We don't know about life on other Galaxies.

The signals we have sent haven't cross Milky way yet nor we have tech to zoom in to detect life signs on other galaxies.
signals aren't the only way we could perceive life, activity as well counts and we have yet to see unnatural activity. We make plenty of noise as intelligent life.



Scale of observable universe is 92 Billion light years - diameter.

46 B is just the radius

That makes the scaling more absurd lol

Yeah there are many ways like analysing atmosphere of the planet..

Issue is if I remember well then we haven't discovered a single planet outside our Galaxy yet. They are hard to detect as they don't emit light like stars

Even in milky way we detected just more than 5000 so far out of billions estimated to be in the Milkyway itself.

Yes we do see noises but often it's some error or we find some scientific reasons. Also, these aren't reliable sources as our sky is filled with it unless we see a repeated patterns and in a particular frequency which we haven't.
 
Another thing is that we as humanity can be sure that we will never invent a time machine,ever. Because,if such machine will be created,someone would have go back in our time or a previous time,right? So if nobody ever came back,this means that we as humanity will never create a time machine,not even in the year 3000 or something. Unless in the future there are some laws that forbid people to reveal things. But even if there was such law,is it possible that nobody ever broke them? So i think sadly we can be sure that we as humanity will never invent a time machine to go back in time. Sorry,this comment was more sci-fi than political lol but i posted it because of the alien stuff so it was connected in some way,sorry for the off-topic lol.
Time always move forward - that's why people still wonder about what is time?


funny thing is in theory FTL travel allows for backwards travel

I worded myself wrong there.. it's highly unlikely but not impossible.

Our physics equation due leave room for time to flow backwards but it doesn't align with what we observe - time always flowing forward.


Infact, many believes there is link between time and entropy.

As universe is expanding - it is changing - time denotes this change and out of all the laws we have, there is only one law which prefer time - entropy because it's only entropy which always increases with time - it can never be decreased.

That's why people say "Arrow of time" always move forward.

Also, the scale of the universe - many people don't realise how big universe is when they talk about aliens so easily.


Observable universe is 92Billion light years.

Based on Study of curvature, we think whole universe can only be in 3 possible shapes.

So, we estimated the minimum size of the Universe - whole Universe - and, minimum size is 14 Trillion Light Years...it can wary but you get the idea

that is something that always unsettled me. If the universe is ever expanding, could objects leave our observable universe? Have they done so already and we just don't know? What is outside our observable universe? more universes?

You answered your question


It depends on dark energy and energy density of our Universe.


As of now, due to dark energy universe is expanding with accelerating rate,...if this continues then gradually galaxies which we can see will disappear from our views and then there will be time when we won't be able to see anything. It will be dark...

Infact, if dark energy continues to rise then in distant future even our Milky way will be ripped apart and gradually all the stars, planets and even atoms.

This scenario is referred as big Freeze or Big Rip.


But if dark energy slows down or energy density increases then whole universe might collapse...


As of now, evidences are pointing towards Big Freeze - In trillion years from now apart from local galaxies everything else will disappear from our view point

And, yes outside our universe should be more universe just like what we see in observable Universe...

Perhaps multiverse
 
Having mysteries in the universe and science AS A WHOLE being incomplete doesn't mean you can't have completed work to make some claims.
That's precisely why I tell you some fact like : sex and gender are different things. Because this is something we KNOW.


We had both on time. What is consensus by the way for you? 100% of scientists?
When I'm talking about consensus I'm talking about scientific consensus not regular people.


It doesn't seem so.
Sure :milaugh:


You are the one claiming consensus without having it. And yet I showed you how there is no consensus.
No you didn't .. WTF is wrong with you ? :josad:



I don't have to be a scientist to proof someone else is wrong. Even scientists.
Actually when there is a consensus about something, you need to prove that the consensus is wrong so unless you know a lot of science (and therefore be a scientist) you will be unable to prove the consensus wrong.
Just look at the terminology of the word and you will understand. There is no bigger proof than that. People are just forcing to change the meaning of it now because of woke agenda they can't be real woman or man sexually so they just say their gender is man or woman. If anything they wouldn't have to cut their dicks to change gender if it was different from sex. They doing that already says it is the same. But sure you will woke how they are oppresed to feel that way and do that and blablabla.
1. This doesn't make sence
2. This is on the limit of transphobia


Your self-claim consensus is not consensus. Only heavy extreme leftists wokes like you care about that shit. You are minorities.
Yes it is a consensus... WTF is wrong with you ?
Talk to scientist, because right now you are in plain denial.
Completely unscientific, you are just speaking with your hate and irrationnality.

:endthis:
You said. But as always you are taking back your words and changing them.
No, second time you are trying to lie.


You never "proof" me wrong. You are in plain denial of science.


To destroy the family institution
How exactly ?


Parents would no longer be in power of their children
Wow that's how you see the relationship parent/children ? No wonder you are completely problematic...

You are a red flag.


And ultimately bring back communism by giving all power to stat
What are your sources for saying that ?


What are your sources for saying that ?


What are your sources for saying that ?


rivate property. Self-defense. Economy
Same thing


I don't think this is an insult to you at all. Dude you really think I'm trying to insult you? I'm just pointing what you are and what you are doing and why you behave like that. Because you are woke. And there is no turning back for you. Of course I don't think that is an insult to you. I'm pretty sure you must be proud about how much I brought up your wokeness.
Your are in full moral panic mode...

This is irrelevant to alot of people using other languages than english where this distinction isnt made, you know. . .
This distinction is made in scientific field all over the world.

No lol, you can just make a lot of laws around time traveling, it would be hard also to distinct what was altered by time traveling
