Gravitation is directly connected with the flow of time. Stop of time means collapse of a gravitating bdy.

The statement doesn't make sense because it doesn't define what gravitation is supposed to be, nor how does space and time transform. Time is one spacetime coordinate. Gravitation, in general relativity, is defined by the property that spacrtime remains invariant under general coordinate transformations, not only of time but, also, of space. What distinguishes time from space is the signature of the metric. That's all that's necessary and sufficient.

Time can’t ``stop" if space can’t and vice versa. That’s where general relativity is useful: It establishes the conditions under which space and time can ``stop". This is when singularities can appear.

So it would be a good idea to learn general relativity-from textbooks, not popular literature.

Siddharth Rana,

Gravity is not time but affects time in a way that where gravity is stronger,time passes slower,and this has been taken into account in the GPS else GPS applications would fail.

Physical laws do not inhibit time travel as clearly shown in Einstein's general theory of relativity,and the question is mainly technological especially that Hawking's conjecture has been considered mistaken by most physicists. In this short YouTube video, Theoretical Physicist and Superstring Theorist Professor Michio Kaku expatiates on how time travel to the past is possible and should be taken seriously.

“Gravity is Time; Time is Gravity (-Hypothesis)”

- that isn’t of course, correct. However the objections to the “Hypothesis” in the posts on the thread till now, since are in framework of the GR, which really is scientifically rather strange theory, are, correspondingly strange as well; including since the hypothesis is essentially is in full accordance with the GR – the GR is based on the main postulate that the objects/events/effects/processes in observed experimentally gravitationally coupled systems of bodies are determined by interactions in systems “mass-spacetime-mass”,

- and so time in this [curved] spacetime, at least partially, “is Gravity”.

As, say,

“…Time can’t ``stop" if space can’t and vice versa. That’s where general relativity is useful: It establishes the conditions under which space and time can ``stop". This is when singularities can appear. So it would be a good idea to learn general relativity-from textbooks, not popular literature...”

- yeah, all that is really in the textbooks; where yet Newton definition of “time” as it is “true and mathematical time, of itself, and from its own nature flows equably without regard to anything external” – as that most of humans percept the fundamental phenomenon/notion “Time” instinctively in all times well before Newton and till now, principally is postulated in the SR/GR also, with only “correction”: that this flow regards to external, when can be “dilated” in moving frames or in gravitationally coupled systems.

However really, as that is rigorously proven in the philosophical 2007 Shevchenko-Tokarevsky’s “The Information as Absolute” conception, recent version of the basic paper see

https://www.researchgate.net/publication/363645560_The_Information_as_Absolute_-_2022_ed

- where the fundamental phenomena/notions first of all in this case “Matter”, “Consciousness”, “Space”, “Time”, “Energy”, “Information”, which are fundamentally completely transcendent/uncertain/irrational in mainstream philosophy and sciences, including for the GR author, are rigorously scientifically defined ,

- and in the informational physical model, here see https://www.researchgate.net/publication/355361749_The_informational_physical_model_and_fundamental_problems_in_physics it is rigorously scientifically proven that Matter’s spacetime is the fundamentally absolute, fundamentally flat, and fundamentally “Cartesian”, (at least) [4+4+1]4D spacetime with metrics (cτ,X,Y,Z,g,w,e,s,ct).

The spacetime really by definition of “space” and “time” is fundamentally nothing else than empty container, where fundamentally no of the space cτ,X,Y,Z,g,w,e,s dimensions, and time ct-dimension, can “flow”, be “contracted”, “dilated”, “curved”, etc., including in the spacetime of course, fundamentally no any singularities can appear.

The main GR postulate above really is nothing else than some transcendent/irrational – and really fundamentally wrong – proposition of the author, who had only some transcendent imagination about what are “Matter/matter”, “Space/space”, “Time/time”, “Energy/energy”; however till now the correspondingly strange SR/GR claims are rather popular as, say, that

“…Physical laws do not inhibit time travel as clearly shown in Einstein's general theory of relativity,….., Theoretical Physicist and Superstring Theorist Professor Michio Kaku expatiates on how time travel to the past is possible and should be taken seriously…”

- while really, of course, any – though yeah in the GR “clearly shown and be taken completely seriously” – completely fantastic “time travels” fundamentally cannot, and so don’t, exist.

Gravity is, of course, fundamentally nothing else than only some fundamental Nature force, which in a number of traits is similar to the Electric Force; more about what really Gravity is see Shevchenko-Tokarevsky’s 2007 initial model of Gravity and Electric Forces in second link above, section 6. “Mediation of the fundamental forces in complex systems”. Moreover, it turns out to be that at least also Nuclear Force acts in Matter by the same scheme as Gravity and Electric ones, more see

Dear Siddharth Rana

Try what you described outside the Earth, in its zero gravity space! Gravity affects the measurement of time... It's not gravity that actually does it, it's what the gravity is caused, and its inseparable from what's in it...

No matter how far from reality what you describe is, because with this you can perfectly deny the image that led you to think this!

Good solutions lead to the goal, bad solutions have the opposite effect.

Regards,

Laszlo

- looks as rather strange claim. The fundamental Nature Gravity force acts as that gravitational charges “gravitational masses” constantly always radiate Gravity mediators, which form what in Newton mechanics is called “gravitational fields”; since the mediators are stable, the fields, in principle, exist on practically infinite distances;

- and if in a field some other gravitational charge [a body] is placed, some force acts on this other charge – and the other charge’s filed impacts on the first one of course also.

Including, of course, that is in the space outside Earth, just so Earth satellites, including, say, Moon, don’t move to somewhere, but move only on their orbits.

At that the fields affect clocks that measure the time intervals, because slows intrinsic processes rates in the clocks; and not only - in all/every bodies that compose some gravitationally coupled system the intrinsic processes are slowed, just so in closed systems the energy conservation law acts – and just so the GR isn’t correct theory since in it the energy conservation law is violated; including the “GR gravitational time dilation” value that is predicted in the GR – though really this effect – see above - exists - isn’t correct.

More see the SS&VT initial Gravity and Electric Forces model in the link in SS post above or in https://www.researchgate.net/publication/365437307_The_informational_model_-_Gravity_and_Electric_Forces ;

- including in the model practically for sure real value of the slowing of intrinsic processes is predicted, what is quite easily tested experimentally – see https://www.researchgate.net/publication/277710038_The_informational_model_-_gravity_a_next_experiment

The following preprint explains what gravity has to do with time

Preprint What gravitation really is

The answer is that gravity simply is a force field which modifies a cosmic energy field, which is related to the spacetime metric.
