NASA’s Hubble Space Telescope discovered these electrically charged molecules shaped like soccer balls. These «buckyballs» could shed insight on the creation of stars and planets.

The power of Dark Energy may be increasing as the universe ages. Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent episode on the Crisis in Cosmology. Today we’re doing a Space […]

What about dark energy allows it to resist the powerful inward pull of gravity and accelerate the rate of the universe’s expansion? Find out in this episode of Space Time. And watch our previous episodes on dark energy right here: Part 1 – Will the Universe Expand Forever https://www.youtube.com/watch?v=xZTb6… Part 2 – Why the Universe […]

How physics lets us rewind time to the beginning of the universe.

The only visual record of the historic Apollo 11 landing is from a 16mm time-lapse (6 frames per second) movie camera mounted in Buzz Aldrin’s window (right side of Lunar Module Eagle or LM). Due to the small size of the LM windows and the angle at which the movie camera was mounted, what mission […]

Electric vehicles, rockets… and now brain-computer interfaces. Elon Musk’s newest venture, Neuralink, aims to bridge the gap between humans and artificial intelligence by implanting tiny chips that can link up to the brain. At a press conference on July 16, Neuralink’s ambitious plans were detailed for the first time, showcasing a future (a very distant […]

This is Ikea’s future lab, Space10. It’s a space in downtown Copenhagen where researchers are creating a sustainable future by changing the way we live, work, and eat. 

Jeff Bezos wants to colonize space. But he knows there’s a lot of work to be done before that’s possible. First we need cheap, reusable rockets. Then we need to mine resources on the Moon. It’s generations of work, but Bezos says he’s up for the challenge.

As more and more fossil ancestors have been found, our genus has become more and more inclusive, incorporating more members that look less like us, Homo sapiens. By getting to know these other hominins–the ones who came before us–we can start to answer some big questions about what it essentially means to be human.

We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

If space is a vacuum, is it possible to hear sound in it? Trace is here to discuss why sound travels differently in space.
