nothing? how many light-years away are they again?

>>15056132
Like 40. We could still theoretically send a ship to it with just a few generations of humans though

>>15055821
>TRAPPIST-1
Obviously a planet full of trannies

>>15056227
damn we have to get there NOW

>>15055821
We carry on like normal?
In practical terms it changes nothing and most humans would be too stupid to understand the potential implications

>>15055821
can jwst really detect atmospheres there?

>>15056244
no, i think most humans would be smart enough to realize that some rock 100 light years away is completely irrelevant even if it is habitable

>>15056249
it's one of the primary objectives of the telescrope

>>15056261
can it also check what the composition is?

>>15056274
Yes, as the anon said it's the primary objective.

>>15056274
>>15056275

>>15056274
yes but it'll take more time than WASP-39b, the signatures have a lot more disturbance and are fainter

>>15056276
so if this planet has water and co2 could it be terraformed? we could start growing plants or some sort of biological life

>>15056225
We can't even send a ship with humans to Mars.

>>15056449
its a gas giant so i dont think its feasible here

>>15056227
nope, it's just monks and cheese.

Who gives a fuck? FTL is bound to be a thing eventually dumbass, even if it isn't actually tavelling faster than light.

You people love to humm and haww about muh laws of physics when all physical models just don't function and you guys don't even know shit about dick anyway. If you people had a clue we wouldn't be in this mess. Stop listening to Einstein, he gave us nothing besides confusion.

I'm more looking forward to JWST observing Titan and Europa.

>>15055821
Well they sure lack diversity in there.

>>15055821
Venus has an atmosphere
Mars has an atmosphere
Titan has an atmosphere
even Io has an atmosphere

None of these planetary bodies have life.

>>15056453
We could. They'd just have a real bad time

>>15056476
Use robots.

>>15058727
[citation needed]

>>15056453
That’ll happen before 2050. Only a question of who will do it first: USA, China, or some private entity.

>>15056274
it's kind of a problem for infrared. if we could get a visible spectrum version of the telescope then exoplanet data would be so much cleaner

>>15058727
That we know of.*

>>15055821
>what do we do if we find atmospheres cause that means they could have life
Start broad band monitoring of radio and optical signals from the system.

>>15056482
>not able to use the scientific units?
Where is the problem?

>>15057838
>just monks and cheese
Probably also beer.

Bot posting??

>>15056691
Yeah people seem to just ignore that for some reason.

Any atmosphere those planets may have had will have been blown away by flares and the planets themselves will be tidally locked so while some of the far out ones might have oceans under their ice the rest will be wastelands varying from Venus like to Mars like.

Still an interesting system and worth taking a look at but it almost certain to be shit for life.

He's talking about using space time manipulation to accelerate to sub-light but still very high speeds. You'd avoid the need for exotic matter (maybe) but also avoid the colossal energy expenditure of accelerating a ship to relativistic speed.

>>15056476
Just use boudets like civilized space travellers

>>15061164
What happens if the ships hits even a grain of sand on its journey?

Even if a method is found to get up to those speeds it would be suicide should the ship run into anything while travelling at the greater percentages the of light.

>>15061520
With space warping, that's not a concern. It's been shown that any debris is decelerated once it enters the warp bubble.
Even with actual realistic relativistic speeds, there are ways around it. A thin screen travelling in advance of the ship will ionise any particle it strikes, without major damage to the screen. This ionised debris can then be deflected by magnetic field generators mounted on this ship.

>>15061164
>You'd avoid the need for exotic matter (maybe) but also avoid the colossal energy expenditure of accelerating a ship to relativistic speed.
Even if you acellerate to 0.1 c where relativistic effects are becoming noticeable, the energy expenditure will be absolutely enormous. Or how to you plan to accelerate the spacecraft?

>>15055821
It's pretty unlikely we'll find planets with biosignatures. If we do, we'll slowly be able to calculate the lower bounds of any given star system being able to spontaneously spawn life.

>>15056453
We have the technology but no funding.

>>15055821
we send nukes
we have to secure our position as the only sentient beings in the universe

>>15060800
There's probably outliers where the planet somehow wandered into the star system or habitable zone after the initial hot phase is over but even then sustaining an atmosphere will be a huge uphill battle. If most of the planet's surface is covered in ocean the currents could probably warm up the entire planet which would permit life but anything beyond single-cell lifeforms would be nearly impossible to evolve due to lack of sunlight from massive cloud cover.
Personally, I think the most promising star systems for life are the 0.5-1.5M single star systems.

>>15061761
Nukes aren't strong enough to sterilize all life on any single planet. You need to achieve K2+ asap and then laser the fuck out of every single planet in the local galaxy group that has a biosignature.

>>15056225
>theoretically
you're a fucking fag

>>15061762
Magnetic field is the first requirement to even have atmosphere. At least in the long run. Moon probably also had atmosphere and even flowing water on surface. But not for long. Same as Mars. Planet must have magnetic field to prevent solar wind blowing atmosphere away.

>>15061748
The idea with warp drive spacetimes is that there are no relativistic effects, because you're not "really" moving.. You set up an alcubierre type space time (never mind how), but if you stay below light speed you don't need exotic matter (in some theories).
The energy expenditure comes about BECAUSE of the relativistic effects due to crashing through spacetime like some ape. If you warp space you may not face these problems.

Look up Alcubierre Drive, we can theoretically travel at light speed or faster without breaking any laws of physics.

I hate sci fi so much
Did you guys really get into stem because of science fiction fantasy shit?

>>15063215
... except for the bit about negative mass which is some horse poop.

>>15063237
Only ftl spacetimes have been proven to require negative mass. It may be possible to construct a slightly slower than light but still hyperfast spacetime with only positive energy.

>every plant, animal, and rock formation has a concealed dick.

>>15060800
No they don't you just don't know the full picture.
During their early life this is true, but after a few billion years the flare activity dies off.
And for the rest of multi trillion year life span there's little flare activity.
Means there's plenty of time for life to evolve.

>>15056227
Good that they are 40 light years away from earth. We should send the rest of them there.
