Useful as the
universe'
s most massive laboratories.
They are essentially isolated systems, so if we like, we can think of them as a scaled-down version of the entire
universe.
And many of the questions that we might have about the
universe
at large scales, such as, how does gravity work?
Most of the
universe'
s matter is not made up of atoms.
Since galaxy clusters are representative slices of the universe, scaled-down versions.
Similarly, cosmologists understand why the
universe
is expanding.
So, one particular question that we have is, how does dark energy affect the
universe
at the largest scales?
Well, the problem with the large-scale structure of the
universe
is that it's horribly complicated.
Similarly, I can learn a lot about the
universe
at the largest scales by tracking its biggest pieces and those biggest pieces are clusters of galaxies.
And I can't think of a better way to do this than by studying the
universe
around us.
And the laws of these particles are valid throughout the universe, and they're very much connected with the history of the
universe.
So what that means is that the history of the
universe
is not determined just by the fundamental law.
And in fact, a huge amount of the information in the
universe
around us comes from those accidents, and not just from the fundamental laws.
Now this is the key part, and again it doesn't have to be you, because you can get creative, because there is a whole
universe
out there of nominees to choose from.
And having the goal in mind, thinking about where it might lead, directed me to a life of looking at all of the small details to allow this to become possible, to be able to launch and go help build a space station where you are on board a million-pound creation that's going around the world at five miles a second, eight kilometers a second, around the world 16 times a day, with experiments on board that are teaching us what the substance of the
universe
is made of and running 200 experiments inside.
It's an entirely different perspective, you're not looking up at the universe, you and the Earth are going through the
universe
together.
I know this song, and it's really a tribute to the genius of David Bowie himself, but it's also, I think, a reflection of the fact that we are not machines exploring the universe, we are people, and we're taking that ability to adapt and that ability to understand and the ability to take our own self-perception into a new place.
Now, the Big Bang was an era in the early
universe
when everything we see in the night sky was condensed into an incredibly small, incredibly hot, incredibly roiling mass, and from it sprung everything we see.
And those small, little, inhomogeneities, 20 parts in a million, those were formed by quantum mechanical wiggles in that early
universe
that were stretched across the size of the entire cosmos.
Now, that early
universe
was incredibly dense, like a metal, way denser, and if you hit it, it would ring, but the thing ringing would be the structure of space-time itself, and the hammer would be quantum mechanics.
What they found on Monday was evidence of the ringing of the space-time of the early universe, what we call gravitational waves from the fundamental era, and here's how they found it.
But early on, when the
universe
was making that last afterglow, the gravitational waves put little twists in the structure of the light that we see.
The thing that's totally amazing, the reason I'm on this stage, is because what that tells us is something deep about the early
universe.
We're never going to see the stuff outside, but by going to the South Pole and spending three years looking at the detailed structure of the night sky, we can figure out that we're probably in a
universe
that looks kind of like that.
Knowing that there's so much around us we can't see forever changes our understanding of the world, and by looking at unseen worlds, we recognize that we exist in the living universe, and this new perspective creates wonder and inspires us to become explorers in our own backyards.
How is it that we are all now navigating a child-rearing
universe
without any norms to guide us?
The
universe
is teeming with planets.
The sun and all the stars in the
universe
run on fusion.
Temperatures this low give scientists a window into the inner workings of matter, and allow engineers to build incredibly sensitive instruments that tell us more about everything from our exact position on the planet to what’s happening in the farthest reaches of the
universe.
So as researchers continue in their quest to understand the laws of physics and unravel the mysteries of the universe, they’ll do so with the help of the very coldest atoms in it.
