UFOs, and lots of 'em!

TW, there are close to 30 potentially habitable planets within 100 light years of Earth.

There are about 13,000 star systems within 100 LY. There will be a lot more than 30 'potentially' habitable planets within that distance. How many long term habitable? I'm going to guess zero-other than Earth. Gravity will be too high or low, or temps, or they wouldn't have had cyanobacteria loading the atmosphere with the right amount of oxygen,no multi cell life for us to eat etc etc... None within 100 LY anyway...maybe a few within 1000 LY. I bet there are less than a 1000 planets in the galaxy that are essentially identical to earth with similar evolutionary paths that we could just show up and thrive on.

Edit...This person says there are about 113,000 stars including M class dwarfs within 100 light years https://www.answers.com/Q/How_many_star ... s_of_earth
"
A few years ago the Hipparcos sattelite measured distances to ~120,000 nearby stars, so somewhere there is an exact answer to this question. I don't know to what magniture Hipparcos could measure parallaxes for, and whether it could see the dimmest M dwarfs 100 light years away, so it may or may not have observed all the stars within 100 light years. Given how dim M dwarfs are, I would guess it probably didn't. In other words, somewone probably figured out exactly how many stars in the Hipparcos catalog are withi 100 lightyears, but I don't know that answer, or whether that ould be all of the actual stars within 100 lightyears (~30 parsecs).

So, here's an estimate. In our part of the Galaxy, the average distance between stars is about 1 parsec. (30 PC~100 ly). 4pi/3* (30 PC)^3 is about 113,000 stars out to a distance of 30 PC or about 100 lightyears. Now, about half of the star systems are binaries or multiple systems, so 113000 + 113000/2 is about 170,000 stars. That's a lot!

As for how many have planets, well, we have detected several hundred extrasolar planets, but they are almost all very large planets orbiting very close to their parent star, simply because this is what is easiest to detect. The more we look, the more we'll probably find, so there are probably many thousands of planets within 100 ly of our solar system."

So, this is actually a thing.

Does anyone else find this vaugely unsettling?

I'm stealing this from another very recent thread and putting a expanded 'comment' on it....
Watch these vids in order. You will need 2 hours.

C'mon guys....connect the dots....Pandemic or plandemic, overpopulation, climate crisis, the Great Giveaway, global equality, wealth distribution, NASA hiring people to figure out how to tell everyone the truth(among other classified programs),- and one telescope(JWST) that is capable of not changing just our way of doing astronomy, but capable of changing the long term evolutionary path of our planet...Possibly on the scale of being bigger than the mastery of fire. JWST will be able to possibly detect waste heat from tech, pollution...etc-To save you time, the things described in the third video from 15:45 to 34:00 could be detectable by JWST -if all goes well on its deployment.
Maybe Kael has some advice for you on 'adapting'...
Gonna be a wild ride....

The possibilities are endless.

^^^Big difference between potentially habitable and show up- no environmental suit, stand naked and breathe the air that doesn't have dandilion fluff that if inhaled would kill a T-rex in 2 seconds from a allergic reaction. Our own planet can kill us from its biology, imagine what another earth would be like. That's what I meant by parallel evolutionary paths. Just because a planet is earthlike in every way doesn't mean we could survive its biology.

Yes but wouldn't it be interesting if we could and had a way to get there without taking more than a lifetime to do it.

Beam me up Scotty!

Anyone born now may see that.
Anyone born now has the potential to have their consciousness continue until the age of starlight ends in 150 trillion years...if we hook up with the right neighbours. Think about that...
2nd edit...What I mean by the last statement is that there are already companies like Alcor cryonics. Also, some believe we are less than a century away from downloading our sentience, mind, our memory into a computer. If we then met up with a class 1 civilization or higher that was able to ensure they have a immortal existence free of aging, and the problems we regular low tech, short living mortals have. If we took another civilization off the table, even if we could stop and reverse the aging process, we would have no need to be in a super hurry to grow up, make money, reproduce, get divorced, lose money the way we do. It would fundamentally change our entire existence and it would save the planet from human over reproducing. Also, we could live long enough to explore our solar system within our extended lifetimes. Even if we could extend our lifetimes into the thousand year range, it still wouldn't be long enough to do interstellar spaceflight. For that, we would need to live for tens of thousands of years. Even a short trip to proxima centauri at 1% C (3000 times the speed of a rifle bullet or 6.6 million mph) it would take 426 years one way. A trip to Trappist1 would take 3900 years one way.

And when we meet the neighbours in 9 months or in 900 years in their various forms, we will find that have actually been with us all along...perhaps millions of years. They may say... " Welcome to the party" or " Stay home"

Paul,
I wish you lived long enough to see this.

I didn't want to post this until JWST was up and working....but hey, why not now.

How far are we from having a neutrino/'quantum memory' telescope? 100-200....1000 years ? OHHH SNAP! Don't ya just hate me now? Think getting rid of your google search history is hard? You would have to destroy the universe before it became the universe to delete your neutrino history... Yeuupper....everything you have ever done....recorded to exquisite detail for barely more advanced than us beings observing entertainment. And, if this is a 'simulation' universe, eventually even we assuming we last, could evolve to the point as to where we could playback every event, from everywhere.

These are the very close systems with confirmed, potentially habitable exoplanets that I think we may want to have a interest in just due to proximity. The list does not include systems that are closer and have confirmed planets...-but none that could be habitable to us, or creatures like us, so I didn't include them.

This is the 'known' stars /brown dwarfs within 16 light years list. Some of these have potentially habitable planets of which I have listed in previous post.

You and I wouldn't be alive but in as little as 30 years ,humanity could find out if it would be worth doing the trip to the Alpha Centari system with a project called Breakthrough Starshot. It involves firing a huge laser at a bunch of micro probes with solar sails attached, theoretically accelerating them to 20% the speed of light or about 100 million miles per hour. It would take about 25 years to get there plus signal return time of just over 4 years.
