Does Time Cause Gravity?

Sign Up on Patreon to get access to the Space Time Discord!
We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments. But I never explained WHY or HOW gravity causes the flow of time to slow down. And I’m not going to explain it now - because in a sense it’s not true. Gravity does NOT warp the flow of time. It’s the other way around - the warping of time causes gravity.

    So to achieve anti-gravity all one needs to do is increase the rate of the time dimension of an object.........piece of cake :p. Seriously though if we could alter that field by 1/1,000,000,000 we could anti-gravity to achieve orbit to do that though???? What causes that specifically besides from the observation it occurs around massive objects, what in the massive objects is doing this and can it be replicated artificially without all the mass/energy. answer that and we will have warp drives.

    Yes! Just in the same way that physics differs from each geospatial astrocosmological points of reference from each parts of the galaxy and beyond! This in itself would expose and unravel that of dark matter given one a clearer understanding of a 5th and indeed a 6th force from being concealed as just a scotoma from the schools of astrophysical faculty hence the term 'university' thus hushing curious scientific minds within the foundations of mainstream astrophysical academia retrospectively from learning more. Which only serves those to hypothesise over as it currently is as just being treated as just mere theoretical universal grand assumptions subject to scientific scrutiny and conjecture that it is currently!

    Oh Hey! this almost perfectly matches a theory I came up with myself about there not really being gravity but that time warps when matter gathers together. and my explaination about why things orbited rather than the boats in the river example was if you were in a wheel chair with one side closer to the planet. that side would experience time slightly slower so the inside wheel would turn slower than the outside wheel causing the wheel chair to slowly turn. My friends said I was crazy! although maybe that's because I also theorized that perhaps anti matter had the opposite effect and could effectively form an anti gravity field or and area where time flowed in reverse. I theorized the reason we havent seen that property of antimatter yet is because you would have to gather enough antimatter together to locally overpower not only the gravity of the earth (which would be exerting a time moving forward effect) but also the sun (a larger background time moving forward effect) and outside all of that. the power of the super massive black whole at the center of the milkyway galaxy (which is once again exerting a incredibly wide range time moving forward effect) I stopped looking there because sources of gravity beyond the supermassive black hole is beyond my knowledge and lets be real is probably impractical to think about anyways.

    Great video. There is something that is not clear to me, however. Due to the equivalence principle, as I understand it, the person in the box should not be able to tell the difference between the acceleration due to gravity and the acceleration due to the box being pulled from outside. However, what if there were identical, super accurate/sensitive clocks placed at the top and bottom of the box? In the case where the acceleration is due to mass (gravity), the clock at the top of the box should measure time as moving more quickly. But, would the clocks read the same difference when the box is being pulled from the outside? If so, what causes that difference? If not, then could the person tell the difference between the scenarios just be reading the clocks?

    Particles are harmonic vibrations riding a pilot wave. The ripples of time affected by the slowing of it's base vibration cause a wave to move towards it. Gravity is an attempt to consume energy to get back to 1

    If we are going to say that "gravity" isn't what is warping space-time (but that it is the pseudo-force accelerating masses towards the center of gravity a la the magnetic force) it seems like we need to have a name for the "space-time warping force" that is the "true" force. I propose the "exigency force" as this conveys both the important and existential nature of the force as well as the urgency relating the the time component. Anyone agree/have a better name?

    Its not speed of light. Its a maximum speed of change of information. Like universe maximum tact / frequency. Like maximum speed of computation in space. With this maximum speed light travels, fotons travels , probability function collapses and time runs. Gravity is apparently acceleration for energy and mass cumulation. But what is accelerating and where is not clear. Einstein deceived the world for 200 years until it comes clear its not speed of light but maximum clock / change of information in the universe. E = mTc2.

      It doesn't. "light slows down in a medium" is just a shortcut for the complicated wave mechanics that goes on. The medium emits light in response to the light passing through it. Those waves add together and the result can travel slower or even seem to be faster that c. But each individual wave travels at the speed of light in vacuum. See group velocity and phase velocity for more detail.

    I always thought the best way to travel faster than the speed of light is to have a device make a warp or like a black hole in front of your ship so your ship can continuously fall into and I think something as small as a dime could pull something as big as the Empire State Building.

    I'm certain there are a lot of people who know an ungodly amount more about this than I do. I dabble but am mostly ignorant. I'm just curious though. I guess the question I'm curious about is "Is this time gradient a plank unit over distance... not quite right... is there a smallest difference this effect would exist like over the plank length. If it exists over a smaller distance than the plank length or larger how would that effect which particles could experience it... and also if it is limited by the plank length in the increments of the gradient would that make gravity quantum? I'd assume that if space is limited to increments of plank lengths then the conversion between space and time would be limited by that as well. Just silly thoughts that pop up in an mostly ignorant mind watching videos like this. If anyone has the answers in a slightly layman point of view I'd really appreciate any response.

