Reverse time dilation possible?

Click For Summary

Discussion Overview

The discussion revolves around the concept of reverse time dilation and its potential implications for computational power. Participants explore theoretical frameworks, speculative ideas, and possible applications in various fields, including biology and cryptography. The conversation touches on concepts from special relativity and exotic matter, as well as practical considerations for implementing these ideas.

Discussion Character

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

Main Points Raised

  • One participant suggests that if a computer were to travel through time slower than humans, it would appear to operate faster, proposing that traveling at the speed of light could be a means to achieve this.
  • Another participant proposes a method involving placing a computer on a spaceship far from Earth and manipulating gravitational fields to create a scenario where time runs slower on Earth, allowing the computer to complete tasks more quickly from its perspective.
  • A different viewpoint mentions that creating a large and dense negative mass could lead to gravitational time acceleration rather than time dilation, referencing previous discussions and literature on the topic.
  • Some participants express interest in the potential of light-based computers, suggesting they could operate faster than traditional electronic systems, though concerns about state change speed are raised.
  • There are references to previous threads discussing similar topics, indicating ongoing interest and exploration of these ideas within the community.

Areas of Agreement / Disagreement

Participants express a variety of speculative ideas regarding reverse time dilation, with no consensus on a specific method or theory. Multiple competing views and approaches are presented, indicating an unresolved discussion.

Contextual Notes

Participants acknowledge the speculative nature of their ideas, with some concepts depending on unverified assumptions about exotic matter and gravitational effects. The discussion also highlights the complexity of time dilation and its implications in different contexts.

I've become fascinated by the prospect of using reverse time dilation as a means to achieve a "holy grail" of computational power.

I'm probably going to get knocked down by not explaining this right (I haven't studied SR yet) but please try and understand what I mean. If a computer was traveling through time slower than us then it would appear to be working faster than if it was traveling through time in sync with us.

It has been suggested that we travel through time at the speed of light.

This could have extraordinarily implications for everything from folding proteins and other biological simulations to breaking ridiculously high strength cryptography.

Does anyone here have any theories on how reverse time dilation might work. No idea is to far out so don't hold back :)

So far I'm thinking about what might be "inside" a black hole or what could happen if exotic matter with negative mass accelerated to super speeds. Perhaps even the best way to do it would be to build CPU's that use Photonics instead of electricity through a semi-conductor.

Thanks and I hope this becomes a very exciting thread!

I don't know of a workable way other than mine:

Put your computer onto a spaceship and let it run your computer program far away from earth. Then bring the Earth near a strong gravity source (or the other way round). Every clock on Earth will run slower. When your computer program finishes execution, remove the gravity source and bring back the spaceship.

Don't try this method at home though!

We had a thread on this a while back. If you could create a large and dense negative mass (i.e. exotic matter) it would have gravitational time acceleration rather than time dilation.

The thread also had some references to the literature by Bondi and some semi-popular references. You can probably find it if you search the forum, if you look for my name, Bondi, and negative mass.

To create time acceleration would require bulk exotic matter, which may or may not exist. The Casimir effect shows that negative energy densities are possible, but this is not the same as bulk amounts of negative mass. There would be some rather unpleasant thermodynamic consequences to the existence of bulk negative mass as well, this has also been mentioned in past threads.

caston,

Nice idea, but actually, the computer has one of two options if one considers relative motion thru 3-space as the source for relative time ...

(1) It is stationary wrt you, at which point it experiences the passage of time the same as you do, such as sitting at PC typing these posts.

(2) It is moving wrt you, at which point it appears to you to run slower than a PC at rest with you.​

Seems that the only way to achieve your goal is to submerse yourself into an extreme gravity field, and let the computer run from outside the G field. Per you it'd run processing very fast, once you gave it a command. But then per those outside with the PC, you'd be the most slowest PC operator alive, and they could not reap the reward since the PC runs at normal speed for them :-)

Don't know about negative mass, but I'd tend to agree that a light based computer could open up the door quite a bit. May not need to be limited to base 2, and if it could be run primarily in vacu then it'd be fast as could be. However you'd need something to switch states, and so the speed of state change would be the limiting factor. But a base (say) 11 computer could be pretty powerful.
