Discussion Overview

The discussion centers around the possibility of time travel through communication with the past, as proposed by a scientist claiming future technology will allow individuals to "talk" to their past selves. Participants explore the feasibility of this concept, referencing theoretical physics and existing paradoxes.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant expresses skepticism about the validity of the scientist's claims, arguing that the proposed method of rewinding matter and extracting past interactions is physically impossible.
  • Another participant acknowledges that while many physicists point to paradoxes that suggest time travel to the past is impossible, there are solutions in General Relativity that indicate it might be possible, such as closed timelike curves.
  • A different participant humorously compares the concept to something from science fiction, indicating skepticism about its plausibility.
  • Concerns are raised about the implications of observing the energetic states of atoms, with a reference to the Principle of Uncertainty suggesting that such observations cannot be made.

Areas of Agreement / Disagreement

Participants generally disagree on the feasibility of the proposed time travel concept, with some dismissing it as impossible while others point to theoretical frameworks that suggest it may not be entirely ruled out.

Contextual Notes

Limitations include the reliance on speculative claims made by the scientist and the lack of consensus on the interpretation of theoretical physics related to time travel.

This is an article about some scientist who claimes he is/will be able to see and hear into the past. He claims in 20 years we'll have the technology to "talk" to ourselves in the past, say at our desk 30 min earlier and pass on instruction "verbally" through whatever means he claims to possess.

I know this article is obviously bs as the method he describes to accomplish his theory requires him to virtually rewind matter and extract past physical iteractions from an object. meaning look at the current energetic states of all the atoms in an object and derrive how the atoms current state originated. Sorry to post this but there are people on a non-physics forum i frequent that believe what is being said is possible. I apologize for posting this but my current grasp with physics is not enough to elegantly explain why his proposal is completely impossible. Could someone give a thurough explanation expalining why physically it is not possible?
If it is a complete waste of your time for me to posting this then i apaolgize.
thanks
 
Physics news on Phys.org
Okay, so a guy without a name who is unfunded and works alone in his basement says so. Well, I'm convinced. :rolleyes:

However, there is no absolute answer as to what is possible here. From what I read of the big names in physics, most people point to various paradoxes that would seem to render travel to the past impossible. However, there are solutions to the equations of General Relativity that suggest time travel to the past might be possible, and people have been playing with this for quite some time now - closed timelike curves. And there are a number of designs for time machines that some qualified people have argued might actually work, so, to the best of my knowledge the door is closing for now but not completely shut on this idea.

Still, the page linked is bogus.

That sounds like somthing form star trek.

There is no way to look at the curreny energetic states of the atoms, since it goes against the Principle of Uncertainty. It is all BS.
 
thanks for the replies:smile:
