Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what’s all this nonsense of extra dimensions?

Most people are taught that dinosaurs went extinct 66 million years ago when a giant meteor crashed into the Yucatan peninsula. I’m here to tell you that’s wrong. Dinosaurs are alive and well today, and you don’t have to go to Jurassic World to see them (although hanging out with Chris Pratt would be cool).

The average American will move households 11 times over the course of their life. It can be stressful and exhausting, but it doesn't have to be expensive!

When Quasars were first discovered the amount of light pouring out of such a tiny dot in space seemed impossible. A hysterical flurry of hypothesizing followed: swarms of neutron stars, alien civilizations harnessing their entire galaxy’s power, bright, fast-moving objects being ejected by our own galaxy’s core.

What happens when matter can’t get any denser yet somehow does? The answer - it becomes strange. Strange Stars may be the most massive stellar remnant that is just shy of forming a black hole. And they could be even cooler than black holes.

The private space-race has been on for a while now. The attention has been on Space-X and Blue Origin with their reusable rockets. But there’s one private space program that’s been doing things a little differently. Richard Branson’s Virgin Galactic isn’t building rockets at all – it’s building spaceships. And I got to sit down and talk to him about it.

What really crashed down to Earth in Roswell, New Mexico in 1947? Can we trust the government when they say it was just a weather balloon? Today Danielle looks at the history of alien conspiracies and what they teach us about the legacy of modern warfare, globalization, distrust of the government, and paranoia about foreign invaders.

Is more choice really better than less?

It’s been conjectured that the center of the Milky Way is swarming with tens of thousands of black holes. And now we’ve actually seen them.

We can now map the interiors of stars by “listening” to their harmonies as they vibrate with seismic waves.

Astronomers are the worst at naming things. Dark energy AND dark matter? Who can remember which is which. But perhaps one astronomer has just fixed it, with a theory that says perhaps actually they are they same stuff.

Day by day, country by country, we tend to measure seasons differently.

We pretty much know for sure that the universe was once extremely small, and extremely hot. And we know that something set it in motion, expanding rapidly and continuing to do-so today. But the actual moment of ‘the Big Bang’ is still a bit of a grey area within physics.

This episode of Space Time is actually about Spacetime, so pull up a chair, grab your favorite snack, and buckle up, because this episode is going to be a TRIP. Gabe explores what reality is, what "time" is, and why what you think those things are is probably WRONG. Seriously, get ready to have your MIND BLOWN!

There’s this idea that beauty is a powerful guide to truth in the mathematics of physical theory. String theory is certainly beautiful in the eyes of many physicists. Beautiful enough to pursue even if it’s wrong?

Let’s talk about the mysterious zero-point energy and what it really can, and really can’t do.

For the past 90 years, the predictions laid out Einstein's general theory of relativity have continued to be confirmed by experimental science. The last hold out is gravitational waves - the idea that certain gravitational events cause actual ripples in Spacetime. But have scientists done it?

Primordial black holes may be lurking throughout our universe. How large are they, how many are out there and what would happen if they moved through our solar system?

Colour persuasion plays a big role in everyday life...and advertisements.

The flu might feel like some minor illness that you don’t need to worry about much, but tens of thousands of people still die from it every year. And back in 1918, Flu killed up to 5% of the world’s population. Could a flu that bad happen again?

We've got two perfectly good hands attached to two perfectly good arms, so why do most people prefer to use one over the other for common tasks?

You’ve probably known OF E=mc² since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines. BUT WAIT. Was E=mc² explained to you properly? Mass equalling energy is mostly true, but E=mc² actually describes a much more interesting aspect of reality.

We’ll soon be capable of building self-replicating robots. This will not only change humanity’s future but reshape the galaxy as we know it.

On September 14th, 2015 LIGO announced the first detection of a gravitational wave. This was hailed at the time as the dawn of gravitational wave astronomy. However that’s only true if the we ever detect another gravitational wave. Now we have. On December 26th LIGO again observed the merger of two different black holes.

The foundations of quantum theory rests on its symmetries. For example, it should be impossible to distinguish our universe from one that is that is the perfect mirror opposite in charge, handedness, and the direction of time. But one by one these symmetries were found to be broken, threatening to break all of physics along with them.
