Seeker explains how a new kind of nuclear battery could power missions into deep space.

In April of 2020, NASA researchers announced they had come up with a new approach to fusion that has the potential to power missions into deep space, and maybe even future laptops here on Earth. This is really exciting news as when it comes to making energy, nuclear fusion is the ultimate goal because of the promise it holds of clean limitless energy that is available on demand.

In this episode, Seeker tackles the question that’s on everyone’s minds: what will it take to have quantum internet in our home?

Yes, Virginia, a quantum internet is in the works.

The U.S. Department of Energy recently rolled out a blueprint describing research goals and engineering barriers on the way to quantum internet.

The DOE’s latest blueprint for a quantum internet in the U.S. has four key milestones. The first is to make sure quantum information sent over current fiber optic cables is secure. Then to establish entangled networks across colleges or cities, then throughout states, and finally for the whole country.

In this video, Sabine Hossenfelder explains how public key cryptography works on the internet today, using RSA as example, what the risk is that quantum computers pose for internet security, what post-quantum cryptography is, how quantum key distribution works, and what quantum cryptography is.

Artificial sentience straddles the fields of philosophy and engineering.

Throw robots into the mix and it gets really interesting.

Seeker examines what it mean for a robot to be self-aware.

The Creative Machines Lab at Columbia University“At the Creative Machines Lab we build robots that do what you’d least expect robots to do: Self replicate, self-reflect, ask questions, and even be creative. We develop machines that can design and make other machines – automatically.”

Seeker examines how research into quantum computing may uncover more about the universe.

Scientists have built an advanced instrument with parts from a quantum computer that’s sensitive enough to listen for the signal of a dark matter particle. The Axion Dark Matter Experiment (ADMX) at the University of Washington is the world’s first dark matter experiment that’s hunting specifically for axions.
