About Deja Vu: Mass and travelling into an alternate universe.

Click For Summary

Discussion Overview

The discussion revolves around the portrayal of mass and time travel in the context of a science fiction movie featuring Denzel Washington. Participants explore the relationship between mass, energy, and the stability of wormholes as depicted in the film, questioning the underlying physics principles and their plausibility.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express skepticism about the scientific accuracy of the movie's depiction of wormholes and time travel, suggesting that the concept of mass affecting wormhole stability is fictional.
  • One participant questions the logic behind the assertion that too much mass or energy could destroy a wormhole, referencing the equation E=mc^2.
  • Another participant notes that the film's portrayal of time travel is more accurately described as travel to a similar universe rather than true time travel.
  • There is a discussion about the presence of an electromagnetic field in the movie, with participants seeking explanations for its relevance.
  • Some participants highlight the tendency of filmmakers to create fictional physics principles, questioning the need for logical consistency in science fiction narratives.

Areas of Agreement / Disagreement

Participants generally agree that the scientific principles in the movie are not grounded in established physics, but multiple views remain regarding the implications of mass on wormhole stability and the nature of the travel depicted in the film.

Contextual Notes

Participants reference external sources like Wikipedia to explore concepts related to time travel and wormholes, indicating a reliance on popular science interpretations rather than rigorous scientific discourse.

Hi all, not sure if any of you all have watched it. Denzel washington acted in it.
http://www.imdb.com/title/tt0453467/"

I have a question regarding what they said, they need to keep the mass low if they want to transfer an object into the alternate universe, which in the movie it's called the 'Past'.
I don't understand how mass is related to time travel.

Basically, they sent an object into the alternate universe via a wormhole.

Hi Chaste! :smile:

Obviously, this is complete rubbish, but I think the idea behind it is that wormholes would be unstable, and too much energy (which includes mass) going into it would cause it to collapse. :wink:

(and technically what they did isn't time-travel, it's just travel to a different place in a very similar universe)

hey tim! thanks for your reply! ya, somehow they traveled to a different world with a completely same worldline just that it is 4 and 1/2 days ago.
But can you tell me what's the logic(explanation) behind too much energy(mass, E=mc^2) destroying the wormhole?

and do you remember the part where Denzel Washington points a laser pointer at the monitors and they said the EM field is destroyed?
Why is there an em field?
 
Is there a reason why this is such a curiosity for you? I mean, these movie-makers could simply make up some non-existent physics principles. They have been known to do that!

Zz.
 
Why are you looking for logic in a science-fiction movie's science? :smile:

oh. I forgot to mention I'm doing a presentation on a movie review. uhm, I'm just trying to pre-empt some questions from my audience
