PeroK reacted to PeterDonis's post in the thread A Inertial mass, the Higgs field, and Mach's Principle with
Like.
Yes. Only in the sense that "the vacuum structure" has the fact that spacetime is locally Minkowskian built into it, and that embodies... -
PeroK replied to the thread A Physical properties of the vacuum in GR vs. QFT.In GR the local tangent space at every point is the flat Minkowski geometry of SR. This is often, therefore, a good approximation for a...

PeroK replied to the thread A Inertial mass, the Higgs field, and Mach's Principle.Inertia is just another word for mass. That said Newton's laws don't apply to elementary particle physics.

PeroK reacted to Demystifier's post in the thread I Conventionality of the One-Way Speed of Light with Like.
The Einstein synchronization convention is just that - a convention. Physics does not depend on conventions. Various synchronization...

PeroK reacted to Ibix's post in the thread A Is there any topology behind factor 2 in Schwarzschild radius? with Like.
I think you can just absorb the two into the definition of ##G##. It's defined the way it is because we thought Newton's law of gravity...

PeroK reacted to berkeman's post in the thread Introduction: Independent Researcher in Foundational Physics with Like.
Welcome to PF. :smile: We do not allow personal theory development at PF. Please see the rules under INFO at the top of the page. We...

PeroK reacted to Ibix's post in the thread I Understanding the historical shift away from absolute simultaneity with Like.
For me, the simplest argument is to propose that if global inertial frames exist at all then the transformation between them must map...

PeroK reacted to A.T.'s post in the thread I Understanding the historical shift away from absolute simultaneity with Like.
The video below explains that pretty well.

Despite our species’ love affair with oversimplifying and trying to reduce things down to binary decisions, judgements, and perception...
-
I do not think that the angular momentum of the whole system about the vertical axis is conserved because of this:
-
Short answer: yes. You can perhaps take a peek at a recent study to get a feeling for the numbers involved...

PeroK replied to the thread Will Y-Direction Motion Cease with X-Direction Acceleration Only?.Look at it this way. If you consider a graph of you against the other eight billion on Earth, then it would be impossible to see you on...

PeroK reacted to haruspex's post in the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring with Like.
In reality, not only are all ropes somewhat elastic, so are all blocks and all ropes have mass. Starting with such a completely general...

PeroK replied to the thread B Does Time Pass at Different Rates on Other Planets?.Like a helicopter?
