Watching the Mars thing tonight, what an achievement, actually seeing images from a far flung planet.

Now it kinda made me think, what really is out there ? ok mars is pretty close in the scheme of things but further away out there, do you think there is life out there else where or are we really just a quirk, something elemental happened and somehow it developed into life over the years, we missed all the life extinction events and are a unique occurrence, and the rest of the universe is just barren lifeless..

Or is there other life out there.

what do you think ? we are alone, or not....

If space is indeed infinite then I’d like to believe there are other life forms out there ... what they are though is anybodies guess!

Here’s how I look at it.

You sit in your living room. Look up, you can see the ceiling. Stand on your sofa and you can probably touch your ceiling. You know and can prove that there is a physical barrier just above your head.

Now go and stand outside, look up. There is no ceiling. That space above you, it’s infinite, (as far as we can tell).

I’d say it’s a certainty that somewhere out there are other life forms. Whether those other life forms are simple bacteria, plant based, aquatic, semi-intelligent mammals, or super advanced aliens is hard to say, but I’d say the chances of us being alone in this universe is pretty much 0%.

I have always assumed if the universe is as big as we think then odds are there are other life forms. Though they could have litetally evolved and died out millions of years before us.

How do you define life really.

Intelligent life? Who knows? It’ll be incredibly rare in any case as the amount of ‘ducks in a row’ that have to in place for intelligent life to evolve and prosper are astronomical.

Basic life like bacteria or even plant life? Probably quite common throughout the universe in my humble opinion.

If space is infinite then there will absolutely be life out there as every combination of particles will be repeated an infinite amount of times, even if its just other versions of ourselves

if space is infinite then there are infinite earths etc.

Humans with our monkeys brains just cannot fathom how infinite works.

Saying that i think we will never find any other lifeform due to the distances required and most like die out before we ever really make any progress, due yo monkey brains.

In 1999 they had found/estimated 125billion galaxies
In 2013 they had increased this to 225billion
By 2016 they had revised this to 2 trillion.

Now in our Galaxy alone (not a particularly big galaxy more small to small medium) we have 100 thousand million stars.
And then the number of planets in our galaxy is beyond 100 billion (add again for number of moons).

So 2 trillion x 100 thousand million stars (suns) x 100 billion planets gives you a possible steer on the number of planets.

We could then take an educated guess of how many planets are on the goldielock zone as a % of the total and then it’s anyone’s guess if they have had life yet to start life do have life.

Then why assume that life can only exist in conditions that we believe support life? Life could be in so many places we wouldn’t even consider.

Or were in a Petri dish and it’s all one big experiment. And those watching the experiment are themselves too in another petridish.

Maybe there is a god maybe not maybe god is a higher species maybe not.

Maybe it’s all a dream.
Maybe covid 19 era is simply a nightmare and sooner or later I’m waking up and life is as it was.

But what if they find us? "To Serve Man", the Twilight Zone.

Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.

Arthur C. Clarke

The problem is that when it comes to finding other life forms E=MC2 has got us beat before we even start, the nearest star apart from the sun is something like 4.24 light years away.

Think about that for a minute...

Four and a quarter years travelling at the speed of light to get to the nearest star and probes that were sent into space 40+yrs ago have yet to leave the solar system.

I've no doubt there's intelligent life out there but I very much doubt we, the human race will ever encounter it.

population of the universe: none.

It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is zero, and that any people you may meet from time to time are merely the products of a deranged imagination.

One of the many strange things that keeps me laying awake at night is that if something can be infinitely big, it can also be infinitely small (Men In Black marbles scene zooming out through the galaxies) then I think that maybe religion isn't such a wacky idea after all... So yes to answer your question, it's impossible for there not to be aliens.

No one knows if there is an infinite amount of space

Given the size of the universe it would be quite incredible if there is no other life out there but, given the size of the universe, it would be quite incredible for us to ever find it.

Complex life that is, simple life I would not be surprised to find out is all over the place including several spots in are own solar system.

For sure there is little men with big slimy heads out there, hmm maybe I'm thinking of the last PH meet I went to.

That’s debatable. Not by someone with my tiny brain, mind.

There is most certainly life out there, quite likely there is or was basic life elsewhere in the universe. Intelligent life is another matter, but there are more planets out there then there are grains of sand on this planet. If one in a billion can sustain intelligent life, then there will be a lot of it.

As said before, the odds of them finding us or us finding them them is so vanishingly small it will almost certainly not happen in our lifetimes, probably unlikely to happen in our species' lifetime.
