I suppose it's not impossible for a large lizard-like beast to develop an ability to spray a two part hypergolic (self igniting) substance to give it...
Sorry it took so long to answer your question, didnt see it until now, my value estimate earlier was way low, asteriod details: Asteroid 3554 Amun...
Actually, I do have a serious question on the subject, what is the distance in light years where out TV and radio signals attenuate into...
Er, if I understand what you're asking.. If the atoms comprising humans vibrated at a higher frequency what you'd be talking to is a sentient plasma...
Well, from here you can't really see the center, too much gas and dust in the way, you can see a bit in the infrared and radio spectums though and...
I think the problem with Mars is that its gravity is just too low to hold on to enough atmosphere to provide enough pressure over long periods of...
To be fair, there have been proposals to harness the solar wind by means of a "sail" which are large 6 to 8 mile wide mylar mirrors which would...
I remember reading somewhere we owe our moon two big debts of gratitude; 1. It gave us large daily tides thus prompting evolution of terrestrial...
Good post Pete! Something I've always been curious about, why does light slow down in matter thus leading to refraction. Without having any real...
Ah, that answers that, after a bit more googling it turns out that pure salt is not a conductor. Okay why are things reflective then?
This might be a little lower than the usual grist of this forum but I got to wondering about transparency, specifically why is any matter...
Going to mars doesnt actually do much for us other than some planetary science, R & D for the trip there and back, and publicity. The moon is...
Thanks, I'll take a look at it
Arrgh, to use the word radiation is misleading, its Electromagnetic Radiation, NOT nuclear radiation (no high energy neutrons or protons flying...
RF energy is non-ionizing, which means it does not strip electrons from atoms and thus drive chemical reactions. At the absolute most it increases...
I believe that there is an iron mine in Canada which is mining just such an ancient impactor. At any rate, the biggest reason the Earth doesnt...
PS, try to bring your iceballs in on a minimum velocity trajectory, like using the sun's gravitational frame dragging to slow them down (a reverse of...
IMO only Mars and Venus are candidates for terraforming, Mars is quickest, you'd need to bring in 6 or 7 iceball Kuiper Belt objects of at least 400...
Good grief, this thread brings up many a fond summer memory I remember that as soon as I was old enough to hold a magnifying glass I fried ants...
I've got a better idea, lets use self-replicating nano-assemblers that use carbon from the air to build diamond structures for humans. Think about...
Separate names with a comma.
