Can we travel back and forward in space?

Click For Summary

Discussion Overview

The discussion revolves around the concept of traveling back and forth in space, drawing parallels to time travel. Participants explore the implications of relative motion and the feasibility of reversing one's position in space, while also touching upon the nature of travel in relation to the movement of celestial bodies.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant asserts that traveling back in space is impossible, similar to time travel, due to the high velocities of celestial bodies and the nature of motion.
  • Another participant humorously questions the practicality of the claim by referencing everyday travel, suggesting a misunderstanding of the original point.
  • A third participant challenges the initial claim by implying a lack of understanding of "relative velocity."
  • There are multiple humorous and sarcastic responses that reflect confusion or disagreement with the initial assertions about space travel.

Areas of Agreement / Disagreement

Participants express disagreement regarding the feasibility of traveling back in space, with some questioning the validity of the initial claims and others responding with humor. No consensus is reached on the topic.

Contextual Notes

The discussion includes varying interpretations of motion and travel, with some participants seemingly misunderstanding the implications of the original statements. The context of relativity and motion is not fully explored, leading to potential gaps in understanding.

Who May Find This Useful

Individuals interested in concepts of motion, relativity, and the philosophical implications of space and time travel may find this discussion engaging.

Space travel is possible (or not) not more than time travel is.

Do you thing that you can travel back and forward in space? You may THINK that you can, but you can't.
We all travel with earth, and Earth travels with sun, and sun travels... etc.
The final velocity is too high to reach with any technology, so we can't cancel it or reverse it.
It's impossible to go back in space! As it is impossible to go back in time.

So:
- We ALL travel only forward in space and time.

- The small variances in our velocity is more noticeable in space than in time
(this is due to the very high speed the light has according to our perception).

- Forget about time traveling and think about space traveling first!

Any comment?

You mean that when I leave home to go to work in the morning, I can't go back?

I take it, then, that you have no idea what "relative velocity" means!
 
This is pretty much nonsense. It does not belong in the Relativity fourm, perhaps GD is a better place for it. Moved.

...what are you smoking, man?
 
You mean the sandwich I brought to work is stuck in the refrigerator forever? But I'm so hungry. I'll have to wait until I get home to eat.

Wait. I can't go home either. I'm doomed to roam the Earth for the rest of my life, without home or love. :(

You win this time, unidirectional, apparently 2-D Space.
 
No comprende.
