Is a Rocket at Light Speed Truly Infinite Mass?

Click For Summary

Discussion Overview

The discussion revolves around the concept of a rocket reaching light speed and the implications of mass becoming infinite, as presented in the book "The Crack In The Cosmic Egg." Participants explore the theoretical aspects of mass, acceleration, and the work required to achieve light speed, questioning the plausibility of the ideas presented in the book.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant summarizes the book's claim that a rocket at light speed has infinite mass, creating a gravity force field that could restart the universe.
  • Another participant expresses skepticism about the plausibility of the book's claims.
  • Some participants argue that it is impossible to describe an object with mass traveling at the speed of light within the framework of relativity, suggesting that any conclusions drawn from such scenarios are nonsensical.

Areas of Agreement / Disagreement

There is disagreement among participants regarding the plausibility of the book's claims and the implications of mass at light speed. Some participants reject the ideas outright, while others engage with the theoretical aspects.

Contextual Notes

Participants highlight the limitations of discussing mass at light speed within the context of relativity, indicating that assumptions about mass and acceleration may not hold in such scenarios.

I read some time ago a resume of the book the Crack In The Cosmic Egg and this is more or less what it told:

When a rocket acquires light speed its mass becomes infinite which creates a gravity force field that crunches all the universe making it restart.

Its argued that to propel a rocket to light speed you need infinite work but then your time is zero so let's check the equations:

Work=force by distance
Force=mass by acceleration
Acceleration=velocity by time

But time zero so velocity infinite so aceleration infinite so force infinite so work infinite

So how plausible do you think this book is?

If your description is accurate, not at all.

It's impossible to describe an object with mass traveling at the speed of light in relativity. So any conclusions drawn from relativity about what would happen if something with mass did travel at the speed of light are nonsense.

On these words of wisdom, thread closed.
