A Quote by Adam Riess
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 think that the equator could act as a great equalizer for all life on Earth, celebrated as the great energy belt of the planet. If all our energy grids were synchronized, the light side of the planet could provide energy for the dark side, according to the movement of the sun.
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.
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?
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.
Scale is a mental - you can say that a lounger has scale, a building has scale, or an object has scale, or a page, or whatever if it's just right. A scale is a relationship to the object and the space surrounding it. And that dialogue could be music, or it could be just noise. And that is why it is so important, the sense of scale.
Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the universe from collapsing. And so he discovered, in his theory of gravity, something like this dark energy - he called it a cosmological constant - could play this role, pushing things away.
When you buy a jacket, you pick the size to ensure it fits. Similarly, we live in a universe in which the amount of dark energy fits our biological make-up. If the amount of dark energy were substantially different from what we've measured, the environmental conditions would be inhospitable to our form of life.
Many nightclubs from this era were very loud and very dark. Plus some of the best ones were incredibly crowded. To begin with, I could seldom get back far enough to get people into frame from head to foot and when I could, people would be constantly walking in front of me all the time. Then I bought a 24-mm lens and only had to be four or five feet away.
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.
I believe we are deluded about alternative energy. The key is, whatever we do, we're going to have to do on a very modest scale. It's all about scale. We're not going to build giant wind farms with Godzilla-sized turbines all over the place. That's a fantasy.
I'm very protective of my energy. You have to protect your energy around outside sources because your positive energy can be canceled out by someone's dark energy.
There does seem to be a sense in which physics has gone beyond what human intuition can understand. We shouldn't be too surprised about that because we're evolved to understand things that move at a medium pace at a medium scale. We can't cope with the very tiny scale of quantum physics or the very large scale of relativity.
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.
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.
I went to the librarian and asked for a book about stars.... And the answer was stunning. It was that the Sun was a star but really close. The stars were suns, but so far away they were just little points of light.... The scale of the universe suddenly opened up to me. It was a kind of religious experience. There was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me.
