I can't decide if Brennan is stupid, or if he thinks everyone else is stupid.
That's an inclusive-OR, isn't it. I.E. Brennan is that stupid, and he thinks everyone else is stupid enough to swallow this line.
Didn't the German state invest some money in paying for development of GPG a few years ago? So shouldn't the German Ambassador be creating a diplomatic incident out of this?
That should allow allow them to make the drive much more efficient.
You have some reason to think that this is not already working at maximum efficiency? It's natural efficiency may be low - like the efficiency of the conversion process of potassium nuclei plus an electron into argon nuclei.
When I hear the word "location" in a discussion where quantum effects are almost certainly present, I always start looking for Heisenberg's location under Schrodinger's cat.
I remember giving myself a headache one month trying to work out what would happen in the last moments of the evaporation of a black hole, by Hawking radiation. At some point, the size of the remaining black hole is going to be so small that the blackhole is smaller than the wavelength of the particle/anti-particle pairs it needs to emit... which... makes... my... head... hurt. Will the black hole be able to radiate in that energy range, or will it stop radiating? Beyond my physics. And maths. But I do get very cautious about non-classical concepts of "location".
Ohhh, you've mangled the history of plate tectonics severely there. Final out come is about right, but there re some severe slews in the intervening path.
You've missed out Alexander Du Toit, though mentioned his work on Gondwana fossil distributions and glaciations. He also added the mantle convection idea, though that was greatly clarified and improved by Holmes.
The 1955 "turn up at a conference" was by a couple of geophysicists who'd been publishing their results for several years by then. Started 1952, I think.
The consensus was still "vigorous argument" well into the 1960s. And details are still being worked on to this day - the terrane / microplate concept is still being argued to this day, though more about "which generates more testable hypotheses" than about which is "true", since both are to some degree true.

I wasn't particularly keen on the result of the vote either, but unlike you I have actually read the fucking technical articles and decided that I'accept their reasoning as valid. I'd still prefer to take the "self-gravitated spheroid" definition, but that would still run into the same problem of needing to differentiate between planets and satellites, and leave us with 13-14 planets in 1978 (when Charon was discovered and the Pluto-Charon system accurately weighed). (That's your desired nine, plus Ceres, Vesta, Pallas (possibly also Hygiea, is 530Ã--407Ã--370km "nearly spherical"?) and almost certainly Chiron (it's light curve was close to flat).
I'm pretty sure we've had this conversation before. If you want your preferences to count, feel free to build a career as an astronomer or planetary scientist and get a vote. (BTW, I'm probably a lot closer to getting a vote - I'm working on being voted into a chartered astronomical society. And I won't be voting the way you appear to want to.)
Which was a few parts per million iridium - compared to the parts per billion in the Earth's surface rocks (on average). About 60% by weight oxygen, 10% each of magnesium, silicon and iron ; the remaining 88 elements making up the 10% balance.
killing the dinosaurs
I hear dinosaurs singing in the trees most days. They don't sound very extinct to me.
... well, the one that made the Yucatan bay).
It landed about on the edge of the Yucatan peninsula - the impact hypocentre being a little in from the coast. But that's like talking about "New York, New York" 10000 years before the start of the Pleistocene glaciations. The presence of the modern coastline is pretty much coincidence (the part-circle of onshore cenotes is less coincidental).
If that is in fact true (never dug into it)
The Chicxulub Coring project of th IODP finished drilling at 1339m MD a couple of weeks ago. The core is in progress to onshore laboratories for examination. See http://www.eso.ecord.org/exped...
or you can surround it with a bunch of ablative shielding (like how regular space capsules return to earth), maybe using some kind of cheap material that's also mined up there.
That's the general idea. But remember that the majority (99%+) of rock fragments that hit the Earth's atmosphere turn to rubble before they hit the stratosphere (20-50km up)... you're going to have to invest some engineering and machining into that "ablative structure".
Not a show stopper - just another cost involved in returning material to Earth's surface. So most of the time, you wouldn't do that.
(unless you send a really huge chunk and accept the fact that much of it will burn up in the atmosphere and you'll have to dig up the rest from the impact crater).
Stuff that impacts from interplanetary orbital velocities doesn't stay in the impact crater. The kintic energy that is released on impact vapourises the material (be it rock, or iron, or... well tungsten might survive, but gold has melting and boiling points around two-thirds that of iron) in the impactor and you only find small fragments of the impactor scattered miles around.
You'd be better landing it as flying crowbars - with the front 20m being disposable iron and the last couple of metres being the interesting material. Each one would land with the energy of a small (WW2 era) nuke. Enjoy finding a landing site. (Incidentally, this is a plausible interplanetary weapon. you might encounter political push back.)
most helium is just vented from nat gas wells, wasted
Your technique for extracting helium from natural gas is... ?
You do realise that where it is economically feasible for current techniques to extract, separate and store the helium, they do that. And where it isn't economically feasible, they don't.
For what it's worth, of the 14 economically feasible gas field discoveries that I've worked on, not one had helium concentrations greater than "below measurable". They do try to measure it - because it's potentially valuable, and geologically interesting (where the fuck did this helium come from??) - but only a small proportion of gas wells have significant helium.
We have the technologies or mining asteroids. We don't have the technologies for drilling beyond about 15km TVD (True Vertical Depth - not the same as MD, Measured Depth. I've drilled wells to 20km MD, they're just not vertical).
You might be able to shade that 15km by a couple more km in areas of low geothermal gradient.
I am very dubious about that claim too. I have (I think) 8 fillings, up to 37 or 38 years old, and I've never had a filling fail on me. Not one is of gold. In short, non-gold fillings are perfectly adequate.
OP may have had an incompetent dentist, who did his fillings so as to guarantee a return visit within a decade. That would e a shockingly unheard-of situation.
If I remember correctly, asteroids on average have several times the rare-Earth mineral concentration as Earth.
That may be true, The concentration may be tens of parts per billion, instead of singles of parts per billion. Meanwhile, in those few locations on Earth where geological processes have concentrated the REEs, then you're up towards whole percent of mined rock (that's tens of millions of parts per billion, on the same scale).
Yes. That's the point.
How long is the period of time you're considering. Is it a year, a decade, a lifetime, a civilisation's lifetime (half to one millennium, on past performance) a species lifetime (100kyr to 1Myr), a planet's lifetime?
There is around a 1% probability that Earth and one of the other inner planets will collide before the Sun turns red giant. Time scales matter.

Actually, you may have a point there.

Having no rest mass (because they are never at rest) is not the same as having no momentum. Photons have momentum.
