Space question?

Question

If the Earth and is moving through space then that would mean we are never in the same "space" twice right? I hope my question is clear enough.

Answer 1

The Earth is moving around the sun. The sun is moving around the galaxy. The galaxy is moving through the Universe. The Universe is, arguably, endless. The odds of the Earth ever being in the same "space" twice: Infinity.

Answer 2

Technically,you are correct,because the earth is moving along with the milky way galaxy away from the point where the big bang occured,now if it's just in relation with our own galaxy,then we go around the center and will eventualy come to the same spot again,though it takes hundreds of millions of years to do so,

Answer 3

That's true. Even though the Earth is moving (roughly) in a circle, the Sun is moving even faster than Earth, so the spot where Earth was last year gets left behind. The Sun is also moving (roughly) in a circle, but it will never get exactly to the spot it was in before. Even if it did, the Milky Way is moving, so the Sun will move with it. The Milky Way is moving too, and its motion is more like a straight line. Certainly more complicated than just a circle. Bottom line: we will never be back at this same spot again.

Answer 4

if you asked einstein this question he would probably raise an eyebrow at you. According to him, there is no such thing as absolute space. (similar to time being relative to observers, space is the same way)

heres his example:
2 observers, one on a train moving down the tracks, the other standing next to the tracks watching the train move. To the first observer, a ping pong ball bouncing on the train would appear to him to be bouncing in exactly the same spot each time. To the the second observer, the ping pong ball is making arcs down the tracks, bouncing every 30 feet or so. Now imagine your the first observer and cant see beyond the edge of the train. you will never be able to tell exactly where the ping pong ball is bouncing, even if you could see beyone the train you could hardly suspect that you were contained within yet another moving system. which intern is part of another moving system. thats relativity. Same with time, two observers wont necessarly agree on what time specific events happened, yet neither will be wrong.

Answer 5

I'd say since the universe is expanding, our galaxy is "probably" moving away from the center. so if our galaxy keeps moving, earth goes with it. these objects rarely go backwards. the can be slung all about with a strong enough gravitiational pull, but chances of heading in the oppsite direction is slim to none.

I'd say we have a 1 in a billion billion billion chance of retracing our steps

Answer 6

Ah, yes. This would be a correct statement. We, earth, are in motion in our own solar system. We are also part of a larger system, our galaxy. And then outside of that we are part of the entire stellar system. And if what current science has told us IS true. Then we are moving away from the location of the Big Bang and therefore never quit occupy the same space twice. I hope my answer makes sense.

Answer 7

Yes.
