Isaac Newton is best known for his theory of gravity. And yet, the great scientist also insisted: "ye cause of gravity is what I do not pretend to know.” In other words, notions like gravity, and force in general, are deeply mysterious phenomena.
In this episode of the Sheldrake-Vernon Dialogues, Rupert Sheldrake and Mark Vernon ask just what gravity might be. The conversation begins with a feature of gravity that is typically overlooked by physicists, namely that gravity has a speed which is far faster than the speed of light.
They consider how gravity might be linked to the notion of levity, a link that can be renewed again. Newton himself was inclined to regard gravity as the divine will in the cosmos and was also influenced by the belief in daemons, particularly the entity called Eros or love. These are go-betweens in the universe, in the case of Eros, attracting all things and securing the many as a whole. Panpsychism and final causes are other themes that arise.
Contemplating the mysteries of modern science, often hidden in plain sight, leads naturally to deeply meaningful considerations about the nature of the world in which we live.

There are 2 ligo detectors on earth very far away from one another. They observe things happening in the heavens and then measure the gravitational waves with ligo. Of course, the waves arrive at one detector, then are expected to arrive at the next (geographically distant) one, with a delay equal to the speed of loght. And that is exactly what happens and is measured as far as I’m aware. In fact I believe they are able to use this timing difference between the two to ascertain the direction the of the event. Someone correct me if I’m wrong.

@keithvertrees9008 11 дней назад

This is my understanding as well. When both LIGO and VIRGO have a detection they are sometimes able to alert astronomers to the general area on the sky, and they are then able to observe the EM emissions from the same event which arrive roughly at the same time. I don't know how to reconcile that with what Dr. Sheldrake is saying here.

@maxtroy 11 дней назад

@@keithvertrees9008 the whole ligo thing absolutely blew my mind. Veritasium did a video on it, the precision involved, what was it, the resolution in the detector was effectively 1/2000th of the width of a proton or something crazy like that? But yeah. I have to wonder, does Sheldrake actually keep up to date with all the latest advancements or is he so far down his own rabbit hole he only pays attention to theories and information that align with his point of view? It’s kind of disappointing because I really like a lot of what he has to say, but when you confidently say the things he’s saying here - when a layman like me who works a 9-5 seems know more about state of the art experiments in this area, well …

You can't measure anything that travels faster than the speed of light with a system that depends on the speed of light for the basis of it's measurement, the measured speed will only be show as the time dilation of the measuring system, as the event trying to be measured occurs in the future. Gravity influenced the future, but we can only see it's influence in the past, which we precive as the present.

I do not understand the issue here...the traditional reasoning is that the Earth is not feeling the Sun directly, but instead, it is moving through a type of medium whose form and relational quality is dictated by the Sun at an earlier time, and "updates" to this medium propagate at the speed of light. So the Earth is never reacting to the Sun directly or instantaneously, but instead to a past image of the Sun that was encoded into the geometry of local spacetime. The whole beginning of this argument has the air of an unfortunate misunderstanding stemming from a poor translation of mathematical ideas into natural language.

@timjohnson3913 14 дней назад

I agree with you, but it is curious that the force of gravity points to the instantaneous position of the attracting body, not the older position delayed by the speed of light (electromagnetic charges work the same way). In GR, a component of the calculation is related to the velocity of the attracting body, hence the force is able to point to the instantaneous position. One way to interpret this may be that the gravitational field itself has a velocity.

"Gravity acts as a final cause... it's attracting from the future..." [21:27] Brilliant! Teilhard de Chardin taught the cosmos is converging on God, his teleological "Omega Point", by an attraction which is the inverse of terrestrial gravity. His philosophy has always struck me as a recasting of ancient eros mysticism in naturalistic terms. More recently, Ian Barbour has argued that gravity, rather than entropy, is the cause of time (if time exists at all), and that the universe is becoming *more* structured, not less, at least on the large scale. Allometry, and in particular, Metabolic Scaling Theory in ecology, provides insight into how life may be understood as a gravitational phenomenon, by demonstrating the relationship of mass and space to ecosystems. Then there's Penrose/Hameroff's proposal that consciousness may provide a solution to the riddle of quantum gravity, through quantum interactions with the cell's skeletal microtubules. The universe, I'm convinced, is gravitating to God!

@lawofuniverserealityanalyt3199 4 месяца назад

But electromagnetism is known to be a stronger force than gravity? Electromagnetic attractor fields are nondual dualities of mind/logos and spirit. Mind is the electronic action the reaction of which is the spirit. Newton's third law, the law of the universe! This has its parallel mechanical solution in solving the problem of complexity in a transport network, an all-at-once nondual mind spirit duality.

