Energy bends spacetime, just like matter. Is that what you mean?
That’s an important link. How does that happen ?
Through mass/energy equivalence, E=mc2. Energy distorts spacetime the same as its equivalent rest mass.
To clarify, energy isn’t a “thing” that exists. It’s a property of matter, and so is mass.
So spacetime are only related in that matter exists in spacetime, and can influence it in ways we don’t (or at least I don’t,) really understand.
Thanks for that link.
Energy is not only a property of matter. Photons have energy, no mass, and are not matter but in fact force carrier particles.
Yeah, that sort of depends on the level of physics you’re talking about. regardless, it’s still a property of stuff even if that stuff is not always matter. if you want to go off on the weeds on that, go for it.
even so, energy is not something that exists, but a quantified attribute of things that do exist.
I don’t think through is the right term.
Mass distorts spacetime because that’s a thing that mass does, we can’t explain it any better than we can explain WHY apples fall from trees, we just have very detailed models for. HOW it works, and anything that has energy bends spacetime in the same way that mass does.
Don’t understand this bit.
the simple forms of conservation you probably learned in school are not entirely accurate. you probably learned that neither energy not matter can be created or destroyed; whatever you do, the mass you begin with will be the same as the mass you end with, and the same is true, separately, for energy. that’s not actually true; mass can be converted into energy, and vice versa. the correct form of conservation is that the combined mass-energy is constant. mass can be destroyed, but only if a proportional amount of energy is created. the coefficient of that proportionality is the square of the speed of light. that’s what E=mc² means. that’s how nuclear weapons work, and why they’re so powerful. c² is obviously a pretty big value, so when a small amount of matter is destroyed, it creates a large amount of energy
similarly, energy can be converted into mass, but doing so makes it much “smaller.” c² units of energy will become 1 unit of mass. and mass, of course, interacts with space-time
This is a very interesting theory.
You’re on the right track.
Mass is a property of matter, they’re not the same thing.
A water molecule is the same matter as two hydrogen atoms and an oxygen, yet the molecule has less mass. The difference comes from the energy released when the molecule is formed. Fusion is the same, forcing two atoms together releases a neutron with lots of energy. Same matter, less mass.
It’s the opposite with fission. One atom splits into two and two really fast neutrons, and the total mass is less than the original atom. The matter isn’t destroyed, but some of its mass is converted into energy.
Matter can be destroyed by annihilating it with antimatter, but that hardly counts because we have to make the antimatter by turning energy back into mass and that also creates an equal amount of matter.
In plain terms, energy has gravity.
Energy has gravity ??
What I never understood is why the electric field doesn’t distort spacetime more than gravity. The force between 2 electrons is like 4*10^42 times stronger than gravity. So a tiny electric field should cause the same spacetime bending as a massive object.
It does. The energy density of the em field will contribute to the stress-energy tensor that changes the metric of spacetime.
Though the force itself is irrelevant
Though the force itself is irrelevant
But force is a measure of the rate at which energy is transferred over a distance.
So if one force is greater than another and the distance is the same, then the energy is greater in the case of the greater force.
True. The em field is significantly more energetic, meaning that it contributes more to the stress energy tensor than the force of gravity
But recall that the force of gravity is the momentum change “due to” the curvature of spacetime. The fact that the force of gravity can bend spacetime at all is a really weird second-order perturbative effect.
These perturbative effects are typically described with a quantum field theory, but gravity has been thus far notably difficult to quantize.

But didn’t you just say that the electric field curves it too?
Hartle has a very simple way of viewing this, see photo from his textbook “Introduction to General Relativity”
One thing to remember is that GR is still just a theory with a substantial lack of experimental proof, but the maths does work out quite well with it.
I’m not sure what your definition of experimental proof is. There have been many experiments to test General Relativity over the past 100 years. As far as I know none of those experiments have found significant disagreement with the theory.
Here’s a paper about testing einstein’s theory:
https://arxiv.org/pdf/0806.1731
It is an older paper, but aftet a skim the only significant missing experiment is LIGO. At the scales which GR is fundamentally concerned we simply do not have sufficient data or technology to test.
If we had tested everything that could be for GR or it had no contraditions we wouldn’t be creating modified theories of gravity or proposing new constants to try solve things, or trying to come up with some quantum theory of gravity.
The Stress Energy Tensor is what you’re looking for. It is directly related to curvature, but beware, the explanations of both curvature and the stress-energy tensor are going to be difficult to parse if you aren’t familiar with tensors and their notation yet
I’d like to point out that it is suggested that information influences spacetime, too. That is, your RAM gains mass as soon as you boot your computer. It bends spacetime a tiny bit more if information is stored on it. So every trait of matter within spacetime turns out to be interconvertible:
Mass ⟺ Energy ⟺ Information ⟸⟹ Mass.
More craziness: In expanded spacetime, the amount of information on your RAM is decreased. With the energy you’re pumping in, it could store more.
Even more craziness: Information could be the foundation of spacetime, building it though quantum entanglement. (ER=EPR conjecture, Mark van Raamsdonk)
In expanded spacetime, the amount of information on your RAM is decreased. With the energy you’re pumping in, it could store more.
If that’s the case, we should start building RAM in a different way: In such a way that this isn’t just a ‘could’ but a ‘can’.
Information could be the foundation of spacetime, building it though quantum entanglement. (EP= EPR conjecture, Mark van Raamsdonk)
But in my theory, it isn’t information. It is will power that is one the foundations, while information is just a property of will power.
No, fear is.
But fear fears information…
It’s octanions all the way down anyway.
i think this is a little too vague to answer on its own
Can a relationship be established between time, space and energy ?
that’s the same question. and by asking it, you have established a relation. so yes!
How so ?
you put the words in the same sentence, hence you have created a relation between the words.
e=mc^2
So
c=√(e/m)
Or actually do calculus but screw that let’s just speculate that a photon having a lessr infinite energy is equivalent to a lower speed of light. Therefore space has shrunk or time has expanded or the opposite or whatever.
Can energy be associated with/related to spacetime ?
Yes.
Einstein has explained it with his “general relativity”.
No, it is not easy enough to explain it here. Try the existing study material about the topic.
Yes.
Energy warps spacetime just like mass.
But what’s the context?
Only if their parents fucked
Space has vacuum energy or ZPE (zero point.)
Quantum mechanics suggests this should be mind-blowing and enormous. We’ve only managed to detect ‘weak static.’ some are still hopeful, others are just sad.
Absolutely, energy goes where attention flows, if you are out of the moment in spacetime and somewhere else, say if you have been brainwashed or something, and your mind is constantly elsewhere you cannot properly focus your energy, when that happens you can’t properly grow in an organic manner to a fully blossomed human. When that happens en masse, chaos ensues and certainly changes things in the time line, people cannot focus on being their best. I’m not certain if people actually have the power to effect time in that sort of energy sense, perhaps though that all of the tribal ceremonies and gatherings and things like that of the past were not just for having a party. A more metaphysical angle I guess.
Woo boy.
Zzzzz.
Wow, you described me spectacularly :)))

That’s a significant achievement, being comfortable with who you are. But you were in the dark for several decades ??
Sure, dismissal and outright denial can put you in dark places, alcoholism for a lot of years, other drugs, just doing nothing. In the dark metaphorically speaking.
