QuantumT

So, is it basically a search for gravity?

I have attempted a few conjectures the latter years, and been proven wrong. But still I can't help myself trying again. Is that good or bad?

About gravity, my latest conjecture is that it is not found in the standard model. It is dark matter. Gravity is dark matter.

You don't need to state the obvious: that I'm wrong.

Or they could be large scale, in which, lower dimensional 'branes' reside.

Please elaborate, or maybe link to a video (reading can become tiresome).

I have never heard that. It doesn't sound like something a physicist would say.

They are not just within particles, but the idea is that they are "rolled up" small so that we do not perceive them.

On the other hand, they could just be a mathematical model, and not actually exist.

And on the third hand, string theory might be wrong!

Thank you!

No physicist said it. It comes from fiction mainly. Just wanted to be sure it had no foundation in real science.

Some interpret the 11 dimensions of string theory as "other worlds" that could host life. I've met many spiritual people who use that as a scientific validation for the "unknown".
But as I've understood it, they are subatomic dimensions, that only exist within particles.

So which one is it? Just to get it settled once and for all...

We could put it in the drawer along with reversed entropy, parallel universes and supersymmetry

Second, Sagan's point that civilizations would exist at different intervals, divorced from one another over eons of time, assumes one thing: that all intelligent civilizations would behave like Earth's.  That is, all civilizations would rise and fall, as those on Earth do, and would eventually end in extinction within a relatively short time.  But what if this isn't the case?  What if other intelligent species establish equilibrium or harmony on their planet and can exist indefinitely, through the wise marshaling of resources and lack of egoistic competition?  Why should we assume that all intelligent civilizations behave as haphazardly and ignorantly as human civilization does?

I find that argument very unlikely. Our intelligence emerged from being predators outsmarting our prey. That drive has kept us going for millennia and can be seen in the way we compete. Without that aggressive drive, we would probably never have evolved to our current state.

So, I argue that aggression/competition is a key element in any emergence of advanced civilisation. You can't have one without the other. And thereby you can't have have a peaceful, non-aggressive, advanced civilisation.

The whole premises of this thread is based on the 2016 Asimov debate, where the conclusion, of us being simulated, ended up way below 50%. In that debate Tyson was acting as a host, and only commented on the statements made. He was being funny and tried to entertain the audience. We need people like him in science, if we want the public to engage. And we do!

According to Tyson there is no reality to measure, because what we perceive as real is simulated.

I think he watched one of those Star Trek Next Gen episodes with the Holodeck

You are so wrong it's becoming ridiculous. Don't you have any pride? If you do you should stop.

Ok, teach me that you are not real

Before we can talk about what is real, we must first agree on how reality is perceived and measured. Do you know how?

If Tyson is a brilliant educator, then you are a computer simulation that was formed in Darwin's pond.  Oh wait the pond is a simulation too so that can't be correct.  Tyson seems to be leaning to God is the simulation creator...……….

Yea brilliant

You are letting your personal feelings getting in the way of facts and learning. And in that process you wrongfully degrade good people.

As much as I like Neil he is not the last word on this and has no evidence to back that up... 

https://futurism.com/sorry-elon-physicists-say-we-definitely-arent-living-in-a-computer-simulation

The research in that link only proves that you can't simulate a quantum based universe from inside a quantum based universe.

If we are simulated, I find it likely that QM is a biproduct of it. An area they either failed to see us discover, or an easter egg for us to find.
Either way, they do not have QM. That at least we can learn from that article.

What would it take to get a visit from E.T.?

Before we can determine that, we need to know what is required for intelligent life to emerge, and get here.

- A rock planet with a magnetic core
- A large neighbor (like Jupiter) to shield against most large object impacts.
- The right distance to the star
- The right elements and circumstances for life to start
- Preferably a moon to make tides.
- The right timing to make thousands of years of space travel coincide with arriving in our time. Right now!
- Stumbling upon Earth as a one in a gazillion chance. Literally a needle in a huge stack of needles.
- After beating all the odds, being unwilling to show you presence to the general population. Playing hide and seek, despite being superior.

