Yes to both questions. For your 1st question, all motion by definition is relative because there is NO abosulte reference frame that you can point to and say that place is never moving. Hence, everything has to be is in motion with respect to everything else.

Our galaxy is (1) rotating about a large cluster of galaxies called the "Local Group", (2) on a collision course with the Andromeda Galazy, (3) moving away from nearly all other galaxies due to the expansion of the Universe from the Big Bang.

I presume your asking is everything in motion on this world and subsequently are the galaxies in motion?

Everything does indeed move relative to each other. To quote Einstein "everything is relative" for example a train heading north at 30 MPH (miles per hour) one could say that the train was moving north relative to the earth or that the earth was moving south relative to the train.

There are many contradictions when talking about this lack of absolute space (and time) the main theory which proves this would be Einsteins on general relativity.

So in short yes in this world everything is said to be moving relative to each other - and in the universe as a whole. The galaxies are also in motion (caused by the expanding universe).

Also discovered in the 1920's by scientists when they examined the red shift of these galaxies was that the vast majority of them were in fact moving away from us. Edwin hubble discovered in 1929 that their velocity is directly proportional to how far they are away (the farther their getting the faster they are moving away).

All planet revolve around the sun. I believe that everything in space is moving. Meteors are parts of planets that were broken off from being hit by something like another meteor. There is constant moving up there. Ever watch the Science channel? You really learn a lot from that. I love it.

No, the Earth is the centre of the universe and is fixed in place. All things revolve around the Earth.

If only one object in the universe was in motion then automatically all other objects in the universe would be in motion relative to that object.

I am not in motion. The universe revolves around me.

Ooops. There is no fixed point in space/time that the universe revolves around. So, everything is in motion in at least one of the four dimensions in 'normal' space/time.

Every object in the space is in motion. That is how they survive from other objects gravity. By moving usually orbitting around a bigger object than they are , they escape the gravity.

If you take celestial look Yes everything is in motion but not necessarily with respect to one another.
As you are in m otion to someone sitting on moon but to the person aside you you are not in motion.
Also all galxies are in motion.

yes everything is moving no matter how big or small it is. and acutually in about 5 billion years our galxcy is going to colide with andromida, now i suck at spell but yes we are all moving and were going to crash in to another galaxy

Stupid question of the hour. Clue: You probably think your spelling looks cool...the reality is it makes you look dumb.

dude, maybe you should focus your time on learning how to write, instead of asking dumb questions.
