Quote from: Oshyan on July 18, 2012, 01:40:09 pmSome incredible work there, very good sense of (massive) scale in many of them. Most look like straight "hand" painting, some with photo composite elements. A few do look like 3D renders though...This one is particularly unusual and interesting. Not necessarily realistic, but it certainly makes you wonder what's going on...- Oshyan

QuoteEvery animation or image I have ever seen of planets colliding has shown them coming together like a couple of pool balls hitting each other practically head on, resulting in a colossal display of fireworks. Surly it would be more likely that given most planets result from the concretion of the stellar disk of material (think a massive amorphous version of Saturn's rings slowly condensing into individual planets), all the planets would be travelling in the same direction and at roughly the same speed. That would mean that planets would gradually be pulled towards each other over many millennia as their orbital paths become closer and closer and only actually "meeting" relatively gently. Of course by gentle I do mean massively destructive tidal and gravitational forces and huge electro magnetic disturbances due to the combining of two electromagnetic fields. It would be massively destructive but not in the way always shown on TV docs. It would be interesting to visualise with some decent simulation software but I doubt the result would be the "impacts" as shown on TV.CheersRichard
Quote from: Tangled-Universe on July 20, 2012, 02:47:33 amThose meteorites are a lot lighter than the huge planet-like rocks in the images. Meteorites will be easily accelarated like you describe (gravitational sling) but large bodies will accelarate considerably slower due to their huge mass.

QuoteIn the end you're still right; Imagine two celestial bodies hitting eachother because their outer circumference of their orbit just slightly slightly overlapped. It's not a head on collission, more side by side, but both their speed is great already.
