    At the singularity there’s infinite density which has enough gravity to account for gravitational lensing when combined with the known amount of matter and mass of the galaxy. There’s no need for invisible matter. It’s all there in and around the singularity. What’s not being taken into consideration is the variable of the measures of time and distance the farther away from a singularity it is. It is actually changing the speed of light from place to place. The speed of light is faster in the outer edges than it is near the center causing the lens effect just like a glass lens that slows down light near the center and allows for light to travel faster in the outer edges.

    Consider the notion that the universe might not permit true infinite parallels. Within the intricate fabric of space-time, the idea arises that even parallel paths could converge or diverge due to the inherent complexity and limitations, challenging the notion of endless parallels in our understanding of the cosmos. Exploring such limitations could open up new avenues for comprehending the fundamental nature of the universe.

      Apart from the electrical advancements throughout ALL civilisations in history and the many cover ups thereof. I too think there is huge time delay or lag that will catch up like a massive wave or burst, but sure. I think it's due to using electricity by 'forcing' too much power out of the current. The energy released isn't flowing back naturally. What I'm saying is - you can't expect having a balanced system by taking a too large portion out at once in a short period of time.
      If we want to harness good clean and sufficient energy - we should piggy-back on earth's ecosystem in harmony, instead of crowbaring our way through for gains, like machetes in a jungle. Go with flow always applies. In this case.. Amplitudes were far too high and there is the time lag... Might be cause electrical technology has been scaled down another level. And looking back in history - that's when multimillenia empires 'seem to vanish:..

    What if the shape of the plane that space time exists upon was non-contiguous?
    Non-linear?
    Imagine viewing the largest fields as a quantum entangled (translucency?) shape ?
    I may not have a correct yet?…
    I’m trying to imagine looking from the inside of a tiniest quantum element outward as I were pointing a flashlight out…
    At the same time, needing to know the point of entanglement, that would converge all of my calculations.
    Am I proposing that there’s a possibility of an equal concurrent force on the shape as a force?
    The entangled shape would flip the switch on everything the same way that switching from positive to negative numbers would change Jim Matric numbers/forces/effects?
    I’m no scientist.
    No mathematician.
    Simply an artistic thinker.
    Is there any reason not to ponder my thought as a new perspective on solving the equations?

      how do you explain the difference in force of two objects falling at the same speed. if gravity is a equal force. the difference in mass under equal force should react differently in motion not just their difference in increasing force. but if gravity was the path of least resistance . the result would be as observed.

    I’m sorry, but Einstein notation is not “brilliant“; it’s annoying as hell. Just drop the me and new all together and you have an operator applied to its variable performs summation. It’s either a linear operator a multi linear operator (tensor), or some other kind of nonlinear operator.

    Once you indulge into Einstein's maniacal ideas, you lose credibility.
    The fourth dimension -c dt lacks any plausibility because time related to material events, not to dimension.
    Newton's second law F= m.a already accounted for acceleration which is spacetime variable.
    Nobody could use or benefit from Einstein's relativity, special or general. Lorentz Transformation accounted for the kinetics of constant c, variable v.
    Because Einstein's relativity lacked causation, relied on Euclidean geometry it must not apply to time because time is eventual, originated from material thermodynamics, not Euclidean geometry.

      Newtonian physics works, in the sense that it allows you to calculate some quantities in a useful way, but the metaphysics is completely impossible. How is it that a rock flying through empty space can recalculate its own momentum to arbitrary precision in zero time?

      Classical mechanics was founded on empirical observations based on sensible collected data about celestial motion. The singularities issue concerned hypothesis that were never encountered in practice.
      For example, one cannot assume that gravity at the center of Earth is infinite by putting r =0 in Newton's law of gravitation.
      In the case of Einstein's relativity, you would be mocked by any practical physicist if you think that Einstein was a capable scientist. Einstein squandered his life in delusion that attracted detached theorists.
      Back to your puzzle of memory of momentum and inertia in remote space. You would not solve that puzzle by relying on relativity. You can only solve that puzzle either by inertial gyroscope or statistical gyroscope using memory flash storage.
      Here is why no one believed on trusted Einstein to solve any realistic puzzle. Gravity is generated around and in proximity of a star or a planet. That means far away from that star or that planet, you got no gravity. So, how do you curve spacetime when and where gravity of one star or one planet has no effect.
      The reason why you cannot sell Einstein relativity to a numerical analyst is the time variable. Einstein delved into spacetime delusion without accounting for the event that initiate time or the location that surrounded events.
      By metaphysics, oh my God, that is not where science ends. That is were delusion thrives.
