Could we walk around on an alien earth like planet without spacesuits? This is assuming the atmosphere is like ours. Or would we suffer allergic reactions to everything and be poisoned by alien pollen?

Pathogens are generally adapted to whatever life is present in their environment, and therefore may have no mechanism for impacting our health. But it's certainly possible that our physiology could be affected in any number of unforeseen ways (e.g. an alien plant may releases microscopic silica particles with sharp protrusions that would tear up our respiratory system).
I wouldn't volunteer to be the first one to walk around without a suit

>>6391246

There's so far no concrete way to know. We would have to find a planet, study it, and try releasing mice, dogs, monkeys etc. and see how they reacted first. My own personal speculation is that there are some planets somewhere in the universe that we would be able to walk on unaided.

Random question unrelated to OP's topic but related to OP's picture. Why are spacesuits white?

>> No.6391292

>>6391279
Reflects heat. Without any dispersion from the atmosphere, direct sunlight would bake an astronaut in a dark spacesuit.
Just off the top of my head. I don't actually know this for a fact.

I doubt pathogens would be a problem but I would be concerned about the aliens being made of some toxic chemicals or something that would cause a reaction.

Of course its speculation, there's no empirical proof of aliens. Doesn't make it an illegitimate question. Calm yo tits

This is /sci/, we follow a different set of rules around here. Speculation, hypothetical, "What if" and other thinking questions are not allowed. We deal only in facts, and absolute facts at that. So get out of here, we don't need your kind to advance the wonders of science.

There is a difference between "extraterrestrial life" and "Muh ancient aliens" you know.

No there isn't. There is no life outside earth. Maybe some shitty single celled automata ten million lightyears away. MAYBE.

Stop being willfully retarded. With the probability of multiple universes you cannot ever claim to know for sure what's out there. So long as people aren't talking about fucking grays living in our solar system (or hell even our own planet) then there is absolutely nothing wrong with speculation and claiming otherwise is the scientific equivalent of being a bible-thumper.

Now, take not at the difference between the previous example and this:

>we have no proof of fire breathing unicorns anywhere
>we have no reason to believe there is a place in which there are fire breathing unicorns
>ergo, it would be unreasonable to speculate on the existence of fire breathing unicorns

Obvious troll.


Also the chance of there being life on another planet is way bigger than that there isn't and we are the only one.

>> No.6391805

>>6391595
The ammount of planets is so high we have no reference of comparing it.

So we just say infinite.


If there is an infinite possibilities, how likely would it be?

That being said: yes there are planets, that are identical to earth.


No there is no way to verify it.

You are exactly correct, OP! It's allergies all the way down! Allergies with radioactivity too!
