Since then, more than 108 billion members of our species have ever been born, according to estimates by Population Reference Bureau (PRB).23 Jan 2020 ___ https://www.prb.org/howmanypeoplehave... ___ | how many earth like planets in the universe? ___ How do scientists know that there are billions of other solar systems like us in the Universe? They don’t know that, and I’ve never come across one that made that claim. What they do know is that based on measurements of portions of the sky and extrapolation, that there are about 100 billion stars in our galaxy and up to 10 trillion galaxies in the universe. That means up to 1,000,000,000,000,000,000,000,000 stars. About 7.6% percent of those stars are class G stars (like our Sun). We haven’t been to any of those stars to see if they have solar systems like ours. But we have been studying a very small portion of the sky in the constellation Cygnus, using the Kepler telescope. Kepler doesn’t allow us to visually see planets around far away stars, but it allows us to detect changes in the light coming from those stars caused by planets passing in front of the star. From this analysis, the estimates are now that almost all class G stars have at least one planet. That means there are up to 76,000,000,000,000,000,000,000 stars similar to ours and almost all of them have some form of planets. Based on the Kepler observations, it is now estimated that a quarter of those stars have at least one rocky planet similar in size to the Earth and in the habitable zone. That means there are up to 19,000,000,000,000,000,000,000 stars similar to ours with at least one planet similar to Earth. 19 000 000 000 000 000 000 000 written in lowercase: nineteen sextillion ___ https://www.forbes.com/sites/quora/20... ___ | fermi paradox= solutions ___ It is possible, however, that present scientific knowledge cannot properly gauge the feasibility and costs of such interstellar colonization. Theoretical barriers may not yet be understood, and the resources needed may be so great as to make it unlikely that any civilization could afford to attempt it. Even if interstellar travel and colonization are possible, they may be difficult, leading to a colonization model based on percolation theory.[114][115] Alien species may isolate themselves from the outside world It may also be that intelligent alien life develops an "increasing disinterest" in their outside world.[90]:86 Possibly any sufficiently advanced society will develop highly engaging media and entertainment well before the capacity for advanced space travel, with the rate of appeal of these social contrivances being destined, because of their inherent reduced complexity, to overtake any desire for complex, expensive endeavors such as space exploration and communication. Once any sufficiently advanced civilization becomes able to master its environment, and most of its physical needs are met through technology, various "social and entertainment technologies", including virtual reality, are postulated to become the primary drivers and motivations of that civilization.[113] ___ https://en.wikipedia.org/wiki/Fermi_p... ___ emergence/novelism |= e-rtrn |_ noumenon= life is ephemeral but truth is forever _ phenomenon= lifes meaningful coz we make it so! consciousness_10^0-to-10^12hz_orch-or | macrostate _ noumenon |= e-rtrn | tplanck/tpoincare=5.391×10^−44s/10^10^10^10^2.08yrs | microstate ___ taiyc1 |= xnxp/inxj |= serendipity_makes-life-interesting! :) ___ mind blown! enjoy! :) thanks 4 the support n have a great day!
