I expect this thread to die quickly. Who is into quantum physics

[nowisthetime]

Run silent you got more than you bargained for dude!

I must admit, quantum physics, is far from my expertise for science, but it has been enlightening reading through this thread.

Suppose the Universe is a Bell Jar and resonates at 0.03 mcSv/h, which is to say its not down here but up there now, not to burst any ones bubble the expanse is quanta, a finite measurement resulting in quantum mechanics ...

Its the thought that counts?

I like to ponder resonance and harmonic energy whilst considering perpetual motion possibilites also.

Anybody have any opinions on the computer science problem, P vs NP?

I think it's the same as the "ghost in the machine" problem.

 

[magicalmoments]

It's a totally different way to think about what you know.

With or without blindfolds?

When A belongs to the whole of B and to C and is affirmed of nothing else, and B also belongs to all C, it is necessary that A and B should be convertible: for since A is said of B and C only, and B is affirmed both of itself and of C, it is clear that B will be said of everything of which A is said, except A itself.

With and without. Schrodinger's cat.

I am so glad this thread is still alive. Einstein could not even get his head around it. Most of his theories seemed completely out there but have been proven right. And some have been proven wrong. It's all existing and exciting.

One thing about observation. If three people observe a car you will notice it. Whether it is approaching, passing by or moving away depending on where you are standing. All observations correct. From each observation a decision can be made. A car approaches,a car passes or a car moves away. A law can be made based on each observation.

This is an oversimplification of quantum theory but all things are happening at the same time. Observation changes what we see and the outcome we decide on.

Edited to add. Quantum says all things are happening at the same time.

 

[Dribble]

String theory is where its at...
I do not enjoy spending all my time on 5000+ piece jigsaws, whilst all the the time knowing there are at least several important pieces missing from each puzzle. People have dedicated their entire lives to finding the missing pieces. 42

Oh please....how does string theory predict the expansion of the universe speeding up? Dark energy is the only plausible answer. String does make interesting conversations in terms of dimensionality but there still has to be something countering the attraction of gravity.

And much of what we are now observing happened a great long time ago. Before Humans existed. Possibly before Earth existed. Think deep space.

Dark energy is a missing piece of a jigsaw and a hopeful equation, no doubt a convenient answer..
Centrifugal force, in a universe sized vortex of votices containing matter of varying sizes and densities lends itself to a certain amount of non mathematically explicable variables.
Within a controlled gravity stable enviroment(your kitchen), open a bag of m&m’s or whatever and place them in your hand.spin anround and around. Before you toss them into the air, predict their individual flight paths,trajectories,interactions and landing spots(apart from the obvious floor).
Yes..... Dark matter matters if it (must) exists.

Love it. String and quantum makes us think about everything.

This is presented just for fun.

No. You don't go back in time in your same dimension/place. You go to a different dimension/place. That dimension/place may appear to have occurred before of after where you were.

You might 'leap' to a place that appears to be your neighborhood in the 1950s, but in reality it may be another dimension that has not yet aged past the 1950s that yours has.

Think of membranes as printed wallpaper with a distinct pattern. With some care and reference points, you can match the pattern edges as long as that pattern was carefully printed so that the pattern matches exactly. If you just lay several pieces out on the floor without the effort to match the pattern and run a pin through them all, that pin wi9ll intersect at a different point on each sheet. That pin is neither before nor after any point in time on each sheet however.

You could also imagine each sheet/layer (membrane/dimension) as different patterns entirely and it will get even more funky as far as traveling between them.


[Leap being a reference to the SciFi show 'Quantam Leap']

If I follow you, and correct me if I don't, the only way to physically go back in time in one's one same dimension/place would be for all matter (including every star, planet, asteroid, black hole, space dust, etc.) to reverse its relative motion and regress to the particular point in time in question.

Because going back in time is not just something a person does individually. It requires everybody and everything going back in time with them. True?

I was hoping for that bargain. Glad to see you posted.

Bertand Russell's The ABC of Relativity was more perception altering to me than The Bhagavad Gita, The Communist Manifesto, The Bible, Joyce, Shakespeare, or maybe even Eco's Foucault's Pendulum.

Best guess, time is not a 'fundamental' component of nature.

No, but spacetime is.

 

[von_Bismarck]

No, but spacetime is.

Maybe! There will be better answers once quantum gravity is understood. Much of the trending research is towards emergent space or emergent spacetime. It's possible to consistently rewrite the laws of physics without an explicit mention of time.

I always think about this. If Marty McFly guns his Delorean up to 88 mph and the flux capacitor send him back to 1955 then he shouldn't end up on a pine tree farm in Hill Valley he should appear somewhere in the emptiness of space where the surface of Earth was before 30 years of orbiting, revolving and moving through the universe with the rest of the solar system.

You think that scene is in the DVD extras?

Quantum says it all happens at the same but new decisions create parallel new universes. So yes we all go back in time.

Personal belief. Time is self correcting. The basic things always happen just the details get moved around. I have no proof for that what so ever.

As always good to see you Hogan.

I think you're talking about the events that led up to the Big Bang but afterwards I don't think spacetime as a concept is much in dispute right now.

[jaF0]

I consider time to be a human term to help us understand the order of when things occur or have occurred.

Which is why you really can't go back (or forward) in time. You can only change places or dimensions if you will to another where things happened in a different order. With that concept, there may indeed be a dimension out there where people use dinosaurs as excavators at a rock quarry.
