Quotes About Dark Matter

Christopher Savage have calculated that in reasonable models, we expect about ten dark-matter particles to interact with the atoms in a typical human body every year. The effects of every individual interaction are pretty negligible, so don't worry about getting a dark matter stomachache.

Dark matter is needed to hold galaxies together. Your mind is a Galaxy. More dark than light. But the light makes it worthwhile.

I wish life could be edited as deftly as prose. It would be nice to go back and write a better story, correcting weaknesses and follies in the light of what I now know. What I've noticed though is that any attempt to trim out the dark matter takes away some of the good that was also buried in the muck. The past is a package deal and I don't believe there's a way to tell some of the truth without telling most.Wisdom comes at a price, and I have paid dearly for mine.

Isn't the universe full of gaseous elements?" Andrew says, "Yeah, there are gases and neutrinos and this shit they call dark matter.

appears that at least 90 percent of the universe, and perhaps as much as 99 percent, is composed of Fritz Zwicky's "dark matter"—stuff that is by its nature invisible to us.

two-thirds of the universe is still missing from the balance sheet

It appears that the universe may not only be filled with dark matter, but with dark energy.

WIMPs (for Weakly Interacting Massive Particles, which is to say specks of invisible matter left over from the Big

Since photographs of galaxies only show the beautiful swirling mass of stars, whatever is holding the mass together must not interact with light—it must be invisible.

Since the familiar particles and the objects they compose—stars, planets, people, etc.—amount to less than 5 percent of the mass of the universe, such a disruption would not affect the vast majority of the universe, at least as measured by mass.

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 missing link in cosmology is the nature of dark matter and dark energy.

Dark matter is a mysterious substance that has gravity but does not interact with light in any known way.

The most accurate measurements to date reveal dark energy as the most prominent thing in town, currently responsible for 68 percent of all the mass-energy in the universe; dark matter comprises 27 percent, with regular matter comprising a mere 5 percent.

That is, cosmic dark matter enjoys about six times the mass of all the visible matter.

Ordinary matter is what we are all made of. It has gravity and interacts with light. Dark matter is a mysterious substance that has gravity but does not interact with light in any known way. Dark energy is a mysterious pressure in the vacuum of space that acts in the opposite direction of gravity, forcing the universe to expand faster than it otherwise would.

Ordinary matter is what we are all made of. It has gravity and interacts with light. Dark matter is a mysterious substance that has gravity but does not interact with light in any known way. Dark energy is a mysterious pressure in the vacuum of space that acts in the

From galaxy to galaxy and from cluster to cluster, the discrepancy between the mass tallied from visible objects and the objects' mass estimated from total gravity ranges from a factor of a few up to (in some cases) a factor of many hundreds. Across the universe, the discrepancy averages to a factor of six: cosmic dark matter has about six times the total gravity of all the visible matter.

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.

So dark matter is our frenemy. We have no clue what it is. It's kind of annoying. But we desperately need it in our calculations to arrive at an accurate description of the universe. Scientists are generally uncomfortable whenever we must base our calculations on concepts we don't understand, but we'll do it if we have to. And dark matter is not our first rodeo.

As we've known from the beginning, dark matter does, indeed, exert gravity, to which ordinary matter responds. But that's it. After all these years, we haven't discovered it doing anything else.

It may be that DMT makes us able to perceive what the physicist call "dark matter" - the 95 per cent of the universe's mass that is known to exist but that at present remains invisible to our senses and instruments.

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

Physicists now know that 70 per cent of the known universe is dark energy. Dark matter is another 25 per cent. Once we thought we knew all about life, but it turns out everything we think of as reality is less than 5 per cent.
