i saw how fast that was. my travels seem so big. my life is tiny, my travels are tiny. nothing matters, what is life? these are the questions. explain to us how we are looking back at billions of years, billions of galaxies. we don t ever need, in our daily human experience, to understand the universe as a whole. our minds just are not set up to do it. i can t even wrap my mind around it. i started thinking about a good analogy for the universe of galaxies that we live in. you know what it is? it is air. if you look at the average separation between galaxies based on their size and the average separation between air molecules, it is about the same. if you want to have a volume of air that is equivalent to the number of galaxies in the universe, it is one cubic millimeter. you can think that you are small, but in some scale as you are really big. i suppose. as humans, there is this huge coincidence in the universe. if we go to the largest thing that we know of, the observable
it takes. the light from the sun is eight and a half minutes. you start talking about the nearest stars you re talk bth a few years. james webb is designed to look back at the first stars so we are talking like 13 billion years. think about it this way. our universe is made up of galaxies. so we are in a room and in this room there are all these air molecules flying around. galaxies in the universe are just like that. and the difference, though, is that the room is expanding. the universe is getting bigger. that changes everything. one thing it changes is it stretches the wave length of light. so that is why the james webb space telescope has the fancy, gold plated mirrors so it can look at infrared light. those mirrors will reflect infrared light with high efficiency because the light from those first stars by the time it reaches us the expansion of the universe has stretched
are they hiding? yeah. congressman, i mean, it seems to me, this is no longer a bug. it is the feature of a big part of the republican party. what do you think? well, i don t i don t know why anybody who is an elected official would be swapping air molecules with a conspiracy grunt on the border. i mean, it just it doesn t make any sense to me, as somebody who s, you know, taken the oath to defend this constitution. not only in the military but also as a congressman. it s appalling but you are seeing it everywhere, right, john? you have a q influencer, that got media credentials for trump s rally in florida. so, i think, right now, it s baked in. i think you are right, john. when you said this is more of a feature. right? the fact is that this has become this sort of apocalyptic good-against-evil conspiracy that s going on. but to actually pow around with somebody with a criminal record, somebody who was there, somebody who bragged about being there and take selfies with these,
no one knew. i mean, the tension in that room was so extraordinary. it was like there was no one breathing. i mean, you could just see all the air molecules sitting there not moving because no one was exhaling. the jury talked in and, you know, one of the cliches that i find is true about verdicts is if a jury is going to con difficult, they look away from the defendant but if a jury is going to acquit they look at the defendant. all those jurors were looking right at o.j. simpson. that famous shot you re looking at right there, the camera was right above the jury box, you never saw the jury on television, but they were all staring right at o.j. and i remember, you know, dominic dunn, a lot of people in that courtroom are gone, johnny cochran has died, dom anyone dunn the great reporter for vanity fair who was sitting a couple seats away from me he has
particles we can call it was the surface detectors was. one thousand six hundred sixty tanks make up the surface detector at the pier that was the observatory. all of them are filled with water the detector covers an area of fifty by sixty kilometers it s the largest observatory ever built. when cosmic rays reach the earth s surface here they re registered by the water tanks a single cosmic ray can produce a particle shalah that stretches over several square kilometers and a small tenuously detected by different containers. but it s not the only way how we can figure out the showers are actually. when the particles go from the atmosphere inside the air molecules. so you have this energy
