Well, we can take what we know about the
universe
to try and figure that out.
What is at the center of the
universe?
The rest of the
universe
and all of its stars were on the last crystal sphere.
For centuries, this was central to how Europe and the Islamic world saw the
universe.
He believed that the sun was at the center of the
universe.
Eventually, we had to let go of the idea that we were at the center of the
universe.
Shortly after Copernicus, in the 1580s, an Italian friar, Giordano Bruno, suggested the stars were suns that likely had their own planets and that the
universe
was infinite.
Centuries later, the philosopher Rene Descartes proposed that the
universe
was a series of whirlpools, which he called vortices, and that each star was at the center of a whirlpool.
According to this theory, all matter in the
universe
was once a singular, infinitely dense particle.
In a sense, our piece of the
universe
was once at the center.
But this theory eliminates the whole idea of a center since there can't be a center to an infinite
universe.
Scientists have even used pi to prove the illusive notion that light functions as both a particle and an electromagnetic wave, and, perhaps most impressively, to calculate the density of our entire universe, which, by the way, still has infinitely less stuff in it than the total number of digits in pi.
This belief holds that the
universe
has a hierarchy resembling a chain, and that chain starts at the top with God, then travels down through the angels, planets, stars, and all lifeforms before ending with demons and devils.
Because humans have a mortal body accompanied by an immortal soul, we divide the
universe
nicely in half.
Pico claimed that God desired a being capable of comprehending the beautiful and complicated
universe
he had created.
This led to the creation of mankind, which he placed at the center of the
universe
with the ability to take whatever form he pleases.
If geometry is the language the
universe
is written in, then this sketch seems to say we can exist within all its elements.
General relativity is unquestionably Einstein's masterpiece, a theory which reveals the workings of the
universe
at the grandest scales, capturing in one beautiful line of algebra everything from why apples fall from trees to the beginning of time and space.
Over the last century, these two ideas have utterly transformed our understanding of the
universe.
It's thanks to relativity and quantum mechanics that we've learned what the
universe
is made from, how it began and how it continues to evolve.
This is the essential problem: the
universe
is far, far too interesting.
Relativity and quantum mechanics appear to suggest that the
universe
should be a boring place.
But when we look around us, we see we live in a
universe
full of interesting stuff, full of stars, planets, trees, squirrels.
These are properties of the
universe
that we can measure, and they're extremely dangerous because if they were different, even by a tiny bit, then the
universe
as we know it would not exist.
In both of these scenarios, atoms could not exist, and therefore all the other interesting stuff that we see around us in the
universe
would not exist.
If it were a tiny bit different, then there would be no physical structure in the
universe.
But there's actually an even worse example of this kind of fine-tuning of a dangerous number, and this time it comes from the other end of the scale, from studying the
universe
at vast distances.
One of the most important consequences of Einstein's general theory of relativity was the discovery that the
universe
began as a rapid expansion of space and time 13.8 billion years ago, the Big Bang.
Now, according to early versions of the Big Bang theory, the
universe
has been expanding ever since with gravity gradually putting the brakes on that expansion.
But in 1998, astronomers made the stunning discovery that the expansion of the
universe
is actually speeding up.
