What is Dark Energy? Inside our accelerating, expanding Universe
FEB 05, 2024. Chelsea Gohd.
What Exactly is Dark Energy?
Right now, dark energy is just the name that astronomers gave to the mysterious "something"
that is causing the universe to expand at an accelerated rate.
Dark energy has been described by some as having the effect of a negative pressure
that is pushing space outward. However, we don't know if dark energy has the effect
of any type of force at all. There are many ideas floating around about what dark energy
could possibly be. Here are four leading explanations for dark energy.
Keep in mind that it's possible it's something else entirely.
Vacuum Energy:
Some scientists think that dark energy is a fundamental, ever-present background energy
in space known as vacuum energy, which could be equal to the cosmological constant,
a mathematical term in the equations of Einstein's theory of general relativity.
Originally, the constant existed to counterbalance gravity, resulting in a static universe.
But when Hubble confirmed that the universe was actually expanding,
Einstein removed the constant, calling it “my biggest blunder,” according to physicist George Gamow.

Can you give some examples of dark energy?

Now Chelsea, do you really work for NASA? Be honest. And try to crystallise your thoughts into a coherent question. Intellectually, you're all over the place.

The 5th dimension was explained by the Kaluza–Klein theory.
The 6th dimension and other spatial dimensions are belong to "string theories"

October 25, 2024. After Decades of Searching, Are Physicists Closing In on Dark Matter?
With no conclusive laboratory results, researchers are turning to other methods to find the elusive substance
/Dan Falk/
------.
.... physicists and astronomers believe that visible matter is just the tip of the iceberg, so to speak,
and that some kind of unseen dark matter must be out there as well, accounting for some 85 percent
of the mass of the universe. No one knows what dark matter is made of, but scientists are confident
it’s something that doesn’t interact with electromagnetic radiation, such as light—or else we’d be able to see it.
But decades of searching have failed to yield any direct detections of this dark matter,
leaving researchers wondering if they need to broaden their search strategies,
or perhaps even rethink how gravity works.

The case for the existence of dark matter goes back to the 1930s, when astronomers analyzed
the rates at which galaxies rotate and found there isn’t enough visible matter to account
for the observed spin-rates. These so-called rotation curves, which plot the speed at which stars
are moving as a function of their distance from a galaxy’s center, couldn’t be accounted for based
on the amount of stars, gas and dust that’s visible within each galaxy.

We don't need a lab, we need a brain. Matter is "implanted" into structure of physical space (aether), it is actually a damaged, deformed physical space, elementary particles are basically defects in the regular structure of physical space, and the massive movement of stars in galaxies is actually the overall movement of physical space (aether), pulled by "ingrown" matter...

In fact, it is similar to the wave-particle behavior of elementary particles. For example, when an electron passes through a (double) slit, the surrounding structure of space (aether) is dragged with it… Apparently a "dark" electron

What would you consider to constitute 'direct detection'? I mean, have we directly detected baryonic matter yet? This all seems to just be a quibble about where we draw the direct/indirect line. We see dark matter affecting stuff. That's as much a detection as the brick hitting your head. Not sure if the brick was considered to be indirect or not.

I think the researchers want to isolate a piece of it, put it in a box so to speak, run tests and such. Verify that indeed, the bit of dark matter is indeed within this small bound we define as 'a box'.

What has this turn have anything to do with the thread title? It's dark, so it's relevant? Dark chocolate opinions are welcome?
Just asking...

Well, we see an effect. With regard to baryonic matter, we can attribute measurable qualities to reasonably defined coordinates on a very small scale. In essence, that is how we define particles. We haven't discovered any such small scale measurable qualities that could account for the effect attributed to dark matter.

That's the nature of ambition. Anyone who manages to do that will be heading to Stockholm.

It is a rule of PN that a thread adheres to its title for a maximum of 4 posts. My own view is that big bang stuff/the inflaton, call it what you will, is still expanding/inflating. Gravity is a localised effect caused by refraction which at intergalactic scales is overcome by expansion/inflation. Dark matter is analogous to the heliosheath and dark chocolate is a glass of milk away from being edible.

1- boson passive particles (have an integer value: 0, 1, 2, ...)
2- fermion active particles (have half-integral value: 1/2, 3/2, 5/2 ...)
3- gravity is a localized effect caused by boson matter + fermion energy

Hang on, that's in the context of The Ealing Interpretation. No idea whether it's actually true.

Well, at least one of us is wrong.

ONCE AGAIN, objects, of 'matter', which is what so-called 'big bang stuff' REALLY IS, are seen to be expanding away from each other.

your own view is not a very insightful view.

Also, your view is just a very narrowed and a very short-sighted view, only, of all-there-is.

'Dark matter' and 'dark energy' are more or less just words synonymous with words like 'God'.

When some human beings do not really know what they are talking about they quite frequently make up words, in the hope that they will sound like they know what they are talking about. Usually done by those who like to believe that they are the so-called 'experts' in a subject, like, for example, "priests/preachers" or "scientists/astronomers". All of these people are AS BLIND and AS CLOSED OFF to the ACTUAL Truth, for the EXACT SAME REASON.
