Astronomers Now Think Sagittarius A* Isn't What We Assumed

Hey guys! We’re now live on Spotify 🎧 Almost every deep image from the James Webb Space Telescope hides the same strange thing. A tiny red dot. 1 pixel wide. Shining as bright as an entire galaxy. These dots come from the first 1.5 billion years of the universe. They are everywhere. For 3 years, astronomers have argued about what they are. First, they looked like giant galaxies, far too big for their age. Then they looked like hungry black holes. But those black holes stayed quiet. Almost no X-rays. Almost no flicker. Now a bold new theory has split the field down the middle. What if each dot is a single, swollen star, stretching far past the orbit of Pluto, with a black hole burning at its heart? We will visit an object called The Cliff, which defeated every model scientists tried. We will weigh a hidden black hole through a natural magnifying glass made of galaxies. And we will follow the red dots as they seem to vanish from the universe. If you want to watch or listen

Hey guys! We’re now live on Spotify 🎧 Title: Why a Return Trip From Mercury Might Be Physically Impossible Inspired by: You leave Mercury. But can you ever come home? Scientists are not sure you can. Mercury sits so close to the sun that gravity there works like a trap, not a ladder. Reaching this world already takes more fuel than a trip to Jupiter. Leaving it could take even more. In this series, we uncover the real physics that make Mercury a one way risk. We look at the sun's crushing gravity well, the heat that can melt metal, and the fuel math that breaks every plan. We follow the spacecraft that barely survived getting close. And we ask the biggest question of all. Could a human crew ever fly home from Mercury? Prepare yourselves. This is the planet that might not let you leave. Before we start, scan the QR code on your screen, or tap the link in the description. That takes you straight to our show on Spotify.

Hey guys! We’re now live on Spotify 🎧 Pluto sits about 3.7 billion miles from the Sun. The fastest spacecraft we ever launched needed 9 and a half years to get there. And it never stopped. It flew past at more than 30,000 miles per hour. It snapped its photos. Then it was gone. So what happens if you want to go there, land, and come back home? The answer is brutal. With the rockets we have today, the cheapest road takes about 45 years. One way. Tonight, we build that trip piece by piece. We will swing past Jupiter for a free push. We will pack food, water, and air for a journey longer than most careers. We will face invisible radiation, a Sun that shrinks into a bright star, and a frozen world near 400 degrees below zero Fahrenheit. Then we will try to come home. 🎧 Our videos are on Spotify too.

Hey guys! We’re now live on Spotify 🎧 Deep under the border of France and Switzerland, a machine built by thousands of scientists just found a crack in the laws of physics. For fifty years, one theory explained almost everything about matter. Scientists call it the Standard Model. It predicts how particles move, how they decay, and how the universe holds itself together. Now, inside CERN's Large Hadron Collider, a new measurement breaks that pattern. Certain particles are decaying in a way the Standard Model says should not happen. There is only a 1 in 16,000 chance this is an accident. If this holds up, everything you learned about matter might be incomplete. Today we go inside CERN's newest result. We trace the tiny particle breaking the rules, the missing force that could explain it, and the possibility that reality runs on laws we have never seen.

Hey guys! We’re now live on Spotify 🎧 James Webb just found something that should not exist. For decades, scientists believed the early universe was too young, too empty, to build galaxies this large. But the data says otherwise. Astronomers checked it 3 times. The numbers stayed the same. Tonight, you will travel to the edge of what is possible. A black hole older than the universe itself should allow. A planet where glass rain falls sideways in winds of 4,500 miles an hour. A galaxy shaped like a giant question mark, hanging in space like it is hiding something. Each stop breaks a rule scientists thought was solid.

Hey guys! We’re now live on Spotify 🎧 Right now, a machine older than your parents is falling through a region of space where the rules of physics don't behave the way we expect. It is nearly 17 billion miles from Earth, moving through darkness no human eye has ever seen. NASA built it to last 4 years. It has survived 49. This is Voyager, the fastest object humans have ever launched, drifting into a zone so strange that scientists still argue about what it actually is. In the next few minutes we go there. We will stand at the invisible edge of the sun's power, feel the sudden jolt when the universe outside changed in an instant, and listen to a sound Voyager captured that no one expected to hear, the hum of interstellar gas itself. Before we go, if you want to watch this journey before anyone else, we started a podcast on Spotify. Scan the code on screen or tap the link below to watch new episodes early, completely free.
