The universe’s biggest mystery

Dark matter and dark energy dominate our universe. They’re both highly mysterious, invisible and difficult to detect. So what are they, and how do we know they even exist?

00:00 - What is the universe made of?
01:53 - What is dark matter?
05:32 - What is dark energy?
08:54 - The future of the universe

“Metaphors for ignorance” - my favourite explanation of Dark matter and dark energy

Einstein: That was my greatest blunder.
Everyone Else: Oh that's ok. Everyone is wrong sometimes.
Einstein: Haha. I wasn't wrong. I just didn't understand why I was right.

This is why I love the Economist. This might be the first time I've seen dark matter/energy covered with an immediate mention of the fact that the names 'dark matter' and 'dark energy' are just place holders and do not refer to any matter/energy of confirmed nature. This is something I see lacking in almost every popular science coverage of the topics. Make me very happy!

The idea of looking for matter which is invisible by its effects such as gravitational pull is wonderful. However as a civilization, I feel we are still far from our Eureka moment.

A lot of folks have been going on about a January rally and said stocks that would be experiencing significant growth these new year season, any idea which stocks this may be? I just sold my home in the Boca Grande area and I’m looking to remunerate a lump sum into the stock market before stocks rebound

"Europe's gravitational wave detector is expected to launch in 2037". The craft is called LISA. It's the successor to the test one called LISA Pathfinder that already launched in 2015.
I cannot wait for the age of gravitational wave detectors in space.
