The stoned scientist
So I am starting to get into upper level physics classes and I was wondering, if you can imagine space like a sheet or like a set of sheets stacked on top of each other and able to be curved in any direction, just like that of 3D relativity. Doesn't the sheet have a natural resistance to the curvature it gets from mass? Space's natural state is in the opposite direction to mass so maybe it is constantly exerting some "anti-mass" or "anti-gravity", in dense regions of free space this energy might increase and lead to expansion??? I don't know just a thought2 AnswersPhysics3 weeks ago
I've always wondered how the early universe would have looked if no one was around to see it. I thought that because of how quantum mechanics depends on the observer and whatnot. But while driving and thinking I just realized that the early universe does in fact have observers. Us. We can look back and see the early universe and therefore give it a definite form. That's crazy to me and then made me really appreciate how time is relative. I then thought about how there might not only be alien civilizations looking at us through space but even from further ahead of us in time. I don't know it just sounds like an interesting discussion to me.5 AnswersAstronomy & Space3 months ago
I know that question might not make sense but I had no clue how to word it. Now I'll start with I have VERY LITTLE knowledge on string theory. I have a basic understanding though. So if our universe's spacetime is composed of these one dimensional strings, a plank length apart in all 3 (and more) dimensions. With these being so small I see them acting like a sheet. Just like the sheet I see from general relativity lectures. So that being said if I imagine a massive object on this sheet of strings I see them bending as they would, with a lot of bending near the center and less the farther you get away. But what is the elasticity of these strings? And does it have anything to do with anything? If the strings have any elasticity in them they would be resisting the objects. Does this give it mass or have anything to do with the higgs field? Do these effects by objects vibrate the strings and produce a higgs boson? I guess for the objects to really affect the strings it would need mass befor it did so, so i guess that was a dumb point. Honestly I'm kinda high, and I am just imagining strange thought experiments, so if none of this makes sense at all please tell me lol.1 AnswerPhysics6 months ago
I’ll start by saying I have a VERY limited understanding of quantum mechanics but the one thing that has interested me very much was the double slit experiment. I’m referring to the experiment where scientists were going to turn on the detectors to determine where the particle was during the experiment only to find that the particles collapsed before they could do so. It makes the particles seem like they have a mind of their own and will decide something before we have ever decided. I’ve always wondered if you could give the particles a paradox. Perhaps “I will ONLY turn on the detectors if I see the wave pattern” then if they collapse they will have to do so forever without ever being detected and if they don’t then you could turn on the detectors to detect them? I don’t know. It’s all very confusing and I hope this makes sense.2 AnswersPhysics9 months ago
I was watching micro organisms and looking at how they reproduce asexually and I was really interested on how can they just create an identical copy so quickly and then I thought it must be because they are so much smaller. It would be impossible for macro organisms to do this because of how many materials are needed? I get it could also be to promote diversity but I am just interested in if complexity behaved as a parameter on the process2 AnswersBiology9 months ago
So I know that the existence of virtual particle pairs at the event horizon cause Hawking radiation and it takes about 10^67 years for a black hole to evaporate but what happens at the end? Does the singularity just fizzle out of existence or does it end in a massive explosion that put supernovae to shame. Or is it something completely different entirely?17 AnswersAstronomy & Space9 months ago
I recently asked this question and it didn’t get much attention so I thought I’d ask it again. As I’m studying physics and quantum mechanics one of the most interesting topics to me is void. It got me thinking. What would a universe of all fundamental constants equal to 0 look like? Would it be void? Would it even be a universe? If an infinite multiverse existed with different fundamental constants always being tweaked you would expect there to be an infinite amount of these nothing universes alongside an infinite amount of matter filled universes. In the grand scheme there would be an infinite everything and an infinite nothing. Idk I thought this was an interesting question that’s why I wanted to ask it again.3 AnswersPhysics10 months ago
So I know at a glance that’s a stupid question but I’m just starting electricity and what not in physics and the striking resemblance of Coulomb’s law and Gravity has me thinking. Coulomb’s law states particles can both be attractive and repulsive because the universe has two different charges. Gravity is always attractive because there is only one type of mass. Now I’m picturing dark energy which I’ve only really been introduced to as a sort of “anti-gravity” this had me thinking that maybe there were actually two different “charges” to gravity and maybe it could be repulsive as well for some reason. I guess this would mean there would have to be a different form of mass? I also know that I have almost no understanding of relativity and am still stuck with a Newtonian view. I know to those who are more advanced with physics this is probably a dumb question but I just like asking them whenever they come to mind.4 AnswersPhysics10 months ago
If an infinite multiverse exists, would universes comprised of cosmological constants all set at 0 be basically nothing? Could “void” just be considered universes with no cosmological constants? There would be an infinite amount of them so therefore infinite everything and infinite nothing. Holy **** I’m high af3 AnswersAstronomy & Space10 months ago
So I’m no expert on astronomy by ANY means. But when I think about the correlation between space and time when looking at distant galaxies I asked myself if it was possible to see the same galaxy but at different times. Basically what I’m saying is that if you were to look at a galaxy 7 billion LY away you see it as it was 7 billion years ago. Now let’s say you look at a galaxy 12 billion LY away, could it be possible you are looking at the same galaxy but at different points in time? Could some older galaxies actually be the same galaxies as younger ones? I hope I worded that easy enough.10 AnswersAstronomy & Space11 months ago
When mass is converted into energy where does the gravitational effect go? Could dark energy be involved?
So I was wondering whenever mass is converted into energy where does the gravitational effect go? If thinking in terms of general relativity where gravity is the bending of space time, when an object loses mass and is converted into energy it’s gravity must also change. If that’s the case I’m imagining the fabric of space time being bent by gravity and once it is converted the space time is launched back to equilibrium and upwards resulting in a repulsive force. Could that be dark energy? On a massive scale of billions of stars in a galaxy fusing hydrogen and converting mass into energy there would be a large repulsive force emanating from it maybe that could be dark energy? I don’t know I’m not too well versed on it but It’s just a thought I had.4 AnswersPhysics11 months ago
So I was wondering would the speed of light slowly decreasing explain the things we see? Like red shift and the rapid inflation?
So I was driving the other day thinking about space and I was wondering... if the speed of light were different at the beginning of the universe it would explain why the universe expanded so rapidly, and while it has aged the light speed has decreased. As I have it more thought I thought about how the universe would look if light was slowing down. I realized it would kind of explain why the universe looks like it is expanding. As light gets slower a light years distance is changing and getting smaller, which would make things appear as they are farther away. And maybe the distant objects we see are red shifted because light in their time was faster than is is here and when we see it turn red it’s the light getting slower and thus it’s wavelength longer. I don’t know if any of this makes sense but maybe if it’s somewhat accurate it would overrule the assumption made by Einstein that light is a universal constant. I just want to know anybody’s take on it so please discuss it with me. Thank you!3 AnswersPhysics2 years ago
