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.

  • 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.

  • 10:19 "Well the answer is, absolutely" Turn on english subtitles in CC: "The answer is lol no". nice easter egg xD

  • Gravity is an emergence caused by time- subtracting mass. Subtracting mass in the sense that any matter has some sort of internal clock (rotation, vibration, etc.), but it collapses back into the probability field when it is not currently in the wavefront. That action of collapse is experienced as gravity's phenomena, like capillary action on a temporal laminar flow of being, back into probability.

  • first of all, you don't travel through time at the speed of light because you always travel through space-time at the speed of light, two very different things secobd of all, the equivalance principle says "you cannot distinguish between being inside a constantly accelerating rocket (9,8 m per s^2) and standing on earth" meaning the earth is accelerating and not you towatd the earth (although you're in in inertail motion you're accelerating - changing your vector as well due to the curvature of space time) pbs space time 👎

  • How can light be constant if it slows down in fluid and gas?

    Mr XMr X14 ชั่วโมงที่ผ่านมา
    • light enters an atom light hits the electron/electrons electron starts oscillating - dancing while creating its own wavelenght this electron wavelength is merging with light while creating a mutual wavelenght this merged wavelength is always traveling slower than the speed of light photons are absorbed by the electron and then re emitted by the electron again once the electron hits the ends of the obstacle - the end of the medium

      ??5 ชั่วโมงที่ผ่านมา
    • 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. Just a thought

    mytube1000javedmytube1000javed19 ชั่วโมงที่ผ่านมา
    • each tick is causing a mechanical disproportion, very tiny but over time this disproportion is there so you are getting a slowed tick after a certain period of time even if you don't move your clocks to anywhere the best clocks is the cesium atom it has 55 electrons confined in perfect stable "orbit" so they are perfect for measuring time or any disproportion in time

      ??4 ชั่วโมงที่ผ่านมา
    • Because time itself slows down. If the clock ticks once per second but a second isn't the same everywhere the clocks run at different rates, no matter the mechanism.

  • 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.

    Edward GormleyEdward Gormley2 วันที่ผ่านมา
    • This isn't new. This is just general relativity as it has been for over 100 years. The clocks on airplanes are _faster_ due to gravitational time dilation. And _slower_ due to relative velocity. The experiments agree with the theory.

  • 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.

  • So does this mean that time stops at the heart of a black hole? Or that there is no time in a black hole? To a lesser degree, will I live longer because my home is 200 feet below sea level? Discounting all other variables of course...

    Aleph NaughtAleph Naught5 วันที่ผ่านมา
    • @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.

      Narf WhalsNarf Whals3 วันที่ผ่านมา
    • @Narf Whals Damn, I was hoping for a year or two lol! Maybe I need to go live in the Kola superdeep borehole! So time slows only from the point of view of a distant observer. Does this mean that if I were positioned near the event horizon of a black hole, I would not perceive that my life was longer? Seems to make sense, since perception is relative to the observer.

      Aleph NaughtAleph Naught3 วันที่ผ่านมา
    • From the point of view of a distant observer time stops at the event horizon of a black hole. You will live a very tiny amount longer 200ft below sea level. Perhaps a second.

  • 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.

Distance and mass would equalize the position of the planets and the shape of the orbits of lesser masses such as our moon. Just my thoughts.

      Mathew GonzalezMathew Gonzalez9 วันที่ผ่านมา
    • @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?
