>Maybe the physicists involved are unimaginative or unwilling
So they proceeded to waste their entire careers grovelling for funding for a worse solution? If you have a solution that dosen't take billions of dollars you will find seed money. Tokamaks have momentum now because people invested their time in them.
Bussards Polywell is a great example because it was funded despite being a gamble, it has not paid off. Look at general fusion, look at z-pinches, look at farnsworth type experiments. They got money, proof no one is scared of loosing their grant.

>LM acknowledging it makes it seem viable

The Polywell scientists made that claim. They still had trouble finding investors. The way you put it, you'd think there would be private investors all over the place trying to get a piece of the pie, but that's not what happened.

Neither the NIF or ITER are expected to produce power themselves. If someone demonstrates a fusion device that produces more power than it consumes, and doesn't destroy cities, they'd have billions easily.

It's the chicken and egg problem, to demonstrate a working prototype, you would need funding to put model into physical world.

Before a working prototype exist, it's been hard for the those approving funding to judge the energy-in and energy-out estimates in the models.

Could somebody plainly explain what the holographic universe theory is really about?

I don't wish to incur the wrath of the more knowledgable, but the way I have conceptualized any "holographic universe" theories is that their distinctness from string theory is mostly derived from new age spiritual implications made by the authors and that it attempts to explain things in a similar way. but from a perspective relying more on home-spun analogies than on the process academics tend to use.

Basically, I think describing the universe as a hologram of a lower dimension, or as a reflection of a higher dimension is functionally identical to the average person. Whether you describe it as super-string shadows or as holograms depends on who you read. This isn't to say they are perfectly equivalent. I believe string-theory has been subject to far more scrutiny and is thus more useful for informing research.

guys guys 2d simply refers to the fact that the information of 3d space is projected much more accurately on a 2d plane rather than the 3d space itself. Like the "film" to project a movie is a much more accurate description of the movie than the actual movie which has depth. the screen or the film dont.

The problem with this is that in 2d, the configuration or code of the 3d space is completely scrambled so we can't make it out what it would look like in a 3d space.

Russia got another rocket up with supplies already. It's not really the ISS supplies that matter, since they are an easy, relatively cheap payload that can be launched from many sites on the planet. The real loss here was the experimental cryptography technology that was on board. An experiment that may have cost as much as or more than the rocket itself was likely destroyed in the accident but because it's classified we don't get to know exactly what it was or how much it cost.

The space station has enough supplies to last until well into next year, and there are plenty of other launches scheduled in the meantime (from Russia and the US).

The Dragon capsule just returned last weekend from a 4 week resupply mission, and Spacex is scheduled to launch another one on December 9th. They're going to slightly modify the manifest to account for OSC's failed launch. This one's going to be even more interesting, because they might try to LAND the first stage on a floating platform after separation (albeit with less than 50% chance of success)

I thought it was like, understanding how when you move around someone's glasses and their lenses change color, it's actually a constant projected 3D shape and whether your pupils are in the color determines when it appears that color

So put that on the rest of the particles, since they all ended up being "ripples" and "resonances"

Classical understanding is, the number of possible states (for simplification, places in a box) scales with the volume or space the box takes up. But some really clever guys studying what happens to stuff as it falls into a blackhole found out a way to preserve the information seeable from the rest of the universe (because this is a very fundamental part of quantum theory, which the guy saying "nope its gone" was disregarding because he kinda likes to be reckless). So the guys who found out how to preserve the information measured it again... and to their surprize, found that it scaled not to the space the black hole took up but to the surface area at the event horizon, or instead of the places inside the box the places directly touching on the outside of the box. They went back to classical theory and crunched the numbers while making the adjustments they did and found out that it's actually a general principle, assuming their right about how quantum field theory works, that the number of possible states scales with area, not volume.

The idea's only needed to explain what happens when stuff goes down a black hole, but hypothetically it could apply to the whole universe, making one of the dimensions unnecessary mathematically even though its pretty much real.

what if your a boltzmann brain and the only one in existence and the only reason the dream tells you not to kill yourself is because it evolutionarily doesn't want to die

the parts that told you to die suceeded in killing off regions of your conscience without ending you wholly, like a seizure that lops off a little bit of the connective tissue and dissociates the right and left. they died in your life by fading away, they're only hope being memories of life before copying a lossy compressed aspect back into reality from the memory

in truth all your pain is utterly unnecessary. everyone's is, though yours is the only one that's real. your pleasure is illusary, it's just how into the dream you are, it's painlessness, plus the little subroutine of dopamine you've dreamt up. but you open your third eye and all you see is chaos - chaos not even lovecraft could fathom - formlessness, emptiness, no up, down, forward, backward, side, side, future, past. just cacophonous noise for eons made milky semen colored opaque by utter nothing

you were born of fluctuations between 4 dead fields, just a momentary accidental low entropy wrinkle in the manifolds of what actually is

so you fall back asleep and dream up a new life, while the chaos of nothing and everything eats at you, righting your entropy back to equity with all else for another quadrilion eons until the next boltzmann brain is born crying, hot, cold, alone in the garden of pure logic in which all universes manifest

and the poor miserable thing dreams the same dreams, as its aches and pains as its ideas disappear and manifest slowly torture it to death too

and so on and so on, just like nietzsche's eternal reoccurance

No not your brain, the ideas inside it. So like ideas you have usually even this world have certain standards that act as powerful selective forces - you can have contradictory ideas but you usually don't spread nonsense unless it's dangerous or funny - which just goes to show, not every idea propagates based on their truth-value.

Imagine some ideas like a badly written program embedded with its own kernel. At some point they're going to be so bad they'll draw so much power that they break the circuit and render the whole thing useless. The ideas that didn't do that are still functioning and copying and moving etc; the bad ones eliminated themselves from the evolving copying moving pool by shutting off a bit of their environment.

Yeah it's a funny etymology thing. We called the thing we walked on "Earth". So yeah, we dig up the "Earth". But then we discovered it too was just a planet, which we kept calling "Earth". If Martians coincidentally developed English the only difference would be they'd grow up calling dirt "Mars". "Earth" only came to mean "soil, dirt" because that's what Earth is made out of.
"Ay let's go dig up the mars!"
