Space is not necessarily infinitely divisible. Quantum mechanics arises partly from the simple notion that not everything can infinitely divisible--that there are smallest possible pieces of things, called quanta.On the other hand, just because something cannot be subdivided into smaller pieces doesn't mean that it can't get any smaller.

If it were possible to measure the Planck length in a local frame of reference then every frame of reference would make the same measurement. If length contraction has occurred in a particular frame then a remote observer would observer 1 Planck square area to be rectangular rather than square.

From what I understand about the quantum state, whether Planck Length, Planck Mass, or Planck Time, such units are not necessarily the smallest units possible. They are simply the smallest measure of such units which we can calculate mathematically given the criteria available for such calculations, such as the speed of light.

When we look in to space let say with a telescope, no mater how many times we zoom in theirs always more. Since space is infinite those that applies to microscope as wall?

If space is infinite that would mean no mater how far we zoom in with a microscope there will always bee more (infinite) that would mean that theirs things so tiny that atom would be like the galaxy to some other tiny particles.

But it may also be that space is quantized, whether that is at the Planck limit or smaller we probably can't know...

I'd like to welcome you to the forum. []I don't understand the question Since space is infinite those that applies to microscope as wall? so can you please restate it for me please? I have the feeling that you're confusing the terms telescope and microscope. Thank you.If you're referring to a microscope then I can't see what makes you think that looking into a microscope will tell you anything about space being infinite. Please explain. Thanks.Quote from: D If space is infinite that would mean no mater how far we zoom in with a microscope there will always bee more (infinite) that would mean that theirs things so tiny that atom would be like the galaxy to some other tiny particles.If indeed you're referring to microscope then you have the wrong idea about space being infinite. Also, an atom in no way resembles a galaxy. A galaxy is understood in classical terms while an atom can only be understood using quantum mechanics.

now what im saying is that there could bee things so small that the atom would seam like a galaxy in comperasing.
