Is an atom just empty space?
Atoms are not mostly empty space because there is no such thing as purely empty space. Atoms are filled with electrons. It’s true that a large percentage of the atom’s mass is concentrated in its tiny nucleus, but that does not imply that the rest of the atom is empty.
Is the sun an atom?
Like any star in its prime, the sun consists mainly of hydrogen atoms fusing two by two into helium, unleashing immense energy in the process. But it’s the sun’s tiny concentration of heavier elements, which astronomers call metals, that controls its fate.
What is beyond an atom?
Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure.
Is Earth an atom compared to the universe?
(1e-10 / 5.56e-13 = 179.8) approx a 180th of the size of an atom!!! So if the entire observable universe is the size of planet earth (12000km diameter), planet earth would take a 180th part of an atom within this universe!! A simple atom (hydrogen) has 1 proton in it’s nucleus and 1 electron circling around it.
Is an atom a chemical?
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms….
| Atom | |
|---|---|
| Smallest recognized division of a chemical element | |
| Properties | |
| Mass range | 1.67×10−27 to 4.52×10−25 kg |
| Electric charge | zero (neutral), or ion charge |
Are solar systems atoms in a larger universe?
Following that train of thought, perhaps solar systems are actually “atoms” in a much larger universe. Some stars are very large and some are much smaller than our Sun—just as some atomic nuclei are large and some are small, depending on their atomic number and weight.
Could there be an atom inside another universe?
Another reason why the universe could never be an atom inside another universe is quantum mechanics. According to quantum mechanics, the electrons in an atom are not on one specific position, but they are everywhere around the nucleus at the same time]
Why can’t galaxies exist at the subatomic level?
This basically tells you you just cannot scale everything and assume nature works the same. So galaxies cannot exist at a subatomic level. And if matter becomes too massive or dense, it can even break the fabric of space-time, leading to a singularity, the point of infinite space time curvature.
What is the difference between the Milky Way galaxy and universe?
Most of the stars in our galaxy are thought to host their own families of planets. The Milky Way galaxy is just one of billion of galaxies in the universe, The universe is a vast expanse of space which contains all of everything in existence. The universe contains all of the galaxies, stars, and planets.
