I don't think it's that strong a chance tbh. The six kingdoms will probably still be there. They'll be different, but probably recognisable.

lived in australia for a few years. isolation breeds monsters i tell you

Chances are the life will either:
1) Look exactly the same (see convergent evolution)
2) Operate similarly (see panspermia)
3) Be completely foreign

3 is by far the least likely.

As it mostly depends on the conditions that said life is produced from, and the conditions of the planet it's on, I'd say a mix of 2 and 3.

While Oxygen and Water based environments would probably (as far as we know) be the easiest to host life, due to their relatively volatile and reactive nature, they aren't the only possible base for life, as many extremophile bacteria and fungi we find around our own planet can provide examples for.

In places that have little to no light to photosynthesize, you could find plants that feed off tidal heat, (as seen in the sea floors by hydrothermal vents) or even creatures that feed off of high energy electromagnetic rays like x-rays or gamma rays (as seen in the fungus that grows in Chernobyl's reactor core)

They could also be ammonia based, sulfur, or silicon based, since any of those could be catalysts in a multitude of energy-bearing reactions that can sustain life. (and we see several types of life here that utilize those different reactions) Our own carbon/water/oxy based life is dominant mostly because of the open availability of said substances, our planet has to be a very specific temperature to be able to keep all of them in a stable, usable form.

However, traits such as orifices to eat and waste, reactive organs to light, vibration, temperature, and/or physical touch, (most of those being in pairs or greater to maximize physical awareness) and limbs or other attachments of some sort to manipulate and move through the surrounding environment would be fairly universal, so we'd possibly see ET life take shape in ways that we could compare to our own, even if it functions by completely different methods.

Convergent evolution, do you not understand it? For instance, whatever reason plants are green for would likely make other "sun-eating" lifeforms also green. Everything has the same chemicals to work with.
Chances are animals won't have two heads, because that's twice the sensory weak spot.
Chances are they'll have eyes that work in roughly the same wavelengths as earth creatures: red through to ultraviolet, as these wavelengths are common to less intense stars like ours.

But all this is under the assumption that the particular alien life survives on the same things most life on earth do: light and oxygen.


While what you're saying is true, 1 and 2 is only more likely for similar lifeforms, similar conditions. Why do the aliens need to have any legs, or eyes, or heads?

Well they're going to use light, it allows life forms to find prey and avoid being eaten.

"Animal" style life would need legs to go after its prey, legs work very well on rough terrain unlike the alternatives.
Heads are really just sensory nodes, if you put all the sensors on the front you can detect **** in front of you. Plus it's good to have them closer to the central processor. If life evolved in an underground ocean like on Io they might not use eyes but they would definitely still have heads.

Yes, those were just examples, other traits may also be carried over, too numerous to list.

8 legs are more "expensive" to maintain.

evolution is the product of "survival of the fittest" which means the traits that make it fit in with its environment are carried on. So if life was in a completely different environment then surely the life-forms would be different from our environment.

Different, yes, but they would likely use the same solution to some problems. "fish" looking organisms work no matter where you are.

EVERYTHING WILL BE ON A COB

>if we find other planets
You mean when we get there.

im fairly sure if they find life on Jupiter's moon, (the one with a mile of ice over top and liquid water underneath, and a hot core and what not) it will pretty much be almost exactly the same as what we have in the depths of out oceans, it would be in the exact same conditions and environment.
i wouldnt be surprised if, when they get a probe there and under water they have pics of yeti crabs and those tube worm things.
folks will think its just a hoax

Warp drives aren't nearly as far fetched as they once were, we've recently accidentally created warp bubbles with electron drives, and space travel technology of the similar persuasion is looking bright.

Warp speed doesnt go faster than light, it covers a distance faster than light can, but its not moving faster, if that makes sense.

Can't I be an optimist?
What do you make of the reports from NASA of instances of warp bubbles in controlled settings?

The confined "Bubble" for lack of a better term, undergoing warp and travelling, its something to do with the space in front convexing and space behind concaving, creating a bubble in stasis. And with regards to space not being able to be warped, Im pretty sure a black hole is an instance of space being warped

Can you blame them? I guess im a hopeless optimist for interstellar travel

All we need is a way to travel faster than light, then we're fine. That, or massive 'moving colony' type ships with their own gravity and places to grow food.. So, another 100 years for the second option to be possible, maybe.
Pity I won't be around to see it.

Nice roll

That's a pretty good roll once you find out what this is from.

ayyy lmao.
