Creating mass from nothing with time travel

Click For Summary
SUMMARY

The discussion centers on a theoretical concept of creating mass through time travel, specifically using a cube with a mass of 1kg. The idea proposes that by traveling forward in time and returning with the cube multiple times, one could theoretically generate infinite mass. Despite acknowledging the impracticality of time travel, the discussion draws parallels to established paradoxes like the grandfather paradox, highlighting the complexities and absurdities of time travel theories.

PREREQUISITES
  • Understanding of basic physics concepts, particularly mass and time.
  • Familiarity with theoretical discussions surrounding time travel.
  • Knowledge of the grandfather paradox and its implications in physics.
  • Awareness of science fiction narrative structures and their relation to scientific theories.
NEXT STEPS
  • Research the implications of the grandfather paradox in theoretical physics.
  • Explore the concept of mass-energy equivalence in Einstein's theory of relativity.
  • Investigate current scientific theories on time travel, including wormholes and closed time-like curves.
  • Examine the role of time travel in science fiction literature and its impact on public perception of physics.
USEFUL FOR

Science fiction writers, physics enthusiasts, and anyone interested in the theoretical implications of time travel and mass creation.

So I had one idea. Let's say that you have a cube, it's mass is 1kg and you travel forward in time 10 years and bring it back. Now you have two cubes. Then you go forward again, this time 10 years - 1 Planck time into future. Then bring that cube back again. You can repeat this infinite number of times. You just have to go 1 Planck time before last time. You can create infinite mass.

I know this is just stupid because time travel does not exist and discussing this doesn't make sense, but I wanted to share this.
PS - maybe it's not that stupid, people discuss the grandfather's paradox and that is also not at this time possible.
