Episode notes

Red shift is like the dobbler effect, but for light. When something gets closer to youits sort of compressing the wave length. It's not actually changing frequency, because light doesn't actually lose energy as it moves. But over thousands of light years, there is a perceived change in the ency of that light. You can sort of think of red shift as like a loaf of raisin bread. And so if the universe is expanding, then the most precious information in the universe is travelling away from us. So all that light information, or electromagnetic information, is being shifted towards infered. The hubble can't see that stuff,. But something that could see frequency wave

This week we have another longform episode! David got a little obsessed with the James Webb Space Telescope (JWST) a few months ago and spent hours and hours researching and talking to experts so that he can try to explain it here on the podcast for Marques and Andrew. This one is a little dense but if you're even remotely interested in the mysteries of our universe this one is for you. David explains why the JWST is such a big deal and what we hope to discover once it begins sending back pictures.
