Are You Not Moving?

Are you sure?

As you sit unmoving in a chair, you are probably moving about 750 miles per hour as the Earth rotates.  More if you are near the equator, less if you are closer to the poles.

But then the Earth is in orbit around the Sun.  That has you moving at about 67,000 miles per hour.

The sun is part of The Milky Way galaxy.  The Milky Way rotates at about 540,000 miles per hour in the main body of stars.

Our Milky Way galaxy is part of a local cluster of galaxies moving generally along together at higher speeds, and the local cluster is part of a supercluster moving faster than the local cluster, etc.

You are moving at something like a million miles per hour.  It gets worse than THAT but I'll spare you...  And you feel like you are sitting still.  That's what gravity does.

And yet gravity is weak.  You can easily lift a brick against the full force of the gravity of the entire planet!  The human record seems to be 1,102.3 pounds of deadlift (just off the floor).

So gravity is weak, and we are moving at about 1 million miles per hour...  Ever wonder what keeps us on the Erth surface and just not jumping away?  LOL!
