    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=mc^2^. Energy distorts spacetime the same as its equivalent rest mass.

      Hartley has a very simple way of viewing this, see photo from his textbook “Introduction to General Relativity” photo

      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.

        In physics theory doesn’t mean some random guess. Theory means it has been experimentally validated.

    i think this is a little too vague to answer on its own

      Can a relationship be established between time, space and energy ?

      source
      • lime@feddit.nu ⁨4⁩ ⁨days⁩ ago

        that’s the same question. and by asking it, you have established a relation. so yes!

        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.

    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.

    I’d like to add 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. ➹

      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.

    Yes.

    But what’s the context?

    source
  • AnarchoEngineer@lemmy.dbzer0.com ⁨4⁩ ⁨days⁩ ago

    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

    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.
