Quick! Get the Flexseal.
holy shit, underrated comment. got me good m8
This guy is mostly famous from poor quality history channel scifi bullshit "documentaries".
He's literally just the Ancient Aliens guy but with a PhD
I thought this guy was a legit scientist, but I read his recent book Quantum Supremacy and it was all shit like "with quantum computing, in the future you will be able to solve athlete's foot". Literally everything you can think of is going to be quantummaxxed by cubits, according to him. Need your car serviced but the garage isn't open on Sundays? Quantum computing. Need your mother-in-law to dial down the snarky comments about your new house? QUANTUM COMPUTING. Frequently walk into a room, forget why you went in there, leave, then immediately remember why you went in the second you cross the threshold? MOTHERFUCKING QUANTUM COMPUTING!
I'm sure he is a legit scientist, of course, but as a science communicator and terminal book-hawker, he's no better than Joe Rogan.
A young woman from Washington state university has already proven classical computers can solve just as well as quantum if you give them equal advantages. Everything saying quantum computing is faster is operating on the unspoken principle of having the entire data grid already preloaded and comparing it to classical computers who do not have the entire data grid preloaded but when you give them both the magic preload pill quantum computers aren’t any better than classical
the moment i see this guy appear on screen i know ive fucked up
To be fair, this is the level of physics where if they discover things right out of fantasy book (teleportation, mind reading, transmutation etc) I wouldn't be even surprised.
How many of these physicists do you reckon have shared a cup of tea with Cthulu?
There are a few that have had tea with Cthulu. Not many, but a few. Physics at this level is sometimes about taking a good hit from a pipe and going, "What if" and "What might happen if"
Then they let real mathematicians and engineers figure it out to see if they hit on a lucky guess, Oh and Grad students. Can't forget the all important Grad students.
parallel dimension
Aren't dimensions by definition orthogonal?
That is true for space dimensions, but there is also a time dimension, and would another dimension, that is 'orthogonal' to a time dimension not be some kind of dimension that offers alternative time lines?
Got'em
There is not a single thing we know about dimensions. I don't believe it
What about infinite dimensions?
I know a thing or two about the first three, thank you.
Yeah?! What's their middle name then?
3rd “Lionel” Dimension
quick, get the xkcd
Yeah, this guy is so full of shit.
Angela Collier's video about this: https://youtu.be/wBBnfu8N_J0?t=2213 (Kaku part starts at 36:50).
A TLDW on the rest of the video: "Gell-Mann Amnesia" is a term Michael Crichton coined. It refers to how people read articles in a newspaper about a topic they are experts in, realize it's all horribly written trash, then turn the page and happily read the next article about an unfamiliar topic forgetting they just learned the newspaper is trash.
Collier expands on the idea to include the Gell-Mann Complement and Gell-Mann Recollection. The Recollection is what Kaku does, where he doesn't know anything about a topic but presents a simple explanation on it anyway just because he's an expert in something different. This frequently gets him into completely bonkers territory, like Deepak Chopra level bonkers.
Kaku is very good in physics, he just decided to make money instead of doing proper physics.
Penrose is also considered somewhat wacky in the field, mostly because of conformal cyclic cosmology, but does proper physics

What's a parallel dimension?
He maybe means a parallel universe. Or a higher order dimension like in string theory. This guy is a string theorist so probably the latter.
String theory was all the craze, at a time.
String theory makes more sense if you take some LSD I think.
If you can place a dimension that is orthogonal between two dimensions, then those two dimensions are parallel. /j
I see nothing wrong with suggesting that, so long as it is made clear he is discussing one of many theoretical possibilities.
Is he a kook? He does kinda look like one, but so do a lot of legit scientists, so that's not a good measure.
Not a kook. Legit scientist. He has a PhD in theoretical physics, not a theoretical PhD in physics. While he spends a lot of time as a science communicator, he has his bona fides.
Yes, it's all just theories and intuition like all nascent science.
A PhD is not a "get out of Jail" card for kookery.
He is definitely part of the "woo" people in his field.
I read a book of his once about theoretical ways to make sci-fi technology a reality. It was interesting in a hard sci-fi kind of way, but what really annoyed me was that he kept presenting his ideas as how they would work rather than how they could work.
Just looking at what people 100 years ago thought life would be like today should be a good indication that while theorizing about the future is interesting and a good way to get ideas moving, future technology is never going to be exactly what you think it will. If we knew exactly how this stuff would work, we wouldn't be imagining it, we'd just make it.

