It is a mistake to theorize before one has data. Insensibly, one begins to twists facts to suit theories instead of theories to fit facts.

50%
they either exist or they don't

We exist, so aliens exist. Done. The fact that life on earth exists shows the chance of life developing is greater than 0%, so there are infinite inhabited planets in an infinite universe.

Not an argument. Something with a greater chance of occurring than zero occurs an infinite amount of times given infinite chances. Provide counterpoints or I win and all you’ve done is post a meme picture.

We don’t know that the universe is infinite

Universe: 1
Galaxy: 1

Is it just me or is /sci/ as a whole really bad at discussing probability

>>9782201
Just the fact that it happened once doesn't mean that it has more than 0% probability. Look into measure theory in probability and the notion of a null measure set.

Also, keep in mind that modern physical cosmology usually assumes the universe to be finite.

Not an argument.

>>9782290
We don’t know that the universe is finite. That wouldn’t make any sense anyway, since there’s nothing “beyond” the universe.

>>9782283
There is a greater than 0% chance that every A will have B on it. There are infinire As, so there are infinite As with Bs on them.

>>9782320
Something has greater than zero probability if it ever happens.

>>9782320
No it doesn’t. The observable universe is finite, and that’s the only one ever really relevant.

Dude, shut the fuck up.

>>9782337
I win. You lose. Not my problem you don’t understand basic things. :-)

Congratulations.

You're not making any effort to understand what I'm saying. You may not be stupid, but you're intellectually in bad faith and essentially hopeless.

If your next post shows any inclination to listen to me, I will give explanations as complete as I can give for all the points I've brought up. If you don't, I won't waste any more time.

>>9782375
Sounds like trash to me but if you have some explanation then provide it

>>9782314
/sci/ is bad at discussing everything because the amount of posters that know a given subject will always be smaller than the ones that do not know.

>>9782107
-yes
-no
50% is the probability that aliens exist in this universe

The absence of evidence is not evidence of absence.

believe it or not NASA and other certain agencies have been covering up UFO sightings for the better part of a century

the lid will be blown open once space tourism takes flight

>>9782107
the earth is a sample size of one, and we haven't traveled to any other intrisically habitable planets really yet. there is not enough data to form any sort of statistic brainlet

There just has to be that person pretending to be a retarded “know-it-all” because they know it will get them (you)’s from all the annoyed intellectuals
