The dark energy is the energy of black holes. The mass required for becoming a black hole with C times the solar mass is C×9.458×10solar mass, and the number of atoms there is 1.133×10×C, which should be equal to the total number of atoms in the universe, i.e., 4.559×10, ...
A research team relies on measuring the number of galaxy members to determine the mass of galaxy clusters. One of the most pressing questions in cosmology is, “How much matter exists in the universe?” An international team of scientists has now succeeded in measuring the ...
solar abundances expressed as the number of atoms of the element relative to a scale upon which the abundance of hydrogen is defined as 1012. This makes comparison with, say, crustal abundances difficult, since crustal abundances are often expressed in terms of parts per million by weight. Hence...
… According to some speculations the number of distinct varieties of space—each the arena for a universe with its own laws—could exceed the total number of atoms in all the galaxies we see. … So do we live in the aftermath of one big bang among many, just as our solar system is ...

But no matter where you view the eclipse from, you need to do it safely. It's extremely dangerous to look at the sun, even if most of its light is obscured by the moon. Just as a magnifying glass can focus enough sunlight onto a leaf to start a fire, the lens in your eye can ...
the sun’s corona is by far the hottest thing the human eye can observe. it’s made of plasma—broken fragments of atoms—rather than the whole atoms that comprise the solar surface and everything else around us on earth. it’s an experience that does not seem of this life or this ...
In the first method, we need to compute the total energy of the slab, subtract the total energy of the corresponding number of atoms in an ideal bulk environment, and divide the difference by the total number of surface atoms on both sides of the slab. The only difficulty with this ...
Will the orbital energies for multielectron atoms depend on their angular momentum quantum number ℓ? (A) In the H atom, the orbital energies depend on. Interatomic Binding Quark binding in nuclear particles Radioactive β-decay Celestial mechanics, Structure of the universe Atomic forces, ...
