schplurg Posted July 30, 2020 Posted July 30, 2020 I think that if aliens with the technology to cross the vastness of time and space decided to come here that they would not be interested in abducting hillbillies and uh....probing them. Picking up cows and dissecting them? Probably not. If anything, any life form of any intelligence would stay far far away from our dumb violent species. I know I would. I think we would be far inferior to them in intelligence, as bass are to us. And look how we treat bass For all our intelligence we can't even effectively communicate with any other animal on the planet. They might see us as so dumb that they can't communicate with us either. They would likely think nothing of us at all. And if aliens behave even remotely similar to humans we'd be dead already. They'd kill us for sure. We sure as heck would try to kill them. It's what we do. They certainly would not invite us to join the Federation Of Planets! The idea that they'd come and enlighten us with their technology and fly around the skies in "impossible" flight patterns, teasing us with their possible presence is silly to me. Aliens being on our planet would be the biggest story in history. I don't think ours, or any government is competent enough to keep such a secret. Why would the aliens hide anyways? Oh sure, they're going to trust the morons who run our country and hang out with them? No frickin' way. If aliens are intelligent enough to get here then they are intelligent enough to stay away. 1

Here's a quick article and vide9s that talk about that: https://www.space.com/29859-the-illusion-of-time.html Then we get into relativity. Imagine a 15-year-old traveling at 99.5 percent the speed of light for five years (from the astronaut's perspective). When the 15-year-old gets back to Earth, according to NASA, he would be only 20 years old. His classmates, however, would be 65 years old. We can even see the effects of relative time on our own world. Did you know that the clocks on GPS satellites don't run at the same speed as clocks on earth? Here's a primer on "time travel" that covers this and more: https://spaceplace.nasa.gov/time-travel/en/ Personally, in the long run I don't think time is an issue in reaching far galactic places. I think that the energy required is a bigger issue. I have a cousin who is one of the top aerospace engineers in the world he he can go on about this stuff for days. I certainly don't understand all of what he talks about, but I still find it exciting and fascinating. As far as he is concerned it's not "if" we can solve the physics of deep space travel but "when". That could be thousands (or more) of generations from now. The question is can mankind avoid destroying itself before that happens. That's also why many scientists think the number of deep space faring aliens is probably low - they destroy themselves before figuring it out. That's Special Relativity, when you are reaching such high rates of speed. Let's say we are correct that traveling light speed is impossible. They'd need to get here some other way which would not have time dilation as a side effect. I'm making this part up (we don't know if wormholes exist or are possible), but wormholes may/would not have that effect. If you travel close to the speed of light, as already mentioned, when you arrived back home everyone you knew would possibly have died of old age. Depends on how fast/long you are gone. Based on that, if one did actually reach light speed time would stop for you - to you, you could go anywhere instantly. But the opposite would happen to the rest of the universe. You would "watch" the entire life and death of the universe in an instant. So going the speed of light would not help. Our sun and every star in the universe would be dead and you'd be very late to the party Going almost the speed of light would take hundreds of billions of years to get across our galaxy alone (to an outside observer). Cool stuff though, I love it. 1
Heartland Posted July 30, 2020 Posted July 30, 2020 Quantum entanglement - spooky action at a distance as Einstein called it, make me believe that the time/distance problem may have answers. 1

They will announce it right at the beginning of November and no one will even care. Elon is an incredibly interesting person, I would guess he is probably high functioning Savant. Check out Rogan's podcast when Elon visited. This guy is ahead of everyone IMHO. 1
Hook2Jaw Posted July 30, 2020 Posted July 30, 2020 I've captured an alien. The heck is this thing? I barely stopped it from eating the shiny skirted thing I was watching flash in the water.
