ppl have looked at the equations to try and drop the negative energy requirement and they recently managed it. You still need the equivalent energy output of a star but in relative terms that's more manageable than creating negative energy
https://newatlas.com/physics/ftl-warp-drive-no-negative-energy/
So maybe it'll be called a Lentz Drive
I still think there's some mileage in the sailing analogy. The topology of warp bubbles and the "normal" universe are considered as separate things. I suspect there'll be some interesting physics going on at the interface between the two so even creating a microscopic warp bubble in a lab would be useful. Might even be doable with just fusion reactor power.
<addendum> IIRC another solution to the negative energy problem unfortunately was solved but only for sublight speeds. However it did incidentally alter the time flow within the bubble: the stasis field in Red Dwarf, accelerated crop growth... ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

I love theoretical physics but sometimes I come across topics where I am struggling to get on track with the logic. I am currently reading about the Einstein Podolsky Rosen paradox:
https://www.drchinese.com/David/EPR.pdf
I wish I had went into this field as an undergraduate instead of Engineering as it's infinitely more interesting but I would have probably hit my intellectual glass ceiling in there somewhere. ____________________ PRESENT: 2018 BMW S1000XR SE Sport.

I was reading an article on dethroning Einstein's General Theory of Relativity. As an aside it seems the assumption lately is that Quantum Theory is "correct" and Einstein is wrong (much the same as the patent clerk stole Newton's apple previously) but I rarely hear the other argument
Anyhoo, String Theory was shot down instantly due to the need for extra dimensions for the maths to work. Now I've always thought that higher dimensions make a lot of sense: it's not that a particle is in two places at once until you resolve it by measuring but that it lives elsewise and "protrudes" into the limited dimensions we experience in multiple places. Probably not fact or proven anywhere but if light "lives" as a wave in higher dimensions it will touch our dimensions at points we measure. The wave is going through both slits of classic experiment at once but we can only see the peaks. Obviously not as simple as that but hey, multidimensional physics either requires at least a doctorate or LSD to comprehend
Moving on from there Loop Quantum Gravity suggests that the fabric of space-time literally is a fabric and there's tiny (as in Planck's Constant tiny) loops - something poetic about it. Certain long distance Gamma Ray bursts are anomalous and LQG seems to have the answer.
And finally the most overt "fuck you, old man" was Einstein's thought that deep, empty space was uniform. Nope, empty space literally is empty. Of course if you went out to check you'd bring your own space-time with you from the mass/energy/space/time distortion of the space ship itself It has a certain "if a tree falls in a forest..." quality about it but it does have some interesting ideas on how quantum entanglement works. Something about "locality" which I need to read up on. ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

The reconciliation of General Relativity and Quantum Mechanics seems important, yes?
Let's start with E = mc2
Is this statement true?
What the letters represent and their underlying values is neither here nor there as actually the question should really be "can we use mathematics to prove things?"
And the answer to that is "yes and no." Yes you can prove things but only if you accept unprovable axioms. And there's the clever thing with mathematics: you can use it to prove that you can't prove everything with mathematics
A description of Quantum Mechanics that fits with General Relativity or visa versa a modified form of GR that is consistent with QM might not be possible not because it's an unsolvable problem but because it might not be solvable mathematically ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Old Thread Alert!
The last post was made 2 years, 333 days ago. Instead of replying here, would creating a new thread be more useful? |
