Alright, Jimbo, let’s see its atmospheric composition. Does it have a gas giant in its system?
How could would be to have radio communications with similarly tech-evolved aliens.
Very could!
That would be like so could man.
Could could could no scout no scout no scout
Unfortunately it is technically in New Jersey.
I’m gonna eat that planet
Only 150 light years away?! Wow, that’s practically next door! Now all we need to do is figure out how to go light speed and even then it’ll take a further 300 years just to know if the colonists got there safely or not!
When the first colonists arrive the planet will already be inhabited by humans since 100 years after they left we invent the warp drive. And trying to intercept them mid travel and board them on to the new ship is impossible since they travel near the speed of light in the darkness of space.
I’m pretty sure that’s a sidequest in Starfield. The ECS Constant colony ship set off in 2140 to colonise a planet, arriving in 2330 at the planet Paradiso, which had become a luxury resort planet for the rich, because shortly after the ship left, humanity invented the grav drive and every ship just zoomed right past them.
They’ve already sent galactic missiles to wipe us out before we can ruin them.
Well. This is quite a pearl.
I don’t have time to read a 16-page paper in detail, but I did want to know how the host star compares to everyone’s favourite local solitary K-type dwarf, Epsilon Eridani. It’s slightly less massive (~0.7 solar mass versus 0.8 for ε Eri) and quite a bit less bright (difference of about 0.1 solar luminosity), but I especially wanted to know about the age of the star. ε Eri is quite young and frothy, but the investigators here infer from the star’s motion that it belongs to the thin disk, up to a whopping 10 billion years old.
So we are definitely not talking about an ε Eri-type system. So that should be mean no dust disks, no crazy activity from the star, and no newish planets still carving out their places through the system.
You’ve really got to wonder about such an old planet, however cold and quiescent it may be. The potential paths for climatic evolution on such a world boggle the mind, however cold it is. You could get an episodically or formerly active world like Mars, a beautifully unstable oscillatory world like Earth, or something completely different. Assuming any atmosphere, of course (safe assumption?). And that’s without considering whether there are any other planets in the system.
I really wouldn’t spend too much time thinking about this candidate detection, as we have literally seen just the one transit, and we will need to observe this fellow for a while to confirm the discovery, learn about other planets in the system, and so on. The investigators themselves note that the transit was shallow (meaning difficult to detect), but the good news is that the host star is fairly bright, well within reach of amateur equipment. I wonder if citizen scientists will be able to follow the transits.
Exciting times.
quite young and frothy
haha, y-yes
Is there another similar format for this meme, but without this dipshit in it?
Does Bernie suffice?
Yeah this one should take over
Beautiful, Bernie is much preferred, thank you!
Send the pedofile billionaires
Why not ship them into Venus’ surface? Much closer, anyway.
Planet of the Rapes. Oh my God, I was wrong it was Earth all along!
I don’t like comparing inter and intra and extra species behavior to what humans call rape. Not a fun path to go down.
Send them on a generation ship without medbays with Hormel and Campbell’s and Dasani
Excuse me but if alpo’s good enough for daisy, it’s good enough for them
pedoplanet? this is how you get pedoplanet.
just kill them here so their bodies can rot and feed the planet.
They said send them, never said in what condition.
They’re probably so full of weird shit and plastic surgical filler they will contaminate wherever they die. Imo send them to mars alive. The microbes on them might help terraform mars if you send enough billionaires. All of them should do.
as far as we know this is the pedo planet
They’ll never make it
Found a calculator: https://www.calctool.org/relativity/space-travel
Assuming we want to accelerate at a constant 1g for half of the travel and then brake at 1g for the second half of the travel we would need 151 years to get there but only 9.794 years would pass on the ship. Depending on the mass of the ship we would need coupe million/billion tons of fuel (anti-matter).

What about accelerating 1g for 16 hours of ‘day’, then 8 hours of 3g ‘night’. It would be one hell of a weighted blanket lol.
It’s not just blanket entire body experience that force including internal organs… So i guess sleeping with tgat would be more than just uncomfortable
I say have a spinny ship that does that with the shape of the ring. Some kind of parabolic bullshit I’m sure there’s a way to get it to math without having to have a 1g ring and a 3g ring but that works too
The purpose of my idea is to average 2g without expecting people to function in 2g. Not just for the purpose of a weighted blanket
I mean, yeah. They’d probably have reasons to have stuff in the high grav areas besides sleep areas. I’m not a spaceshipologist I can’t think of anything but radon to keep there tho
Oh only a billion tons of anti-matter. Good thing we’ve already made a few nanograms, so in a billion years or so we’ll have plenty.
deleted by creator
Yeah, and antimatter converts to pure energy with e=mc^2 what means that 60 grams contains like Hiroshima worth of energy
In theory yes, in practice we have absolutely no idea how to actually do that and use the energy in an efficient or practical way. Even just on paper without limitations of technology or costs, we have no idea. Physics simply isn’t as clean or neat like that in real life.
