SUMMARY

This discussion centers on the theoretical implications of wormhole travel and its potential to facilitate faster-than-light (FTL) travel. Participants clarify that wormholes do not enable FTL travel in the traditional sense; rather, they provide a shortcut through spacetime, allowing for quicker travel between two points without exceeding the speed of light. The conversation also highlights the challenges of time travel paradoxes associated with wormhole use, emphasizing that while wormholes may shorten distances, they do not alter the fundamental speed of light.

PREREQUISITES
  • Understanding of general relativity and spacetime concepts
  • Familiarity with the theoretical framework of wormholes
  • Knowledge of time travel paradoxes in physics
  • Basic grasp of light speed limitations in physics
NEXT STEPS
  • Research the mathematical models of wormholes in general relativity
  • Explore the implications of wormhole travel on causality and time travel paradoxes
  • Investigate current scientific theories on the feasibility of creating wormholes
  • Study the concept of spacetime and its relationship with light speed
USEFUL FOR

Physicists, science fiction writers, and anyone interested in advanced theoretical physics, particularly those exploring concepts of wormholes and their implications for travel and time.

When a wormhole opens, if each side of space is equally stretched to meet each other. Then wouldn't it be possible to only go halfway through the wormhole, close it and allow the opposite side of space you're trying to reach, "normalize" and wouldn't the space on the side you've traveled to that "normalized" return to itself faster than the speed of light allowing for faster than light speed travelling?

That is not a good description.

If wormholes are possible, they allow you to reach some destination faster than light would need for the regular trip (without wormhole). There is no need to close a wormhole or whatever. The wormhole itself provides a shorter connection. You never travel faster than light - you just take a shorter connection. Light going through the wormhole as well would still be faster than you.

Also, if wormholes are possible, it is nearly impossible to avoid time travel paradoxes.

What I was trying to say was, If I used my incredible technology to open a wormhole to travel to you, in which you are several thousand light years away. At the same time, you opened a worm hole allowing the worm hole to be opened faster. Then once I travel technically to you, the space you were controlling, turn my technology off, then turn off your tech. Your side of space would return to normal in half the time since your technology only had to establish the connection half way.

That doesn't make sense.
Also, while we do not have wormhole generators for a reliable time estimate, the typical timescale for the process would be the size divided by the speed of light - less than a microsecond for all practical purposes. There is no need to speed up a process that takes a microsecond.
