Erik Verlinde on the Cosmological Evolution in a Theory of Emergent Gravity. IU 2020

Erik Verlinde at the Information Universe, introduced by Margot Brouwer.
Erik Verlinde is a Dutch theoretical physicist, internationally recognized for his contributions to the field of string theory and quantum field theory. His PhD work in conformal field theories led to the Verlinde formula, which is widely used by string theorists. He is currently best known for his work on emergent gravity, which proposes that both space-time and the gravitational force are not fundamental, but emergent properties arising from the entanglement of quantum-information. Incorporating the expansion of the Universe into this theory even allowed him to predict, under specific circumstances, the excess gravity currently attributed to dark matter.

He is my favourite physicist...

Interesting to know how the holographic principle looks in the superdeterministic setting.

Margo gave a lecture at our Astronomy club last year, great speaker!

[SideWalkAstronomyNetherlands]

Erik Verlinde is debunking things. Great stuff..

This reminds of the epicycles when with more precise measurements of orbits they started introducing more complicated epicycles just to fit within the perfect circle as the ideal heavenly form but it was about time to discard a very over-complicated system to a more simpler one

Go back a few years and Eric's work was only seeking to give an explanation of Dark Matter, but accepted Dark Energy. He seems now to have considering DE as being more central in his thinking.

At the interface of event horizon, pulling matter and pushing antimatter reminded me Greenglow documentary and the theory of Dr Dragan Hajdukovic that antimatter creates antigravity, anyone agree that?

It would be nice to know why photons are so different in terms of entropy gravity: they can react to changes in a space caused by gravity (entropy osmosis), but at the same time they do not cause such changes. Behave like a gravitational diode -)

Well..the subject of gravity...much to do about nothing. I have discussed this many times, even with Nobel Laureates. It is neither illusive nor difficult. Let's rethink the subject from its origin: Einstein always described Spacetime as a form of ether without physical properties, other than offering us ‘yardsticks/rulers’ and ‘clocks’. Next, due to C being a constant, he (based on Lorentz and Pointcarre) correctly derived in SR the effect that high speeds have on the diminishing length of the speeding objects which he calls ‘length contraction’, a verified effect. Einstein even uses the term of ‘contracted rulers’ in this respect. But then he fails to link this term of ‘contracted rulers’ back to spacetime itself. Think of that for a while! It directly contradicts his key notion that rulers are a property of spacetime! As if objects become detached from spacetime and shrink by themselves. No, the only logical conclusion he should have drawn from his SR theory is that it is not ‘presence’ but of mass but SPEED of mass that leads to a (linear!) contraction of spacetime. With this, it is easy to explain the effects we attributed to ‘dark matter’. It's not invisible DM that causes high speeds of objects, but exactly the other way around: high speeds cause extra linear ST contraction or 'gravity' ! What Einstein should next have realized (using his own 'equivalence' principle) is that it must then also be the speed and vibrations of all tiny subatomic particles (electrons / nucleons) inside restmass, that generate contraction of spacetime around restmass (seemingly radially and weak since all these tiny ST contraction vectors are unaligned). This can easily be verified: Once you align the subatomic speeds of free electrons in metallic restmass, e.g. by applying an elecromagnetic field, you feel just how strong their collective focused speed induced ST contraction effect actually is: We then call this focused spacetime contraction ‘magnetism’ but fundamentally it is the very same effect of speed contracting spacetime. The community is literally inverting and distorting physics, teaching us fundamentally erroneous and needlessly complex (yet mathematically correct) rubbish. They simply do not dear to admit their shameful physical interpretation errors that led to ‘the big nap’ that lasted for 100 years now….It is useless to try to convince them. They like it the way it is. Lost in math for ever; a great way for tens of thousands of physicists to collect their pensions for ever...what would you do?
