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.
he’s 80. he’s just old and losing it and trying to stay relevant.
he is legit and was dope in the 90s/2000s, he has just started losing his mind due to being old.
sort of like trump and tariffs. those were suppose to solve my athlete’s foot too.
His books decrease in quality the later you go.
One of his older ones (Hyperspace) is quite good and filled with lots of real science and math. Visions is pretty good too.
I think he leaned into the TV spots and airplay a lot and ultimately, fantastical stuff sells better. And now it doesn’t matter what he says, it just makes money.
See Neil DeGrasse Tyson for a similar story, though perhaps at a different point in his career.
Ah Neil "in the mirror you can only kiss yourself on the lips" Tyson
Omg I had forgotten about that.
Yeah so… Maybe NDT is even further along than Kaku.
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
if you give them equal advantages
I think this is key. Top Supercomputers can currently simulate up to 50 cubits. Quantum computing is already at 98 cubits
the moment i see this guy appear on screen i know ive fucked up
What he’s probably saying is not that far out.
Dark matter was proposed initially because at galaxy scales the gravity force doesn’t seem to match the one created by the visible matter in that galaxy, while others tried to propose modified laws of gravity at that scale. He is probably defending the later via compactified dimensions, so at some scales gravity stops transmitting at one over the distance squared, as those extra dimensions start to make an effect somehow.
In case someone thinks I’m saying something crazy imagine a universe that is an infinite straw. When you zoom a lot in the surface you see two flat dimensions, so gravity would propagate at one over the distance. When you zoom out you stop seeing the dimension that loops over itself and only see one, so gravity gets constant at that scale.
You could get the same with a lot more complex manifolds, that look like 3+1 dimensions at some scales.
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.
He has a PhD in theoretical physics, not a theoretical PhD in physics.
lol, I just rolled through HELIOS One on this current play through of F:NV

I remember from a podcast with a guy in the same area of Kaku saying that he’s not seem with good eyes in their community for saying things that doesn’t make much sense.
That’s a tad vague. Who said the quote?
“Never shall two scientists of the same trade meet, but the conversation ends in a fight over semantics and one-upmanship.”
It was probably me, but I’m paraphrasing here.
Not a Kook, he is Kaku.
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.)
don’t talk about my mom like that.
how can time be real if we don’t even know how magnets work?
and how can magnets the whole thing if our eyes aren’t real?
while we’re at it, if our eyes aren’t real how can we dream that you, um, you had, your, you- you could, you’ll do, you- you wants, you, you could do so, you- you’ll do, you could- you, you want, you want him to do you so much you could do anything?
they dont think it be like it is but it do 🤔
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 )
Yeah, this guy is so full of shit.
Edit: Whoever doesn’t like it, go watch his discussion with Roger Penrose, etc. He’s so obviously out of his depth when he’s not talking about speculative pop science bullshit.
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.
It’s not like Penrose doesn’t get out of his depth pretty rapidly. I read The Emporer’s New Mind and my first reaction was has the guy never heard of a heuristic? Brains aren’t perfect Turing machines but sloppy approximaters that make “eh, good enough” decisions.
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
27% of the matter in the universe isn’t a leak, it’s a deluge. With that much gravitational force, seems like the other dimension would be pulling part of our universe into theirs.
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.
imho gravitons are the key to interstellar travel. we need to find a way to aggregate and harness them
cool theory, Probably impossible to test let alone prove. but fun theory anyways.
Would it be OK if I pat myself in the back because I wondered if that was a possibility when I learned about dark matter? I’m not a physicist, but I was thinking about parallel dimensions fiction and asked that question.

Aren’t all dimensions parallel in the multiverse?
The “chicken attack” guy is a physicist?
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.
