The concept of space absolutely fascinates and bends my head in equal measure. The film interstellar did a good job of both explaining a lot to me in idiot terms and giving me a ton of further questions that are so expansive I don't know which one to ask first
What do you mean by "nothing"? If its nothing then how the f*** do you expand into it?
As @c4fcdenmark pointed out. Very hard to comprehend given that we and all around us is matter. It might be worth reading the other link I posted at the start. For me, I believe in the multiverse theory. We are one of numerous universes that exist but do not interact (most of the time) with one another. Particles of matter that are extremely hard to detect pop into existence from time to time, such as the pentaquark in that article. I believe that it is those particles that make up dark matter/dark energy that exist in another universe, and how we came to be in existence in the first place. I'm no scientist so could be factually completely wrong, but this is what I have picked up from reading articles etc, watching tv programmes. As I've mentioned previously, scale and our size, limits what we can get our heads round.
Here are some links if you want it better explained
Eric Idle explains it well - 'I mean, what do you have to lose You come from nothing You go back to nothing What have you lost, nothing'.
Within the "boundaries" of the universe, there is both matter (stars, planets, gasses, and so forth), and space (what is in between the matter). But beyond the boundaries of the universe. What's out there, and how do we describe its location and time? Since there are no reference points outside of what we know, location and time cannot be described. Indeed, we can't even ask the question "where (or when) is it?" because any possible answer would be meaningless.
Those links were interesting cabbles and the first time I have heard any of this stuff explained in vaguely comprehensible terms. Are you a physics teacher by any chance?

No, but I have a passion for it. I think the hardest part is that to truly understand it, you need to have a mathematical background, as it is all just numbers. Also, the ideas and the concepts they talk about can stretch my non mathematical brain to such a point that it becomes almost philosophical.
I certainly don't have a consistent and deep enough knowledge to go into detail or explain it clearly
We can only explain what we know and we don't know more than we know. HAving said that, it is amazing how much we have found out in the last 100 years.
The 3 billion miles thing amazed me but for me its all about finding the next earth. One of the best documentaries I ever watched was a "what if" on if the earth found out it would be consumed by a star in 75 years and how we would get off the planet etc.
Everything we seem to do in space is in the possibility of finding the next earth. As interesting as it is to know our solar system... We won't be going there on holiday (or out of necessity) a few hundred years from now

Mathematicians have calculated it is highly likely there is life (has been or will be) on other planets, but just as likely we will never know about it. If life or evidence of there once being life on a planet like Mars is found or on another planet, it will prove almost to the point of certainty that life is abundant in the right conditions. We then think about intelligent life. We would like there to be intelligent life. What is the point of all of our achievements if nobody knows about them. I’m sure a sheep in a field doesn’t think – those humans are a clever lot. Insects could claim – if they had any interest in doing so – which they don’t – that they have been far more successful than humans as they were here before us, there are more of them and they are likely to be still here after us. Even dogs can claim they left the earth’s atmosphere before humans. The more you learn about space the more you realise how unimportant we all are!

Pretty much this.
If it's expanding into something then that something is part of the universe - as universe means 'everything'.
But what about dark matter? Isn't that there in the space where there is apparently "nothing"? And anyway, what is "nothing"? I mean, you could say the spaces between subatomic particles is "nothing".

You are correct. Dust, gas and cosmic radiation all exist in space. There is never truly nothing in the true sense of the word, but space is particles so far apart that nothing in the looser sense of the word can exist.

One of the links was to a TED talks.
TED is probably the best thing on the internet, you should spend some time clicking around the website, watching videos.

I can also recommend cosmos a space time odyssey on nat geographic. Superbly produced and easy to follow. Neil de Grasse hosts. Episode 9 is particularly good. Talks about extinction and discusses how stupid humans are in how we are destroying the planet. Hits home

I completely agree. I am 99.99% sure there is life on other planets. Anyone that says that there isn't is ignorant. One thing that always annoys me though is how they say "there is no water on x" or "there is no oxygen therefore life couldn't survive" surely that goes against the very concept of evolution? Why couldn't life survive on nitrogen or other elements for example? I feel like often our imagination is limited by human constraints.

His theory is very interesting in that it says for intelligent life to exist and us to know about it, they would have to harbour/harvest all the energy in their galaxy as a means of transportation given the vast distances.
You are spot on when you talk of life existing on other elements etc, you only have to look at the bottom of our oceans where there is no light and organisms live off nitrogen sulphide

Thanks I will definitely read that. Already read up on the concept of dyson trees by freeman dyson.
Didn't they also find bacteria that live in arsenic pools? I find it perplexing that we talk about the possibility of life on planets with gravitational fields which are insane in comparison to ours and would require an exoskeleton stronger than titanium but I always hear the things about lack of oxygen etc making a place uninhabitable.
In the show I watched they used nuclear bombs dropped behind the rocket ship which would explode, with the explosion being captured by a concrete dome which was the bottom of the ship which would then propel it.

I think it's crazy the amount of power required to break through the earth's atmosphere, but once free the probe utilised the gravitational pull and throw of Jupiter to reach ridiculous speeds. The engineering in all this is incredible
I think the two biggest problems to making any significant journey are the phenomenal times is would take (New Horizons was travelling at over 36,000mph and still took 9½ years to reach Pluto) and the fact that you couldn't (at least with present technology) build anything that would have the power to escape another planet's atmosphere to return.
