2,670. Scientists talk about dark matter, the invisible, mysterious substance that occupies the space between stars. Dark matter makes up 99.99 percent of the universe, and they don't know what it is. Well I do. It’s apathy. That’s the truth of it; pile together everything we know and care about in the universe and it will still be nothing more than a tiny speck in the middle of a vast black ocean of Who Gives a Fuck. (Science & Universe & Apathy & Cosmology & Astronomy & Dark Matter) David Wong, John Dies at the End
2,722. The whole thing is held together by entities which we don’t know exist at all and they have no real physical basis. (Universe & Dark Matter & Cosmology & Astronomy) Professor Mike Disney
2,756. I am really not impressed with the amount of fine tuning there is, with the exception of this one – dark energy. (Universe & Cosmology & Dark Energy & Anthropic Principle) Professor Steven Weinberg, interview Professor Richard Dawkins
2,789. It is in these clumps of dark matter that galaxies like the Milky Way would have formed ... The dark matter is the skeleton of the universe. (Universe & Dark Matter & Galaxy & Astronomy) Carlos Frenk
69,306. When Dark Matter is discovered I think the whole jigsaw of our universe will fall into place. Professor Carlos Frenk, Durham University
69,309. Hot dark matter makes the clusters of galaxies far too big to match the observable universe. It was bad news. The other alternatives weren’t as attractive as the already observed neutrinos. So if hot dark matter wasn’t the answer, what was? 1984 was the year of cold dark matter. Horizon: Of Big Bangs, Stick Men and Galactic Holes, BBC 1991
2,802. There had to be some unknown and mysterious energy out there in the cosmos pushing everything apart, fighting against Gravity. What could this powerful energy be? Why had it never been seen before? What generates it, and where was it hiding? The theorists’ extraordinary conclusion was that this unknown energy came from the very vacuum of space. (Universe & Cosmology & Laws & Gravity & Space & Dark Energy) Horizon: From Here to Infinity, BBC 1999
2,803. There’s something weird out there in the universe ... Something we can’t see is pulling the strings of the universe. The alien stuff, if it exists, needs to fill a very big hole because 96% of our universe is unaccounted for. (Universe & Cosmology & Astronomy & Dark Matter) Horizon: Most of our Universe is Missing, BBC 2006
69,310. [Fritz] Zwicky was a difficult man to get along with. So his scientific work had sometimes been overlooked. But his forgotten ideas about Dark Matter were a godsend for Ostriker and Peebles. ibid.
2,804. Science had uncovered a puzzle. There was something missing. There wasn’t enough mass in the universe to provide the gravity to hold it together. And yet there the universe was - obviously not falling apart. But science had also provided an answer. Peebles and Ostriker’s Dark Matter made everything work. And thanks to Vera [Rubin] it was suddenly very popular. (Universe & Cosmology & Astronomy & Dark Matter & Gravity) ibid.
69,311. Dark Matter was headline news. There was only one small problem – no-one had actually found any Dark Matter. ibid.
69,312. The gas was orbiting just as fast as the stars. Even the hydrogen gas was being manipulated by a mysterious force. It seemed that Dark Matter would have to exist as a huge all-pervading halo surrounding a galaxy and everything in it including us here on Earth. All the evidence pointed towards one slightly unsettling thing: Dark Matter is not made of atoms like us and everything we know. ibid.
69,313. The amount of energy needed to cause the acceleration was hugely significant. Because energy is proportional to mass it accounted exactly for the missing 75% of the universe. ibid.
2,805. Finally none of the universe was missing. It was made of 4% atoms, the stuff we’re familiar with, 21% Dark Matter that no-one could find, and a whopping 75% made from brand-new whizzy Dark Energy that nobody could understand. Cosmology’s standard model was born. (Universe & Cosmology & Astronomy & Dark Matter) ibid.
2,808. A new generation of Cosmologists are questioning our basic understanding of the universe. They are beginning to wonder if there is a greater reality. Could it be that everything we think we know about our universe is wrong? (Universe & Cosmology & Reality & Dark Matter) Horizon: Is Everything We Know About the Universe Wrong? BBC 2010
2,809. Somewhere out in the universe there seems to be a disturbing force that we can’t explain. A force of astonishing power that appears to have bent trillions of stars to its will. Gripping not just galaxies but whole clusters of galaxies spanning billions of light years’ of space. And it’s dragging everything to a single point. This mysterious phenomenon is known as Dark Flow. And it shouldn’t be happening. (Universe & Cosmology & Dark Matter) ibid.
2,810. For all its intricate mathematics the standard model has flaws. Built into it are a series of theories designed to explain observations that don’t make any sense. Theories that are incomplete and unproven. (Universe & Cosmology & Dark Matter & Theory & Mathematics) ibid.
2,811. Big Bang theory says that the universe was created in an explosion. But an explosion would produce a universe that was lumpy and messy. With patches there were at vastly different temperatures from one area to another. The real universe is nothing like this. In all directions the temperature appears to be almost exactly the same. (Universe & Cosmology & Dark Matter & Theory & Mathematics & Big Bang) ibid.
2,812. The explosion hasn’t stopped. The Big Bang is still banging. (Universe & Cosmology & Dark Matter & Big Bang) ibid.
2,813. Guth thinks our universe is part of a bigger structure; we’re in a small piece of it. A bubble created by Inflation. It could mean that Dark Flow is evidence our universe is not alone. (Universe & Cosmology & Dark Matter & Big Bang & Multiverse) ibid.
2,823. Dark matters outweighs it six to one. (Universe & Cosmology & Astronomy & Dark Matter) Horizon: How Big is the Universe? BBC 2012
2,828. Cosmologists don’t know what Dark Energy is, they only know what it does. When gravity pulls, Dark Energy pushes. (Universe & Cosmology & Astronomy & Gravity & Dark Energy) ibid.
2,829. Dark Matter is fighting a losing battle. (Universe & Cosmology & Astronomy & Gravity & Dark Energy) ibid.
2,830. The entire observable universe is saturated in Dark Energy. (Universe & Cosmology & Astronomy & Gravity & Dark Energy) ibid.
72,687. Nowadays our understanding of the birth of the universe is extremely detailed. Horizon: Dancing in the Dark - The End of Physics, BBC 2015
72,688. These theoretical Dark Matter candidates are called WIMPS. ibid.
72,689. The hunt for Dark Matter has so far proved to be the world’s most least productive experiments. ibid.
72,690. We’re looking for a new particle. (Dark Matter & Particle) ibid.
72,691. The LHC has been switched off for two years while it’s been upgraded ... twice the energy it did before. (Dark Matter & Particle Accelerator) ibid.
72,692. There are other cold dark matter candidates. ibid.
72,693. Dark Energy ... it makes up most of the universe. ibid.
86,756. The universe is falling apart. Something is forcing galaxies to rush away from each other at ever increasing speeds. Ever since this alarming discovery physicists have struggled to understand what might be causing it. So far they’ve come up with a name – they’ve called it Dark Energy. Horizon: The Mystery of Dark Energy, BBC 2016
72,020. A hundred years after Einstein’s biggest blunder, the Cosmological Constant is back … to account for its unexplained accelerating expansion. ibid.
