Physicist Brian Greene blew my mind

This is science speculation gone wild.... sorry, the only multiverse I have seen was Stanley Kubrick's vision in "2001"...hey, didn't that already happen?

Thoughts or feelings are things and not the other way around.

All the wild hoopla about CO2 is misplaced, new technology is rapidly transforming the oil and gas sector, and the ICE sector, to radically push down emissions

toward zero, No need to turn the economy on its head, to shut down the transportation sector, the heating industry, the airlines,....

More political speculation based on industry propaganda about possibilities in the 'pipeline'.

There may be 'wild hoopla' about Harvey Weinstein's conviction, but maybe it's just 'tame hoopla', like that surrounding COVID-19.

There are couple of things. Gravity is very "weak" compared to other forces (as someone said, that is why all the electrons in your body don't fall to the ground). There is a speculation that the force is leaking into other universes.

Second is quantum computing. A quantum computer with only 81 bits can be computing in 2^81 parallel streams at once. There are only 2^80 atoms in our universe. The speculation is that the extra computation will occur in "hardware" in other universes.

Science fiction...we need a visitor from a multiverse to appear in our universe and fill us in on life beyond the beyond...wait a minute, wait a minute...where

have I heard that idea, of life beyond our visible universe? I think that it was somewhere in church, right? I guess everything old is new again.
 
So, from this thread I understood that:

AuBoy's mind is currently residing outside of his head.
His head is still crewed on his shoulders, so his mind must be making a connection with it.
Parallel between that and the talk about multiple universes?
Profit.

We need a witness, abstract math doesn't do it.

Unfortunately, evidence is mounting that the Universe(s) is nothing but mathematics. It is as if mathematical structures can come to life and become Universes(s). The clue lies in the fact that math can describe several phenomena to incredible precision, much more than can be expected by intelligent "approximations." This bothered Einstein a lot. Now it has been taken further and the speculation is that it is not about clever humans making great models about physical phenomena, but rather that the math IS the reality. Someone even said that the best way to describe an electron is that it is an equation.

Various multiverses correspond to different mathematical structures. Our Universe is described as a SU(3) group - Special Unitary Group of Degree 3.

Sorry, that sounds like an abstraction. I have never had an intelligent conversation with a mathematical equation. Mathematics is as silent as the grave.

Now, we can project features on to mathematical formulae, but to suggest that intelligence is inherent in mathematical processes is a dream.

Perhaps an an intelligent conversation is the result of a mathematical equation..., and dreams also.

The dream might itself be a mathematical process.

You need to stop thinking in anthropic terms. Mathematics may not be interested in conversing with you. Common sense has long since gone from Physics. What we call common sense is not sense at all - it is a narrow body of knowledge based on our limited capabilities. nothing more.

There needs to be an independent intelligent correspondent to relate to.....the math equation is not independent, but a product of someone's brain.

No, math is our servant, and a product of our own intelligence. A subservient machine. I need an independent intelligent correspondent to communicate with,

not some pre-programmed response.

Yep, Einstein couldn't understand Quantum Physics at all
didn't einstein propose the concept of a quantized electromagnetic field? i thought einstein was the one who highlighted entanglement as an implied feature of QM to the oblivious copenhagen orthodoxy at the time? he seemed like he had a lot of good contributions and critique to the development of QM. sounds like he understood it (to the extend anyone else did/does), but didn't like some of the implications, especially to do with entanglement.

an example of someone who couldn't understand QM at all would be like jim courier.

RU being facetious?

Einstein played a major role in developing quantum theory, beginning with his 1905 paper on the photoelectric effect. However, he became displeased with modern quantum mechanics as it had evolved after 1925... He was skeptical that the randomness of quantum mechanics was fundamental rather than the result of determinism, stating that “God does not play dice with the universe.”

Einstein was definitely one of the founders of QM; however, he was more of a realist.

why does being something of a realist need a "however"? QM interpretation seems to still be a wide open book. just about every flavor of philosophical foundation has been in, and continues to be in the mix. sean carroll has been spamming his fondness of the everrettian interpretation on his book tours, which seems to have given the interpretation a second wind in the quantum foundations community. and this is a fairly realist interpretation, although annoyingly exotic and "out-there"
