Sure, there are some less than savory elements in there,

but on the whole, scholars agree that its existence

of scientific endeavor is devoted to its study.

Cosmologists look at what's out there in space

and piece together the tale of how our universe evolved:

by noting that galaxies seem to be flying

This implied that everything should have started

This idea was jokingly referred to at the time

to form the stars and galaxies that we see today.

But we can also probe the origins of the universe

by recreating the hot, dense conditions that existed

at the beginning of time in the laboratory.

matter and forces at higher and higher energies.

the further back in time they can effectively peek.

Today, things are largely made up of atoms,

but a hundreds of seconds after the Big Bang,

that usually hold protons and neutrons together

Further back, microseconds after the Big Bang,

and the protons and neutrons were only just beginning

of the standard model of particle physics.

Physicists hope that by going to even greater energies,

when all the forces were one in the same,

the origins of the universe a lot easier.

To do that, they'll not only need to build bigger colliders,

but also work hard to combine our knowledge
