Absolutely stunning. The distances involved are mind-boggling.

Space isn't really my thing - once you realise how vast the distances are, it is hard to comprehend it all. And also, I'll never go there. I don't even really know whats bigger -a galaxy? A universe? What's the milky way? How does that fit in?
Is there a useful kind of map or chart that visually demonstrates all these things to highlight what TBG and Gofer rightly say above about how small and insignificant etc we are?
You don't know if a galaxy or a universe is bigger?
Nope. I'd guess universe?
As a young kid, I used to imagine sitting on the moon and looking at Earth and knowing that people had different languages, customs and religions depending on when and where they were born on this planet. That attempt at an overview has never left me but I didn't have any concept of just how tiny our speck of dust is in respect of the firmament as a whole - and let's not imagine that this speck of dust will be habitable ad infinitum.
There was a clue: "and it's estimated that there are trillions of galaxies in the universe."
Would suggest starting here (and especially the last line):

do you mean metric or imperial galaxies?
Some studies suggest there's likely to be at least a septillion stars in the universe, let alone planets which would on average raise the figure by a billion or two! So it's quite possible there may be at least 10^27 planets in the visible universe. Of course the other parts of the universe we can never see will contain an awful lot more. This is the chief reason I don't believe in the Rare Earth hypothesis.
I missed that bit cos my brain just processed it as someone rabbiting on about space again.. which is probably how I got in this mess.
I enjoyed the film gravity and made lego space ships as a kid but thats as far as I get with space.
Saw this the other day, which was a bit of an eyeopener

You cannot be Sirius!
To be fair, Cadbury never made a 'Universe' chocolate bar so it's impossible to compare really.
So your general knowledge about space is limited to confectionary!? I give you Mars, Milky Way and Toblerone (spot the odd one out).
Toblerone? It's not in the Aero?So your general knowledge about space is limited to confectionary!? I give you Mars, Milky Way and Toblerone (spot the odd one out).
Definitely in the right Orbit but I'd say you'd have to throw Starburst into the Starmix too.

Something you aren’t an expert in or have an opinion on.
Never thought I’d see the day!
Ha ha, you're beating me. I've given up eating sweets now in an effort to lose weight lol. I don't want to be totally weightless though. That might be a massive mistake.
The University of Leicester has scored another hit - first inventing DNA and now this.
They invented DNA?

I think you must know what I meant but, as you probably know, genetic fingerprinting is the correct term.
