A Quote by Neil deGrasse Tyson

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. — © Neil deGrasse Tyson
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.
I got fascinated by the idea that our universe itself is comprised mostly of dark matter and dark energy. Things that we can't perceive at all, and we've only discovered that relatively recently. So it's almost as if our universe is the foam on the ocean of things that we can't see, or know, or perceive, and yet we feel the affects of those things right and left.
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.
Science has proved that everything is energy, and now they have dark energy, dark matter. They don't call it all-embracing consciousness; they call it dark because they can't measure it. You know, paint it black.
We account for all the matter and energy that we're familiar with, measure up how much gravity it should have, it's one-sixth of the gravity that's actually operating on the universe. We call that dark matter. It really should be called dark gravity. We don't know what that is.
Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.
I want to know what dark matter and dark energy are comprised of. They remain a mystery, a complete mystery. No one is any closer to solving the problem than when these two things were discovered.
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.
You know, there's black holes and what - could there be wormholes? Could - might there be a multi-verse? These are all fascinating frontiers. What is the nature of dark matter and dark energy? And what was around before the universe? And do we have access to higher dimensions?
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.
Whenever dark things happen in my life, there is always some dark humour.
The missing link in cosmology is the nature of dark matter and dark energy.
You go, dark energy! Go on, dark matter. They don't understand you, dark matter. They don't get you.
In the Art of Dreaming Don Juan tells Carlos, "... most of our energy goes into upholding our importance... if we were capable of losing some of that importance, two extraordinary things would happen to us. One, we would free our energy from trying to maintain the illusory idea of our grandeur; and two we would provide ourselves with enough energy to ... catch a glimpse of the actual grandeur of the universe."
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?
However, one new theory says that dark matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain dark matter.
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.
