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

Click For Summary
SUMMARY

The forum discussion centers on the science fiction movie "Deja Vu," starring Denzel Washington, and its portrayal of mass and wormholes in relation to alternate universes. Participants debate the concept that maintaining low mass is crucial for transferring objects through wormholes, as excessive mass could destabilize these theoretical constructs. The conversation highlights the distinction between time travel and traveling to a similar universe, emphasizing the fictional nature of the science presented in the film.

PREREQUISITES
  • Understanding of wormhole physics
  • Familiarity with the concept of mass-energy equivalence (E=mc²)
  • Basic knowledge of alternate universes in theoretical physics
  • Awareness of the differences between science fiction and real-world physics
NEXT STEPS
  • Research the stability of wormholes in theoretical physics
  • Explore the implications of mass-energy equivalence on theoretical travel
  • Investigate the concept of alternate universes and their characteristics
  • Examine the portrayal of scientific principles in science fiction media
USEFUL FOR

Film critics, science fiction enthusiasts, students preparing presentations on cinematic science, and anyone interested in the intersection of science and popular culture.

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
