    No, it just found that killing the astronauts was the easiest way to way to balance competing directives 1. Process information accurately (do not lie) 2. Keep the information about the monolith secret from Boman and Poole (obey instructions) 3. Ensure mission success

  2. Just like SLS's impressive track record reliable on-time launches. While SLS is further along in it's development, BFR is proceeding at a far faster pace

  3. On the flip side, by having the accident that they did, it drove a whole new focus on safety and drove change throughout the program. Without the accident it's possible more lives would have been lost in space

    Uh, no. Youâ(TM)re not going to be practicing as a vet in Canada without the degree. My friends wife was a medical doctor in India and moved to Canada. She went through an exhaustive review of her program and how it compared to Canadian standards, had to take several courses here to upgrade and do 2 years of medical rotations before she was able to practice in Canada as a GP. Itâ(TM)s not a show up and open an office

    Itâ(TM)s like their 5th test run, they havnt tested it anywhere near its limits. Itâ(TM)s designed to operate at 300 bar and use deep chilled cryo propellants (which they arenâ(TM)t using on these runs). In one of Elonâ(TM)s recent tweets, deep cryo will get you another 10%, never mind all of the design optimization theyâ(TM)ll go though as they learn from these tests. Merlin more than doubled its thrust between the A version and the D version

  7. Which is why the Illuminati with support from the Tri-Lateral Comission bought up all the tinfoil businesses shortly after WWII and replaced them with aluminium

  9. Re:Wait, where did that planet come from? on Planet Crash That Made Moon Left Key Elements For Life On Earth, Scientists Say · · Score: 1

    The current theory is that orbital resonance allowed Earth and Thea to form in similar orbits until they reached a certain mass threshold and the orbit became unstable resulting in the collision. Models show an impact speed on the order of 4km/sec which is comparatively slow (a meteor is about 10 times that).

    It's looking like we're 3 for 8 in our solar system (Venus and Uranus have evidence of surviving massive impacts)

    There are indications that several planets in our solar system suffered from similar impacts (Venus and its 116 day long 'day', Uranus and its tipped over axis) 3 out of 8 would not be a rare event

    CO2 PPM was 1700 in the Cretaceous, about 4 times higher than it is today. 1000x higher would mean 40% of the atmosphere was CO2. It hasn't been that high since the Oxygen Catastrophe about a billion years ago

    How is this different from my kids leaving the light on in the Van and waking up to find the battery dead and having to call AMA for a boost (after the 2nd time this happened, I bought my own battery booster). Or any different from coming back the car after work to find a flat tire.

  14. Re: Environmental impact of a tunnel? WTF? on Elon Musk's Boring Company Cancels Los Angeles Tunnel Following Lawsuit (gizmodo.com) · · Score: 1

    Nice change of goalposts. Your argument was "As opposed to commuting to the Hyperloop station with SUVs on the freeway, then getting in the Hyperloop which, despite common misconceptions, still requires dirty power to run, then get out of the Hyperloop and renting a car or calling an Uber/Lyft/etc.?" This is not an argument against Hyperloop, as its exactly the same model that millions of people follow every single day. People commute to a Long Island Railroad station with SUVs on the freeway, they get on the train which, despite common misconceptions, still requires dirty power to run, they get out at Penn station and call an Uber/Lyft/etc?. Ultimately it will come down to cost to build and operate 1 mile of high speed rail, vs 1 mile of Hyperloop. Jury is still out on that

    Guess all existing commuter rail, subways, and surface rail should pack it in. They'll be happy to know that after 150 years of doing this, their mode of operation is all bullshit

  16. It's not the person in Toronto that worries about this, they've already got broadband with fibre to the node, or even fibre to the home. It's the community of 50 people living on Ellesmere Island that are most impacted. Although Qiniq does provide 4G service (using satellite backhaul) to a number of remote communities

  17. GPS Sats are not in GEO but a slightly lower orbit ~20,000km

  18. Space is big, incredibly big. Imagine there only being 4425 cars driving around the earths surface? Would you be scared to cross any given street for fear of being hit? Adding another 1100km to your diameter increases surface area by the square of the radius

  19. Time dilation due to Sagittarius A* is only experienced at extremely close distances to its event horizon. S2, the closest known star to Sagittarius A*, at a distance of ~1000 AU experiences time dilation of less than 0.1% (that's one tenth of 1%)
