Vera Rubin Quotes

The existence of dark matter and dark energy are inferred from observations! They are not theoretical constructs. Though invisible, both reveal their presence through the effects that they exert on motions of celestial bodies and in the case of dark matter - the bending of light as well.

If dark matter and dark energy are 95 percent of everything, shouldn't we all be asking questions about that? What does that look like?

I am undecided whether or not the Milky Way is but one of countless others all of which form an entire system. Perhaps the light from these infinitely distant galaxies is so faint that we cannot see them.

Everything we know about the universe is studied by using telescopes or other instruments that look at visible light, infrared, ultraviolet or X-ray - different wavelengths of electromagnetic interactions. Only 4 percent of what's in the universe gives off electromagnetic radiation, so we don't have any handle on the rest.

Dark matter is particularly intriguing because it's some kind of particle - that's for sure.

There are plenty of things that are unknown, but are assumed reasonably to exist, even in the most basic sciences. Maybe 90 percent of the mass-energy in the universe is called "dark," because nobody knows what it is.

Dark matter and dark energy are two things we measure in the universe that are making things happen, and we have no idea what the cause is.

You know, dark matter matters.

When we look at the universe, what we see by eye or with our telescopes is only five percent of the universe. The rest, 95 percent is dark. Dark meaning, first of all, not visible to our instrument. Second, dark also indicates our ignorance. We don't know what's the composition of this part of the universe.

Dark matter has a gravitation effect on other objects. You can't see it, you can't feel it, but you can watch something being pulled in its direction.

In terms of the most astonishing fact about which we know nothing, there is dark matter and dark energy. We don't know what either of them is. Everything we know and love about the universe and all the laws of physics as they apply, apply to four percent of the universe. That's stunning.

I would like to mention astrophysics; in this field, the strange properties of the pulsars and quasars, and perhaps also the gravitational waves, can be considered as a challenge.

A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.

We still don't know what about 96 per cent of the universe is made of. It is dark matter and dark energy, but we have no idea what it is.

We scientists have an obsession with unification, a grand synthesis. And dark matter is an irritating missing piece.

I was already studying physics, but Sputnik steered me toward space, cosmology, the Big Bang, and elementary particles.

Dark matter is one of the dominant constituents of the universe, which piled up in certain parts of the universe due to gravity, and in those regions, galaxies were formed. It is the unseen thing that holds the universe together.

The Kecks will allow us, like no other telescope in history, to view the evolving universe that gave us birth.

Together, NASA and Hubble are opening new vistas on the universe.

Black holes are enigmatic astronomical objects, areas where the gravity is so immense that it has warped spacetime so that not even light can escape.

There must be enormous numbers of planets around the stars in the many galaxies in our observable universe. We may be sure that wonderful things are happening on these planets that the human race never will observe.

We live inside our universe and cannot get a bird's-eye view of it from outside. And we cannot even see all of our universe. Distant parts of it are expanding away from us so fast that they are invisible; they go faster than the speed of light. Having bigger telescopes to see fainter stars will not help us here: invisible is truly invisible.

Apparently, a great deal of dark, unseen material exists, whose gravitational pull is responsible for the motions of the stars and galaxies that we see.

For astronomy is not only pleasant, but also very useful to be known: it cannot be denied that this art unfolds the admirable wisdom of God.

Astronomy is a cold, desert science, with all its pompous figures,-depends a little too much on the glass-grinder, too little on the mind. 'T is of no use to show us more planets and systems. We know already what matter is, and more or less of it does not signify.
