Undergrad Emergent space-time from what?
Interesting argument, it will take some thinking upon. But unless we exist in a simulation, or God is real; ‘infinity’, you keep using that word... I do not think that word means what you think it means.- WhatIsGravity

Undergrad Is Big G and Dark Energy Constant Over Time?
Yeah, sorry about that, I'm not exactly sure what I'm asking either?! I guess I was wondering how gravity might be defined, simplistically speaking, without the 1/r^2 term. Basically tidal gravity. I think I can maybe understand how the EM fields work out in QED, but I can't yet wrap my brain...- WhatIsGravity

Undergrad Is Big G and Dark Energy Constant Over Time?
To bring up an older thread which I don't have too much time (or experience, education or knowledge) to think about... I guess now I'm wondering how a gravitational field, unlike the Higgs, might be defined without a gradient (spacetime) dependent field?- WhatIsGravity

Undergrad Is Big G and Dark Energy Constant Over Time?
I'm feeling quite uneducated and humble in this forum; much thanks hutchphd for the reference, but that seems kinda... numerological? Can't yet wrap my brain around how 1/m^2 in regards to a gravity (position) gradient is also (equally?) expressed as 1/s^2, but will read and think about it...- WhatIsGravity

Undergrad Is Big G and Dark Energy Constant Over Time?
Holy smokes, humbly and thanks for the responses. With our understanding of G, I can't imagine mass being defined by gravity. I was working with a company probably a decade ago who proposed a gravity (not mass) standard to BIPM (free fall gravimeter with laser length and atomic clock, both...- WhatIsGravity

Undergrad Is Big G and Dark Energy Constant Over Time?
I'm wondering if any of the physics Jedi out there might know of any credible papers that suggest big G and/or the cosmological (dark energy) aren't constant through time?- WhatIsGravity

Collection of Favorite Movie Phrases
Anybody want a peanut? You keep using that word. I do not think it means what you think it means. Quit rhyming, I mean it. I could have killed you. I believe you. True Love. You killed my father, prepare to die.- WhatIsGravity

Graduate Can Photons Transmit Negative Momentum?
Just to be mischievous... a photon passing through an event horizon will have a negative momentum... opposite it's velocity? But I guess at that point, what is velocity?- WhatIsGravity
