A Quote by Mark Helprin

When you die, you know, you hear the insistent pounding that defines all things, whether of matter or energy, since there is nothing in the universe, really, but proportion.
The ancient intuition that all matter, all "reality," is energy, that all phenomena, including time and space, are mere crystallizations of mind, is an idea with which few physicists have quarreled since the theory of relativity first called into question the separate identities of energy and matter. Today most scientists would agree with the ancient Hindus that nothing exists or is destroyed, things merely change shape or form; that matter is insubstantial in origin, a temporary aggregate of he pervasive energy that animates the electron.
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 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.
There is nothing -- absolutely nothing -- half so much worth doing as simply messing about in boats. In or out of 'em, it doesn't matter. Nothing seems really to matter, that's the charm of it. Whether you get away, or whether you don't; whether you arrive at your destination or whether you reach somewhere else, or whether you never get anywhere at all, you're always busy, and you never do anything in particular; and when you've done it there's always something else to do, and you can do it if you like, but you'd much better not.
In astrophysics, we care about how matter, motion and energy manifest in objects and phenomenon in the universe. Stars are born. They live out their lives. They die. Some of the ones that die explode. Our sun will not be one of those, but it will die. And it'll take Earth with us. So we make sure we have other destinations in mind when that happens. And I've got it on my calendar.
If the total energy of the universe must always remain zero, and it costs energy to create a body, how can a whole universe be created from nothing?
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.
In fact, current cosmological observations indicate that the average density of matter and energy in the universe is equal, within measurement errors, to the critical density for which the total energy of the universe was exactly zero at the beginning.
I know I've been lucky. But it's what you do with that luck afterwards that really defines whether you stick around.
There's nothing that defines who you are more than boundaries, whether you cross them or not, in every aspect of your life, and horror is a really great boundary.
We are all made of flesh, of matter. And at the end, this matter is dissolved in light, and transformed into energy. It’s the Einstein formula. Energy is nothing but matter that is moving at the speed of light, squared
There is a world of created beings - living things, animals, entelechies, and souls - in the least part of matter.... Thus there is nothing waste, nothing sterile, nothing dead in the universe; no chaos, no confusions, save in appearance.
If what you mean by the word "matter" be only the unknown support of unknown qualities, it is no matter whether there is such a thing or no, since it no way concerns us; and I do not see the advantage there is in disputing about what we know not what, and we know not why.
We cannot conceive of matter being formed of nothing, since things require a seed to start from... Therefore there is not anything which returns to nothing, but all things return dissolved into their elements.
Pounding fragrant things - particularly garlic, basil, parsley - is a tremendous antidote to depression. But it applies also to juniper berries, coriander seeds and the grilled fruits of the chilli pepper. Pounding these things produces an alteration in one's being - from sighing with fatigue to inhaling with pleasure. The cheering effects of herbs and alliums cannot be too often reiterated. Virgil's appetite was probably improved equally by pounding garlic as by eating it.
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.
