>>7804956 Because it's expensive is pretty much it. Space Agencies have limited budgets and building. There have been plenty of proposals for doing so, but none of them have taken off.
Pic related. It's a proposed NASA probe that would have gone 1000 AU in under 50 years (Via a 10 year long ion engine burn taking which would have ended at 100 AU out) in order to obtain lulzy parallax measurements.
We could probably do faster if we decided to make a probe that was on the end of a space launched system with a trajectory that took advantage of more than a few (and including the Sun's) gravity wells simply to see how fast we could get something to go.
>>7805371 The Communications system planned was a 10 W Laser transmitter with a 1 meter telescope for receiving. The probe's laser would be received by a 10 meter telescope in LEO which would relay the data to earth.
(Say) There's plenty of intelligent life in the universe - our own galaxy is teeming with it, on many thousands of worlds. But everything is so fucking far apart that none of them can communicate with each other. Each is in his own private hell.
>>7804829 That's a pretty good accomplishment for a species that was hanging about in trees a mere 120K years ago (some still are). What you're asking for is FTL travel, which there are a number of theories of how to accomplish and you may even see in your lifetime. The net best thing is close to light-speed travel, that you will definitely see in your life time.
>>7805657 I had a theory that you only get one infinitely repeating variable per equation, so each celestial object has a single unit with "life" on it. You can scale that down to "this is the only planet with life" but you can also scale it up to "there is one planet in each solar system with molecular structures that iterate indefinitely"
Those molecular structures will have to operate on whichever physical properties the surface of the planet pertains to, though. Could be completely abstract of a human. Just psychology represented through matter.
It makes me like to think that every planet has life, just life fit for that planet. Some kind of sentient rock formation or fluid dispersion that iterates around the planet on a yearly cycle. Life.
It also makes me think that the closest thing there is to "earth" with "humans" and "psychological creatures" is earths mathematical position on the next neighboring galaxy, out of the milkyway completely.
again, though, being one "chaos equation" in the system, that's assuming each individual system gets a chaos equation, and not that earth is the universe's chaos equation
>>7805657 >(Say) There's plenty of intelligent life in the universe - our own galaxy is teeming with it, on many thousands of worlds. But everything is so fucking far apart that none of them can communicate with each other. Each is in his own private hell. so just like earthlings: billions of individuals who can hardly communicate.... and with no certainty that other humans are ''humans''
>>7804829 >>7804829 Because we have to start doing it some time. And they did it. It is a beginning, exploring the edges of our Solar system. So you think the first probe humans would send into space would be some huge ship with people on board and billions of dollars worth equipment? In science we go step by step and dont use everything we have at rhe first time. We also had the bow and arrow before we had the atomic bomb.
That was decades ago. Technology has advanced since then, perhaps not to the degree that would enable a manned interstellar voyage, but nonetheless there have been advanced in propulsion and such. Give it another century or two, I'm sure that humanity will discover a feasible way to travel to at least, the nearby stars.
>>7805101 >Helios 2 hit 157k mph. Yeah, at perihelion... not really the same thing. Oberth effect is fucking massive down there though, so if you could bring 5-10 km/s of DV down to about 1/10th of an AU we could dwarf Voyager's Sol C3 speed, no slingshots necessary (AND since we aren't constrained by planetary orbits we would have a much wider range of possible directions we could fling the probe in, if it matters at all). >We could probably do faster if we decided to make a probe that was on the end of a space launched system with a trajectory that took advantage of more than a few (and including the Sun's) gravity wells simply to see how fast we could get something to go. The planets won't be lined up for another Grand Tour for another century and a half. Multiple gravity assists are only useful for raw velocity when things are perfectly aligned; otherwise it's generally more desirable just to dig into the deepest gravity well as hard as you can instead, regardless of where it sends you. That's why Voyager 1 managed to outrun Voyager 2, despite only performing 2 assists instead of 4; the detour imposed on Voyager 2 actually cost more velocity than the extra assists provided.
>fast forward one hundred thousand years in the future >humans somehow survived all this time and have gained the ability to travel to every star in the galaxy, everyone is ecstatic of the possibilities >fast forward another fifty thousand years >various ruins of ancient, million and billion year old alien civilizations are found >evidence of some being capable of interstellar travel >all destroyed by some sort of war >no currently living intelligence is ever found >turns out we were the last in our galaxy to evolve sentience
>>7804829 Voyager was the happiest accident this world ever created. It was literally made to slingshot off of the alignment of the planets. No matter how much time passes, there will NEVER be an event as inspiring to me as the Voyager story was and is.
>>7804843 Some alien species is gonna find readings about our desperate attempt to leave a mark in the universe. And that's when they'll have earthaboos who think End of Evangelion is a masterpiece from a race of people who were far superior to their own.
