Let's talk about building wealth. What do I mean by that? I mean no longer living paycheck to paycheck. I mean choosing what jobs you say yes/no to. I mean building your dream lifestyle—where you eat, how you dress, where you go on vacation. And if you're sitting there thinking like, “Oh, yeah right. Not in the theater industry.” Think again! Becau…

There's another claim for a violation of the cosmological principle - that all parts of the universe are basically the same on large scales - but Top quark Jim Cooney explains all is not lost for the standard model of the universe, and more observations are needed. The JWST is providing amazing observations near and far, and has now separately meas…

Congratulations! You've landed your dream job! But what's the offer? It's now time to negotiate the contract. Most people make the mistake of only focusing on the money, so they're missing out on a ton of other things they could be negotiating. Likewise, if the pay is non-negotiable, you may think you just have to accept the contract as is. But tha…

In today's episode, we brace ourselves with a powerful quote: "Imperfect action is better than taking perfect inaction." This episode is centered on taking action—acting before we feel completely prepared or when fear threatens to paralyze our progress. Growth demands that we step outside our comfort zone, requiring action even when fear tries to r…

What role has Jupiter played in the existence of our warm and cosy home planet? Has it been bravely using its gravity to keep the inner solar system calm, or did we luck out and escape getting hurtled out of the solar system or dashed to bits in a giant collision? We’ll discuss new research that explores exoplanetary systems with multiple large pla…

We've all been brainwashed into thinking that all we need to do to book our dream jobs is to keep improving our talent and skills. So we spend hour after hour, training and training, going to class after class. That’s what we’ve been told to focus on. Even though there is all this evidence around us that contradicts that, we don't even question it.…

At Pluto’s frigid temperatures, even what we breathe is frozen. This can give rise to unusual cryovolcanism, and new research suggests a super cryovolcano tens of kilometers across on the ninth planet (yes, we went there). Speaking of super things, we also review the argument that we are located in a cosmological supervoid and whether than can expl…

Networking. Just the sound of that word probably makes you feel gross inside. Does anyone really want to go to a cocktail party where the drinks are overpriced and you're in a room full of people all talking about how wonderful they are? Or where everyone is trying to talk to “the cool kids” at the top of the social ladder and trying to get a job f…

As Thanksgiving week rolls around here in the United States, we're all aware that people have various feelings and thoughts about this holiday and what we’re actually celebrating. But for the purpose of this week’s episode, let’s not attach any specific meaning or significance to the day. Instead, let's focus on the word itself. Thanksgiving = givi…

JWST data confirm early formation of supermassive black holes, less than 500 million years after the big bang. This early formation suggests these monsters start off very large and form with the initial formation of the galaxy. We also take a closer look at the exciting results from the Lucy spacecraft's flyby of the asteroid Dinkinesh and its surp…

The Lucy spacecraft had its first asteroid encounter, revealing Dinkinesh to be a binary asteroid. In cosmology, a new simulation with a terrible acronym leaves the "S8 Tension" intact. Models of the expansion of the universe starting with our observations of the cosmic microwave background are in disagreement (tension) with observations of the act…

Do you feel like there's not enough time in the day? Or that you have too many things to get done and too short of time? Or wish you just had a few more hours to get everything done on your to-do list? I bet you do, because anytime I ask artists what’s the number one thing they're struggling with, it's always time. And it makes sense because in a b…

New research suggests that Venus, Earth’s twin gone bad, may have started off with tectonic plate activity, like Earth. This will help us understand the evolution of Earth-like planets and why they become hothouses like Venus. Our other planetary next-door neighbor, Mars, may have a deep molten magma ocean, revealed thanks to a fortuitous meteoroid…
