The whole thing is held together by entities which we don’t know exist at all and they have no real physical basis. Professor Mike Disney
I am really not impressed with the amount of fine tuning there is, with the exception of this one – dark energy. Professor Steven Weinberg, interview Professor Richard Dawkins
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 theorist’ extraordinary conclusion was that this unknown energy came from the very vacuum of space. Horizon: From Here to Infinity, BBC 1999
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. Horizon: Most of our Universe is Missing, BBC 2006
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.
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. ibid.
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? Horizon: Is Everything We Know About the Universe Wrong? BBC 2010
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. ibid.
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. ibid.
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. ibid.
The explosion hasn’t stopped. The Big Bang is still banging. ibid.
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. ibid.
Dark matters outweighs it six to one. Horizon: How Big is the Universe? BBC 2012
Cosmologists don’t know what Dark Energy is, they only know what it does. ibid.
Dark Matter is fighting a losing battle. ibid.
The entire observable universe is saturated in Dark Energy. ibid.
72,693. Dark Energy ... it makes up most of the universe. Horizon: Dancing in the Dark – The End of Physics, BBC 2015
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
A hundred years after Einstein’s biggest Einstein’s blunder, the Cosmological Constant is back … to account for its unexplained accelerating expansion. ibid.
Saul’s team had discovered a totally unexpected and unexplained repulsion between galaxies that is gradually blowing the universe apart: they called it Dark Energy ... It makes up nearly three quarters of the universe. Dark Energy rules the universe. Morgan Freeman’s Through the Wormhole s1e8: Beyond the Darkness, Science 2013
Dark Energy: an inexplicable force that is trying to push everything apart. How will this struggle end? ibid.
Eternal Inflation + Dark Energy + String Theory = We may live in a multiverse. Professor Brian Greene, Beyond the Cosmos: Multiverse, National Geographic 2012
In our picture, there was a universe before the Big Bang, very much like our universe today: a low density of matter and some stuff called dark energy. If you postulate a universe like this, but the dark energy within is actually unstable, then the decay of this dark energy drives the two branes together. These two branes clash and then, having filled with radiation, separate and expand to form galaxies and stars.
Then the dark energy takes over again. It’s the energy of attraction between the two branes: It pulls them back together. You have bang followed by bang followed by bang. You have no beginning of time. It’s always been there. Neil Turok
Dark Energy is going to kill galaxies off. Professor Lawrence Krauss
We have no idea what Dark Energy is. Dark Energy is basically a fancy word for our ignorance of what makes up 75% of our universe. Professor Max Tegmark, MIT
Dark energy is the energy of the vacuum. The energy of nothing. Even nothingness has energy and it’s pushing the galaxies apart in a runaway universe ... So it looks like the end of everything. Professor Michio Kaku
Our universe is not slowing down as we once thought but is speeding up, is accelerating. It’s in a runaway mode. We now believe there is something called Dark Energy – the energy of nothing – that is pushing the galaxies apart and is destroying the universe. Michio Kaku
Dark Matter and Dark Energy combined make up 96% of the universe ... Dark Matter’s invisible presence appears to be everywhere. But Science has not directly proven Dark Matter particles exist. There are many theories but no answers. And observing something you can’t see isn’t easy. The Universe s2e6: Dark Matter/Dark Energy, History 2007
It’s estimated Dark Matter makes up 23% of the universe. While ordinary matter makes up only 4%. But what makes up the final 73% of the universe? Scientists have proposed that a new mysterious Dark Energy is dominating space, and its repulsive energy is driving the galaxies apart ... Scientists were shocked to realise that its growth wasn’t slowing down: it was speeding up. This implied a bleak future. ibid.
Dark Energy was first observed in 1998 when measurements of far-away exploding stars were used to determine the distances of galaxies. Those galaxies were found to be further away than expected in a universe that’s slowing down with time. The astronomers therefore concluded that the universe is actually expanding more quickly with time, and Dark Energy may be the culprit. The Universe s3e10: Strangest Things, History 2009
Dark Energy has the opposite effect of Dark Matter. Instead of binding galaxies together it pushes them apart. How the Universe Works s1e3: Galaxies, Discovery 2010
In the 1970s astronomers were completely stunned … the galaxies were spinning too fast, far too fast … nine-tenths of their mass was missing … they called it dark matter … Astronomers have mapped out the distribution of dark matter using gravitational lensing … Dark matter fills the universe. How the Universe Works s3e2: The End of the Universe
The acceleration baffled the scientists … The new energy seemed to be coming from nothing … dark energy. ibid.
The universe will end in one of two ways: the Big Rip or the Big Freeze. ibid.
So when did dark energy begin to control the universe? ibid.
As space expanded, dark energy increased in comparison with it. ibid.
The universe is heading for a Big Freeze. ibid.
Across the universe an endless war rages. A bitter struggle between invisible forces. Dark matter and dark energy. Battling for control of the universe. Shadowy forces dictating our past, our present and our future. How the Universe Works s7e7: Battle of the Dark Universe
What we see is just a small part of the cosmos. The rest is invisible, unknown. A dark universe. ibid.
‘Dark matter is attractive, dark energy is repulsive.’ ibid. scientist
There’s a bigger unsolved mystery than Dark Matter – Dark Energy. Neil deGrasse Tyson, Cosmos: A Spacetime Odyssey: Unafraid of the Dark XIII, National Geographic 2014
