Good evening, stargazers! I'm thrilled to share with you a truly spectacular event that occurred on November 25th in astronomical history—one that fundamentally changed how we understand the cosmos itself.

On this date in 1915, **Albert Einstein presented his field equations of General Relativity to the Prussian Academy of Sciences**. Now, you might be thinking, "Wait, that's physics, not astronomy!" But hold on—this was the moment that revolutionized astronomy forever. Einstein's elegant equations didn't just describe gravity; they rewrote the rules of the universe itself.

Before this November day, astronomers were essentially working with Newton's equations, assuming space and time were absolute and unchanging. But Einstein's revelation showed us that massive objects actually *bend* spacetime around them—imagine a bowling ball dropped onto a stretched rubber sheet, creating a depression that smaller balls would roll toward. This wasn't just theoretical nonsense; it had real, observable consequences!

And here's where it gets truly wild: just a few years later, in 1919, Sir Arthur Eddington would actually *prove* Einstein right by observing starlight bending around the Sun during a solar eclipse. Without Einstein's equations from this very November day, we wouldn't understand black holes, we couldn't explain the precession of Mercury's orbit, and modern astronomy as we know it simply wouldn't exist.

So here's to November 25th—the day the universe revealed its deepest secrets!

This is your Astronomy Tonight podcast. Good evening, stargazers. I'm
thrilled to share with you a truly spectacular event that
occurred on November twenty fifth and astronomical history, one that
fundamentally changed how we understand the cosmos itself. On this date,
in nineteen fifteen, Albert Einstein presented his field equations of

general relativity to the Prussian Academy of Sciences. Now you
might be thinking, wait, that's physics, not astronomy, But hold on.
This was the moment that revolutionized astronomy forever. Einstein's elegant
equations didn't just describe gravity, they rewrote the rules of
the universe itself. Before this November day, astronomers were essentially

working with Newton's equations, assuming space and time were absolute
and unchanging. But Einstein's revelation showed us that massive objects
actually bend space time around them. Imagine a bowling ball
dropped onto a stretched rubber sheet, creating a depression that
smaller balls would roll to. This wasn't just theoretical nonsense.

(01:03):
It had real observable consequences. And here's where it gets
truly wild. Just a few years later, in nineteen nineteen,
Sir Arthur Eddington would actually prove Einstein right by observing
starlight bending around the Sun during a solar eclipse. Without
Einstein's equations from this very November day, we wouldn't understand

black holes, we couldn't explain the procession of Mercury's orbit,
and modern astronomy as we know it simply wouldn't exist.

Gabe Ortiz becomes a third-highest ranking officer in all of Texas while his younger brother Larry climbs the ranks in Puro Tango Blast, a notorious Texas Prison gang. Gabe doesn’t know all the details of his brother’s nefarious dealings, and he’s made a point not to ask, to protect their relationship. But when Larry is murdered during a home invasion in a rented beach house, Gabe has no choice but to look into what happened that night. To solve Larry’s murder, Gabe, and the whole Ortiz family, must ask each other tough questions.
