What is the Universe expanding into..

[Galu]

Please don't mention Agnetha, it only elevates my blood pressure!

P.S. New ABBA documentary on Channel 5 at 9.00pm tonight - 'ABBA: In Their Own Words'.

 

[Bonsai]

Hard to believe ABBA’s first hit was nearly 50 yrs ago (1972).

 

[Galu]

Yes indeedy, and for their first single together, released March 1972, the name ABBA hadn't yet been invented!

 

[MITsound]

I haven't seen it come up here before.
Does anyone else believe the universe just expands into whatever it does, simply because the wave function transmuted into anything we are not equipped to understand, and therefore perceive as Nothing?

Galu, you do know, don't you, that excessive interest in Sci-Fi is considered unhealthy?
Fan of Sci-Fi? Psychologists Have You in Their Sights

Something to do with "Entitled Narcissm". But what is wrong with THAT?

Yeah...

Fantasy migration is “adaptive” – dressing up as Princess Leia or Darth Vader makes science fiction fans happy and keeps them out of trouble.

I dunno... Everyone has something... Loads of people are ecstatic when watching sweaty men kick leather balls into nets. Some other people resort to alcohol or drugs full-time.
Using the extremely cheap argument that people want to have a slight escape from everyday reality (*duh*) and use that to talk something down is just... Well, perhaps something I would only expect from a Psychologist. Maybe he's the Narcissist.

I'd rather have a more varied and balanced thing with sci-fi and diyaudio, even though it's perceived as a fair bit on the eccentric side it must be way healthier than a lot of other things.

dressing up as Princess Leia

I'd like to declare that I don't dress up as Princess Leia, or anyone else for that matter, except maybe at Halloween!

Cue gratuitous photograph of Princess Leia!

I read that only the quantum state of a spatially closed universe can be described by a wave function.

Outside of the wave function of our universe there may exist other universes.

That is, if there is such a thing as the wave function of the universe at all!

Just 30 minutes to go until NASA's major announcement about the Moon, due 4pm GMT.

BREAKING: NASA announces the “unambiguous” presence of water on the Moon.

 

[Galu]

Water has been definitively found on the Moon, NASA has said, and there are a set of “water traps” that could hold it stably.

Researchers had previously found evidence of hydration on the lunar surface. But it was unclear whether that hydrogen was in the form of hydroxyl - the chemical that makes up drain cleaners - or in the form of H2O, or water.

Now scientists have found unambiguously that there is a water on the surface.

My "universe" is that white silk bow she's wearing - as if that was needed. On the other hand, I wonder what the Qts is of "Our universe", described in that wave function...Hmmm; something about the ratio of height vs width at the base...at least I know those other universes wouldnt be good for an OB! Glad to be living in one where an OB works ;')

Don't you know that the universe more resembles a horn than an open baffle?

However, we are continually open to bafflement in this thread!

 

[system7]

I still can't get my browser to play NASA Live, but it was water, eh?

NASA’s SOFIA Discovers Water on Sunlit Surface of Moon | NASA

Not much apparently. There's a hundred times more in the Sahara desert.

Unlike previous detections of water in permanently shadowed parts of lunar craters, scientists have now detected the molecule in sunlit regions of the Moon's surface.

Speaking during a virtual teleconference, co-author Casey Honniball, postdoctoral fellow at Nasa's Goddard Space Flight Center in Maryland, said: "The amount of water is roughly equivalent to a 12-ounce bottle of water in a cubic metre of lunar soil."

But it's a start. Amazing aeroplane that SOFIA thing.

"If you travel out to the flared end of the horn, you would find yourself travelling back in on the opposite side."

This is obviously due to diffraction the designer of that horn should have made a roll-back!

Rookie error :-D

I thought a horn was an atmosphere impedance matcher - the end of it like your 50 Ohm resistor at the end of a 50 Ohm transmission line.

Maybe if we can improve the shape of the Universe's horn, when you get to the mouth - you can just keep going. Or at least apparently.

 

[Galu]

...but it was water, eh?

Yes - and I am so disappointed that the Moon hasn't been discovered to be hollow after all - especially after buying the T-shirt!

jjasniew sounds like a Telecoms man, like myself.

I was pondering the problems of the Universe tonight. Clearly we are stuck in a bog:

Bizarre ‘Dark Fluid’ With Negative Mass Could Dominate the Universe

Don't waste time on this crackpot theory about negative mass and Dark Matter and Dark Energy. Makes no sense at all.

I was hoping we could spend more time on Information Theory.

All this notion about Energy, Momentum, Time and Distance is just a dead-end. So far I have Information Theory, Geometry and something else on the go.

This is 2D function of a complex variable aka Butterworth Filters:

Amazingly it crops up in the latest scientific wheeze about room-temperature superconductivity with graphene sheets:

With a Simple Twist, a ‘Magic’ Material Is Now the Big Thing in Physics

I like that.

 

[Bonsai]

I find the concept of time fascinating. Travel at c and the universe is at most 1-2 LY in diameter. Travel at << c and it’s billions of LY in diameter. Time, energy, matter. Interesting stuff!

 

[TNT]

I hoped for cheese.
