Could Gravity Be an Effect of Mass Inertia in an Accelerating Universe?

Click For Summary

Discussion Overview

The discussion revolves around the concept of gravity potentially being an effect of mass inertia in an accelerating universe. Participants explore the implications of mass deforming space-time, the relationship between gravity and the universe's expansion, and the nature of energy in this context. The scope includes theoretical considerations and speculative ideas about the universe's evolution and the behavior of massive objects.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants propose that gravity could be a consequence of mass inertia in an accelerating universe, suggesting that gravity might vary with different stages of the universe's expansion.
  • One participant questions the current model of the universe, suggesting that it may not adequately explain certain phenomena and encourages exploration of alternative theories.
  • Another participant emphasizes that any new model must be able to make accurate predictions comparable to the current model, which is well-supported by observations.
  • There are inquiries about whether space-time slows its expansion when interacting with more massive objects and the implications of gravity depending on the universe's acceleration.
  • One participant asserts that a relationship between space, time, and velocity can only be expressed through a specific equation, questioning the validity of other approaches.
  • Another participant discusses the need for acceleration to produce effects similar to gravity, drawing parallels to classical physics problems.
  • There is a suggestion that dark energy could be derived from the current incomplete understanding of the universe, referencing a specific book for further exploration of these ideas.
  • One participant introduces the concept of entropy as a governing principle in the universe, discussing its effects on energy and the flow of heat.

Areas of Agreement / Disagreement

Participants express a range of views, with some supporting the idea that gravity may relate to mass inertia and others defending the current cosmological model. The discussion remains unresolved, with multiple competing theories and perspectives present.

Contextual Notes

Some claims depend on specific definitions of terms like "gravity," "mass," and "energy," which may not be universally agreed upon. The discussion also touches on unresolved mathematical relationships and assumptions regarding the universe's expansion.

What if...

Gravity is the consecuence of mass deforming space-time. But why mass deforms space-time?
What if gravity is the consecuence of mass inertia in an accelerated universe. I can imagine a universe expanding at an accelerated speed that is being deformed by the inertia of the objects with mass. So gravity depends on acceleration of expansion and could be different at different stages of the evolution of universe. For instance, what if quasars are supergigantic stars at a moment in what gravity had other value smaller than the current value (because smaller acceleration value) and a supergigantic star could exist without transforming into a black hole. Why there are not supernovas nor galaxies at same distance than quasars?
Can anyone calculate the acceleration needed to achive current velocity of expansion considering the universe an hypersphere? (This is for a constantly accelerated universe)
Can anyone calculate the slope of acceleration needed to achive current velocity of expansion considering the universe an hypersphere and a start of almost zero for acceleration at the beginning and the messured current acceleration at end?
Thanks for your answers :smile:

Pietro,
I like your questions. They show the absurdity of the current picture
of the universe. You may not lose your time to explore it anymore. You should rather look
for alternatives. One day you may have a good theory of your own.

The problem with discarding our current model of the universe, big-egg, is it makes testable, highly accurate predictions about a very broad variety of phenomena. Any replacement will naturally need to be equally (or more) accurate/useful.
 
Does space-time slow it's expansion when "dragging" more massive objects? Also, if gravity depends on the acceleration (or the velocity more likely here) of the Universe, then there may be areas of the Universe where a black hole is created, and then... all of a sudden there wouldn't be enough gravity to keep the black hole, and then what would happen? Would it pop back out as a star again?
I guess really in a sense you could view the "warping" of space-time as due to inertia; but you would be using a lot of the same units and measurements for your calculations, so I think you would just end up with very similar results.
 
You know what?

I can figure out why are you all so concerned about space-time?
You cannot relate the two without some velocity and if so
than what velocity it will be and more what would the relation BE?

I can tell you that this relation is only X=VT.
There is no other way to relate space, time and velocity if you're not making mistake.

Am I in TD where I can speak free my mind?

Rahmuss, you need acceleration to obtain a result similar to gravity. If you have constant velocity, then you can´t have visible efects. Is similar to what happens in regular physics problems. About "dragging" you are right, I think if we have an accelerated universe then we have a force driving the expansion and of course a work (or energy to use a more general term) that can be calculated. This energy must be obtained at expense of something, can anyone tell me at expense of what this energy is obtained?
I enjoy this discussions a lot
Thanks
 
Pietro,
I enjoy your questions.

“This energy must be obtained at expense of something, can anyone tell me at expense of what this energy is obtained?”

The dark energy can be obtained at the expense of the current incomplete picture of the universe. Answers to your questions you may find in the book Theory of Interaction the Simplest Explanation of Everything by Eugene Savov. In this book a complete picture of the universe is presented in the terms of its revealed all-explaining singularity free structure.
 
All energy in the universe is just mass ( much of it which is in the form of light) that is constantly being affected by the pricipal of entropy. entropy controls the flow of hot to cold, and the amount of disorder or chaos in a given system. entropy ultimately governs all electrical, chemical, biological (except for basic physical laws) occurrances in nature. The flow of hot to cold and the effect of complication or chaos increasing with time just as easily could have been the other way around: Cold to hot. But would we really know the difference if we were suddenly part of that world?
