      That's disappointing. I hate when i can't watch things live.

            Re: The Astronomy and Physics thread. And things of the like.

            Today's fun fact: Since we started broadcasting radio signals on Earth those signals have reached about 200 light years in diameter around the planet. To give you an idea of just how small that is, the Milky Way is about 180,000 thousand light years across. So if aliens were to respond they would have to be in that 200 light year bubble.

            We also know that we live in a pretty quiet corner of the galaxy so it's not all that surprising we haven't heard anything back.

            And I have a pretty strong opinion on this regarding astronomers and other people in related professions who like to say well hey we been broadcasting radio signals for over a hundred years and we haven't heard anything back so there must not be life out there.

            I find that to be very irresponsible of someone in that line of work to assume that. I guess it goes to show you that there are dumb people in every profession.

              The Astronomy and Physics thread. And things of the like.

              100 years in the history of time is nothing. Dinosaurs walked Earth 65 million years ago. Aliens could’ve been walking right alongside them, been like, “these big toothy idiots bout to catch this flameball” and peaced out. Hell, that could’ve been their one glimpse at Earth, then written us off. I bet we don’t look at the same areas once we’ve determined can’t be habitable under current conditions. Funny what 65 million years can do to a planet and its potential to sustain life.

              It’s all timing. Never say never.

                Exactly. I just surprises me that there are people who work in this field who don't realize the science behind the search for extraterrestrial life or are just to stupid to put any major though in it.

                Most people in the field understand and know better that we have only broadcasted to a tiny fraction just in our own galaxy.

                There are at least 200 billion galaxies in the observable universe. Most likely more. They all have a ridiculous number of stars. We know that most stars have planets, and we know that tons of those planets sit in the habitable zone. So somewhere out there is something or someone. And all of this doesn't even take into account potentially habitable moons.

                I think people don't take into consideration the real size of the universe and how many planets are in habitable zones. The Fermi Paradox and the Drake Equation are fine and dandy, but both lack some key data. When the Fermi Paradox says well where is everyone? Well maybe they are beyond the reach of how far we have sent signals or how far we have heard them.


                SETI has been in operation for about 50 years I believe and people say well they must not be out there then because we would have heard something by now. Ask any employee there why they haven't heard anything.They will give you some great answers and all of them are confident they will hear something any day now.

                Sorry for the big post.

                  On this same topic, if I'm able to contribute my own fun fact, and I'm not getting this from anywhere specific but I share this with my math classes (and I may be misspeaking on it), which actually sort of works counterintuitively to the "size" claims that are being made here though I promise that's not its intent:

                  A googol is a one, followed by one hundred zeros (10^100). A googolplex is a one, followed by a googol zeros (10^(10^100)). The number is so large, that if it was printed out on a strip of paper in size 1 font, stretching it across from one end of the observable universe to the other and back would still not be enough to fit that number.

                  So even given the expansiveness of the universe, that number still like... wins. Just wow in terms of that value's quantitative size.

                          Scientists at Queen’s University Belfast said the flash was so luminous they initially thought it was in our own galaxy, with one researcher claiming 'there hasn’t really been another object like this.' (Stock)


                          I hope we can figure out what this was, because by all accounts it was something extraordinary.

                          Do the same thing tomorrow. And the next. Now do it forever.

                                How do we even know that? Isn't dark matter a theory to begin with?
