Beyond Imagination

The visual effects department are already putting together various scenes (I showed you a little taster yesterday) and will continue working for many months after filming has finished. I’ve seen several different sequences, most of them are still pretty rough, all of them are seriously cool. I’m hoping that Tom will sneak me some more to show you soon.

I think one of the more tricky bits of animation will be when we get close to the Sun. The spaceship’s shield has a diameter of 1.449 kilometres (I just asked the visual effects guys to measure it exactly for me), but let’s say 1.5 kilometres. That’s massive by Earth standards, but quite frankly puny when out in space. How, exactly, do you represent the size of the Sun, which has a diameter over 100 times that of the Earth’s, when the spaceship gets near it?

Get out your tape measure.

OK, 1 metre represents the Sun’s diameter. 1 centimetre represents the Earth’s diameter… The Earth’s actual diameter is 12,756.3 kilometres. The spaceship’s, as I said, is 1.5 kilometres… try and imagine 1/8500th of a centimetre ( 1 x 12756 ÷ 1.5= 8504)… Actually, go look at this. I’ve made a blue image 8,504 pixels wide and right in the middle I put a little one pixel square dot of yellow. Try and find it. That’s how big the spaceship’s diameter is compared to the Earth’s.

Now in this one, the yellow bit is the sun, the blue bit is the Earth. Everyone you know and everyone you don’t know, all the people falling in love, all the babies being born, all the people dying, all the music, every painting, book and film fits onto that dot.


The Sun is awesome beyond imagination… and the animators are going to have to imagine it.

I’ve got hold of some of the videos they are using as reference…

I’ve just been told that some of the graphics that have been made for the on-board computers have been changed from green to blue. I’ve got some copies of the old graphics for you to look at. You won’t be seeing these in the film. Apparently ‘green’ was too much like ‘The Matrix’.

Supernova School

Today, Dr. Brian Cox came in to talk to the actors about the Universe. He started out with the Carl Sagan-esque question ‘What are we made of?’, went on to speak about the elements and explained how Iron, atomic number 26, is the heaviest element which can be made in the heart of stars. Everything in you- the oxygen, the carbon, the iron which makes your blood red- was made in the heart of a star.

Any element that is heavier than Iron and lighter than Uranium- silver and gold, for example- can only be made in Supernovae, the violently explosive death of a star. He told them how a supernova shines as brightly as all the stars in the galaxy for several months then slowly fades, cools, and becomes a nebula which in turn gives birth to a new star…

Several supernova explosions have been seen over the years. One of the earliest on record is the Crab Nebula.

The ancient Chinese, Japanese and the Anasazi (the Ancient Puebloans) of America left records documenting their sighting of the star that died in a supernova explosion and created the Crab Nebula.


Though it was 6000 light years away from Earth, when it exploded it shone in our sky as brightly as the crescent Moon.

Betelgeuse in the constellation Orion is about to die. It is a red supergiant which many astronomers believe will go supernova within the next 1,000 years. It could go tomorrow. Though Betelgeuse is only 15 times more massive than our Sun, it is as much as 40 million times greater in volume; that means if our Sun was a soccer ball, Betelgeuse would be Wembley Stadium in London. Betelgeuse is only 500 light years away from Earth. As a supernova shines as brightly as all the stars in the galaxy for several months after it explodes, when Betelgeuse goes, we will have two suns for a few months.

I think the actors’ minds were blown… let’s just hope there’s enough left for them to remember their lines.