    Well that answered what dark energy is for me. Mass causes time to slow down, like friction, and dark energy is the atmosphere that this friction is interacting with. And if there is no mass dark energy can expand faster / time can go faster, Because it wants to expand does that mean that dark energy is under some kind of pressure. So I guess the universal expansion is just a dimensional internal pressure. Everything wants to pop and matter is slowing it down. Also it explained why our galaxy and solar system are in spirals just like the boats.

    I feel like a lot of physics dealing with _c_ makes more intuitive sense when you think about it as the speed of causality. It's then obvious that massless things like EM waves & gravitational travel at the _speed of causality_ in a vacuum. It also makes it easy to see how mass/energy impedes this, like a viscosity scalar.

      @Aleph Naught The borehole also won't buy you much more. To put into perspective. The core of the earth is about 2 years younger than the crust. Over its 4.5 billion year age. "If I were positioned near the event horizon of a black hole, I would not perceive that my life was longer?" correct. Local time is always 1second per second. Only when you compare it to someone else's time will you notice a difference. The same is true for time dilation from relative movement. If you are moving relative to each other you only see the other person's clock slow, never your own.

    I met Stephen Hawking at a time I was looking into what seemed to be serious research on anti-gravity. I asked him whether he believed anti-gravity would prove to be a force we could use, and his answer at the time puzzled me a bit. He said (the quote is close, but certainly not exact, and came through with his speaking device) "Anti-gravity would require the ability to reverse time, and I do not believe I have ever met someone from the future." Your clear explanation elucidates exactly why he said that.

      @Mathew Gonzalez Because General Relativity is still in complete. while it can explains many problems when we treated gravity as a force,GR however doesn't work for tiny scales like atom and particles. For example for the case of a black hole, all matter were compressed into a single point with no size that we called a "singularity". , this is where the math of GR blew up to inifinity. and as we knows so far,nothing in the universe is infinite,this means the theory has been breakdown. even theory of quantum mechanics still doesn't work. This is why scientists came up with theories of quantum gravity but so far, none of them has been confirm to be true. and we still have a lot unanswered questions like why mass curved space-time at the first place or if time itself is curved by mass,then why electron can exist at mutiple locations simultaneously... because simultaneity doesn't exist if space-time were curved. we can see that quantum mechanics and General Relativity doesn't agree. a new theory of quantum gravity maybe fit gravity into quantum picture and explained all of those questions. I hope that we'll figure it out soon !

      @Bồ Công Anh ahhh , well it was always explained horrible to me then in the past because it was always described as mass being the controlling factor of gravity. But now if I understand it right it’s time that is the controlling factor and mass is simply just a factor with in that . But now I’m confused on how a graviton might fit into this? Why do we still need the existence of a graviton to explain stuff?

      it's Einstein General Relativity it was published for a century but most of the explanation on internet only focus around space curvature on rubber sheet,but that analogy is completely wrong and not actually the describes main cause of attraction.

    Since a photon is outside of time (time = 0), doesn't that solve the double slit causality issue?

    So a 0mass - theoretically - object moves at speed of light, this means that there is a possible mass value in which an object moves at 0% of speed of light. What would it mean for an observer, death?

      For a massless particle there exists no reference frame where it doesn't move at the speed of light. For a massive particle there exists a frame where it doesn't move at all. The "rest frame" where it is at rest. And _no_ reference frame where it moves at the speed of light. Anything that moves at the speed of light has no rest frame.

    06:22 - I can't believe your very well educated compatriots in the production of this video didn't notice they misspelled "Financial" as "Finanicial" (upper right corner) in what should have been "MID-DAY FINANCIAL REPORT", but there it is for the world to see. I was sure you guys had proofreaders... or editors... or somebody who's supposed to notice these things.

    How much does the fact that we are on the rotating earth, which is moving around the sun, which is moving around the Milky Way, affect our perception of time? Is there time at all out in space between galaxies almost free from gravity? How much quicker would all the sand go through an hour glass? Probably less than an hour

    Does time any ways effects gravity? I will say no. Time coexist with gravity, time creates dimension with gravitational rise and fall. Each planet or star has it's own gravitational reserves and then exists galactic gravitational reserves even though they coexist they don't interfere with each other, the same way time exists for each individual planet or star and galaxy, space in between galaxies has weak gravitational force and is not evenly distributed some areas of the space contain more than other.

    does time cause the expansion of the universe. is time the dark matter everyone cant see.

    Then how gravity varies from planet to planet?

    I guess the answer is yes .but it works because My God the God of Abraham Isaak and Jacob wills it to that way.
