Could Traveling at Near-Light Speed Create Black Holes?

Click For Summary

Discussion Overview

The discussion revolves around the implications of traveling at near-light speed and whether this could lead to the creation of black holes due to length contraction effects. Participants explore theoretical aspects of special relativity, particularly focusing on length contraction, and its perceived effects on massive objects like stars.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants propose that traveling at .99999999 percent the speed of light would cause a star with sufficient mass to contract in the observer's frame of reference, potentially leading to the formation of a black hole.
  • Others argue that this inference is incorrect, stating that length contraction does not imply that a star can be turned into a black hole simply by an observer's high-speed travel.
  • A participant mentions that a high-energy particle traveling near light speed past the sun would not affect the sun, suggesting that relativistic effects do not lead to black hole formation.
  • Questions are raised about the nature of length contraction, including whether it is "real" or merely a measurement artifact, and how it relates to the forces acting on objects at relativistic speeds.
  • Some participants express skepticism about the validity of the formulas used to describe these phenomena, suggesting misapplication or misunderstanding of the Lorentz transformations.
  • There is a discussion about the implications of length contraction on atomic and molecular scales, questioning whether physical dimensions actually shrink or if it is a matter of perspective.
  • Participants clarify that length contraction is a consequence of viewing a four-dimensional object from a three-dimensional perspective, and that the forces between atoms also transform under relativistic conditions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of length contraction or the validity of the formulas involved. Multiple competing views remain regarding the nature of length contraction and its effects on massive objects.

Contextual Notes

Some discussions highlight limitations in understanding the implications of relativistic effects, including the need for clarity on definitions and assumptions regarding length contraction and its physical reality.

Who May Find This Useful

This discussion may be of interest to those studying special relativity, theoretical physics, or anyone curious about the implications of high-speed travel on the nature of space and time.

Please get back on topic @Matt Fenwick Neither the discussion of Wikipedia nor the discussion of anyone's Nobel prize is relevant to this thread.

We just look at whether it makes accurate predictions.
And the myriad of following theories that build upon it that would be fundamentally misguided if it was not correct to high accuracy. In the case of SR, such theories include — among others — quantum electrodynamics which is one of the most (if not the most) numerically accurate theory to date. Arguing that relativity is fundamentally misguided is similar to arguing you can’t build a house with wood and stone.

No, you are wrong. No one light clock should be any more or less valid than another.

As a professional scientist, I can tell you that this is wrong. I do get some of my information from Wikipedia. I also write information on Wikipedia for others to use. I also quote Wikipedia to people on the internet as an easily accessible resource for them to use, regardless of where I originally got the information.

You are misinformed on multiple points in this thread including the value of Wikipedia, the experimental confirmation of the Lorentz transforms, and the predictions of relativity.

You came here to learn, or to argue with those who know way more than you?

Indeed. And this claim is incompatible with length contraction not existing - glad to see you starting to come round.

S.R. is fundamentally misguided. And you are the first person I have ever heard say quantum theory is based on S.R. Seems you are fundamentally misguided. Einstein did not get the Nobel prize for S.R. Matter of fact many physicists rejected it.

He said quantum electrodynamics, not quantum theory. Early quantum theory was non-relativistic, but quantum field theories (including quantum electrodynamics) are entirely based on a relativistic worldview.

This thread is closed for moderation.
In the meantime @Matt Fenwick should give https://web.physics.ucsb.edu/~mark/ms-qft-DRAFT.pdf (this because it is online and free and the errors in draft are inconsequential for present purposes) a try to understand the relation between quantum electrodynamics and SR - QED is fundamentally based on SR, just as Orodruin says.

It looks like the OP has left the building, so this thread will remain closed. Thanks all for trying to straighten out the OP's misconceptions.
