Is Our Model of Dark Energy WRONG? | New 4.2σ Results

Engagement text

I’m sure you get tons of people asking or proposing similar things. And I’m sure you are tired of it. But I’m going to add one to the pile.

What were to happen if there were say, an upper limit to a black hole, if there were a point where it could not remain a singularity.

We know that matter under pressure accumulates heat. Black holes have a singularity under mind boggling pressure at all time, and they remain that way for essentially forever. That heat cannot escape in any meaningful manner, the only way it has to escape is hawking radiation.

Say this black hole nearing its “limit” and let’s set this towards a mostly heat dead universe, where the only things still interacting are black holes.

Now let’s place three gravitationally relevant black holes, two of which are actively interacting with each other producing gravitational waves. While the third one is far enough away to not gravitationally interact in any meaningful manner.

Could the black hole pair produce gravitational waves, that interfere with the “vent” of hawking radiation, preventing the escape, and instead causing the mechanism behind hawking radiation, to rather feed the black hole.

And over enormous time spans take this black hole to the limit where it cannot sustain its singularity.

What would that look like? Would that be possible? Assuming there is in fact an upper limit to how large the singularity can get, would the sudden inversion of space time curvature create conditions similar to that of our big bang?

Yes it is fading at approximately 0.64% per GYR. I have seen the face of God!

Also there is no singularity in a black hole.

Remember this comment

How long has this been going on? Why did we not notice until now?

I wonder why HETDEX was not mentioned?

No sh!t

could "dark Energy" be space itself? i.e. space can be compressed and space can be stretched. So if space has a "normal state" and from the big bang space has been trying to get back to its normal state. and that is why expansion is slowing down because more and more space is getting to it's stable state.

*EDT

"Dark Matter" is simply an error in our model of the universe. Our model, while internally consistent, fails to accurately predict how galaxies hold together, but rather than reexamining our model we cling to it and invent a magical substance which cannot be tested for, cannot therefore be disproven, which makes it a religion and not science.

TLDR: Matt-O on dark energy: Yah, nah mate

Great episode

It is incredible how much effort ppl can do to keep a wrong hypothesis afloat.

Imaginary energy

All of the missing dark matter. It's probably just behind the event horizon of all the black holes. The way we measure their mass with gravitational lensing does not take into account the fact that we don't know what happens beyond the event horizon.

Why shut down DESI after the third data release?

You guys still believe in space? Typical

Clear, factual and always fascinating. Thx !

I think some breakthroughs in the study of dock energy to come would be the effect on fishing catches and shipping volume. It probably pays to start the journey with a positive mental outlook.

Matter absorbs space-time, which is why masses attract each other and bodies "fall" gravitationally. Matter absorbs the energy of space-time and transforms it into potential energy, that is, into massive accumulations of matter. Free energy generates space-time, which is why photons stretch and lose energy. They actually transmit their energy to space-time, which transforms it into kinetic energy, pushing galaxies away from each other ever more rapidly. Therefore, the speed at which space-time expands in a region depends on the amount of matter and the amount of energy within that region. In the Big Bang, there was much more free energy, which is why space-time expanded much faster, but over time, there began to be more and more matter, which is why space-time now expands more slowly.

One of these days some science university is going to be accidentally bullied into shutting down their Dark Energy Initiative program.

I don't believe in anything anymore, because in 10 years they tell us something completely different. Again.

Is that the reason, why dark energy is needed? Because they measured acceleration of expansion???

Well, Couldn‘t it be explained this way instead:
The closervan object comes to a black hole, the slower the speed of time elapses. In the opposite that means, the further an object travels into lower density space (outer space regions) the faster the time runs.

This means we observe objects travel into faster timed places, making them appear accelerating.

For that explaination no dark energy nor dark matter is needed.

right?

Scientists are very similar to politicians and lawers.... overpaid mostly useless and knowingly lie with every breath

In Fermilab’s halls, where particles play,
On April 7, 2021, a new day.
The Muon g-2 Experiment took the stage,
With findings that might rewrite the age.

