It's mathematically heavy, and there's disagreement on just what a 'wavefunction' describes about a particle, but the basic idea is that an unmeasured particle has a wide range of possible states, and these states 'collapse' to just a few states when they are interfered with.
I came across these two articles on another thread which suggests, IMO, that much of what is considered to be missing mass isnt really missing, and much of what is considered to be dark matter isnt really dark. Do you agree with this suggestion?I'm enjoying these physics-related threads so...
Ask a physicist anything.
I've seen those articles before, and its hardly accounts for 'much' of dark matter. You've pushed the amount from 97% of the universe to 96%, if that.I came across these two articles on another thread which suggests, IMO, that much of what is considered to be missing mass isnt really missing, and much of what is considered to be dark matter isnt really dark.

Maybe. But, what I find interesting is that you are seeing what cannot be seen and what can be seen you are not seeing. Makes one wonder how mush more you are not seeing that can be seen.I've seen those articles before, and its hardly accounts for 'much' of dark matter.

The was not my intent. See above.You're grabbing at straws if you think this invalidates dark matter hypotheses.
You are. Wasn't me. But that's OK.And besides, if you're going to rail against modern techniques (I think it was you who called them 'primitive', though I could be wrong),
Maybe I'm "cherry-picking" my findings because the cherries are made of normal matter that can be found.why not turn around and say that these new findings are also hopelessly wrong? Methinks the anti-dark-matter group are cherry-picking their findings.
Yes, because the molecules are closer together. The sound is also clearer, because there is less thermal motion to muffle the sound (think of shouting in the wind: all that motion makes it hard to hear).Does sound travel faster through cold air?
That's the power of good evidence. I believe in atoms and cells and EM waves, though I can't see any of that.Maybe. But, what I find interesting is that you are seeing what cannot be seen
Such as?and what can be seen you are not seeing.
No, you're cherry-picking in that you have a double-standard when it comes to evaluating evidence and criticising techniques.Maybe I'm "cherry-picking" my findings because the cherries are made of normal matter that can be found.

I've never noticed that, to be honest. Maybe British theatres are heated differently. It could be that yours are made cooler to combat all that body heat, but when there's few people in there, it gets a bit nippy.Is that why theaters are always so cold? Or is that merely for comfort?
What's the best shape for a large room to be for the best acoustics?
I can think of 'spryly', provided a 'vowel' is either a, e, i, o, or u. If you want a word without vowel sounds, then 'church' comes to mind, if have my accent (I come from Somerset, so I have a rather rhotic pronunciation).And what's the longest word in the english language without any vowels? Mwahahahahah!

But I doubt it's to do with the acoustics. Cold air isn't that much better at transmitting sound.
Seven questions that keep physicists up at night - space - 23 October 2009 - New Scientist
There are the 7 questions that supposedly keep you guys/gals up at night. Enjoy.
It's very likely, given how currents flow around the American continent would be completely altered. I daresay the Suez and Panama canals have likely done that already, to an extent.If you made the panama canal really big and deep, would it affect sea currents?
Experimentally. According to my calculations, if you know how much of an atom you have at two different times (N[sub]1[/sub] at time t[sub]1[/sub], and N[sub]2[/sub] at time t[sub]2[/sub]), then the half-life of that atom is given by:How is the half-life of an atom determined?

Fixed.4% normal matter, 25% dark matter (based on evidence and observation), and the rest as dark energy (also based on evidence and observation)
Incomplete? Sure. But inadequate? Please.doesnt say much for the mainstream model of the universe, which they themselves readily admit is far from adequate.
Which betrays your utter lack of understanding of how science works.What I find interesting is that they admit there is something theoretically wrong but then try to make being wrong seem like a good thing scientifically.
