Image: Getty Gravity, relativity, space and time — Albert Einstein explained all these and more. But he had an uneasy relationship with quantum theory, and with physicists still casting around for a unifying theory of physics, his ideas in all areas are under scrutiny like never before. Why Einstein was wrong about relativity The special theory of relativity is one of the most successful theories of modern physics — but one of its assumptions is way off-beam. Gravity: Were Newton and Einstein wrong?

Astrophile: Trio of dead stars could take on Einstein The first example of a three-star system containing only stellar corpses could be used to probe the nature of gravity. Why space and time have a secret connection If we want to progress towards a theory of everything, we need to understand how space and time fit together — if they do at all Watch on YouTube.

New kind of light is a vortex beam that twists faster as it moves A laser beam can be twisted and move like a vortex, and for the first Mars meteorite assault stopped million years earlier than thought The Late Heavy Bombardment may have stopped on Mars 4. So although things like energy and matter were quantized during that shift to quantum mechanics, space and time remained continuous. In general relativity, space and time emerge as a kind of dynamic variable of the theory — it should not be assumed as a background.
Rather, it demonstrates that gravity is not a force, it is the result of the curvature of spacetime caused by the presence of mass. The idea was to try and find a way to make spacetime emergent in the field of quantum gravity. UD: What does quantum gravity tell us about the existence of time, or the nonexistence of time?
One Universe at a Time
JB: The great physicist Paul Dirac found fairly early on that you kind of lose track of time in quantum mechanics. Time gets lost in the equations, so you have to bring it back. It has to be reinstated, in effect, as a juxtaposition of different spatial states, i. So, as the geometry changes, it creates the impression, or illusion, of time. Talk to co-founder of the LQG theory, Carlo Rovelli, and he will tell you that time as we perceive it is an illusion, and that when you get down to the Planck scale, time ceases to exist at all. But is this something that truly reflects the real nature of time?
Honestly, who knows?

UD: Where do you think the theory is moving now? Can observations and experimentation help to prove it? JB: This is a really difficult area. This brings us into the field of loop quantum cosmology, which is a large-scale picture of the universe based on LQG. Loop quantum cosmology suggests that we may have had a Big Bounce — the universe collapsed in on itself at one stage and bounced back out — rather than a Big Bang where the universe exploded from nothing.

What is the fire that informs the equations, that brings them to life? So how do laymen, and even those in official science, keep a sense of balance? Maybe it is a matter of attitude. We can be humbled before the Mystery,but still enjoy what knowledge we have. How does gravity work at the particle level?
Buddha and Christ or for that matter any religious leader probably did not know of the Higgs boson or gravitational waves unless the ancients had some alien visitors with superor intelligence imparting or are still imparting superior knowledge to our feeble minds in ways and technologies unknown yet to us. The general theory of relativity and quantum mechanics are working models in their realms and we should strive to understand the whole, only a part of which, our evolved senses can perceive.
Science by way of mainly mathematics is trying to transcend those very limitations IMHO. Excellent thought process. Or maybe mass making an impression in time that we perceive to be gravity. It could also explain how and why our universe bends and expands. Space is only 3 dimensions. Why do we have to add to it?
LQG has been around for, what, years? But … a…. Time is an entangled byproduct of what is really going on, down there, at the quantum level. Causality is the propagation speed of information and massless particles. Those interactions cannot be pinned down with a frame of reference, therefore time itself is not the same as sheer existence. In my mind time is not a dimension, so much as it is a handy tool for adding dimensionality to that existing thing. The information interactions are what present the illusion of a forward arrow of time, as they become entangled and change the outcome of different interactions based on their other partner, they sort of create a chain reaction effect.
Whatever entanglement really is, and whatever causes there to be a causality speed limit are the important factors. Since wrapping the human mind around things smaller than what we are made of, ie matter, it is quite understandable that it makes no sense.
I feel like the Higgs mechanism that gives some interactions mass is kind of the same type of phenomenon. I look at it sort of like Schrodinger looked at velocity and position for particles. But, I ask if that is because there is something fundamentally funny happening down there or because we can never use mass, or particles for that matter, to measure that small.
Sometimes location, sometimes spin, but change they do. But they are just the ripples, for lack of a better word, emanating from whatever quantum energy space is. Which is where Schrodinger comes into play. This infinitely fast oscillation of this Planck volume is emanating information faster than we can comprehend. Time means nothing in the ever present now of infinity. In that case, the three spatial dimensions would actually be byproducts as well.
The only two things I can think of are that existing thing and entanglement or one of the two is a product of the other. One dimensional, hope all of this helped. What are those vibrations? Why do some see the golden ratio in some of their findings? Could the impression of said matter on the 4th dimensions be the cause of these vibrations? Too small to be felt and seen but everything when it comes to the makeup of the universe? Strangely enough, none of this is new to us. I would love to read more of your opinions though including more of your observations. I think we need to delve into this question: How much of the universe, perceived by our senses, is a byproduct of our senses themselves?
I do believe the biggest mistake modern cosmology makes, is the assumption that we exist separate from an external world. Excellent article. Interesting theory on how time does not exist at this below subatomic scale. Why is this I wonder? More research funding is needed for these fundamental questions!

Can we approach the puzzle of reality the meditation way, the way the Buddha taught? In physical world, it is improbable to synchronise Planck and cosmic scales, yet in the arena of consciousness, both the scales are found in sync perfectly. However large the LHC may be, it may not be the universe-sized and that is when and where reality lies and that can be attained only by way of meditation, i. If you read over ancient texts, dimensions of life and consciousness might just be different intensities of energy and different levels of molecular structures. We just translate the language of the universe.
And the impression of time is exactly that. Impression in time because time is as real if not more so than space itself. Different but intertwined. It expands. Imagine time as water filling up an aquarium. And read over pythagoras, newton, einstein, and all the ancient scripts all over again. Try and see how gravity would work in that model.

In the beginning God created the Heavens and the Earth. Our finite minds are capable of much understanding but are as nothing compared with Almighty God, who not only created everything but sustains it by his Word the Lord Jesus Christ. All religions put together are not going to shed one iota of light or any detailed knowledge on theoretical physics.
They never have and never will. Neither Christ nor Buddha nor any other major figure of the past from religion has done this. However, if we were to take all the military budgets and monies earmarked to maintain religions for just one year, we might be able to build a decent next generation accelerator. It would provide a lot of jobs, shared purpose and a worthwhile set of goals to strive towards for humanity — as opposed to all the petty disagreements about whose religion or political ideology is right.
Read Freud. All the mathematicians the world had ever produced. Beyond their math, lies the truth in their words. Or better yet. Go stand in front of a hurricane and try to flip dice or pay for your existence. But one perfect algorithm to make all our reality possible. But i forgot. That might be on its billionth cycle. How exactly do we have shared goals and values about what things are worth or not worth without religious, philosophical argument?
