Discussion Overview

The discussion revolves around the hypothetical scenario of space travel involving warping space and its potential effects on time. Participants explore the relationship between space and time in the context of relativistic travel, particularly at speeds approaching the speed of light, and how these factors might influence the perception of time aboard a spacecraft compared to an observer on Earth.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether warping space would also warp time, suggesting that both effects might combine when traveling at high speeds.
  • Another participant emphasizes that space and time are interconnected, referencing the concept of space-time in relativity and suggesting that discussions should be grounded in Einstein's field equations.
  • A participant provides a specific example involving a journey of 200 light years, discussing how time dilation and length contraction would apply, indicating that measurements differ between observers on Earth and those aboard the ship.
  • Clarifications are made regarding the distances and times as perceived by different observers, with one participant correcting their earlier statements about the measurements taken aboard the ship versus those on Earth.

Areas of Agreement / Disagreement

Participants express differing levels of understanding and approaches to the topic, with some focusing on the theoretical implications of space-time while others provide specific calculations. There is no consensus on the implications of warping space on time, and the discussion remains unresolved regarding the hypothetical nature of the technology involved.

Contextual Notes

Some participants express a desire for simpler explanations, indicating varying levels of familiarity with the underlying physics concepts. The discussion also highlights the speculative nature of the scenario, as current technology does not allow for such travel.

Okay so I have a completely sci - fi question.
Lets say we build something that warps space to travel a shorter distance, would time be warped aswell?
Lets say this hypothetical ship travels at 99% of the speed of light without the warp, then time would be diffrent both because of the speed and warping of space, hypotheticly do you think they would both add upp? why and why not ? Example of what I am thinking of. Let's say the destination is 200 light years away. for the ship to reach its destination takes about 250 solar years. Now if we have a clock on the ship, how many years would it show?

Keep in mind I have a very rudimentary understanding of physics so if you could break it down into layman's terms I would very much appreciate it.

First of all, this is a science forum and not a scifi forum.

Space and time are not independent. What is being curved in relativity is space-time. Any further discussion must be based on an actual solution to Einstein's field equations. You cannot discuss this simply using words as it is prone to misunderstandings and imprecise statements.

Then do not mark your thread "A". Doing so indicates you expect an answer accessible to someone with an understanding of the subject at graduate student level or higher. I am going to relabel the thread as "B" level.

I assume you mean 200 light years as measured by someone resting on Earth? And relative to Earth the ship is traveling at a speed of 0.8 c so that it takes 250 years to reach its destination, again as measured by someone at rest on Earth. To someone aboard the ship, the distance would be 120 light years, so the trip would take 150 years.

Measurements taken aboard the ship indicate that the distance is 120. Measurements taken on Earth indicate the distance is 200. When we compare the two we say the length is contracted from 200 to 120.

Measurements taken on Earth indicate the time is 250. Measurements taken on Earth indicate the time is 150. When we compare the two we say that the time is dilated from 150 to 250.

The only thing sci-fi about this scenario is that we we don't have the technology to build ships that travel this fast. But if we did, this is what science tells us would happen.

Oops! I just noticed a big typo in my previous message. Let me correct it ...