Radar recordings are evidence

What are you afraid of?

Evidence of what? All it shows is "something" in the air! And that something must be extraterrestrial according to you?

Conclusion without evidence is superstition. And there is zero evidence of extraterrestrial visitors.

No. He was just a radical jew, who was executed. If he existed at all.

Were you going to address my question?

Sorry for not replying. I was not notified about your message, and you were (previously) quoting the article, not my words. I'm just the messenger.

My interpretation of this, is that it confirms "the observer effect", just like the delayed choice quantum eraser experiment does. So we have two different experiments that contradict the "measurement effect". Two different experiments that shift the culprit from the instruments to the scientists themselves.

Then you probably haven't played the game to any half decent standard or competitively. ;-)

The hardest game I had was 36 holes on a links course in a near hurricane and torrential rain. Over 90% of the field withdrew throughout the day. I ached everywhere afterwards and had so little energy left in me that I had to lie down when I got home and rest (after food).  I won the net prize for playing to somewhere near my handicap - which was a nice big silver plate and a £100 voucher for the pro shop.

I knew a hairdresser like that once.

You don't have to break a sweat, and you can still call it a sport.

Might I suggest a digital science section? One that addresses reality as virtual.

Many might not like it, but it's come to stay, so why not talk about it openly?

Do you mean create more space between things; ie. push things apart?

Yes, that's what I meant.

Virtual particles have zero volume.

Although it is sad to be proven wrong I am grateful. So thank you! Now I can move on.

DE component

What is that? The energy from the big bang?

One day, Einstein has to speak at an important Science conference. On the way there, he tells his driver, who looks a bit like him:

"I'm sick of all these conferences. I always say the same things over and over!"

The driver agrees: "You're right. As your driver, I attended all of your conferences and even though I don't know anything about Science, I could give the conference in your place."

"That's a great idea!" says Einstein. "Let's switch places then!"

So they switch clothes and as soon as they arrive, the driver dressed as Einstein goes on stage and starts giving the usual speech, while the real Einstein, dressed as the car driver, attends it.

But in the crowd, there is one scientist who wants to impress everyone and thinks of a very difficult question to ask Einstein, hoping he won't be able to respond. So that scientist stands up and interrupts the conference by posing his very difficult question. The whole room goes silent, holding their breath, waiting for the response.

The driver looks at that scientist, dead in the eye, and says:

"Sir, your question is so easy to answer that I'm going to let my driver reply to it for me."

And wouldn’t creating “more vacuum” (whatever that means) slow expansion?

This is my perspective:
Spacetime has no problem with vacuum. It is just the void between matter. The more vacuum added (space between matter), the larger (or less dense) the cosmos gets.

What I don't know is, if virtual particles has volume? And if that volume is added to space when they appear. If so, my conjecture is that that tiny volume will be replaced by a tiny vacuum after the particles annihilate each other.

Moderator Note

At almost 300 posts in, you should know where “I have a conjecture” should go, and that we need a model and/or evidence - some way to test it.

 

Thanks for not shutting me down. Yes you are right. I knew where to put it, but I got carried away and hit submit prematurely, because I was confident about the details in it.

Regarding evidence, I was hoping the in-house mathematicians could clarify or dismiss it. If not, it seems logic that anything added to a volume adds to it, even if it's a vacuum.

Quantum fluctuation is the main culprit behind the big bang singularity after all, so it would only seem logic that fluctuation could also accelerate the cosmos.

Is the universe still accelerating? Sometimes I read articles that argue against it, so I'm not totally sure anymore!

But if it is, I have a conjecture that might explain it. It is based on quantum fluctuation.
(1) I might not be the first to think of it, and (2) it might be mathematical impossible, but here goes:

Quantum fluctuation is (as far as I know) considered a come-and-go phenomena. Hello, goodbye. 2 - 2 = 0. But what if it leaves a vacuum? A tiny tiny vacuum?

If so, there must be gazillions of tiny vacuums made every second. Speeding up the cosmos?

(Sorry if this is wrongly placed! Feel free to move it to Speculation if needed.)
