Our world, our solar system, our universe, none of it would exist without a ghostly particle called the neutrino. They are our early warning system whenever there's trouble in the universe. Neutrinos trigger star-killing explosions, supernovas. Neutrinos can answer so many questions, from why do we exist to how was the universe created. Neutrinos can be the very reason that we exist at all. The more we understand these elusive particles, the more we can gain insight into how the universe works.

Experts explore the elusive endeavor of determining the age of the cosmos. Understanding the age of the universe is fundamental to understanding the universe at all. It's at the heart of everything. We want to know how much mass is in it, how much energy is in it, how it behaves. We have to have this number nailed down. The age of the universe enables us to not only understand where we came from, but potentially, the fate of the universe, what will happen millions and billions of years from now.
The idea that the universe grew from a ball smaller than a pinhead is hard to understand, but figuring out when it happened sounds like it should be more straightforward. But it turns out, getting the age of the universe is pretty tricky.

There's evidence that dark matter makes up 85% of all the matter in the universe. We can see dark matter holding galaxies together and ripping other structures apart, we even see it bending light. Dark matter itself has been around since the beginning of the universe. Without dark matter, we wouldn't be here. But if you can't see dark matter and if you can't touch it, does it really exist?
Dark Matter is thought to be the cosmic glue that holds the universe together, yet the search for it continues to eluded scientists today.
