Discussion Overview

The discussion revolves around the concept of whether the future can affect the past within the context of quantum mechanics. It touches on interpretations of quantum behavior, causality, and the implications of knowledge versus fact in understanding quantum phenomena.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions the validity of a claim regarding the future affecting the past, referencing a YouTube video.
  • Another participant describes a scenario involving a bullet passing through a slit and the implications of observation on its state, suggesting a relationship between observation and the timeline of events.
  • A different participant asserts that the future does not affect the past, citing the principle of causality, but acknowledges that future knowledge can inform our understanding of past events without contradicting causality.
  • Some participants express the need for a shared reference to facilitate discussion, indicating that without a common basis, further exploration of the topic is limited.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the initial claim. There are competing views regarding the relationship between the future and the past, with some asserting that causality remains intact while others explore the implications of quantum mechanics on this relationship.

Contextual Notes

Limitations include the lack of a shared reference for the initial claim, which hinders deeper exploration of the topic. The discussion also reflects varying interpretations of quantum mechanics and the distinction between knowledge and factual reality.

TL;DR
I saw about this in a youtube video that the future affects the past in the quantum world.
Is this true?
 
Physics news on Phys.org
Might be helpful if you gave us a link to the Youtube video you watched.
 
It was in my native language hindi. So you won't understand it.
 
He said that until we see something that thing is in wave form. But if we see something than that is in its normal form. So he gave the example by saying that if a gun fires a bullet through a slit. And you are on the other side of the slit and our eyes are closed and when the bullet reaches the other side of the slit you open your eyes. At that timeif you open your eyes. The wave of the bullet will go back to the moment when the gun fired. And this time the wave will be ready for you. When you open your eyes.

No. That the future does not affect the past is called causality.

However, the future may reveal more information about the past, thus as when we learn about new archeological findings. But this doesn't conflict with causality - only our knowledge is affected.

Some people confuse knowledge and fact in the quantum world, and then conclude wrongly that there the future affects the past.

We can't discuss a reference we can't see.

The short answer to your question is no. Any longer discussion would need a reference we can actually use as a basis for discussion.
