This picture doesn’t really make much sense, because Stephen Hawking couldn’t move, so how is he shrugging in this pic? And why would he bother making theories about fictional talking horses?

Pinkie Is so cute in this pic

@Ninji  
The most disturbing theory is that no one exists around anyone, because we can’t prove anyone else is a person since we only see each other from our perspective and no one else’s.
 
It’s like Jim Carrey’s idea of being “woke”

@wrabbit  
But is Background Human’s Boltzmann Brain sufficient enough to make a good Gen 5?

Where Hawking is now, even Pinkie makes sense. RIP.

@Background Human  
Good enough to create the fourth gen of MLP.

Stephen is the best physicist that ever existed!

@Ninji  
Cogito ergo sum. Even if we can’t be sure that our observations have any objective validity, we can be sure of the observations we make. Whatever Matrix we’re in appears to be consistent and governed by mathematical formulae, and that’s good enough for our purposes. Good enough to create the appearance of cat videos on YouTube, anyway.

@Ninji  
I enjoy being a sapient figment of your imagination then, good sir!

@Dust Rock  
Not only that, but everything that science has built up is ultimately based on multiple assumptions.
 
That there is an objective reality shared by all rational observers. (we can never know this)  
That this objective reality is governed by natural laws (we don’t actually know this either)  
That reality can be discovered by means of systematic observation and experimentation.
 
From my point of view science produces usable predictions, but I could be in a rubber room being injected with space drugs by magic ponies for all I know.

@Darth Sonic  
If we’re truly thinking beyond the minds imagination then nothing can be disproven or proven due to the theory of infinite possibilities.
 
We could be a thought, simulation, mind control, hypnosis, etc, etc.

@Cirrus Light  
The problem with ANY multiverse/omniverse theory is that while it can be proven (just open a portal to Equestria; McDonalds will LOVE the new influx of customers!), it CANNOT be disproven due to the possibility that we are somehow isolated from the rest of the omniverse in order to fulfill that “every possible world that can exist” checklist, including a universe without a multiverse.

@Ninji  
Berkeley screams in the distance

@Cirrus Light  
The multiple layers of existence alone is enough. When you tamper with the other dimensions of existence you can get stuck by changing a law on accident.
 
An example of this is hacking your computer and accidentally disabling a necessary program. You just can’t tamper with reality or you’ll be lost to it.

@Cirrus Light  
Or did you need a citation on the resistance to acceleration caused by confined light speed moving objects? I wasn’t sure, because it’s pretty much right there inside the photon box experiment.
 
A photon is a quantized unit of electromagnetic energy, and since there is no smaller components bumping around inside of it, it will always move at causal speed. A proton however has a bunch of crap bumping around inside of it, causing its position to stabilize and resist acceleration.

@Cirrus Light  
I didn’t know it changed based on your units. Often when fiddling with the geometry it’s easier to assume c=1.
 
Also  
https://en.wikipedia.org/wiki/Weak_hypercharge  
I wish I could find something in English, but in the second paragraph it describes many leptons interacting with the vacuums non-zero value, and gaining a chirality flip from a tiny extra charge called ‘weak hyper charge’ or ‘hyper charge’ in the strong force. This keeps the lepton from moving in a straight light speed path, because now it’s tumbling around and gaining new interactions (IIRC only electrons with the same chirality will interact with eachother, but I know it’s something of this nature)

@Ninji  
Actually, its angle depends on your units. If you work in standard metric units, then the light-cone is actually at an extremely wide angle.
 
It does make a 45* angle when you appropriately use ct or normalized units for the scales, though :q
 

You got a citation for that, though? I don’t know much QM, but that doesn’t sound familiar much to anything I know, and the photon box just illustrates how photons have momentum and energy despite having no rest mass, and the equivalence of mass and energy.
 

 
@Cyan Lightning  
Yeah, of course, understandable.

@Cirrus Light  
Don’t get my wrong, I am still interesting with science, but unlike few years ago. I only mainly focus on few things, I mean it would be useful for me to learn music theory and how note resonate with each other to create a harmony chords than learning a theory about how universe come to be. Either you misunderstand what I said or I just didn’t explain it quite enough. What I really trying to said is that you have only one life, you have a limited time, you can’t focus on everything only small thing. Yes, science give use a lot of wonder technology that he have today, but a lot of the inventor that invent thing is just focusing on their own interest, I mean do Tesla need to learn about science of agriculture and evolution of cosmetic animals to invent AC current? of course not.
 
It’s fine you interesting to theoretical science, because that’s your passion. But that’s no longer my passion at least not into dive deep into it. We have to choose in this life or we aren’t going to anywhere.

@Cirrus Light  
Speed of causality. The speed in which all unbound matter propagates space time.
 
