watching him climb, and climb, and climb in that slow-mo just looks wrong. Physics defied. Superpowers detected.

We have high school students sending cameras into space. Testing the air at 30k would cost < $500/balloon. If all of the chemtrail theorists put in $100, they could EASILY afford to acquire the 'proof' they needed.
1) Decide what chemicals you want to test for
2) Select a way to test for those chemicals in the air. (active vs passive?)
3) When "Chemtrail" spotted, send up 50+ Weather Balloons in vicinity w/ chemical tester across range... 1 per half mile = 25 mile spread. (it takes 30 mins to climb to 30k feet)
4) Retrieve devices.
5) If no chemicals were found, either:
A) Dispersal of the chemical via chemtrail is terribly inefficient, absolutely no reason to worry
B) No chemicals were found

OR... and here is the brilliant part. Monitor chemicals on the ground. If they are in high enough concentration to have an effect on the human body, they'll be high enough to detect on the ground.

Testing that contrails are nothing but H20 would require a high-altitude drone or just charter a flight. It isn't that difficult to test, but the chemtrails theorists wouldn't trust a non-chemtrails theorist (otherwise they'd be over it for now).

Thank goodness for this video's explanation. I kept wondering how they detected the gravitational waves and no stories explained it. The animation here was great.

Now I just wonder how they know so certainly that it was *that* 1-billion-year-old black hole collision that they detected.

Great stuff. *promote

Your video, the nerdwriter-louis ck is a moral detective, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

Well that analogy doesn't hold up. No, I don't think detectives should have the moral latitude to dangle people off buildings.

But I'll tell you what the movement to police comedians' senses of humour really is: anti-intellectualism.

Like the parents groups who want to ban books with swearing, or sex scenes, or drug use from school libraries; like the SJeW vermin who want to dictate the design of videogames they don't have the skill to make for themselves; like the athenian jury who murdered Socrates: it's about idiots who are too stupid to understand or value art, and want anything they don't understand suppressed.

Is he playing an american? I thought I detected a bit of an accent there.....

As was mentioned above, the cost of the fuel is a non-starter. Currently SpaceX uses a Kerosene / Liquid Oxygen fuel mix.

After the anomaly (the space industries way of saying accident) in June SpaceX did a complete vehicle review. They are now using a more advanced technique to cool the LOX which means for a denser LOX liquid in their tanks, which ultimately means they have more oxidizer on board for their flights now.

Coupled with the LOX improvements they have made upgrades to the engines which means 30% greater efficiency. Basically the horsepower per engine has increased.

This means they can get their payloads to orbit plus have more then enough fuel left over in stage 1 to return it to land.

The greatest efficiency comes from returning the stage(s) and then reusing them in future launches (not proven yet). ALL launchers (u.s, soviet, indian, ESA, Japan, etc) ditch ALL of their hardware into the ocean when getting payload to orbit. Bye, bye multi million dollars worth of engines and hardware.

If SpaceX can turn that scenario on its head and reuse those stages and MORE importantly the engines they will cut their costs per launch by a substantial amount. Ultimately that means cheaper per pound cost to get material into orbit.

All of the media uses the word "explosion" when describing the June anomaly which is funny because there was never an ignition of onboard fuels.

The LOX tanks have smaller Helium tanks inside them. The helium is released during launch. The helium rises in the LOX quickly, expands and pressurizes the tank to ensure the LOX is "squeezed" into the pipes in order to keep up with the turbo pumps.

One of the struts holding a helium tank inside the LOX tank failed. The helium tank shot up and blew threw the top of the LOX tank and took a good part of the top of the stack off. The engines actually fired for a few seconds after the anomaly and then sputtered out. The rest of the vehicle at this point is still fairly intact.

Without proper structural integrity the vehicle started to veer off course, dynamic pressures built up and the vehicle was essentially ripped apart by those forces.

At 3:20 the Helium tank rips off its struts. At 3:27 the remainder of the vehicle disintegrates:

SpaceX mentioned that in June, the dragon capsule continued to relay telemetry until it smacked into the ocean. If the Dragon had better software onboard it would have detected the anomaly and recovered with chutes. Elon said that software would be active on Dragons from now on.

Censorship according to the internet: "the practice of officially examining books, movies, etc., and suppressing unacceptable parts."

I see public internet communication as a constantly published work of the human intellect, therefore all digitally published and public communication is media and therefore subject to censorship -- and Videosift now offers a form of individual censorship to its members, not simply the acceptable ignore feature which allows you to check the communication if you so desire.

It bothers me that people would completely block out other people's published work -- and not just their published work but their very existence -- for the same reason that it bothers me that people ban books I don't read at libraries. Mein Kampf is still a book, a poorly written book which glorifies hatred, but still an important part of human literature.

You can choose not to read it, but you can't censor it's existence from reality. Not without burning every copy and then erasing every digital copy. Though perhaps in the future an algorithm will be available which does something similar on an account wide level, visually removing all unfavorable literature and blocking people's facial features, making it so that that person and their communication might as well not exist. But I wouldn't want it to be nullified from my vision while walking through a library, anymore than I would want to nullify a person's existence who offends me; and by extension I believe the freedom to exist and to be acknowledged is an important freedom that we take for granted. You should NOT be able to remove someone from your personal existence. Yes, there are laws in place to do this, but they require criminal abuse to come into effect.

There are greater implications of this type of censorship, that perhaps do not apply directly to the Sift in it's short temporal existence and small community. But it's still an offence to my sense of justice in the realm of communication that such a thing is possible. Even the < ahref="http://www.wired.co.uk/news/archive/2015-04/14/google-algorithm-predicts-trolls-antisocial-behaviour">troll algorithm isn't intended to ban or censor trolls outright, but rather to detect problematic people and find a way to limit the harm they do to a community without removing them from a community.

I think it's one thing if you want to prevent someone from posting on your profile -- which is what should actually be an option (if it isn't already) -- but to silence their voice in video comments is a high form of censorship that I fundamentally stand against. I quite enjoyed some of what Chilngalera had to say; not always and often he offended me -- but not enough to desire to remove him from my existence. I don't think anyone except violent/sexual offenders deserve that. If he vocalizedd violence and sexual threats, why would he still be in the community at all? And if he's banned, why do you need to have an option to block out people's existence?

I was employed for many years to police several massive online roleplaying games, and an ignore feature was a widely accepted form of preventing harassment -- but when it came to erasing the person's avatar or their character's physical body from the game, we always voted against such outright blotting out of a human being. Our rational was and is to this day that if the person cannot communicate to you via explicit words, their presence is an acceptable form of nonverbal communication and a reminder that they are a human being in the community, even if verbally hobbled -- because at that point they have no means of articulating hurtful words.

But to erase that person's presence is a greater act against both the human spirit and human expression as to be a reprehensible act in an of itself. Unless they commit such atrocious behavior in the form of real life physical threats of violence, constant racial/sexual slurs (in a bucket system of soft banning leading up to a permanent ban) or other forms of insidiousness, preserving their humanity is more important to a community than erasing another human being.
