Are there more atoms in one grain of sand than there are stars in the known universe?

No. Sand grains vary quite a but in size, but for our purposes let us consider a spherical grain of sand composed of quartz that is 1 millimeter in diameter. Such a grain would have a mass of about 0.0014 grams and given the formula of SiO2, with a molar mass of 60 grams per mole, would contain about 4.2*10^19 (42 quintillion) atoms. It is hard to estimate the number of stars in our universe and there do not appear to be any reliable sources. There are about 100 billion galaxies in the known universe and own galaxy contains an estimated 200 billion stars, but it is significantly larger than the average galaxy. If we figure the average galaxy contains about 20 billion stars then we get an estimate of 2.0*10^21 (2 sextillion) stars in the known universe universe, about 50 times the number of atoms in our sand grain.

Is the hottest star blue?
Yes, blue stars are considered to be the hottest stars in the present classification of stars in the known universe.
All the stars and galaxies are in this?
The Universe.
Is the sun a star or a bowl of fire?
It's a star. The sun is a star, and like other stars it is composed of plasma, the fourth state of matter, and the most abundant form of matter in the universe. Like other stars, inside the core of the sun, nuclear fusion takes place in which hydrogen atoms are fused into helium atoms.
How did the universe change over time?
the universe is constantly expanding, new stars and galaxies are coming into existence, and old stars are dying.
What is the inside of the universe?
my dick lol.inside the universe is the planets and stars and galaxies i think

What do you know about universe?
The universe is everything that exists. There is no sound in the universe because the sound waves cannot travel through anything. The universe is made up of nothing, there are no atoms that let the sound travel. But the planets and the stars are made up of atoms. In the universe, there are galaxies. In the galaxies are the stars, the black holes and the solar systems. The solar systems are made of planets and a star, but who knows, maybe there are 2 stars in a solar system so far from our. Everyone knows that the sun is a star. We know that the sun is the biggest thing in our solar system. But it's not the second biggest thing in the universe. Compared with other stars that are bigger, you cannot even imagine how small our sun is. Sometimes you cannot see it on images.
What happened in the universe once gravity starting condensing multitudes of hydrogen atoms?
If the hydrogen atoms get close enough together, and hot enough, they will eventually fuse into helium. This is what happens inside stars.
What is the number of particles in the universe?
It is estimated that there are 10^12 galaxies in the universe, each with about 10^12 stars. Each star has an average of 10^57 hydrogen atoms; using these estimates, the number of particles in the universe would be about 10^82.
What is all galaxies and all their stars?
It is impossible to list them all. There are 100 billion galaxies in the known universe, each containing millions to trillions of stars.
Where are stars in the universe?
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
All the stars and galaxies are in this?
The Universe.
