A Short History of Nearly Everything: Space

"Now, the first thing you are likely to realize is that space is extremely well named and rather dismayingly uneventful.   Our solar system may be the liveliest thing for trillions of miles, but all the visible stuff in it - the Sun, the planets and their moons, the billion or so tumbling rocks of the asteroid belt, comets and other miscellaneous drifting detritus - fills less than a trillionth of the available space.   You also quickly realize that none of the maps you have ever seen of the solar system was drawn remotely to scale.   Most schoolroom charts show the planets coming one after the other at neighbourly intervals - the outer giants actually cast shadows over each other in many illustrations - but this is a necessary deceit to get them all on the same bit of paper.   Neptune in reality isn't just a little bit beyond Jupiter, it's way beyond Jupiter - five times further from Jupiter than Jupiter is from us, so far out that it receives only 3 per cent as much sunlight as Jupiter.

Such are the distances, in fact, that it isn't possible, in any practical terms, to draw the solar system to scale.   Even if you added lots of fold-out pages to your textbooks or used a really long sheet of poster paper, you wouldn't come close.   On a diagram of the solar system to scale, with the Earth reduced to about the diameter of a pea, Jupiter would be over 300 metres away and Pluto would be two and a half kilometres away (and about the size of a bacterium, so you wouldn't be able to see it anyway).   On the same scale, Proxima Centauri, our nearest star, would be 16,000 kilometres away.   Even if you shrank down everything so that Jupiter was as small as the full stop at the end of this sentence, and Pluto was no bigger than a molecule, Pluto would still be over 10 metres away.  

So the solar system is really quite enormous.   By the time we reach Pluto, we have come so far that the Sun - our dear, warm, skin-tanning, life -giving Sun - has shrunk to the size of a pinhead.   It is little more than a bright star.   In such a lonely void you can begin to understand how even the most significant objects - Pluto's moon, for example -  have escaped attention.   In this respect, Pluto has hardly been alone.   Until the Voyager expeditions, Neptune was thought to have two moons; Voyager found six more.   When I was a boy, the solar system was thought to contain thirty moons.   The total is now at least ninety, about a third of which have been found in just the last ten years.   The point to remember, of course, when considering the universe at large is that we don't actually know what's in our own solar system.  

Now the other thing you will notice as we speed past Pluto is that we are speeding past Pluto.   If you check your itinerary, you will see that this is a trip to the edge of our solar system, and I'm afraid we're not there yet.   Pluto may be the last object marked on schoolroom charts, but the solar system doesn't end there.   In fact, it isn't even close to ending there.   We won't get to the solar system's edge until we have passed through the Oort cloud, a vast celestial realm of drifting comets, and we won't reach the Oort cloud for another - I'm so sorry about this - ten thousand years.   Far from marking the edge of the solar system, as those schoolroom maps so cavalierly imply, Pluto is barely one-fifty-thousandth of the way."


A bit out of date now, of course, but still pretty cool.   Science!  :D

Food and Drink: Delicious Teas

In tonight's post I thought I'd share with you some of the delicious teas I've discovered lately.  The first one was brought back from China for me by my flat mate.   It came in a sort of cake form, wrapped in paper and sitting in a beautiful little box.  

Not really knowing what I was meant to do with it, I resorted to scraping the cake with a knife to loosen enough tea for a cup.   It makes a tasty and very delicate green tea.   Yum! 





Next is a brilliant tea I found in a local tea (and antiques) shop called Anteaques.   When I went I promised myself myself I wouldn't end up leaving with a bad of whatever tea I ordered.  Not only did I fail at that resolution, I also finished the bag of tea within two weeks and had to go back for a second.   It's called Festive Fruits.   It's a hibiscus based tea and tastes just like Christmas!   It's all apples, cinnamon, cherries and almonds.   Delicious!   Quite possibly my favorite ever tea!

This next tea is also a hibiscus based one, and came from a tea shop in London.   It's called summer pudding and is also yummy!   It's full of apples and blackberries and tastes just like an English summer day.

This last tea is one that you can find fairly easily.   It's made by a brand called Tea Pigs, which is quite expensive, but worth it, in my opinion.   I've tried a few Tea Pigs teas and my favorite is one called Super Fruit.   It's another hibiscus based tea (are you noticing a pattern here?) and is full of cranberries and blueberries.   It's got a pretty refreshing and delicate flavour and is yummy! 

Songs/Promotion: Nothing is Easy

This is a song called Nothing is Easy by VerseChorusVerse.   As well as being a lovely wee song, it also happens to have a music video filmed by my very clever little brother!  It was nominated for a Limelight award and everything.   *Proud sister face*.

Photography: Lago Maggiore

I love storm lighting.   You know the kind I mean.   Dark and moody clouds but with the sun still managing to sneak through somehow, casting a strange yellow glow over everything.   The kind of light that can last for mere seconds and when it does appear you of course never have a camera with you.   Well, I was lucky enough to be in the right place at the right time with the right equipment on this occasion, and I managed to get some lovely shots of Lago Maggiore at home just before a storm broke.   Some of them are HDR and some aren't.

Songs: Indian Summer

Who could argue with a bit of Stereophonics?   Everybody knows them, everybody likes them and they just keep getting better and better.   This is Indian Summer.   It's a great song with a vast talent for getting stuck in your head.
