Quotes About Universe

We are seeing these nearby stars, not as they are at the present moment, but as they were 4 years ago

When I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small, 'cause they're small and the Universe is big, but I feel big because my atoms came from those stars.

The universe is knowable...

The universe is knowable and what one need not apeal to mystical, magical forces to account for things

Out of ninety-four naturally occurring elements, hydrogen lays claim to more than two-thirds of all atoms in the human body, and more than ninety percent of all atoms in the cosmos, on all scales, right on down to the solar system.

When I pore over the data that establish the mysterious prescence of dark matter and dark energy throughout the universe, sometimes I forget that every day- every twenty a fourth out rotation on Earth- people get killed in the name of someone else's conception of God, and that some people who do not kill in the name of God, kill in the name of needs or wants of political dogma.

Dark matter particles should be passing through your body right now.

After nine billion years of such enrichment, in an undistinguished part of the universe (the outskirts of the Virgo Supercluster) in an undistinguished galaxy (the Milky Way) in an undistinguished region (the Orion Arm), an undistinguished star (the Sun) was born.

When I pause and reflect on our expanding universe, with its galaxies hurtling away from one another, embedded within the ever-stretching, four-dimensional fabric of space and time, sometimes I forget that uncounted people walk this Earth without food or shelter, and that children are disproportionately represented among them.

We begin with the stars, then ascend up and away out to the galaxy, the universe, and beyond. What did Buzz Lightyear say in Toy Story? "To Infinity and Beyond!" It's a big universe. I

You can picture the universe as an enormous loaf of raisin bread rising in the oven

however big the world is—in our hearts, our minds, and our outsized digital maps—the universe is even bigger. A depressing thought to some, but a liberating thought to me.

Astrobiologists now believe that the existence of life throughout the universe requires: 1. a source of energy; 2. a type of atom that allows complex structures to exist; 3. a liquid solvent in which molecules can float and interact; and 4. sufficient time for life to arise and to evolve.

The four most common, chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth, with carbon serving as the foundation of biochemistry. We do not simply live in this universe. The universe lives within us.

We do not simply live in this universe. The universe lives within us. That

Merlin prefers to think of space as the regions between all the particles of all the atoms of the universe.

Can space exist in the absence of matter, if matter defines the edge of space?" Merlin

In particular, a quantity known as the fine-structure constant, which controls the basic fingerprinting for every element, must have remained unchanged for billions of years. Of

People who believe they are ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the universe. What

Our profound areas of ignorance notwithstanding, today, as never before, cosmology has an anchor, because the CMB reveals the portal through which we all walked. It's a point where interesting physics happened, and where we learned about the universe before and after its light was set free.

What if the universe was always there, in a state or condition we have yet to identify - a multiverse, for instance, that continually births universes? Or what if the universe just popped into existence from nothing? Or what if everything we know and love were just a computer simulation rendered for entertainment by a super-intelligent alien species?