While I haven't read the paper yet, I would think this is resolved just by introducing the gravitational field. We don't need to worry about gravity's speed because the gravitational field is already there. If you have an orbit with a gravitational field, it is stable indefinitely if you choose the right initial conditions. Only if the field changes would you have to worry about the rate of that change, which would probably be on the order of c.

@Reziac 10 дней назад

Someone once pointed out that if gravity were not (almost) instantaneous, by the time the sun's gravity reached the Earth, Earth would have flown off into space. And there'd be no such thing as captured satellites, because by the time gravity trundled out to capture it, it would have flown on past. Put that way, it seems fairly obvious. The idea that it's more of a ...container... fits that pretty well. Field effect, rather than a wave effect.

@CarsonBirdD Месяц назад

Haven't watched the whole video yet, and I am no expert, but based on the beginning, you're saying that if I shoved the sun, the gravitational ripple of the sudden and intense motion would travel to earth faster than the speed of light? That gravity can exceed the speed of causality? I mean, we have measured gravitational waves, and found them to propagate at the speed of causality, AKA the speed of light in a vacuum. It's not that light takes 8 minutes to reach earth - it's that events seem to only be able to propagate across space at the speed light also happens to travel. Definitely interested to keep listening...

@patrickquinlan3056 15 дней назад

We have waves on the surface of the sea but they do not indicate how fast the water is flowing. Gravity waves might travel at the speed of light but if gravity itself travels faster than light then the speed of causality may well equal the speed of gravity.

@tomszabo7350 15 дней назад

@patrickquinlan3056 Gravity has a gradient based on the inverse square law. It gradually gets weaker with distance. A gravity wave is a "ripple" in which the gravitational field rises and drops off sharply. It's exactly as if an object with mass were traveling at the speed of light such that its gravitational influence (spacetime curvature) was also traveling at the speed of light. Except the gravity wave propagates as a bubble from the source, so it's more like mass being blown out at the speed of light in every direction (what's actually propagating is inertial energy but of course this is equivalent under the principle of special relativity, which is why when you apply It to mass you get general relativity).

Well, in orbital mechanics physicists DO routinely use an adjustment of positions of objects to account for the delays of the speed of light. Further, recently the gravitation wave from the joining of two black holes coincided with the prediction from optical observations. This was from a distance of 1.3 billion years. Light and gravitation waves racing each other for 1.3 billion years and arrive at the same time is pretty convincing. I invented an instrument to directly measure the speed of gravity in 1970. It would not be terribly expensive to build today, maybe $10 million but the other evidence is convincing enough to not bother. There are a couple similar devices invented over the years and a few have been built and so far they detect no difference. I doubt if ancient philosophers have anything to do with this.

Limits of consciousness become the issue in this conversation. Reading about Kepler, the biggest takeaway for me is how deceiving the concept and quest for a sacred geometry can be.

Love is driving the universe because creativity is love. Of course we're talking about unconditional love. This idea of attraction is a bit off because we don't know if gravity is attractive or repulsive. Leveraging Glenn Borchardt's Neomechanical gravity, which is a "push" force resulting from aetheric pressure, we can also understand that baryonic mass is being pushed together by a force which is stronger in the cosmic voids, that force is a high pressure aetheric force produced by aetheric particles that are pushing baryonic matter together. No need for dark matter or dark energy. As for "everything would collapse without dark energy", well that presupposes that the universe is finite such that there is a center that is causing everything to collapse "in". However if the universe is infinite, no expansion, no inflation, no dark matter, no dark energy, just pushes coming from the voids, there would be no collapse, because no center. In fact, current measurements do not support universal expansion everywhere anyway. The idea of expansion is a hypothesis which is used to explain the redshift, which is the only real observation. Expansion has no shred of evidence supporting it. With the infinite universe assumption combined with the "aetheric pressure" assumption, we now have an hypothesis based on 2 variables rather than 4 (inflation, dark matter, expansion, dark energy). And the idea of infinite universe (macroscopic and microscopic) is consuponible with the idea that "its matter all the way down" ie, matter which is not solid, but full of space. You could also say its "holes all the way down", to stop arbitrarily just because of Heisenberg's Uncertainty principle and Planck's length is an artificial barrier. Matter and the motion of matter is all you actually need, and here we gain one more variable, that of the time dimension. If we consider that it's just matter and motion, then time is motion, we don't need a time dimension which is fundamental, throw out Einstein and Minkowski. So we get to a much simpler view of the universe which is as stated, consuponible with the view that matter and space are also infinite all the way down and all the way up. You then can explain everything using laboratory physics instead of proposing hypothesis like inflation, dark matter, expansion and dark energy which cannot be disproven therefore are bad hypothesis to begin with. Consider a water bed. Forces acting on it may ripple about but nothing causes it co contract onto itself. That comes closer to a description of the universe than one that is finite and collapsible. Rupert, Christian theology and its ideas of Trinity are fine, but don't forget that Christians have long insisted that God remains outside his creation, and are responsible in no small way for the reductionist approach taken by the Enlightenment science of the Industrial Revolution. But I appreciate the idea of trying to re-define a Trinity that is at once a spiritual, qualitative description as it is a quantitative scientific description. I do see that this "instantaneous gravity" idea is consonant with the idea of a "high pressure aether" so I think this is a viable alternative to seeing gravity as God's love. Wouldn't the push gravity idea be consistent with the near instantaneous gravity idea?

