LesserEvil: colonel0sanders: I bet the night sky on one of these planets looks amazingYes, but the view would literally kill you. Way too much radiation at the core for life of any sort to exist.
Coelacanth: There must be some incredibly old civilizations out there.
Huggermugger: Coelacanth: There must be some incredibly old civilizations out there.Just a couple thousand years more technologically advanced than ours would be incredible. But until someone masters faster-than-light travel, then we'll never have contact. Sad.
BigBooper: Huggermugger: Coelacanth: There must be some incredibly old civilizations out there.Just a couple thousand years more technologically advanced than ours would be incredible. But until someone masters faster-than-light travel, then we'll never have contact. Sad.There are many who believe that we have become advanced enough to know that FTL travel is impossible. I'm in the camp that believes that we don't know enough to be able to say what is or isn't possible. For those who say "but if were possible, someone would have visited us!" Unfortunately, that assumes that we are interesting enough, or unique enough to be worth visiting. I don't think that very likely.Of course, we may have been visited many times, and just don't know it. After all, bacteria have no knowledge that they are being watched when we look at them through a microscope.
ohokyeah: Who says E.T. hasn't visited already with absolute certainty? Maybe they visited earlier in our history as a passing exploration mission? We've barely begun to explore space in comparison to the duration of time we've existed as a species. I wouldn't be that surprised if they had passed by, collected some data, and continued on with their intergalactic travels or perhaps just collected data as they were propelled past us and we did not detect them or perhaps humanity did not yet exist.If it's not just a computer on board taking measurements, I think it's more likely to be A.I. as opposed to organic beings on board. If not A.I., then it would likely be creatures that reached singularity with their computers and could shut down for extended spaceflight and awaken upon a gravitational proximity alert or other change in environment. We would have been significantly more primitive in the time that they'd have been in the area, unless we still are incapable of detecting their technology (which still puts us as being primitive in comparison or perhaps they've explored an aspect of science we haven't yet and use systems we don't look for to detect somewhat like the difference between using A/C and D/C in electricity). It somewhat depends on what point in their technological progress the probe was sent out.We sent out the Voyager spacecrafts 35 years ago, and they are relatively primitive compared to what we could theoretically sent out for space exploration now, but we as a species have already sent out space probes. I would expect other intelligent civilizations at sufficient technological progress would eventually turn to the universe and want to explore it. The universe is incomprehensibly large and billions of years old though, and it would take time for any civilization to get around in it even if FTL can exist. Life itself may also not be inherently rare, but intelligent civilizations may be. Also, given the age of the universe, tens of thousands or millions of c ...
