And because this chart looks like the charts that show the expanding universe, with the galaxies flying away from one another, the scientists who discovered it call it "The Big Bang of Body Types."
The
universe
is 13.8 billion years old, give or take.
If we represent the age of the
universe
by one year, then our species came into being about 12 minutes before midnight, 31st December.
It's about understanding our place in the
universe.
One planet in a trillion galaxies, just as in the visible
universe.
A
universe
that's silent because technology itself forms the barrier to the development of a truly advanced civilization.
But for me, the silence of the
universe
is shouting, "We're the creatures who got lucky."
And if we learn to appreciate how special our planet is, how important it is to look after our home and to find others, how incredibly fortunate we all are simply to be aware of the universe, humanity might survive for a while.
This is a picture of the Ptolemaic
universe
with the Earth at the center of the
universe
and the sun and the planets going around it.
So when Nicolaus Copernicus said, actually the Earth is not the center of the universe, the sun is the center of the solar system, the Earth moves around the sun.
But at the same time, it's the most mysterious phenomenon in the
universe.
Physicists sometimes take some aspects of the
universe
as fundamental building blocks: space and time and mass.
Understanding consciousness is a real key, I think, both to understanding the
universe
and to understanding ourselves.
It is five billion years before the sun flares up, and the
universe
may go on forever, so post-human evolution, here on Earth and far beyond, could be as prolonged as the Darwinian process that's led to us, and even more wonderful.
So astronomy is constantly being transformed by this capacity to collect data, and with data almost doubling every year, within the next two decades, me may even reach the point for the first time in history where we've discovered the majority of the galaxies within the
universe.
But as we enter this era of big data, what we're beginning to find is there's a difference between more data being just better and more data being different, capable of changing the questions we want to ask, and this difference is not about how much data we collect, it's whether those data open new windows into our universe, whether they change the way we view the sky.
So what is the next window into our
universe?
Well, I'm going to show you some of the tools and the technologies that we're going to develop over the next decade, and how these technologies, together with the smart use of data, may once again transform astronomy by opening up a window into our universe, the window of time.
About the evolution of our
universe.
Why our
universe
is continuing to expand, and what is this mysterious dark energy that drives that expansion?
but it's also a static view, and in many ways, this is the way we think of our universe: eternal and unchanging.
But the
universe
is anything but static.
Ten supernova per second explode somewhere in our
universe.
This swarm of objects you see streaming across the sky are asteroids as they orbit our sun, and it's these changes and the motion and it's the dynamics of the system that allow us to build our models for our universe, to predict its future and to explain its past.
The Hubble Space Telescope: for the last 25 years it's been producing some of the most detailed views of our distant universe, but if you tried to use the Hubble to create an image of the sky, it would take 13 million individual images, about 120 years to do this just once.
So this is driving us to new technologies and new telescopes, telescopes that can go faint to look at the distant
universe
but also telescopes that can go wide to capture the sky as rapidly as possible, telescopes like the Large Synoptic Survey Telescope, or the LSST, possibly the most boring name ever for one of the most fascinating experiments in the history of astronomy, in fact proof, if you should need it, that you should never allow a scientist or an engineer to name anything, not even your children.
I'm going to show you how we think it's going to transform our views of the universe, because one image from the LSST is equivalent to 3,000 images from the Hubble Space Telescope, each image three and a half degrees on the sky, seven times the width of the full moon.
Over the mission lifetime of this telescope, it will detect 40 billion stars and galaxies, and that will be for the first time we'll have detected more objects in our
universe
than people on the Earth.
Now, distance and changes in our
universe
— distance equates to time, as well as changes on the sky.
Every foot of distance you look away, or every foot of distance an object is away, you're looking back about a billionth of a second in time, and this idea or this notion of looking back in time has revolutionized our ideas about the universe, not once but multiple times.