I've been insisting this for years:
it eradicates the bullshit of hyperinflation being required to smooth the CMB,
it explains why gravity's sooo weak, compared with the contained-within-this-3d-space forces, like electromagnitism,
it explains why there exist galaxies of dark-matter which don't have any conventional-matter,
it explains why there exist galaxies of conventional-matter which don't have any dark-matter.
The gravity's diffusing through MANY 3D-spaces, not just ours.
the other forces are contained-within-this-3D-space.
Therefore OUR gravity is "dark matter" in other 3D-spaces, too.
The smoothing-of-the-CMB is simple: instead of 1x 3D-space having hyperinflation, there are thousands of 3D-spaces ( or zillions: whatever the math says matches ), & EACH of them inflated at speed-of-light or less, not at zillions-of-times-c.
The painting-method called "glazing" is essentially the same idea:
da Vince used many many thin layers of paint, to make ultra-smooth tones..
the many-many-many-3D-spaces all "underlying" each-other smoothes-out the gravity among them all, so local-lumpiness simply isn't a significant part of the equation, as it would appear.
Part of this is on the E = speed-of-gravity * mass * speed-of-light, though, so it's arithmetically identical to the conventional E=mc^2 rendition,
but would gravity & light both be traveling at the same mps speed through say a 100km of quartz?
XOR would the refractive-index be different for gravity & light?
That structural difference is what the speed-of-gravity * mass * speed-of-light variant was trying to show.

Scientific method and all that. Any conjecture is okay.
Now, what's the hypothesis that you can make out of it? We've plenty of observations that don't match theory, which we believe to be on account of dark matter - galaxy rotation speeds, what happens in the core of a type 2 supernova, and so on. Does this hypothesis explain those problems better than what we have?
If it does, keep it. If it doesn't, discard it. Repeat, until we've solved all the mysteries of the universe by banging our heads against them.
This strikes me as the kind of conjecture that has no predictive power, and therefore must be discarded, but I'm no PhD-level theoretical physicist.

Maybe it doesn't provide much in itself, but can help with providing an alternate framework for thinking about observational anomalies in the future.
Heliocentrism didn't actually improve the predictions of planet movement over geocentric models with epicycles, at least until Kepler swapped out circles for ellipses. So heliocentrism didn't give an immediate advantage, but laid the groundwork for later improvements that could surpass the limits of geocentrism.
As long as we do not know what Dark Matter or Dark Energy is, any hypothesis is valid. Scientific method is to err above towards the truth.
A hypothesis is only valid if it has any basis in reality AND a way to falsify it.
You can't just say "it's cause god got bored" that's not valid.
You can say "it's another dimension leaking, here's something we can check and if we observe this, then it's not true."
Just throwing out random ideas isn't a hypothesis, it's fiction.
What if dark matter is a time artifact of gravitational waves over time/space as particles with mass travel through time/space? (I am not a physicist and I don't understand jack shit.)
Oh shit, reverse the flow to the warp coils! Dump all energy from life support into forward shields and laser missiles, our only chance to defeat the psychic alien is to reverse and restart time for .00001 second, creating a terminal in the psychic time loop. Once free, we can concentrate our dark matter on the psychic alien, stunning him for just long enough to get him to buy a sketchy timeshare on Mars.
Thank you science word rearranger celebrity with NGL pretty good hair
What if time and space are but a dream that was merely a concept and we're just the avatars?
(Also not a physicist but mildly interested enough to be uncomfortable yet intrigued )
