A Quote by John D. Barrow
If all the stars and galaxies in the universe today were smoothed out into a uniform sea of atoms, there would only be about one atom in every cubic meter of space.

Every atom is trying to go and join itself to the next atom. Atoms after atoms combine, making huge balls, the earths, the suns, the moons, the stars, the planets. They in their turn, are trying to rush towards each other, and at last, we know that the whole universe, mental and material, will be fused into one.
It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom's way of knowing about atoms.

The James Webb Space Telescope was specifically designed to see the first stars and galaxies that were formed in the universe. So we're gonna see the snapshot of when stars started. When galaxies started. The very first moments of the universe. And my bet? There's gonna be some big surprises.
If the expansion of the space of the universe is uniform in all directions, an observer located in anyone of the galaxies will see all other galaxies running away from him at velocities proportional to their distances from the observer.
You know; when I look at the night sky and I see this enormous splendor of stars and galaxies, I sometimes ask the question, well how many worlds are we talking about? Well do the math, there are about 100 billion galaxies that are in the visible universe and each galaxy in turn contains about 100 billion stars, you multiply and you get about ten billion trillion stars. Well I think it is the height of arrogance to believe that we are alone in the universe, my attitude is that the universe is teaming, teaming with different kinds of life forms

Every field of astrophysics - whether it's our local neighborhood of planets, nearby stars and their attendant planets, galaxies, clusters of galaxies, out to the edge of the universe - every field has questions that are awaiting the power of Hubble.
I try to identify myself with the atoms ... I ask what I would do If I were a carbon atom or a sodium atom.
There is enough energy in a single cubic meter of space to boil all the oceans in the world.
We have stars, planets and galaxies in space. There's lots of nothingness out there, but it's really not. There's gas, dust and other bits of matter floating around emptier' areas of the universe, but you can't see it very easily.
The astronomer who catalogues the stars cannot add one atom to the universe; the poet can call an universe from the atom.
I love individuals. I think people are terrific as I meet and get to know them. I like imagination. I like the freedom that this society manages to parcel out to us in the midst of the rest of what they do to you. I also like thinking about the fact that the atoms in me are the same atoms that are in all the rest of the universe, and that every one of those atoms came from the middle of a star. In other words, it's only me out there.
The chemist in America has in general been content with what I have called a loafer electron theory. He has imagined the electrons sitting around on dry goods boxes at every corner [viz. the cubic atom], ready to shake hands with, or hold on to similar loafer electrons in other atoms.
The stars begin to fade like guttering candles and are snuffed out one by one. Out in the depths of space the great celestial cities, the galaxies cluttered with the memorabilia of ages, are gradually dying. Tens of billions of years pass in the growing darkness ... of a universe condemned to become a galactic graveyard.
In some sense, what you might have suspected from the first day of high-school chemistry is true: The periodic table is a colossal waste of time. Nine out of every 10 atoms in the universe are hydrogen, the first element and the major constituent of stars. The other 10 percent of all atoms are helium.
