Editor's Choice: The Illusion of the Expanding Universe

Sorry, forgot to mention also that the gravitationally induced expansion of spatial volume has been observationally confirmed recently by the Cassini space probe!

Cheers

I do not agree with dividing energy in positive and negative.

Energy simply is.

Sum of energy of space (gravitational) and mass is not zero, it is constant.

yours amrit

Amrit,

Roy isn't saying there is no energy/zero, but that the positive energy of radiation and the negative energy of gravitational fields balances out.

Roy,

"Just thought, could the apparent cosmic expansion simply be due to a global expansion of space being caused by the *global* distribution of matter fields in the same way? On cosmic scales this may cause an expansion of space on the geometric hypersurface (as observed) and could still co-exist with a globally "flat" geometry? Mmmm...not sure though if this would be observable from within the Universe??"

Keep in mind that the only distant light we can observe is what has traveled through the least dense space.

I don't think of space as a consequence of energy. In fact, I'm inclined to think of energy as a consequence of space. The vacuum isn't due to the fluctuation. The vacuum is the equilibrium state of the fluctuation. Science likes to think only what can be measured exists and that space is created by measurement. The wouldn't explain why something spinning in an otherwise completely empty void would still have centrifugal force, or why the speed of light is constant, irrespective of the velocity of its source. Space is the equilibrium state around which these positive and negative fields fluctuate.

Say we have a small celestial body spinning in fairly empty section of space. We know it's spinning because the distant stars are in celestial motion, but also because there is a centrifugal force, like is used to sling shot satellites off planetary orbits. This effect isn't due to the fact there are other stars out there, but because that body is spinning relative to some equilibrium state.

John energy is energy, energy is not positive and not negative.

Quantization of the cosmic space allows introduction of density of cosmic space. Medium that has granular structure can also have density. More mass is in a given volume of quantum space, less space is dense. In General Theory of Relativity gravity is generated by change of curvature of cosmic space, here by change of density. The basis for curvature of space is its density. Einstein curvature tensor G in a form 1/G is Density tensor of quantum space.

Idea here is that quantum space has its density. More mass is present in a given volume of quantum space, less space is dense and more space is curved. In quantum space physical time is run of clocks; time is not part of space, quantum space itself is timeless.

Einstein curvature tensor G is in relation with Density tensor D of quantum space by equation:D = 1/G wich becomes in geometrized units D= 1/8piT

Curvature of space has it physical basis in its density. Change of curvature of quantum space corresponds to the change of density of quantum space that generates gravitational force. With introduction of density of quantum space "action on distance" is resolved. Dynamics between mass and density of space generates gravity motion.

amrit,

Let me put it this way; If space is curved inward, it is contracting and becoming more dense. If space is curved outward, it is expanding and becoming less dense. If space is doing neither, it is flat and in equilibrium.

Density tensor D of quantum pace is D=1/G where G is Einstein curvature tensor wich becomes in geometrized units D= 1/8piT

Amrit,

There is some level of energy in space, be it simply "fluctuation." Some areas the density of that energy is decreasing and some it's increasing. Why? Say some is positive and some is negative. They attract. That creates greater density. At some point this process breaks down and the energy gets radiated back out and the space defined by that energy is expanding.

The Big Bang theory seems based on the assumption that all this energy can coalesce to a point and expand from there. It seems more logical, from a physics perspective, that the default state would be a high entropy, even distribution of energy. What seems to be the motivation factor to prevent it is this equilibrium isn't stable. Even if evenly distributed, areas will still tend to collapse, creating less density around them and a build up of high energy, low entropy within them. Thus an infinite process.

Even the Big Bang theory implies this progression, as the entire universe implodes and explodes, but it tries to deny the equilibrium state of space and has to add various fudges, from inflation to dark energy to make it work.

Yes, John energy flow matter-quantum space-matter in the universe is in dynamic equilibrium.

I do not see right saying positive or negative energy. This idea if from Dr. Hawking. Energy of mass is positive and energy of gravity is negative, sum is always zero. For me sum of energy is constant and not zero.

yours amrit

amrit,

"For me sum of energy is constant and not zero."

Meaning it can never be in perfect equilibrium. There is always motion.

John yes, mass transforms in quantum space and quantum space transforms in mass

Although in physical systems, which are always bound by some gravitational or electromagnetic field, there must always be "motion" because you cannot find yourself in truly empty space, at least at this "point" beyond the Big Bang.

But 40 years with computers has bent my feeling about time into discrete pieces, which are quite important to the synchronicity of information. Without time to break into little pieces, the state of a system would just be a jumble of gray goo.

Also, my own memory seems to be indexed by time, I don't remember "where" without also remembering "when". So, whether physical reality manifests in time and space or not, our psychological systems cannot function without those concepts. Whether in physical or mental reality "space time" must exist.

Space-time is an inner map of the mind into which we experience change in timeless space. We measure this change with clocks. Clocks run in space only and not in time. Run of clocks itself is time.

yours amrit

This article should have started:

"For someone who believes time doesn't exist, Julian Barbour sure is old."

Our definition of time cannot be based on belief. On the base of elementary perception we can conclude that physical time is run of clocks in quantum space.

Time exists as a man created physical reality with which we measure material change. Change run in timeless quantum space. Universe is timeless phenomena. Einstein and Godel knew that. Now is on the scientific community to recognize space-time as a math model merely and timeless quantum space as a fundamental physical reality where time is run of clocks.

A cone would be better than a triangle. Time is relative to what one is doing, i.e. sleeping for 8 hrs can seem like it was a couple of minutes, and if one takes schroenengers Cat experiment then nothing exists in space or time until it is observed, so there fore everything in the universe disapears until it is observed or acknowledged by ones own consciousness i.e. mine, so when i die everything disapears and entropy is restored.A somewhat narsosistic approach but fits really well into everyday life.

Hi Craig

Schrödinger cat in box is an interesting question. Cat remains in a box one hour. When atom decay happens cat is dead, until atom decay do not happen cat is alive.

Cat is alive or dead before we open the box. It is not that with opening box cat will be alive or dead. Opening of the box has no relation to cat life.

If cat is alive when we open the box decay of atom did not happen in one hour, if cat is dead we can do autopsy of the cat and calculate when atom has decayed.

Cat biochemical reactions are natural clock "tick". With autopsy we can see when (if) cat as biochemical clock has stopped.

Cat experiment is independent of the observer. Atom may decay or not.

Might be observer love for cat helps that decay of the atom do not happen.
