At this point it doesn't even matter if JWST is cancelled or not the ELT is orders of magnitudes more powerful and will be ready by 2025.

So even if JWST launches in 2021 it will be made redundant in just 4 years time.

JWST is powerful enough to detect H2O, CO2 and methane in the atmospheres of exoplanets in a sphere 500 light years around the solar system.

ELT is powerful enough to scan the entire spectrometry of exoplanets up to 30,000 light years away. Which is about 20-30% of the entire milky way galaxy.

ELT will most likely be the first telescope that will detect clear signs of life on another planet (if there is life) and if it doesn't it means that the 30% of the galaxy it has scanned is without life which would most likely mean we are alone in this galaxy.

JWST barely matters anymore but I still hope it launches in 2021 without problems because it can prepare the public mindset to the great search for life the ELT is going to start in 2025.

There's no need for fancy telescopes to know that we are alone in this galaxy. Evidence of them would be overwhelming across the sky and they would even be here already.

Amusingly, UFOs and aliens and other conspiracy theories that says that we don't find aliens because they are actively sabotaging us from seeing them are more plausible than many Fermi Paradox "Solutions".

30% (tens of billions of planets) not having life on it is a large enough sample set to extrapolate over the entire galaxy. Especially as the 30% cone where we scan things will contain all types of stars and exoplanets. It is a large enough sample set to make generalizations about the rest of the galaxy (and most likely the universe)

>> No.11186094

>>11185948
it will still be scanning a very biased set of planets due to the scanning methods, it's perfectly plausible that some of those same biases coincide with factors that lower the probability of abiogenesis

>> No.11186126

>>11186094
The only bias I can think of is the plane having transits from our point of view. That shouldn't affect abiogenesis. What other biases could there be?

>> No.11186156

>>11186126
the first one i can think of that could affect it is that we are detecting proportionately many more quickly orbiting worlds in comparison to ones with orbits farther out, both because of the quicker period and because of the angle window lining up far more easily for such worlds

also the entire premise of detecting life through spectroscopy of the atmosphere leaves me thinking there are many ways life could form on a planet without us detecting such a thing from just the chemical composition of its atmosphere for various reasons, or on the inverse that we could be getting many false positives because we can't really confirm what we are seeing in any way and have to depend on basically almost-speculation using a single type of model we've thought up

We always have proof of one occurrence of life arising in the galaxy.

It'd make life much more interesting, for one. It'd be cool to find carbon-based alien life forms not entirely unlike us, owing to parallel evolution. But also to find aliens that are completely foreign to us. Just as long as they don't want to wipe us out.

>30% (tens of billions of planets) not having life on it is a large enough sample set to extrapolate over the entire galaxy.
This is incredibly wrong. You have no idea of the odds of abiogenesis. Hence you cannot extrapolate from simple percentages. Maybe our galaxy is the odd one out and should have many hundreds of planets with life, but it has only 3 planets with life and ooops we chose the wrong 30% to look for it. Or maybe abiogensis is extremely rare and only 1 galaxy in a billion has life, either scenario is still equally plausible from simply excluding 30%... A very simplistic counterexample that shows we cannot extrapolate from "30%"

>Especially as the 30% cone where we scan things will contain all types of stars and exoplanets. It is a large enough sample set to make generalizations about the rest of the galaxy (and most likely the universe)
>all types
You almost made a valid point but fell short. A heterogeneous mixture of things being scanned means nothing in terms of narrowing down possibilities. However, if we only scanned the top 30% of planets/solar systems most-likely to contain life, and the remaining 70% somehow were concluded to be exponentially less likely to have life, then yes you could extrapolate and make valid subjective (not exactly numerical) statements like "it's very unlikely there is other life in our galaxy". But you never said or implied anything of this sort and this hypothetical would be very difficult to verify.

To qualify what I'm saying, nothing you've said would necessitate a less than 1 in 2 chance of other life existing in the galaxy (we didn't even scan 50%), which is far away from your statement of being "most likely" alone in the galaxy. It could be far far far less, but we don't know from merely scanning the 30%, which again is not even half.
