Freefall

Before filming on ‘Sunshine’ started over one year ago now, director Danny Boyle was keen to give the eight actors a taste of what it would be like to be a real team of astronauts.

As we join the film, these characters have been together for many years- both on their mission in space and previously in training on Earth- and Danny wanted to make sure that when filming started the actors operated as a team. He also wanted to school them in science and sci-fi as well as give them some real flight experience.

All eight actors lived together in one house. They spent 24 hours a day with one another in order to fast track their team bonding. They all learned to SCUBA dive and did some underwater training to give them an idea of what it feels like to float and be forced to move slowly in the way you would do in space. They each learned to fly a plane on a £15 million flight simulator. And they were each taken up, individually, in a plane to experience Zero Gravity. It worked. Within weeks they really were thinking like the crew of the Icarus II.

We’ve got a new video showing each of the actors’ reactions to being in Zero G.

Sunshine Science

I’ve put up an interview with Dr. Brian Cox, ‘Sunshine’s’ Science Advisor at the end of this post. His job on ‘Sunshine’ involved discussing the science of the film with Danny Boyle and Alex Garland well before the script was completed in order to make sure that the concepts and terminology used were correct. The interview explains how the Sun could die prematurely.

The following was put together by Alex Garland after many discussions with Dr. Brian Cox. It explains, very simply, the background science in ‘Sunshine’.

Q: WHAT IS WRONG WITH THE SUN?

A: A Q Ball is eating the Sun from the inside out.

Q: WHAT’S A Q BALL?

A Q Ball is a super-symmetric nucleus, produced in the early Universe. That is to say, a nucleus made up of super-symmetric particles, formed shortly after the Big Bang.

Q: WHAT ARE SUPER-SYMMETRIC PARTICLES?

They are the super-symmetric counterpart to ordinary matter.

Q: WHAT IS ORDINARY MATTER?

Ordinary matter is what makes us up. Ordinary matter is constructed of atoms. The nucleus of an atom is constructed of protons and neutrons. Protons and neutrons are, in turn, composed of quarks.

Q: WHAT ARE QUARKS?

Quarks are elementary particles. Protons and neutrons are each composed of three quarks. The super-symmetric counterpart of a quark is a squark, and the Q Ball is composed of squarks.

Q: WHY IS THE Q BALL SO DANGEROUS TO THE SUN?

The protons and neutrons of ordinary matter would ‘rather’ be squarks. When ordinary matter is placed in close proximity to a Q Ball, the protons and neutrons are disrupted, ripped apart, and turned into squarks.

In other words, a Q Ball turns ordinary matter into itself. And unless it was stopped, this process would eat the Sun from the inside out, until a critical mass had been reached, at which point the Sun would explode.

Q: ARE SUPER-SYMMETRIC PARTICLES AND Q BALLS REAL?

This question should be answered by work that will be undertaken at CERN, the world’s largest particle physics laboratory, which has its headquarters in Geneva. In 2007, scientists will use the laboratory’s vast particle accelerator to search for super-symmetric particles. It is considered very likely that they will find them.

Q: IF Q BALLS EXIST, DO THE REALLY DESTROY STARS?

It is speculated that the origin of gamma-ray bursts may be the cataclysmic destruction of neutron stars by precisely this method. Gamma-rays are the most energetic form of light, and are produced by events such as supernova explosions.

Q: HOW WILL THE ICARUS MISSION STOP THE Q BALL FROM DESTROYING THE SUN?

The Icarus mission carries a Stellar Bomb, which it will detonate in the Sun. The bomb will destroy the Q Ball.

Q: HOW WILL THE STELLAR BOMB DESTROY THE Q BALL?

The bomb creates the same super-heated conditions in which the Q Ball was made. To be specific, Q Balls were formed at a particular time after the Big Bang: 10 to minus 35 seconds. The heat at this moment of the Big Bang was 10 to the power of 32 degrees.

By recreating these conditions, the Q Ball will split up, separating it into squarks. Squarks on their own decay quickly into normal or stable (benign) supersymmetric particles. Put simply, the Stellar Bomb makes the Q Ball fall to bits.

Q: WHAT IS THE STELLAR BOMB MADE OF?

Dark matter and Uranium. In the same way that an atomic bomb uses normal explosives to trigger uranium into a nuclear explosion, the stellar bomb uses uranium to trigger the dark matter.

In the film Sunshine, mankind has been able to construct two of these Stellar Bombs. The fact that the Stellar Bomb uses uranium is the reason that mankind is limited to only two payloads – because Earth does not contain enough uranium to build a third.

Q: WHAT IS DARK MATTER?

We don’t know, but we have considerable gravitational evidence that it exists. Simply put, the gravitational effects that we can observe in the Universe require much more matter than we can see. Because we can’t see this hidden matter, it has been termed ‘dark’. Dark matter might make up as much as 95% of the Universe.

It is widely speculated what dark matter actually is. Planets, dim stars, neutrinos, exotic particles, and weakly interacting massive particles. But Q Balls are a good candidate.

Q: ARE THERE ANY CAVEATS ABOUT THE SCIENTIFIC BACKGROUND TO THE FILM?

There are, not least because the film assumes that large areas of theoretical physics are correct. In addition, the Sun may not actually be dense enough to stop a Q Ball, but for the purposes of the film, we assume it is. Also, the rate of ‘eating’ is proportionate to the density of Sun – so the rate might be very slow.

There. You can all stop arguing about the premise of ‘Sunshine’ now and get back to the important discussion: are they ‘zombies’ or are they ‘infected’? ;)

Cillian Murphy

For those of you who may have missed it, the other week a new photo of Cillian Murphy from ‘Sunshine’ was premiered at Cillian Online, the Cillian Murphy fan site.

In the comments, Gina asked if I could put it up here. Her wish is my command. :)

Sunshine Video

Yes. Yes. Yes. Yes. The day has finally arrived. I can finally give you your first look at Sunshine.

My colleagues Phil and Damien interviewed Danny Boyle a while back. A bit later on, they took a video camera into the edit and pressed record while the editors were viewing scenes. Then Damien took the interview and the sneaky edit suite footage and cut it all together using music by the fabulous Digitonal. After a bit of persuading, Danny and Producer Andrew Macdonald agreed to let me put it up.

So please make sure you thank Danny, Andrew, Phil and Damien for this beauty: ‘Danny Boyle introduces Sunshine‘.

Enjoy!
