Astronomers classify all of this stuff as baryonic matter, and they (and we) know its most fundamental unit as the atom, which itself is composed of even
smaller subatomic particles, such as protons, neutrons and electrons.
Protons are essentially accumulations of even
smaller subatomic particles called quarks and gluons, which are bound together by interactions known in physics parlance as the strong force.
a very
small subatomic particle called NEUTRINOS have rendered radiometric dating useless.
Just as his earlier work paved the way to harnessing
the smallest subatomic forces, the general theory opened up an understanding of the largest of all things, from the formative Big Bang of the universe to its mysterious black holes.
What physicists learn from these collisions may help us understand more about why the physical world works the way it does, from
the smallest subatomic particles, to the largest stars.

A second response was to make the

subatomic world.
Theorists had predicted that neutrinos, nearly massless
subatomic particles that barely interact with matter, should be released during the core collapse, and in no
small quantity.
She traces those anomalies back to a fraction of a fraction of a second after the Big Bang, when our universe was so
small that it behaved like a
subatomic particle, dominated by quantum physics.
Hameroff suggests the most meaningful action happens at the impossibly
small quantum level, where
subatomic particles like photons and electrons exhibit bizarre behavior.
Our current theory of gravity — Einstein's general theory of relativity — and our current theory of the behavior of atoms and
subatomic particles — quantum mechanics — both work fantastically well in their respective domains: general relativity for big things, quantum mechanics for
small things.
Called the quantum phonon, this
subatomic acoustical wave can be detected only by intricate instruments that distinguish pure silence from its

Astrophysical giants several times the mass of the sun and midget black holes
smaller than a
subatomic particle could provide glimpses of an extra-dimensional existence.
For decades, physicists thought that the
subatomic particles called neutrinos were, in fact, the massless particles that Weyl had predicted — a possibility that was ultimately eliminated by the 1998 discovery that neutrinos do have a
small mass.
To peer inside the kerogen, they used

The latter explains the world of the very
small, the microscopic realm of atoms and
subatomic particles.
That is because, on some basic level, atoms and all
subatomic things are invisible — not just in the trivial sense that they are too
small to see but also in that, according to quantum physics, they do not have a well - defined position.
When we zoom closer into matter, by probing at
smaller distances, the
subatomic world unfolds.
According to the big bang theory, one of the main contenders vying to explain how the universe came to be, all the matter in the cosmos — all of space itself — existed in a form
smaller than a
subatomic particle.
More recently a team of Stanford University researchers led by Hari Manoharan were able to encode 35 bits of information per electron and write letters so
small they are composed of
subatomic bits of matter only 0.3 nanometers wide, or roughly one third of a billionth of a meter.
At the end of the nineteenth century, scientists would show that atoms were actually made up of
smaller, «
subatomic» pieces, which smashed the billiard - ball concept of the atom (see our Atomic Theory I: The Early Days module).
baryons
Subatomic particles made from three
smaller units called quarks.
To do so, he had to pull the viewer into a world
smaller than herself, into a simulacrum of the
subatomic, into the visceral, into what he called «articulated space».