50% chance of being in the habitable zone
Imagine sitting on a spaceship for 151 years just to discover your parents’ bet was wrong
Just imagine sitting on a spaceship for 151 years to find out they got there first because in 151 years space travel tech has improved so much they can travel there in 35 years.
Unless we figure out FTL travel that wouldn’t be possible.
Nah, Earth ran out of ideas in the 2020s
9.974 years
It’s only 9 years for you!
Imagine getting there and finding out a ship left 50 years after yours that flies faster and arrived 2 years before yours!
Ohhhhhhh, ok that’s clever!
How can it take 151 years to go 150 light years when not close to lightspeed most of the time? I get the 9 year thing, but 151 years seems wrong.
Smarter people than me on the internet calculate that at constant 1g you only need 2.5 years to get very close to speed of light. So I guess you accelerate fast enough and reach ‘almost speed of light’ very early in your travel and total time is almost as if you traveled at speed of light the whole time.
The main advantage of keeping accelerating when you’re at >90% of the speed of light is that it means you arrive faster in subjective time. You could take 160 years to get there and use ten times less fuel (or thereabouts), but the subjective travel time would go up by decades.
I think having constant gravity on the ship during the entire flight is also a big plus. Designing a ship where you can live in 0g for years and in 1g for years would be like designing two ships in one.
Not that smarter when they forget you’re running out of gas by the Oort cloud. Gotta spread
christianismcapitalism there and build a petrol station before we go further.Earth’s gravity being what it is a blessing cause it means we can do interstellar travel faster.
The closer you get to lightspeed, the slower you accelerate (from an outside perspective). It’s actually close to lightspeed for most of the time.
I just used the calc, it’s closer to 152 years. Which I assume means acceleration at 1g for about a year to reach .999c, and deceleration for the same time.
I just confirmed with dV= a*t, a year of 1g(9.8m/s/s) gets you just over the speed of light. I think it’s more complicated than that, If I remember right relativistic speeds require more and more energy to accelerate so you can’t ever “reach” light speed.
Most of the journey is spent traveling very close to light speed. It’s not a linear ramping up and ramping down of speed, since it takes more energy to accelerate the closer you get to light speed. Rather you quickly accelerate to near light speed and spend most of the trip working on that last small bit of velocity.
Constant acceleration at 9.8m/s^2 in a given direction will bring you close to the speed of light eventually, but yeah, I’m also not super sure how this math checks out
So a bit quicker than terraforming Venus by chucking several oceans worth of ice at it, and some cyanobactera once it cools down in a few hundred thousand years.
Time for Bussard to invent those collectors
I’m guessing you probably go faster than 0.9C after six months, given that the difference is 1 year.
And you’ll only need about 320 million GWh per ~80kg person… plus 4 million GWh per kg of supplies, equipment and ship weight…
Oh and also thats just the pure energy for acceleration/deceleration, not life support, steering, thrust ineffeciencies, take off, landing etc… 😅
Great Scott!
Your statement makes things sound a bit confusing.
To clarify, if you are inside the ship, 152 years will pass.
Edit: Nevermind. Time travel is stupid.
No, the people in the ship will experience less time then 152 years. Relativity tells us the faster an observer is moving, the slower it moves through time.
Cool lets pack up the billionaires and ship em over there.
I like the way you think. I think the sun is closer though. Probably easier to get too. I don’t know I don’t work on space travel.
Its actually easier to launch stuff out of the solar system than to slow stuff down enough to fall into the sun
I keep hearing that. Again - I don’t work on space physics, so forgive my ignorance on why. However- I’m good with billionaires taking as long as needed to get to our sun, some other maybe hospitable planet, or just dying in the cold of interstellar space while we observe a new holiday of them all fuckin’ off from terra firma.
guillotines need less energy than a light bulb.
Earth is traveling 29.8km/s around the sun. In order to go to the sun, you have to slow down. But to escape the sun from earth, you need to accelerate to 42km/s or just 12km/s relative.
I’m a certified internet space-e-ologist and can confirm that it’s all conjecture cuz we’ve never tried.
So for scientific purposes we should send a capsule in both directions.
cuz we’ve never tried
I was referring to chucking billionaires into the sun.
I’m sure the physics are wildly different so we need to test it, is my point.
Are you trying to get us fucking killed??? Those types of speeds are capable of reversing the Earth’s rotation, and turning back time! But even more likely is that the Earth will stop rotating and we’ll all get crushed because of gravity vs centrifugal force, and the world will stop being flat and then we’ll all fall off!
Hear me out what if we aaaiiimm it real good to the sun like “follow the bright ball buddy”?
That’s how you get comets
Is it because of our position?
As in, is it fair to say in terms of potential gravitational energy, that we are basically outside of the “centre” of sun’s gravity?
