Comment: TERCOM (Score 1) 11

The first implementations of the SLAM-type algorithms came from a missile with the same name; the Supersonic Low Altitude Missile. This was a multi-attack nuclear weapon which would cruise along the ground at Mach 3 and pop off nukes on Russian cities as it went, spewing fission products from its exhaust. A truly monstrous weapon.

Its design started in 1955. - No, that's not a typo.

Comment: Re:How about we beta test on Venus? (Score 1) 367

The CO2 in Venus' atmosphere could be used as a source of carbon for building a ribbon around the planet. A satellite-based atmospheric heater could perhaps propel the gas to sufficient altitude. The oxygen could be combined with hydrogen so that vapor clouds formed on Venus, since those reflect a lot of sunlight back into the atmosphere. There might be enough hydrogen in the solar wind for this to be done reasonably quickly.

It could be sensible to build an orbital ring/space station around Venus while we wait for the planet to cool...

Quite glad to see that Mars doesn't get all the Terraforming attention! =)

If it had mass, presumably yes. This of course assumes the new universe has the same laws of physics as ours.

They might not have the same laws of physics. In that case, they would fit the strict definition of 'dark matter', even if not the actual observation which caused the term to be invented.

This shims another layer of abstraction in between the causa prima and the now.

To be specifc, it makes sense for logical entities not to play outside the rules of axiomatic set theory. Axiomtic set theory is defined and limited by this assumption which in turn creates the very fabric by which we do math. - You make up a rule and then you follow it to its logical conclusion.

Are humans logical entities? A lot of our existence is determined by the evolution of our neurons, which gives rise to an inherit body of knowledge that we call instinct. We know that life is an emergent property of physics, so it does indeed make sense to question wheter or not this is a silly place.

I don't attempt to tell you what's what, but merely to tell you that the pure math approach isn't it. GÃdel proved it, BTW.

The math probably is new. The current discussion certainly involves new participants.

Interest in the matter at hand traces back to before the dawn of modern man. The philosophers of Ancient Greece wrote about chaos and logos.

There is a wide community of thinkers who are well-versed in all of these narratives. You're welcome to join us.

Not a silly question...

It's important to distinguish the anthropic concept of three dimensions plus time-in-one-direction from cosmology. If we don't do that we just attempt to shape the universe in our own image. A whole lot of philosophy needs to be skipped over for the cosmological universe of discourse to make sense.

There's a simple cheat to better intuit the fabric from which the quantum fluctuation emerged, called the anthropic principle. - Whatever fabric needed to exist did exist and still exists because if it didn't we would not be here to observe it. It's an existential proof.

The anthropic principle isn't as useless as it might appear at first glance. - It allows for new universes to fluctuate into existence at any time.

My pet theory is that such a parallel universe in 3D space is what caused the oh-my-god particle event. =)
