When I was thinking on the TV idea, my brother came up with even more a challenging question: In a Universe where Retrocausality is possible but not always required(for an event to happen), would it still be possible to prove by logical reasoning the posteriority of an event? BTW, did you...

I don't want to brag but I know Greek, Hebrew, Japanese, Klingon, Chinese, German, Italian... and 42 other such words.

:smile: Yes, it's a contrived thought experiment!

Thanks for your replies. I am just using the Video Recording concept as an example instead of thinking in an abstract way about observation of an event with reference to time. So, don't worry about fake edits to the video and assume that the video is not edited after it's saved by the camera as...

I am looking for an answer based on Logic and not necessarily a technical one. Suppose, if I have a video clip of me doing something (let's call it event 2: E2) and would like to convincingly prove to others that it happened after a certain date - say, 2011-01-01. One rather simplistic idea...

I am hitting a wall. May I request another hint or two?

Thank you very much for the hint. I swear this not my homework. I know I missed something very basic but didn't know which one.

If two ℝeal valued, non-identity matrices A (dimension MxN) and B (dimension NxN) satisfy the condition A * B = A Is there a name for the relationship between B and A ? For example for: A = \left( \begin{array}{cc} \frac{1}{3} & \frac{2}{3} \end{array} \right), \quad B = \left(...

Thanks! I actually wanted to jokingly ask if the Gauge Boson and its anti-particle would annihilate and do things in the reverse and create a particle-antiparticle pair. What do I know...it turns out to be true :-p >> So, in reality this process reaches an equilibrium where it is...

Can two Bosons 'collide' in the same sense as the Fermions (Since Pauli's exclusion principle is not applicable for Bosons)? The Leptons have anti-leptons (positron, anti-muon, anti-tau and three anti-neutrinos). Each of the 6 Quarks have their corresponding anti-quark. So, do the gauge bosons...

I recommend "The God Particle" by Leon Lederman. It's a light-weight, humorous introduction to particle physics and the quest for the Higgs Boson. You will learn a lot about the past experimenters and their contribution to physics, the mysterious stuff that is matter, what particle accelerators...

Wow! interesting discussion. Thank you guys :smile: Guess, it all depends on what observer's definition of 'real' is. Energy may be an abstract form but the effects of expending energy are observable and real. Therefore, I would say energy is real and Photons being a form of energy transfer...

Ok, If I understand it correctly: a) We are limited in a way we cannot make truly continuous observation of the electron b) Observer would neither see electron appearing or disappearing. When observer 'sees' an electron it already exists at its position. Guess, it's like locating a rat...

When I was in School, my science teachers over-simplified everything to the point of being totally wrong. I guess, that's how they themselves were taught by their teachers.. or it could be that they have no idea they are wrong... or it could be that I didn't really understand them well (for a...