Not sure what you mean by the question, but it’s because we’re in orbit around the sun. We’re already going way too fast, so you’d have to slow down, and slow down a lot.
It’s actually a kinda’ fun challenge in Kerbal Space Program to hit the sun, and KSP’s solar system is much smaller than ours (meaning everything is much closer and easier to hit).
I meant whether we are farther away from the sun or not. As in, would it take less energy to hit the sun if we started from Mercury.
But now I realize that it’s our momentum given earths orbit. So I guess it would be harder from mercury cause it’s going faster?
Nope, it’d me much easier from Mercury. A higher orbit has more energy. A space ship has to speed up to increase it’s orbit.
Think of it like the old expression about what an orbit even is: You’re still falling same as always, you’re just moving to the side fast enough to always miss. Earth is ‘missing’ the Sun by a whole lot more than Mercury is ‘missing’ the Sun.
Basically because the planet the craft is being launched from is hurtling around the sun, you have to first cancel out all of that…let’s call it horizontal motion. Its the same way that orbits around earth work, you throw the thing horizontally fast enough and it will just fall around the planet. Want it to stop orbiting? Now you have to slow it down enough that it no longer falls around the planet but falls onto the planet.
Well while things are falling around (orbiting) the Earth, the Earth is falling around (orbiting) the sun. To launch something from earth and have it hit the sun, it first needs to get through all of Earth’s atmosphere, achieve orbit around the Earth, then exit the Earth’s sphere of orbital influence by increasing the height of the orbit so that the craft is no longer orbiting the Earth but orbiting the Sun, then decrease that orbit around the sun until eventually you get so close to the sun you fall into it rather than falling around it.
Now, if we were a real space program planning a real mission, we’d probably do something frugal and smart like using gravity assists to make the whole endeavor more achievable (which is exactly what the Parker Solar Probe did!)
Mars ?
The launch technology is already taken care of. We still need interplanetary radiation shielding and a landing system that doesn’t bounce them across the landscape like a ball, but that’s no reason we can’t start now.
Nah, let the billionaires eat some radiation and bounce around at high velocity on landing
but that’s no reason we can’t start now.
Recommend them to compute a sol gravity assist trajectory using chatgpt
Hear me out. What if we get that billionaire submarine company to build 2 big rockets, each one full of billionaire. We’d say one is going to do an exclusive tour near the sun, and the other is going to that fancy new planet. No one can go on both, because whatever, just bs that they leave at the same time. And limited seats to the highest bidder.
I mean the thing doesn’t even need to work. Just take their money and ship them to their doom, then build public houses with their money and put on space YouTube to see them squirm.
shhhhhh they don’t understand Hohmann Transfers, we can send them there regardless.
That could mess up the biggest computer ever, which is supposed to answer the question to which the answer is 42!
We could save a lot of money on life support system.
They’ll pull themselves up by their bootstraps on the way there!
Imagine arriving there after 150 years only for the colony to fail due to a random prion in the environment.
150 years travelling at light speed?
Check this out
And 50% not
That’s the reaction of billionaires when they realize they have a backup planet while they kill earth. Everyone else is fucked
137 is my favorite and lucky number, so I’m gonna decide this is the one that we find life on.
What happened in your life that this has become your lucky number? (Genuine question)
I actually don’t know, it’s been my favorite/lucky number since I was a kid. I’ve really thought about it and tried to remember, I’ve asked my parents etc. but no one knows. It’s a really cool number though, some random things:
The golden angle: https://en.wikipedia.org/wiki/Golden_angle
Age of the universe: https://en.wikipedia.org/wiki/Age_of_the_universe
The periodic table should end at 137 elements. Here’s a good blog post about it: https://gravityandlevity.wordpress.com/2013/04/27/where-the-periodic-table-ends/
And here’s just about the number itself: https://en.wikipedia.org/wiki/137_(number)
Here’s a great video about 1/137: https://youtu.be/RCSSgxV9qNw
And an article (there are many more about it): https://science.howstuffworks.com/dictionary/physics-terms/why-is-137-most-magical-number.htm
There’s a lot more where 137 pops up, but please don’t take this as me thinking it’s some deeper thing and that 137 is the truth of the universe or whatever else conspiracy mumbojumbo. I’m a science nerd and just think it’s fun to have it pop up in so many places of importance, and I know most of those are via our own completely subjective measurement scales (a circle being 360°, measuring the age of the universe in earth years etc.) Some have asked if it has anything to do with 1337, and it has no connection to that.
I have a fantasy (as in it only exists in my head, so far) sci-fi universe that I’ve been developing for most of my life where 137 is important that I hope to do something with in the future. Like writing a book, making a game etc. all I can say is that blade runner and 2001 are major inspirations for it. I gotta head to bed but can post more fun things about it tomorrow.
-94° is apparently habitable?
We let Exxon and Ford build petrol stations and oversized pick ups and SUVs first, then just wait about 100 years.
That’ll do it.