If you take one axis for space, and one for time, light always travels a 45 degree path. If I could travel faster than light I could cross over into your past or future, in a space-like path.
 
Electrons move slower because they keep getting bumped by low energy fuzz, and mass is generated from the resistance to acceleration that confined light speed objects create, giving us our mass-energy equivalence. This is best understood through the photon box thought experiment.

@Dust Rock  
Hmmm…
 
How does this deal with the Information Paradox? What experiment would test it? It is adequately falsifiable, right? Is it built on a pseudo-reimann manifold like classic GR or does it attempt to solve the renormalization problem? Also if you’re suggesting the antimatter went somewhere then I guess you’re prepared to use this to quantitatively solve the baryonic asymmetry problem and show why electroweak unification models don’t solve it as well? Does it give analytic solutions or does it have to be numerically computed? Is it embedded in an asymptotically flat, de-sitter or anti-desitter spacetime, or is it invariant to that?
 
:p
 
I think you are right, though: Spacetime is far more vast than the human brain can comprehend. But you don’t even need to leave our solar system to get somewhere far beyond the human mind’s ability to imagine.

@Cirrus Light  
As Twilight likes to put it- wait, I just realized twilight NEVER actually says we should learn anything, instead she usually is the one who learns stuff o.o up until the later seasons anyways.

@Cyan Lightning  
Eh, science is something that people pursue because they’re curious and they enjoy it. It can be surprisingly useful at times in everyday life, even, but no, it won’t help you get Groceries a lot faster or anything (though if you know heuristics for the travelling salesman problem it could save you a few minutes, but most people know those intuitively at least a little :P ).
 
As a whole, it’s really giving the world something that builds up over time to the point where it helps the whole world tremendously. It won’t help you do your laundry, but when you work together with thousands of others, and this happens for centuries, you get laundry machines and detergent and electricity and running water and self-propelled wagons and… yeah :q
 
But in case you doubt the practicality of these things - here’s a fun thing to realize: nuclear power and the atom bomb came from the questions  
a) why does light look like it’s going the same speed to everyone? and  
b) why does metal give off an electric current when you shine lights on it in this particular way and not in another way?
 
And sort of along the way were other questions like “how much light bounces back of different spectra when I shine a light on a thin film of gold”, and “how big are electrons?”
 
So it’s important science is pursued for its own interest, since you never know when, where, or how big the applications might be that seemingly suddenly spring from nowhere.
 

 
I mean, GPS satellites are only possible - and FTL may even be made possible by - trying to replace Newton’s theory of gravity since it’s incompatible with special relativity.
 
And radio only exists because of some useless thing about invisible light. What the heck kind of purpose can invisible light serve? Well, that’s radio and internet, so…
 

 
But if you’re curious, that’s reason enough to look into stuff, I’d say. Life isn’t just survival, but enjoying it, after all, and it’s fun to learn things.  

@Cirrus Light  
Space and time to me is much bigger than we can comprehend if my theory is correct, so I’ll go at it backwards to make it easier
 
Omniverse - Everything  
Megaverse - Contains every possibility of one world  
Multiverse - Contains every universe and it’s alternate timelines  
Universe - Contains pocket dimensions and galaxies  
Galaxy - Contains a large space of planets and stars  
Space - Contains​ every other layer of existence including the physical, spiritual, microscopic, digital, etc..
 
The only way it can be bigger and how much bigger is if there is indeed a “antiverse” where the negative anti matter got sent to after the big bang where everything is exactly the same, but sometimes crosses over whenever you feel that “ghost” feeling for only a plank second.

@Cirrus Light  
Well when I said time as 3 dimension is for simplification at least the way I see, I don’t have a major scientific background and probably won’t have a lot of interest to dive deep there. If you want to know how I come up with idea of the third dimension. Here’s how I see it, the first dimension is just time only moving from the past to the future while the second one is can move between between past and the future not just fixing moving toward future, while the third one is combination of the possibility of everything that can happened in other word multiple timeline.
 
To be honest, right now my interest to deep dive into scientific thingy is just dwindle. I haven’t read or rather listen to audiobook about science as I used to be and sure I love to read it but at the same time, I ask to myself “is it the knowledge that I gather from this books that I listen to is worth it for my everyday life?” aside from able to debate online or talk with my friend, there isn’t anything that worth it to me especially the debate online which usually end pretty badly. Right now the only thing that I really interest in scientific field is just self-help psychology and unlike other thing, it’s help me a lot in my life like overcoming a wound from abusive parents and other bad past, able to be more social, being more honest especially with myself, focus on my passion like drawing and composing music and any others.
 
The bottom line is that it’s fun to know learn a lot of thing, but we still have a life that we need to take care of.
 
Also, I read or rather listen to The Hidden Reality by Brian Greene and this is pretty much my reaction.
