renormalize's latest activity
-
Rrenormalize replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Yes, as I tried to point out to you back in post #8, namely the theory of causal sets. Rafael Sorkin has authored a readable review of...
-
Rrenormalize replied to the thread High School Is there anything in the Universe that is not fundamentally made up of matter?.You're still way too vague. Does your list of "things" include, e.g.: energy, entropy, the color red, music, love, thoughts and prayers...

Rrenormalize replied to the thread High School Is there anything in the Universe that is not fundamentally made up of matter?.You need to define "anything". Things that physicists characterize as matter/material/substance are all made up of one or more of these...
-
Rrenormalize replied to the thread High School Is there anything in the Universe that is not fundamentally made up of matter?.The 18 quantum fields already encompass anti-particles where appropriate. For example, the 4 complex components of the Dirac electron...

Rrenormalize replied to the thread High School Is there anything in the Universe that is not fundamentally made up of matter?.Modern physics quite simply views "matter" to be any of the 17 quantum fields that appear in the Standard Model (SM)...
-
Rrenormalize replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.The natural activity you describe is indeed direct empirical evidence for the existence of a Lorentzian metric on spacetime, from which...

I answered the question with "Yes a causal or timelike structure can occur without assuming a metric because of the network of relations... -
Rrenormalize replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.OK, this is a response to the OP's original question about the possible structure underlying classical spacetime. But you then write...

@OmniThoughts Please don't post chatbot output here. If any of us wanted to have a conversation with a chatbot then we would just ask... -
RHi David, Sadly Zenodo is not a peer-reviewed reputable journal. I encourage you to read our global guidelines (url is in my signature...
-
Rrenormalize replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Can you illustrate your distinction between a law and a relation using examples from physics?
-
Rrenormalize replied to the thread Undergrad Photons & Time: t=0 What?.Yes, the time on the ship is still "normal" because relativity states that a massive ship must always move at less than the speed of light.
-
Rrenormalize replied to the thread Graduate Can a causal or time-like structure emerge without assuming a metric?.Take a look at https://en.wikipedia.org/wiki/Causal_sets: "The causal sets program is an approach to quantum gravity. Its founding...

Haha.
I guess that means you are well sprung.
