How would the world appear at near c?

If you were on a rocket ship that orbited Earth at near c, what would it be like? At 1000km high, orbiting 40 times per second, you'd have a velocity of .84c.

What would, for instance, a radio broadcast emitted from all points of the Earth simultaneously (with respect to the Earth) sound like? What if you had a video camera that recorded, at 40 frames per second, someone walking down the street or car driving (on earth) 100km/hr. Would all this be going in seemingly fast forward?

If you sent a signal to Earth each one of your seconds, would it be received slower than once per second?

Input appreciated.

Time on Earth would appear to be running at twice speed for you. Alternatively you would be moving at half speed to an observer on Earth.

Blows my mind.

How about contraction? Would the Earth appear contracted along the axis of my rotation, and therefore be elliptical in shape (taller than it is wide)?

For a discussionm of some effects during inertial motion:

Have a look at http://www.edu-observatory.org/physi...eadlights.html

Rotational acceleration would likely complicate things a bit...
