>> the visible part of our galaxies -- >> the milky way? >> yes. it's about 25,000 light years from where we are to the center of the galaxy. we are halfway out. so it's about 50,000 light years from the center to the edge of the visible galaxy. the dark mart is much further. >> can you translate that into earth miles? >> 6 trillion miles per light year. so you have to do some multiplication. >> how many light years? >> across the whole galaxee is 100,000 light years. so 100,000 times 6 trillion. >> and the galaxies you mentioned earlier over 100 billion of those of comparable size? >> yes. >> what about the age of the universe? >> that is a little harder. the best estimate right now is about 13.7 billion years. to do -- we have to calculate things like age. it's not something you can measure. and it depends on knowing eye number of other numbers very precisely and we don't know the numbers that precisely yet. so what i say is that if around 40 billion years. quite sure of that. but i don't think that we can be quite sure it's 13.7. it might be giv

what we found if you look at a galaxy, galaxies are moving away. what we guessed back in the '90s when i was a kid learning cosmology that galaxies are moving away but they're pulling hooper all these hundred billion galaxies are exerting a gravitational pull. so even though they're moving apart, we should be moving apart ever so slowly. so there should be a deceleration in the universe. there were two teens that decided to go measure the desell ration. you know, with of them, in fact, named their collaboration the high registertive supernova team measuring the desell ration of the universe. imagine their embarrassment when what they measured was that the universe is accelerating. so if you look at a galaxy it's moving away from you. you measure its velocity and you come back a billion years later. you measure the velocity to the same galaxy it will be moving away from you faster. so the galaxies are not only moving away they're accelerating away from us. this is the most important experimental discovery in cosmology since the 1960s at the very lea

they burn out teeeleven galaxy were the center of the galaxy has a black hole the million times of the mass of the sun but if you wait long enough every star wilt spiral in and become part of that black hole then it will evaporate and there will be nothing left. how many years between now? one googled good old fashioned. not if the search engine. 10 to 100 years from now that is the of the space after that it is hard to make sense. it is only 10 to the 10 year old right now also don't go change your investment portfolio on the basis of this information. [laughter] >> it is about explanatory methodology. i was pretty cool with the aerodynamic explanation and the low entropy stay distribution and a beautiful explanation but then i wonder if the explanatory it should you want to scratch after that is worth the price? with a speculum is that are happening it occurs that every theory has primitives and you can wonder why is the speed of light exactly what it is an any different number and all explanations have to stop. what is moving new in syncing why the initial state is the if you have g

astro physicists say this shows a galaxy in a growth spurt.alaxy 10 billion light years from earth is making new stars 250 times faster than our own home, the milky way. >>> and at least one member of the international space station crew is ready to trade his space suit for a snorkel. a flight engineer took this picture of the blaahamas and posted it on twitter saying i just want to dive into the bahamas. that brings us down to the wire. dive into the bahamas. >>> what we will miss the most when the health care reform debate is finally completed and is finally over is the tendency of those on both sides of the issue to say, i don't know, over state their case? our top three today the most outrageous moments in the fight over health care reform and we begin, number three, with sarah palin. >> we're going to be subject to bureaucrats deciding, panels and commissions deciding just like they do overseas who will be worthy of receiving the health care that government is going to provide. so that is the death panel that i referred to. >> oh, sarah.

so you look at galaxy rotating and it doesn't work.you look at the stars, it's not rotating like it should. >> there's also real evidence which is very cool, so even though dark matter is dark, you could have a light object behind it, something that emits light behind it and einstein taught us that dense objects will actually make light bend. so you see evidence the light is bending even though you don't see anything there because it's dark you see images of dark matter. >> einstein taught us that light bends. >> it bends in the presence of gravity. >> rose: there's this other thing called the theory of everything and it came up when i was interviewing walter isaacson on his book. what's the theory of everything? >> (laughs) >> rose: because einstein was fascinated about it. was he not? >> it's interesting. the single force, the single equation, people would love to have that. what's interesting about the had ron is we're working very differently. we're working incrementally. we're saying we can't answer that because it's many organism

