What is the Universe expanding into..

[popilin]

But, it's important because the speed is constant and the red shift comes be because the universe is expanding, not because light is slowing down.

This whole time I thought we were discussing the constant of C, capacitors

This is all known and adds no news to this discussion

And this adds some? ...With man's universal sensitivity that might have a 'fracking' impact subconsciously over a chain-reaction. ...Thought of that?

I ran across a wonderful phrase yesterday: "Geysers of derp."

What that means? ...I don't want to goggle it.

Actually, Bob that one (derp) is relatively safe - and something at which I'm well past my 10,000hrs of practice

But I won't let that detract me from my trajectory (universe's x-pansion discussion among my peers).
Scientists and physicists and astronomers and theorists and philosopher stones and artists and musicians and audio designers, ...all have a say on reality.

When you make a final statement, a judgement; that's when you stop evolving and discovering wider horizons.

Nothing in the universe is absolute, nothing.

...And because I am interested in our universe, right here right now, and also because I am interested in reading, and listening, and learning, and discovering, and because I care about everything; families, expansions, humanity, sociology, technology, musicology, procreation, prosperity, and all that jazz ...

There's a critical distance after which it becomes quite entertaining. Maybe critical isn't the right word.

The film Event Horizon holds some perspective. I recommend.

 

[popilin]

Certainly Misner, Thorne, and Wheeler's gravitation "phonebook" was some tough work for me as an undergrad.

Then you don't know true suffering

S.W. Hawking, G.F.R. Ellis – The large scale structure of space-time

Not a "phonebook" but a "brick-book", a true torture instrument, although difficult to believe, the same author has written a charming book, easy to read, and it can help to answer the original question of this thread

S.W. Hawking - A Brief History of Time

please take the trouble to rethink your statement.. the expanding universe is not the only reason for red-shift. Mass (gravitational pull) influences the propagation of light. Accurate laser-measurements indicated that passing a large mass slows them down a bit. We've moved on since Einstein..

Can you point me to a paper where this is reported?

Do you remember the CERN experiment from a few years ago, where they measured speed of light was not what it was supposed to be? It was off by a minute amount and it created a furore in the scientific world, and in the press. After some investigation, the problem was measurement error.

Here is the wiki entry for c. In a vacuum its constant.

Speed of light - Wikipedia, the free encyclopedia

And if if were not so, it's not just Einstein that would be wrong about a whole lot of things. Throw out Michaelson-Morely, Maxwell, Planck, Heisenberg, Heavyside, and more recently people like Hawking et al.

You can't claim the properties around a fundamental physical constant like c are wrong without some pretty heavy proof. You will have to make a career out of it I am afraid.

In a sense, he's right- there are gravitational red shifts. But they are distinct and different than the cosmological redshift, i.e., they're local phenomena.

Great flick, and spatially bloody.

Critics are always quite entertaining, most of the time, hardly rarely.

I think you refer to an experiment with neutrinos, first results announced superluminal neutrinos, i.e. v > c, but was a bad optic fibre connector.

And if if were not so, it's not just Einstein that would be wrong about a whole lot of things. Throw out Michaelson-Morely, Maxwell, Planck, Heisenberg, Heavyside, and more recently people like Hawking et al.

Well, don't worry, if someday would result that c it is not constant, it shouldn't be the end of physics, just some changes.

Think in a western movie, Einstein is at the saloon, and bad guys enter every day to challenge him, so far nobody could with him…

 

[NorthStar]

Einstein was an outlaw?

 

[popilin]

No, he was the sheriff, and he was at the saloon only to drink a glass of milk.

Oh, I just thought for a fast light second.