It has been said that gravity is not a force, but a consequence of the distortion of the space-time continuum by a body of mass. So, when Rupert is talking about the “speed of gravity,” what specifically is he talking about here? Is it the speed of movement of a distortion in the space-time continuum, or is it something else? I would also be interested to hear what it is about mass that enables it to distort the space-time continuum?

@flmartin4562 7 дней назад

The recent detection of gravitational waves from the merger of two black holes, coinciding with the optical observations of the same event, provides compelling evidence for gravitational waves traveling at the speed of light [16]. This event occurred approximately 1.3 billion light-years away, meaning that both the gravitational waves and the electromagnetic radiation (light) traveled for 1.3 billion years before reaching Earth. The fact that they arrived simultaneously, within the measurement uncertainties, strongly suggests that gravitational waves and light propagate at the same speed. Furthermore, in the field of orbital mechanics, astronomers and physicists routinely account for the finite speed of light when modeling the motion of celestial bodies [17]. This adjustment, known as the Rømer delay, is necessary to accurately predict the positions of planets, moons, and other celestial objects, as their observed positions are affected by the time it takes for light to reach Earth. The need for this adjustment implies that gravitational effects, which govern the motion of these bodies, also propagate at the speed of light.

Gravity as giving and being the great attractor causing things to meet in the midsts is a great way to place it. Plotinus following plato as you noted the living cosmos(world soul or all soul) states that "pure love is the spirit which walks with every being" he also speaks of matter in a tending unitive and energtic way calling it semi real. Even David Hume says "hyle(energy/matter) is ultimately God" .I think the trinity analogy is intriguing as well. I had never heard the story about windmill before so thank you for sharing it.

@JosephLMcCord 10 дней назад

Well - it's still spoken of as being a force (although the phrase, "fundamental interactions" is now preferred over "fundamental forces"). It's a little uncertain in fact - since many physicists think that gravitons likely exist. No quantum theory of gravity yet exists - it's more of a holy grail than an existing thing. But if one ever were successful, it might make gravity look a bit more like the other fundamental forces - again. Presumably, the gravitons would have to cause the space-time curvature. No physicists really understand this, yet.

For "warp time" analysis Maxwell's 4 equations are limiting, due toMaxwell's equations exclude "scalar physics" (however are correct for normal use), but when the original 20 equations were reduced (by Oliver Heaviside) to Maxwell's 4 equations, we lost the "scalar potential" so when the medium of "space-time" is "stretched" to its limit - that is where only 4 equations reach their limit. I suggest you take another look at "The "Universal Force" equations "Derived From a More Perfect Union of the Axiomatic and Empirical Scientific Method" (using all the original 20 physical equations) by Dr Charles W.(Bill) Lucas, Jr. in his Vol.1 of the above named publication, which incidently derives all forces - including gravity - in one equation...

The wikipedia entry on the speed of gravity en.wikipedia.org/wiki/Speed_of_gravity says that the speed of gravity is the speed of light in the vacuum. Since gravity in General Relativity cannot violate the theoretical premice that the speed of light in the vacuum is maximum speed of any physical interaction ; nothing in General Relativity can violate what is the foundation of the theory since it would make the theory self-contradicting. None of this means that General Relativity is true and that into another theory the speed of light is not the maximum speed of a physical interaction.

Tom Van Flandern was rebutted in 1999 by Steven Carlip in a response entitled “Aberration and the speed of gravity.” It is curious that the force of gravity points to the instantaneous position of the attracting body, not the older position delayed by the speed of light (electromagnetic charges work the same way). In GR, a component of the calculation is related to the velocity of the attracting body, hence the force is able to point to the instantaneous position of the attracting body. One way to interpret this may be that the gravitational field itself has a velocity (this interpretation is just my opinion, not what Carlip said).

@Tordvergar 11 дней назад

Thank you for citing that. I read Van Flandern's paper over 20 years ago, after my physicist father recommended it to me. I find most of the paper compelling, except for his thoughts on the ether. I corresponded briefly with him about that, but am not satisfied with the response. Some of Van Flandern's speculations since then are pretty extreme, in my view. Also, though I accepted the argument that the speed of gravity is >> c, Van Flandern also posited that gravitational waves would propagate at c, which seems to have been experimentally verified by LIGO since then. For my part, I can't square a speed of gravity >> c, with the speed of gravitational waves being limited to c. I'll read Carlip's paper now!

@timjohnson3913 11 дней назад

@@Tordvergar Here is an applicable quote from pg 1 of the paper: “It is well known that if a charged source moves at a constant velocity, the electric field experienced by a test particle points toward the source’s “instantaneous” position rather than its retarded position. Lorentz invariance demands that this be the case, since one may just as well think of the charge as being at rest while the test particle moves. This effect does not mean that the electric field propagates instantaneously; rather, the field of a moving charge has a velocity-dependent component that cancels the effect of propagation delay to first order.”

@@timjohnson3913 That statement didn't help me a lot because the sun and planets are all in accelerated motion, so their steady-state "expected" position won't be along a trajectory. But the rest of Carlip's paper clarifies this, and in fact he agrees with Van Flandern that higher order terms have to be accounted for. Van Flandern's paper is more accessible, much more actually, unless you've got an advanced degree in mathematics or physics! To me the most compelling parts were that there is no disconnect between the speed of gravity and the speed of gravitational waves. and that the energy carried off in the waves is on the order of v^5 / c^5. That is very testable relative to neutron star pair orbital decay, and Carlip says that matches well with observation. It would be fun to have a philosophical discussion about Noether's theorem relative to what Carlip is arguing. On that point there is a bit of danger of circular reasoning, it seems to me at first blush. Anyway, a big Thank You for citing that paper!!

@@Tordvergar Yeah if you are trying to work through the specific math of the effect of gravity on the Earth, there are a lot of things that complicate the situation (e.g. the other planets). But if you are conceptually wondering whether the speed of gravity is c or >>c, then I think Carlip shows how the mainstream view that gravity travels at c makes sense, which counters Van Flandern’s view that gravity must travel >>c.

Fascinating. We do know that shortest duration in gravity is the cycloid arc, shortest duration being relative to the radius of the associated circle. The shortest duration is also the same duration for all positions on the cycloid arc. Thus we can conjecture that gravity is cosmic cycloidic temporal pressure rolling being towards circles and ball shapes.

One way speed of gravity could travel faster than light. Two way speed of gravity is still limited by speed of light since gravitational waves travel at the speed of light. Therefore gravity could propagate faster than light but any two way interaction with gravity would still be limited by speed of light.

what has been forgotten here is that gravity is just a description of the curvature of spacetime. changes in that spacetime occur at the speed of light. if the Sun suddenly disappeared (think of the ball on a sheet analogy) it would take 8 minutes for the effect to make it to the Earth. there is no need for anything instantaneous because gravity is an emergent force.

@risingphoenix8056 28 дней назад

I think you missed the point a bit. The aberration of the sun's apparent position is exactly the issue: there is no aberration. But I do agree that gravity is "emergent", it arises as I argue, and Glenn Borchardt elucidates, from an aetheric pressure on baryonic matter. It does seem like scientific jargon has adopted the word "emergent" which I find somewhat annoying, coming as it does from people with a mechanistic materialist position.

This 8 minute delay argument can be dismissed by a simple thought experiment. Consider two masses held at two ends of a stick. The two masses attract each other by gravity. Now consider the masses to be moving in a direction perpendicular to the stick. The gravitational force will travel from one mass to the other at a slight angle to the stick, and will thus have a component of force opposite to the direction of motion. So the masses will begin to decelerate. Seen from the frame of reference of the massed, however, no such acceleration occurs. Contradiction.

Not sure where these people Sheldrake et al are coming from citing a paper that has already been explained (properly) without making ludicrous claims about the speed of gravity - see ‘The speed of Gravity Revisited’ Michael Bison, Michael & Puthoff, Harold & Little, Scott. (1999). The speed of gravity revisited. Recently Van Flandern concluded from astrophysical data that gravity propagates faster than light. We demonstrate that the data can be explained by current theory that does not permit superluminal speeds. We explain the origin of apparently instantaneous connections, first within EM, and then within strong-field GR. Conclusion ‭ ‬Van Flandern is correct in his observation that gravitational attraction is directed towards the instantaneous (unretarded) position of a moving body. We have shown that this fact can be explained without a revision of physics to include superluminal propagation. Not much effort here to present balanced view!!
