10^−35Planck length

The Great Wall of Sloan is the 3rd largest supercluster of galaxies in the Universe.

The length of Planck would be the length from which gravity would begin to produce quantum effects.

Thetys is the 5th largest satellite of Saturn.

Beyond yotta

It is not impossible that the Universe itself is part of a cluster of universes in a global universe.

Similarly, there could be alternative universes in parallel dimensions, dimensional panels with sub-spaces.

Beyond the Universe: Even if the Universe is unique, it remains the void that surrounds the Universe and which by definition has an infinite size, a measure that goes against our usual conception of matter, space, energy and time.

Beyond the yocto

The Higgs boson, if it exists, would be the same size as a quark.

Planck’s length would be, according to physicists, the smallest measurable size.

It has long been believed that an atom was the limit of the infinitely small (atom signifying indivisible). In fact it is not, the infinitely small is like the infinitely great, it could well be infinite. This also upsets the concept of finished object preconceived by our brain.
