The Pioneer 10 and 11 spacecraft, launched by NASA in the 1970s to explore Jupiter and Saturn, exhibited an unexplained deceleration that challenged physics for 30 years until scientists discovered the cause was thermal radiation pressure from the spacecraft's plutonium power source, demonstrating that the universe's biggest secrets often hide in the smallest details.

NASA's Spacecraft Broke Physics... Until Scientists Found the TruthAdded:
Did you know two spacecraft once broke [music] the laws of physics until they didn't? It's the 1970s. NASA launches Pioneer 10 [music] and 11 into the void.
Their mission, explore Jupiter, Saturn, then keep flying [music] forever. For decades, they work perfectly, sending data across billions of miles, following every prediction, [music] physics in motion. But then, something impossible happens. Both spacecraft [music] start slowing down. Not much, just a tiny fraction, but enough to notice, enough to worry. Scientists check the math, run the numbers again.
The deceleration shouldn't exist.
Theories explode across the [music] scientific world. Dark matter, unknown forces, maybe Einstein [music] was wrong. For 30 years, the Pioneer anomaly challenges everything we know about gravity, space, and reality itself.
Teams of physicists hunt [music] for answers. New physics, revolutionary discoveries, the edge of human knowledge, >> [music] >> until someone looks closer. The spacecraft's plutonium power source radiates heat. That heat creates pressure, tiny, invisible, [music] constant pressure. The cosmic mystery that could have rewritten physics was just heat pushing [music] against metal.
The universe's biggest secrets sometimes hide in the smallest details. [music]
