Our local NPR station has been reporting on positive proof of the existence of gravitational waves . Einstein predicted the possibility of them 100 years ago . Geez , how amazingly brilliant was the man?
:bow: :bow: :bow:

Very bright! But not perfectly so, he missed the call on Quantum Theory!
Now, can we learn to surf those things?

Yes , on a Max Planck :rolleyes:

I don't think I could handle the weight of a Max; need a shorter Planck.

Mind boggling. 1.2 billion years ago, and 1.2 billion light years away, two black holes each about 30 times as massive as the Sun executed their death spiral, releasing energy equal to three times the mass of the Sun in a fraction of a second. That energy outshone all the stars in the observable universe for that fraction of second, by fifty times.
And from here it all amounted to a comical little chirp.
So it goes.

Ahh...
But if QM theory is valid - as it seems to be - then locality is an illusion caused by perceptions of spacetime limitations. And those great things happening way out there may be more important to us that we can currently observe.
hey, and you guys are awesome!
-
We just don't want to appear Bohring :rolleyes:
Seriously , the thing that amazes me , Einstein and his peers jumped physics ahead hundreds of years. Very unusual in the world of science .

Yes they did. All our current physics is built upon two bases: Relativity, and Quantum Theory. All our current work is in the area of confirmation and refinement. There has been nothing like the physics of the late 19th into the early 20th centuries.
(I kinda like physics)

Truly is mind boggling. He was as they say "a bright cookie".
A couple of weeks ago I went to an exhibition of Leonadp Da Vinci models constructed from his drawings. Another bright cookie.

My heroes tend to be these bright cookies. Blazing beacons in the darkness of the world.
-
Quantum physics makes my brain hurt. Einsteinian physics, I can get my head around.
-
Is it QM's indeterminacy that is the problem?

Well, we all shine on, like the moon and the stars and the Sun!
Even when we move a hand we generate a gravity wave that ripples out forever, or almost forever.

Exact! All is connected. We are just beginning to grasp the depth of this concept.

Yes. The ramifications are mind boggling.

That indeterminacy was why Einstein had his reservations , he liked things more clear cut .
Dusty

You guys are wonderful.
Yes, Einstein hated QM indeterminacy. He ought to have embraced it! Only in a non strictly mechanistic universe could we have any version of free will, indeed an indeterminate universe demands it. Probabilities are the best of all philosophical roots.
-
Laura , Einstein's greatest talent was his ability to design experiments that proved his theories . QM presents a roadblock in that regard , or did until recently . The Large Hadron collider will allow science to design experiments that will open up a whole new window into QM , maybe even leading to some form of unified theory . Seems we are entering another period of great advancement in our understanding of the universe , or universes .

This is where I bow out. Thanks for the brief interlude of high-brow discussion. :thumb:

Quantum physics is easy. Everything is just Bozos and Futons. :evil:

It all works on PFM anyway.

Not giving the man enough credit. He did get the Nobel, after all, for explaining the photoelectric effect, a purely quantum mechanical phenomenon. At the time, the Nobel committee wasn't quite convinced that general relativity was real.

I don't blame em. Quantum mechanics makes my head hurt, too.. :smiley:

To go from relativity to physics required a Quantum Leap....

This is interesting , an unexpected result of quantum thinking

Personally, I'd describe that a little differently.
The ancient Shamans understood that " all was connected"
What we've been been doing since Darwin is proving and
documenting what they knew and using it in a different
way, with different perspective, outlook and purpose.
The Circle turns.

There are very few real good mechanics around any more much less a quantum mechanic. Maybe they work on Beemers and Audis.
I think the Native Americans had it right in that the universe is a big circle, they are descendants of ancient aliens you know.

As you can tell, the jist of this post is way over my head. Hope Pete is getting all of the 8 valvers sorted in his area.

Too many great replies here of philosophical import or great humour! Keep it up!
Yes...Einstein's Photoelectric Theory. That is where QM began, and then Einstein disliked it so much that he and two colleagues constructed for an ad absurdum argument against QM the EPR Paradox. But in another of nature's great ironies, that paradox actually works. Indeed, I think last year some real smart head experimenters successfully used it to transfer information.
This universe is a pretty nifty place.

I haven't been fishin' in so long that I have barely useful recollections. I think something called bait goes on a hook?

That joke blew right on past me like an unsensed gravitational wave!

I am not an expert in science. But gravity and magnetism fascinate me. Gravity is so much weaker than magnetism, I believe by a factor of 5. May be wrong. Just standing outside at night and looking up is enough for me to realize how insignificant we truly are yet unique in many ways. Even the concept of time is insignificant. My head hurts now.
My question is, Is the study of gravity done out of curiosity or is there a need to know? Are we looking for Some great discovery that will change our lives for the better. Considering the deeper we look, the further we move away from our future. Or is it the more we see in the future, the further we see into the past. Which is to late by then. Now my head really hurts.

Although it is a rare scientific discovery that fails to bring into the world some potential new use; this is pure science at the moment. These guys simply want to know.

Here's yer Guzzi connection. There used to be a Loopframe sidecar guy named Steele McWrench. He was a Quantum Mechanic. Had a cat named Otto who used to belong to a guy named Schroedinger.

I can't top that!

I guess in some way, Gravity is God. With out it, We would not exist. It is after all what is holding everything together as we know it. It is a window into our past the keeps on giving.

I can't too deep into this stuff, but Einstein was truly bent in his mind to be able to comprehend and predict things that only 75 or 100 years later they are proving him correct. I never understood how you can warp time but it was proven with an experiment involving perfect watches. I read the other day that if scientists didn't allow for his time warp factor between the earth and our GPS satellites, your GPS would be off by 6 miles.

I read that, too. Beam me up, Scotty. :smiley:
