Cosmic voids may explain the universe's acceleration without dark energy

[Admin]

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.

If we apply relativistic addition of velocities to the cosmic expansion,
V(r)=Hr becomes V(r) = c * tanh(Hr/c).
This explains the illusion of cosmic acceleration without assuming dark energy.

I don't see any reason to assume the cosmic expansion is Newtonian.

Is it just me, or does it appear there is a desperate search for some kind of cause to explain what they think they see? Our science is convinced that space and the matter in it is expanding, or has expanded at great rate, to form our present universe.

It seems to me that when you measure a symmetry referenced on your location, Such as velocity spheres in proportion with 360X360 distance, that one or both of the theses possibilities are occurring.

Possibility 1. There is an error in our measurement. A proportional error with the dynamic of the measurement. An unknown coefficient. Or perhaps the measurement itself is adding something to the measurement. Some sort of a rate distortion. Perhaps a rate reactance. A common physical property. Light has the highest rates we work with. Wave period rates.

Possibility 2. A false understanding of the what we are measuring. For instance the velocity of light has never been verified. And when measured the value has always been different. They believe one way speed is impossible to measure. With decades of CERN and all these telescopes and we can’t measure light. So the assumption continues.

But will spend years looking for that force that is blowing our space bubble.

There is no way to determine when, where or how this “bubble” started. And I seriously doubt it’s a bubble.

I think space itself is just an empty cube that has no end. With intermittent EM fields flying thru it. Only the time, the distance between the EM field, changes with motion.

It’s a duty cycle universe. Light is the rate of presence and non presence. And in a flux, a portion will always be present. Forming a continuous stream. With the other portion being always absent.

Light is only there for half of the time.

If the photons of a star were phased, stars would blink.

This is sorta what I was pondering. The idea that voids are expanding faster, and thereby show more acceleration for SN that we observe in their direction would make sense if it weren't isotropic. Why wouldn't we see varying acceleration rate proportional to the voids in any one direction?

Also, if voids are expanding, then what do we call the energy causing their expansion. Isn't it DE? So how can voids explain away something it must have in the first place?

I know, it just adds another paradox to this cluster.

I suppose we could write a library about why science has problems with the question "Why?". So not doing that here.

What if the cosmic expansion just is, and doesn't have a "why"? Like explaining why the speed of light is a universal constant. What if the expansion is a property of the universe, and has no cause, but just is? If so, then there's no reason to look for a dark energy.

Natural forces keep small structures together, but get weaker with distance. Smaller structures hang together because the known forces convert the increase in potential energy into the kinetic energy required to keep the structure together. Increasing distances weaken the natural forces, but have no effect on the expansion. So distant galaxy clusters fly apart from each other, but the stars in a single galaxy do not.

What if our meter sticks are not expanding with the cosmos, but our multi-megaparsec sticks are expanding?

The thread " It's all in plain sight, maybe" is a good argument developed from the thread's contributions.

As in the Timescape Hypothesis, the principle that time runs faster in voids (away from mass) is used but extended thus:

• If the mass density of space is reduced time runs faster
• If the universe expands the mass density of the universe's space is reduced
• Expansion causes time to run faster as space mass density is diluted
• Time runs faster causing expansion to increase faster which causes a loop effect called acceleration.

The above is simple and straightforward. More difficult is:
Unfortunately, the mathematics is skewed by the insistence (dogma science fiction) that time runs with parallel arrows from all locations even though it can be shown that time dilation is simply a rotation of direction in all circumstances. The rotation of time in gravity wells explains why the voids of the universe have not expanded so fast as to make all mass connecting galaxies into blackhole valleys of almost infinite depth back to the BB.

Hmm, never thought of that before; what if all black holes simply take mass back to the BB in a sort of time collapse where the mass is so great it bores a hole back to the BB singularity? Might be worth exploring a bit more as a sort of time loop recycling. If you don't like thinking (as best we can) in 4 spatial dimensions this will not make any sense
