I think you mean the anthropic principle. It doesn't state that the Universe "tweaked" its laws for intelligent life to exist, as if this is some active on-going process. It just means that we can only exist in a Universe in which the laws of physics allow us to exist.
Would such an universe be left extremely vulnerable to few mad men who could destroy intelligent life at the touch of buttons or some cosmic phenomena destroying intelligent life on the only planet?
Absolutely, why not? The laws of physics allowed us to evolve, and those same laws of physics allow us to be wiped out by an asteroid, a nuclear war, a gamma ray burst, or a plague (man-made or otherwise). They are not mutually exclusive scenarios.
This assumes both objects are of the same mass, both are traveling at the same speed, that the collision is perfectly elastic, that one object transfers 100% of it's momentum into the other (i.e. it is motionless after the collision), and that none of the momentum is transferred into rotational motion.
That is a lot of assumptions even accepting the premise that 2 objects collide perpendicularly, with both objects traveling at orbital speeds, which is pretty unlikely. I guess if two objects with a 90deg inclination between them crossed orbits at exactly the same time.
I don't agree with blanket statements applied to any group, whether a culture, religion, county, political party, what-have-you...
The difference between the statements "those commie bastards" and "those election-hacking Russians" is pretty stark, especially in scope. Those "commie bastards" was intended to instill mistrust in anyone who was communist, associated with communists, etc. Now, 30 years ago, if someone had said "the KGB is spying on us" would you treat that statement with the same disdain?
Do you think that the ISRO launched these for free? They nearly tripled the previous record of the number of satellites in a single launch. It was probably, by far, the cheapest per-satellite launch cost ever. This will potentially have a huge net-benefit for the Indian economy, as other countries and companies flock to them for future launches.
Also, something not noted in TFS (but in TFA): these satellites were launched into a polar orbit, which requires significantly more delta-v, due to the fact that you can't use the momentum from the Earth's rotation to your benefit.
I'd be curious to see the worst case of how much delta-v can be induced into a piece of debris during a collision. Are we talking a apogee change of 1km? 10km? 100km? Even if we assume that 100% of the momentum shift is along the prograde vector..
We're not far from the Kessler Syndrome. I don't mind a launch that delivers one or five good 1-ton satellites. But the hundreds of cubesats give me creeps.
Since Kessler Syndrome is based on the exponential growth of the number of collisions (and the positive feedback loop of collisions -> debris -> more collisions), it doesn't really matter how many more satellites we put up there. Eventually, we'll end up in effectively the same place. Kessler syndrome is bound to happen, it's just a matter of when and whether we can effectively deal with it. The only caveat is if we can manage to come up with some kind of effective garbage collection method.
The problem is with the word "crush". The silicon is stuck to the polymer, so when it expands it gets pulled apart, not crushed:
The expandable polymer expands much more and causes sufficient tension in the thin silicon — which is sitting on top of the polymer — so it simply crumples and then breaks.
This is pretty much what happens when IC's undergo thermal failure. The silicon, epoxy, copper, etc. expand at different rates, and since they are bonded together, the chip eventually rips itself apart.
I do agree that while it might be effective at making the IC non-functional, it's doubtful whether the information within can be destroyed reliably this way.
I imagine that most of these vehicles have undergone extensive testing on closed courses before they are put on public roads. Also, there is someone in the car while it is being tested, ready to take over if necessary.
IIRC, the only times that Google's self-driving cars have been in an accident is when the operator took over control.
Well if you really want to get pedantic, then no capturing is 'really' permanent because of the Second Law of Thermodynamics.
But, if we don't want to get pedantic, then any relatively stable chemical state we can convert the CO2 into would still be capturing it. The coal the carbon was originally part of was such a state.
So the number 1 reason you carry a gun is because of taxes? Do you just show up at the IRS once a year and flash your sidearm at them instead of filing your return?
If not, you should give it a try, it just might work! Tax season is right around the corner...
Hear hear! I'd even go further to say that Wikipedia is the single greatest endeavor in the history of humankind: To make freely available the sum total of human knowledge to anyone, and allow anyone to contribute to that knowledge. In my humble opinion, nothing else beats that.

Look, I'm really just trying to cling to anything remotely positive coming out of Washington. Thanks for ruining this one for me.
The pun I don't mind at all.
This bill sets out clear rules to make sure our laws keep up with the times.
Glad to hear we're implementing that new-fangled 4th amendment I keep hearing about.

This is not a pissing contest.

And you couldn't monitor Foxconn from the ground, with say, binoculars or something?
It's fine to use alternative facts, as long as they come from an alternate reality.
Must be a trade union for psychics:
The labor group says the results of the two-year pilot program will fail to sway its opposition to [Universal Basic Income]
Good thing they warned the Finnish government before they wasted time and money on that pilot program.

Doesn't the ability to drive to Vegas for the weekend facilitate commerce?

Guess which gas gets produced when baking soda reacts with an acid?
If the carbon dioxide is prevented from entering the atmosphere, it has been captured in any meaningful sense of the word.

since 2007 (thanks Obama)
Thanks subtraction.

So what you're saying is we should put Trump on the $100 bill?
Just like "raaaaacist!!!" and "sexist", Democrats have been spouting that fear-mongering crap for decades.
So you're perfectly fine with unilateral disarmament and a significant reduction of the defense budget, right? Right?

I'm using an ad blocker and it works fine.
Well they're planning to legalize weed (one of our current PM's election promises) so it's not all bad. :D
It is incredible that anyone is still sending SMS in 2016.
I dunno what you mean, I receive spam/scam messages all the time!