A 4.2σ discrepancy, they found,
In the muon's magnetic moment, profound.
Aμ(Exp) = 16592061(41) × 10−11,
Combined with Brookhaven’s data, so clear.

The difference, (251 ± 59) × 10−11,
Points to a world beyond the standard model’s discipline.
3.3 standard deviations, a hint so bright,
Of new physics that could soon take flight.

So remember, in the realm of the small,
Where muons dance and mysteries enthrall,
A 4.2σ result may guide us yet,

June being the black hole month... Nasty!

These kind of videos give the feeling that we are truly living the advancement of science and knowledge in our short daily life. I'm used to learning what was done, but it is so rare to experience this (at least for a non-searcher like me). Thank you.

I wonder if it is possible that both expansion and contraction are happening at the same time in different parts of the universe. Perhaps black holes have a critical mass and eventually explode producing a localised expansion, which eventually will run out of momentum and start to contract again.

Big cr😢nch

Well U of C now says new JWST data ends the Hubble Tension. So I don't know what to believe anymore.

To be fair to scientists, we try to understand things that are way beyond what we where made to understand! The fact that we even know about the expansion of the universe and all this other incredible information which is present at scales which we can't conceptualize in our brains, is extremely impressive to begin with.

You got your Merch guys working on the new Tool album cover.

give dubbing option

Can someone please explain how we are detecting photons through space to measure distances whilst knowing that the detection of photons itself collapses the(ir) wave function & how that does not affect the accuracy of the distance measurements which underpins the current understanding of cosmology?

Humans just can’t help but be mapmakers at the end of the day.

Thanks for another awesome video. Still one of my top favorite science channels. Keep up the good work!

When will we be talking about the accelerating expansion of the merch store

DESI hints at large scale 'local' attraction in the BAO-generated matter clusters, slowing expansion - and even reversing it. Conversely, the voids, potentially rich in anti-matter/dark matter, do the reverse. Suggests to me two flows of time in the same universe, the anti-matter being of a form that tends to temporally run away from normal matter interactions. You then have two sources of external input at every point of spacetime: For matter, there is the CMB persistent perturbation stream. From the future, you have a big crunch; track that back and you have a persistent stream of disallowed future possibilities. Interestingly, should neutrinos be Majorana particles then the CNB could come from either side? Anyway, there are asymmetries between matter and anti-matter (eg muon decay chirality) so the start of the universe and the crunch will not be identical mirrors. This leads immediately to recognising, in a temporal flow/counter-flow universe, a big bang followed by a big crunch would involve a double tap for the matter and anti-matter bounces. At the very least this offers an alternative model to supra-luminary early inflation. Note, I can find no other reference to a double-tap big bang, suggesting this is a new idea. Just thought I would share it.

(1-√3π/16)/πc^2 😂

Yes because the speed of light is not constant. It’s infinite. We only observe and measure it at the specific speed because of the gravity well of the Milky Way, solar system etc. we have only measured the speed of light from earth.

P.S.- there’s a reason photons experiences no time 😏

This channel is running out of content; 21 minutes of Blah, Blah, Blah, oh and by the way so far this isn't even a real and proven result.

21 minutes of nothing very much that I'll never get back again.

4.2! Almost there!

Why announce time in EST? Surely UTC makes more sense.

From One came many, and many will come together to be One. One for all and all for One.

Mithuna nice

lsst, definitely not ludicrously sized survey telescope

And what if David Wiltshire’s Timescape Cosmology is right? I think he expects the Euclid satellite data to tell us. That will mean Einstein was right that lambda = 0. I wish you and other physics podcasters would start saying “apparent acceleration” until the bizarre idea of anti-gravity called dark energy is on more solid ground (if it ever will be).

If we do a modelabout something which doesn‘t exist, it‘s probably wrong.😂
