Hello from someone incredibly interested in science, and yet totally unqualified in any scienctific field; so please excuse this post if it seems like the writings of a crazy person.
I'm writing a short film (I study BA Photography, but am purely very interested in film making in my spare time) and, whilst it's actually just background-goings-on in the film (if you can believe that), my idea is based on the end of the world. I'm not making The Core 2 (Return of The Core?) though; don't worry.
Space has always been something that facinated me, and through that I've been up til very very late some nights reading all sorts. One of my favourite and most read websites, and it might be one known here, it Exit Mundi (http://www.exitmundi.nl/exitmundi.htm). End of the World Scenarios; but written in an incredably good way. If you didn't know it; it's well worth a read!
(I get to the point about now!)
One "scenario" that has got me going is that of a black hole visiting the solar system, but only enough to knock Earth out of orbit. It's only briefly touched upon on the website.
When I watch a film I like to know that it's not based on make-believe, and whilst this is just a no-budget student film - it'd be nice to at least base the events on what would actually happen.
So! Is it correct to think that if something with as much mass as a black hole were to visit the solar system; there would be a chance it could knock the Earth out of orbit, and send it off into space?
And Very Happy If this were to happen; what would be the consequences for Earth? Obviously "not very good" but what would actually happen? It would get colder? Darker? Would the atmosphere thin out?
Be awesome to hear from somebody on this; gosh you could even claim "Scientific Advisor" on my little credits bit Very Happy

MOved from Cosmolgy, this is pure fiction.
Firstly, a black hole passing the solar system at the right speed and direction probably could disturb the earth enough to knock it out of orbit. If the sun dissappeared then the earth's atmosphere would cool at around 1 deg / hour (as it does at night) this would keep going, the attmosphere would freeze into thin layre of liquid nitrogen after about 1 week. You could survive for some time only if you were deep underground sealed from the planet's surface - until the oxygen arn out. Life would not be extinguished though, some single cell organisms could live on for millions of years. I suspect 90% of humanity would freeze to death in about 4 days and the rest a few minutes later. |

I'm not too sure what you mean by that.. as you go on to answer my question
Thankyou anyway
(Also - the temperature drop at night is very interesting! Not only in reference to my post, but it's just something I wasn't aware of! In a situation of the planet slowly being moved away from the Sun, saying in this case that the sun is still there at least, would the drop in temperature be quite noticable straight away? Or would we need to start supassing the orbits of other planets?) |
