🚨 Elon Musk says physics has stagnated and AI could overtake scientific research. He says progress has relied on expensive hardware like colliders and telescopes, that slows discovery.

Jim, you just described the greenhouse effect while claiming to debunk it. Impressive.\ Yes, CO₂ absorbs infrared and re-emits it in all directions, including back toward Earth's surface. That downward re-emission is exactly what warms the planet. The word "trap" is shorthand for a process you just correctly described. Your own explanation is the mechanism. This is like arguing a wool blanket doesn't keep you warm because it doesn't "trap" heat - it just slows its escape in every direction including back at your body. "CO₂ re-emits in a millionth of a second" - correct. And then the O₂ and N₂ molecules that absorbed that energy via collision also re-emit. The atmosphere is dense. Photons don't escape to space on the first try. That's the entire point. "CO₂ is essential for cooling the Earth" - this is the only interesting part of your reply. CO₂ does radiate energy to space from the upper atmosphere. But as CO₂ increases, that emission layer rises to colder altitudes, which radiates less efficiently - net result: warming. This is radiative forcing 101. You didn't catch a half-truth. You described a physical process accurately, misread its implications, and called it a gotcha. The thermometers are not propagandists, Jim.
