Food for thoughts.

It is estimated that the Universe is 100 000 light years across so, personally, I think there are thousands of other inhabited planets but so far away that we will never be aware of each other and that makes me feel good, knowing that we are not alone.

If the universe is still expanding, where does the space it is expanding into coming from

There is believed to be creation, existence, call it what you will, beyond th edge of known space.

Me and my friend many years ago used to smoke Moroccan black then just sit there trying to work out where the universe ends and what is the meaning of life. 🤔 We could sit there for hours and obviously not work either out🧐

Sorry, that is not correct.

Our Galaxy is around 100000 light years across. The Universe is far bigger.

The Observable Universe from any given point in space is around 93 billion light years in diameter.

The Universe is far bigger even than this.

There's also a restaurant at the end of the universe if you fancy a cup of tea on the way there.

You need to think of space as an entity in itself. It is expanding very rapidly. It expands into nothingness for want of a better word.

Imagine space as the content of an inflating balloon. Our Universe is contained within this space.

But the balloon has space outside it the balloon is inflating into

Was there no all night garages back then 😁

My son and myself often talk about space....
Its interesting, it's thought-provoking and we talked about life here and the possibility somewhere else?
Watching 'How our Solar System Works' uou realise in the billions of years in its creation, the myriad of circumstances that gave us what we have, such as the theory that Jupiter (I think it was) , early in the systems creation was much closer to the sun and due to its size, probably cleared the space of debris between the sun and beyond Mars. Had it (Jupiter) not been there our planet would have been continually smashed by asteroids etc and life here would have been unlikely
Add in the myriad of other circumstances external and on our planet itself, the chances (imho) of other human like civilisations existing are remote to say the least (again imho)

There.must be life out there...but not as we know it Jim

Glad you corrected me and even more convinced now that there are other inhabited planets in the Universe.

No. You are confusing Space with nothing. The two are totally different.

Space contains visible matter, dark matter, various forms of radiation including dark energy, etc. What we think of as an empty void is far from empty, it is a seething mass of energy, etc.

Outside Space there is a complete absence of anything, ie nothing.

Space is currently expanding into nothingness.

This seems to be the current state of play re our understanding of the cosmos. Or at least it's how I understand some of the broad 'concepts' of large-scale cosmology - I am no cosmologist!

It's worth researching this online.