the galaxy s from samsung. it's all about, larry, the peril and promise of mobile broadboan. when i hit that link on my blackberry will i get to that link and that spot and that internet spot? that is the talk here. which companies will do the rollout and how can you invest on them? all that coming up on "power lunch." >> all right, michelle, you look really sipsyched. >> my wife won't let me have a blackberry because i will be addicted to it. >>> companies cashing on a red hot slice of the market. >> they are getting one thing through. >>> the market call heading into this afternoon's trading session. we'll be right back. >>> okay, welcome back. some consumers are looking to save some green and so they're going green when it comes to their hot water bills. more and more homeowners are discovering that the cost savings of solar water heating systems are really worth it. wendy is here to explain what with the main street business report. >> hi, how are you? >> good. >> put these on in my house and offset two-thirds of your hot water bill is couple panels on the roof, hot water

it's like a long time ago in the galaxy far, far away. what was that about? i know as haynes and i have gone around to talk about the book, the question that you ask is one of the regular questions that we get. and were there includes to this? now, i would be lying if i said that i had any sense of where we would be a year after the election. you know, i don't think anybody foresaw what happened. and it's a reminder than there's nothing linear about american politics or politics in general. you can never draw a line from any moment and project out. people happen, events happen, people do things. if you look at the complain, i always thought going through the obama complain there was an inherent contradiction on the message. on the one hand, the message of hope and change. there was the rhetoric of somebody who had the promotion, made the promise, and, in fact, seemed to embody some of that promise. being able to take american politics to a different place. that after the very de polarization that somebody would bring the country together. there was moments in

plus, the solar system itself is circle around the center of the galaxy every 226 million years. and this is a trip that's worse than froto's trip in "the hobbit." it has so many risks, dangers and appalling circumstances that it's ridiculous. and every one of those things changes our climate. what is nature doing? these proliferating as many species as possible to find as many niches as possible before the next great extinctions so that she manages not only keep life alive but keep it thriving and developing in new ways. so, yeah, we're in for it big time but the problem is we humans evolved in the middle of all these ice ages and global warmings and those are what made us clever. they gave us the challenge of overcoming over and over again. a niche isn't something that's there. a niche is an opportunity to invent something. if we invent a metabolism. if we invent a way to take advantage of something of something that was a waste land, all of a sudden that waste land is a niche. so niches depend on our ability to create. and our ability to get beyond this next climate challenge

we sit here and the campaign is like star wars, a long time ago in a galaxy far, far away.hter] you know, it's what was that about? i know as haynes and i have got around to talk about the book the question you ask is one of the regular questions the we get and were their clues to this. now, i would -- i would be lying if i had any sense of where we would be a year after the election. i don't think anybody foresaw what happened and it's a reminder that there's nothing linear about american politics or politics in general. you can never draw a straight line from any particular moment and project out. things happen, even in its having. people do things. but if you look at the obama campaign, always thought even going through the campaign that there was kind of an inherent contradiction in the message of barack obama. on the one hand, there was the message of hope and change. there was the rhetoric of somebody who had the promise, made the promise and in fact seemed to embody some of the promise of being able to take american politics to a different place that after the very d

every 23,000, 42,100,000 years plus the solar system itself is circling around the center of the galaxy every 226 million years and this is a treat that is worse than frito's trip and haul it. [laughter] it's got so many risks, dangers and appalling circumstances that it's ridiculous, and every one of those things changes the climate. what is nature doing. she is delivering as many species as possible to find as many matches as possible before the next great extension so that she manages to keep not only life alive but keep it thriving and developing and new ways. so yes, we are in for it big time, the problem is we humans evolved in the middle of all of these ice ages and global warming and they were what made us clever. they gave us the challenge of overcoming them over and over and over again and inventing a way out of things. let's redefine something in biology. a niche isn't something that's there. a niche is an opportunity to invent something. if we invent metabolism, if we invent a way to get a vintage of something that previously goes to waste land of a sudden that the waste lan

the center of the galaxy. our heading's been altered.l locomotion. endoskeletal. contiguous external integument. hmm. i am captain jean-luc picard of the federation starship enterprise. hierarchical collective command structure. who are you? interrative. and i would appreciate an explanation. i can help you, captain. mr. barclay? i thought it would be fatal if you left the hodeck. the cytherians have reintegrated me, sir. the probe was designed to instruct outsiders on how to reach the system. they failed with the argus computer and with the computer on board the shuttle what do you want of us? the same as you. mr. barclay? you're both on the same mission. mission? as we are. the only difference is that they never leave their home. they bring others here. their only wish-- an exchange of knowledge. ey want to know us. captain's log, stardate 44721.9. to federation space. we bring back knowledge of their race that will take scholars decades to examine. for his experience. how much do you remember? i remember doing everything. i just don't
