Small

[Gingerbaker]

As everything beyond our universe is infinitely large, does that mean also that things can be infinitely small. So you could have an infinite amount of small universes inside one of our known atoms…quarks…smaller and smaller…smaller…..?

in maths rather than in real life

[bobbinwales]

yes- numbers can be infinately small getting closer to zeroe as we count back but never quite getting there 0.1, 0.01, 0.001, etc then eventually 0.000000000000000001 and so it goes on. and atoms are tiny but there made up of smaller things that are so small there weight is zeroe

Tonight Matthew, I'm going to be Dan Quayle.

It seems to me quite likely that any new "small stuff" will stop at some point. Although that's not based on anything particularly concrete.

If you were wanting to think about it from the point of view of a designer, then they'd have to start somewhere, whereas infinite regress downwards means that they'd never be able to get the Universe off the ground. It's (sort of) the same if the Universe just spontaneously comes into existence, on the basis that nothing should be be complicated than it needs to be. At some point, ever-finer structure no longer really "adds" anything.

If something were literally infinitesimal, how would it be measured?

[naomi24]

infinitesimal by whose measurements? Multiple universes? Maybe there’s a universe where entirely different laws and standards apply. Just musing.

I remember as a junior schoolboy watching a film starting from Earth and zooming out into the cosmos and then reversing back to Earth and then into cells, molecules, atoms etc.
Would love to find it again...

[nailit]

Once we've divide electrons, etc
how far do we go?
Fascinating topic.

Something about Buddhism resonates with me here
(Though I'm not a Buddhist).
Eternity works both ways.
You cant suffer an eternity of hell
(or suffer an eternity of heaven)
If we are not eternal.
(IE, have always existed!)
If we BEGIN to exist then we are not eternal...
Anyway, going of the post...

No, the planck length is the smallest possible.

Could ask God Nailit ;-)

this is part of Men in Black - innit
the cat has universes in the bell around its neck....

the other bit I doubted was Michael Jackson as a man in black ( agent M)

19.07 Nailit/ Could it have been "Powers of Ten" 1977

//Could ask God Nailit ;-)//
He never replies though....

[nailit]

"Powers of Ten" 1977
It was something very similar....
Thank you

Thank you also.
Sorry for high-jacking your post Small.

ToraToraTora, what do you mean by saying the Planch length is the smallest possible? Is space, like, split up into tiny cubes? It sounds weird, I thought space was meant to be continuous, do we actually know that it isn't?

[THECORBYLOON]

TORATORATORA, "No, the planck length is the smallest possible.

The Planck length might be the smallest measurable length but that does not mean there is nothing smaller.

Have a read of this on Quora,
