Fossil fuels are made from the remains of extinct organisms that have been exposed to millions of years of heat and pressure. But in the case of coal, these organisms consisted largely of some downright bizarre plants that once covered the Earth, from Colorado to China.
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.
The first era of our current eon, the Paleozoic Era, is probably the most deceptively fascinating time in Earth’s history. With near constant revolutions in life, punctuated by catastrophic extinctions, it is also one of the most chaotic. Correction! At 9:19, we erroneously refer to Dimetrodon as an herbivore. It was definitely a carnivore. We […]
In Cretaceous times (around 100 million years ago), North Africa was home to a huge river system and a bizarre menagerie of giant prehistoric predators — including the Spinosaurus, a dinosaur even more fearsome than the Tyrannosaurus rex. Nizar Ibrahim uses paleontological and geological data to reconstruct this “River of Giants” in surprising detail. Lesson […]
The human brain is one of the most sophisticated organs in the world, a supercomputer made of billions of neurons that control all of our senses, thoughts, and actions. But there was something Charles Darwin found even more impressive: the brain of an ant, which he called “one of the most marvelous atoms of matter […]
Agencia SINC La industria tabacalera es consciente desde 1960 de la adicción que la nicotina provoca en el consumidor. Sin embargo, no fue hasta el año 2000, tras décadas de negación pública, cuando la compañía Philip Morris admitió que esta sustancia es uno de los principales factores causantes de la dependencia de los fumadores, tal […]
MEC Gisela Aguilar Martínez Nacido en los cañones de La Huasteca y culminando en Cadereyta, entre las avenidas Constitución y Morones Prieto existen más de 300 especies y para muchos automovilistas eso pasa desapercibido: es el ecosistema que habita a lo largo de 45 kilómetros del Río Santa Catarina. Al momento de mencionar al Rio […]
Could we be living in a simulated universe? Brian Greene and Neil deGrasse Tyson discuss this possibility.

SPACE, TIME, AND THE NATURE OF REALITY. 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 […]
The speed of light is often cited as the fastest anything can travel in our universe. While this might be true, the speed of light is the EFFECT and not the CAUSE of this phenomenon. So what’s the cause? On this week’s episode of Space Time, Matt helps explain what the speed of light REALLY […]
Agencia SINC Reconstruir los modos de vida de los humanos prehistóricos no es tarea fácil. El paso de miles de años reduce los antiguos asentamientos a poco más que restos de herramientas de piedra, huesos y huellas de hogueras y otras estructuras. No obstante, el estudio de los huesos de animales cazados por las sociedades […]
Now that gravitational waves are definitely a thing, it’s time to think about some of the crazy things we can figure out with them. In some cases we’re going to need a gravitational wave observatory – in fact, we’ve already built one.
Agencia SINC El interferómetro ALMA (Atacama Large Millimeter/submillimeter Array) y el experimento APEX (Atacama Pathfinder Experiment) han ‘buceado’ en las profundidades del espacio hasta la época en la que el universo tenía una décima parte de su edad actual, es decir, cuando tenía unos 1.400 millones de años, y han sido testigos de los inicios de […]
