Also earth is habitable, good for repairs and cheap fuel. If the mining scenario was plausible then, like kartikg points out, an asteroid field would be very dangerous to navigate. Think about it, you would have to be able to time the power and speed of descent of a craft on an asteroid so it doesn't get smashed then you have to deal with debris that is traveling at high velocity because there is no friction to slow it down. Then you need to get equipment to extract the needed minerals and metals then be able to lift off without being smashed into by other asteroids. A planet is relatively safe, an atmosphere to disintegrate most debris, there is food and water and even places to hunker down in for the night if needed. However our planet and solar system is not unique in any way, most asteroids do seem to contain the metals mentions PLUS even stuff we haven't discovered and identified yet. There are just so many reason why an inter-stellar traveler would not bother mining our asteroid belt, unless they were in the area and it was a real serious emergency (just thinking other scenarios) that there is not enough time in the day to mention them all. 1 Link to comment Share on other sites More sharing options...

Why even mine for it? Just hit the central banks.. Link to comment Share on other sites More sharing options...
psyche101 Posted August 3, 2016 #55 Share Posted August 3, 2016 They wanna get my They wanna get my Gold on the ceiling I ain't blind Just a matter of time Before you steal it It's alright Ain't no blood in my eye 1 Link to comment Share on other sites More sharing options...

The amount of energy and resources that it would take an ET race to travel vast distances makes the mining notion rather silly. Gnomes and leprechaun are more likely suspects than aliens since they are earthlings. LOL Link to comment Share on other sites More sharing options...
aquatus1 Posted August 16, 2016 #60 Share Posted August 16, 2016 I find it difficult to believe an alien race could master intergalactic travel without first having to master molecular reconstruction. Having done that, what would be the point of mining specific resources, if you could mine practically anything and turn it into the element you need?

You don;t have to actually land on it and mine In situ in the the middle of the belt, just clamp an engine on the back, steer it remotely off somewhere quiet like above the plane of the ecliptic or something and pick it apart at leisure. 1 Link to comment Share on other sites More sharing options...
