How fast are we moving when we're sitting down?

The earth rotates on its axis, it also rotates about the sun, the milky way galaxy is moving, etc.
So, how fast are we moving when we are sitting down?

In relation to things on the opposite side of the universe, in areas where we'll never see the light from due to the rate of the expansion of the universe, you're moving at nearly the speed of light.

You may want to sit down for this... on second thought, you are still moving too fast so just lay down on the floor.

I got 8. Show your work please.

So which direction do I run to move faster than light?

[FONT=Verdana, Arial, Helvetica, sans-serif]How fast do we have to move to make it around the Milky Way in one galactic year? It's a huge circle, and the speed with which the Sun has to move is an astounding 483,000 miles per hour (792,000 km/hr)! The Earth, anchored to the Sun by gravity, follows along at the same fantastic speed.
[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif][FONT=Verdana, Arial, Helvetica, sans-serif]And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)! We are moving roughly in the direction on the sky that is defined by the constellations of Leo and Virgo. Although the reasons for this motion are not fully understood, astronomers believe that there is a huge concentration of matter in this direction.[/FONT][/FONT]

Let me put it this way: The gravitational interaction between the mass making up your body and the mass making up the earth is so significant, that velocity relative to anything else is quite pointless.

Relative to your body heat (IR radiation), you are moving at the speed of light (in air).
That speed is not what will kill you though.
Speeds that are relevant: Velocity vectors of near earth objects relative to Earth. Velocity of you relative to near-you objects.

For all we know, our bubble of space-time actually "resides" within something else, and may even have a motion itself.

In conclusion: Aliens.

Motion is relative. Your speed is only relative to your distance from something else.

Earth is rotating. Earth is orbiting. The solar system is orbiting the center of the Milky Way galaxy. The galaxy is moving through space along with other galaxies. Galactic clusters / superclusters are also moving, relative to each other.

Damn people. The Earth is the center of the universe. WE are NOT moving...everything else is moving around us.

Not a valid question unless you say with respect to something, or in which frame of reference. In your frame of reference you aren't moving, in one frame of reference you are moving at one speed, in another you are moving at a different speed. There is no such thing as absolute velocity, only relative.

So if you accelerate in opposite direction that the galaxy is going and start going -1.3 million miles per hour, does time get faster or slower for you relative to earth?

Relative velocity is the only thing that matters, if you are going 1.3 million mph relative to earth. All you need to do is calculate time dilation. To you the earth time will be moving slower, to the earth your time will be moving slower.

Monty Python sing about this in the galaxy song although I suspect that they just made up their numbers.
