, is it better to launch a rocket to the Moon from the equator or
a pole? Does direction matter? Explain your answer.

What if our universe was actually a tiny cell in another beings body, and wars being fought here were a way it fights off infection....could you imagine how large the being must be and what kind of place does it live

What's the cheapest telescope with a camera mount? I want to put a Fujifilm camera on a telescope. Fujifilm cameras work with Nikon lenses. It's an SLR obviously. I don't have any specific needs. I want want something fun to play with so I want to spend as little as possible.
