From our fund of knowledge there is a limit for the smallest length we can have. The answer is Planck length which is 1.61622837 × 10^-35 meters. There are bunch of things which are smaller than the atom itself, because they are the constituent of an atom. Here is a picture which includes smaller things than atom.

What is the smallest possible size something can be?
the Planck Length
The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10–35 m across.
Can something be infinitely small?
In physical reality – no. Anything infinitely small does not exist although some objects act as if they are point-like.
What is the smallest size ever?
The smallest length with any meaning is the Planck length (about 1.6 x 10–35 meter) Quarks are very very small (less than 10–19 meters)
What object is infinitely small?
Point: A point is like a dot except that it actually has no size at all; or you can say that it’s infinitely small (except that even saying infinitely small makes a point sound larger than it really is). Essentially, a point is zero-dimensional, with no height, length, or width, but you draw it as a dot, anyway.
How small is a Planck?
1.6 x 10^-35 meters
A Planck length is 1.6 x 10^-35 meters (the number 16 preceded by 34 zeroes and a decimal point) — an incomprehensibly small scale that is implicated in various aspects of physics.
How long is a Planck?
approximately 1.6 x 10–35 meters
Then keep going, a hundred million times smaller still, and you finally hit bottom: This is the Planck length, approximately 1.6 x 10–35 meters, believed by physicists to be the shortest possible length in the universe.
Can something be infinitesimally large?
“Infinitesimally large” is nonsense. There is “infinitely large,” and there is “infinitesimally small.” “Infinitely large”: A value that is beyond the countable (or uncountable) number line; the closest value to true infinity… Lim[x->inf](x).
What is the smallest particle known to man?
Quarks are the smallest particles we have come across in our scientific endeavor. The Discovery of quarks meant that protons and neutrons weren’t fundamental anymore.
Is there a smallest particle?
Quarks, the smallest particles in the universe, are far smaller and operate at much higher energy levels than the protons and neutrons in which they are found.
What is smaller than a Yoctometer?
Yoctometer is the smallest length unit under the SI international Standard of Units, and represents 1 x 10^-24 meters. The Planck length is smaller at 1.616229(38) x 10^-35 meters and represents the smallest distance of 2 locations.
What is the smallest human?
Chandra Bahadur Dangi
Share. Guinness World Records can today confirm that Chandra Bahadur Dangi from Nepal is the world’s new Shortest Living Man, measuring 54.6cm (21.5 in). Chandra is 5.3 cm shorter than Junrey Balawing of the Philippines, who measures 59.9cm (23.5 in) and was crowned world’s shortest man on his 18th birthday last June.
How tall is the shortest person in the world 2021?
Edward Nino Hernandez from Bogota, Colombia, broke the record for the shortest living man, at 2 feet 4.38 inches (72.1 cm).
How big is a quantum black hole?
Such a density would have been enough to create black holes a mere 1035 meter across (a dimension known as the Planck length) with a mass of 108 kilogram (the Planck mass). This is the lightest possible black hole according to conventional descriptions of gravity.
How big is a photon?
A photon is in shape like a thin stick if its energy is lower than the rest energy of an electron and like a plate if its radius is smaller than the classical radius of an electron. For a photon of hν=13.6 eV, the photon radius is 34.9 pm and is less than the Bohr radius.
Is Quantum Foam real?
There is no such thing as empty space; there is only ‘quantum foam,’ everywhere. Such is space-time for a quantum physicist.“Because these bubbles are so small and last for such a short time, they can never be observed directly,” says Perlman. “But they would affect light in an interesting way.”
What is faster than a Zeptosecond?
The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time. A yoctosecond (ys) is a septillionth of a second.
How fast is a yoctosecond?
A yoctosecond (ys) is a septillionth of a second or 10–24 s*. Yocto comes from the Latin/Greek word octo/οκτώ, meaning “eight”, because it is equal to 1000−8. Yocto is the smallest official SI prefix. A yoctosecond is the shortest lifetime measured, so far.
Do quantum black holes exist?
Micro black holes, also called quantum mechanical black holes or mini black holes, are hypothetical tiny black holes, for which quantum mechanical effects play an important role. The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking.
What is infinitesimally small?
adj. 1. indefinitely or exceedingly small; minute. 2. immeasurably small; less than an assignable quantity: to an infinitesimal degree.
Is infinity a number?
Infinity is not a number. Instead, it’s a kind of number. You need infinite numbers to talk about and compare amounts that are unending, but some unending amounts—some infinities—are literally bigger than others.When a number refers to how many things there are, it is called a ‘cardinal number’.
