The Scale of the Universe (Damndest Thing I Ever Saw)

Mind blowing when you think that everything from the neutrino to the present universe horizon is confirmed.

[tazmic]

I was surprised to see how big a neutrino is, compared to... the 'smallest physically meaning span'. Huge!

It interests me to note that between the neutrino and 'everything' we are kinda in the middle of the scale. So there's just as much out there as in here too!

I've seen far more complex attempts at this display, that weren't nearly as good. A great find, thanks.

There are earthworms 7 meters long?

And why can't I subdivide a Planck length? Who says it makes "no physical sense"? I mean if Zeno's suction cup dart is one planck length from my forehead doesn't it have to travel half a planck length before it reaches it's target?

And then it would have to travel half that remaining distance (i.e., 1/4 Planck length) and then half that (i.e., 1/8 Planck length), and so on ad infinitum. In other words, neither Zeno's nor anyone else's arrow can ever reach your forehead. Which is reassuring, but dangerously so, because of course arrows have often, in fact, reached foreheads.

Not that I understand this myself! It is all highly weird.

The Modernity of Zeno’s Paradoxes

If it were that close it would already be there, and if it only moved half a plank length it would be in the same place.

My turn for a question. Is not claiming a minimum sensible distance the same as stating time is discrete?

But it's getting twice as 'fast' each time. If you agree that the arrow can always travel 'half the remaining distance' then it can go as far as you like. 1 + 1/2 + 1/4 +... = 2. And that can be 2 anything.

[MacCruiskeen]

1 + 1/2 + 1/4 +... = 2.

Surely not. It never quite gets there. Like pi, it never ends.

1.99999999999999999999999999999999999999999999999999999999999 is still less than 2. (Or is it, if you add enough 9s? That's the question.)

It has to do with equations. Expert math can't equate that seemingly infinitely small. Probably the solutions have all resulted in errors. Like the old skool superstring theory. Calculations came up with all manner of various numbers of dimensions, but the exact number couldn't be completely known, let alone envisioned, because various variables plugged in gave solutions, but it was (when I was reading about that shit [Micheo Kaku's Hyperspace]) unknowable which answer was correct.

Now, grant me that I am a mathematical idiot and only enjoy reading about the theories. I have never been able to sit through one damned upper level math class in all of my life. Thus I never graduated college. But into this stuff, I am.

Thanks for the link!

From the comments in Mac's link:

'in Wheeler-DeWitt cosmology the fundamental Planck length coexists with continuous space and time.'

So now I know

That's what the ... meant. As it takes half the amount of time to travel half the previous distance there is 'all the time in the world' to get to the end, and it would only take a finite amount of time do it.

Thanks. I had a brief mental... something* there, where I thought I understood it.

*Explosion?

Cool (I was hoping someone would come along with a better explanation, as it's bed time for me)

But, Damn what a cool site:

"In the enigmatic Canon 1 a 2 from J. S. Bach’s “Musical Offering” (1747) (also known as “crab canon” or “canon cancrizans”), the manuscript shows a single score, whose beginning joins with the end. This space is topologically equivalent to a bundle of the line segment over the circle, known as a Möbius strip. The simultaneous performance of the deeply related forward and backward paths gives appearance to two voices, whose symmetry determines a reversible evolution. A musical universe is built and then is “unplayed” back into silence."

Thanks for that.

it's fractal dude, elephants all the way down....

ever see a big wave, in the ocean?

look close at the surface, there's little waves there too ...

Thanks for the best LULZ I've had all day...needed that.

It's about attraction, see...

There are earthworms 7 meters long?

I mean, I'm just attracted to the idea of catching the fish that bites on to that 7 meter long earthwarm.

Attractions, man. Every(w)here...attractions...
