    This is an extremely accurate Dark Matter detector. We are either measuring Earthâ(TM)s distortion as the moon revolves around us, as the solar system revolves around the sun, or as we enter a region of space where we are swimming in dark matter.

    Bravo!

    What "classified" information did the former Secretary of State send from her portable device while walking in fresh air, or cooking up a mess of gumbo for Bill? While it is reasonable every Former President and their First Lady has continuing contacts with heads of other states, these retired public servants are still responsible to positively advocate for America's interests.

    Sometimes a thought out if the blue BECOMES classified after the fact.

    I doubt Hillary took classified information out of a SCIF in her socks like Admiral Poindexter!

    A black hole isn't a purse where you stuff things and are lost forever. They are energetic balloons that feast and starve, and eventually disappear in a pop. I wouldn't be surprised if collapsed super massive black holes would look like the Big Bang.

    I was getting lost in the number of cowards responding to this thread. Thank you for giving a non-Jeckyl/Hyde face to this discussion. Perhaps it is time to infect 1000s of lab monkeys with measles to prove the argument by dissection. The anti-vaccine people would have their proof, and the science would be demonstrated.

  12. Re: It's not the gas... on NFL Asks Columbia University For Help With Deflate-Gate · · Score: 1

    1 Atmosphere (ATM) is approximately 14.7 PSI, which is always the zero-point of an inflated object. You need an additional 12.5 - 13.5 PSI to achieve the proper internal pressure beyond 1 Atmosphere. The ~25 PSI is correct.

  13. Re: A precision deflation on NFL Asks Columbia University For Help With Deflate-Gate · · Score: 1

    Yuck - your math was correct, but let's simplify your answer a bit.

    You started with a pressure of 27.2 PSI at room temperature, and arrived at nearly 26 PSI as the field pressure, with a realized loss of 1.2 PSI. That's an impressive loss, but the other team's footballs would have suffered a similar effect.

    You have my admiration, sir or madam. Well done!

    It's refreshing to watch everybody grapple with the nuances of basic physics principles, only to discover they don't understand them so well.

    1) was the same pressure gauge used for both measurement? If not, who calibrated the precision instruments used by the referees?

    2) 1 ATM = about 14.7 PSI at STP. Where was it the patriots were playing?

    3) 1 ATM = about 14.7 PSI at STP. These balls were inflated to 27.2 PSI with a properly calibrated pressure gauge, otherwise the quarterbacks are grappling flopping pigskins.

    4) height above MSL (mean sea level) also affects the gas chemistry, and gas mixture does drastically impact pressure. Inflating tires with (relatively) inert nitrogen is now all the rage. What if somebody was inspired to use a unconventional mixture?

    It's terrific that people are trying hard to puzzle out the mechanics. Perhaps some trust will come out of this with future climate change discussions.

    That is a beautiful thought. Any of those remote telemetry stations in military bases? Had NASA been in charge of GPS, we wouldn't have destroyed the plans of the original satellites, nor the higher precision add-ons. We are out of spare GPS satellites and a replacement has yet to be launched.

    You like weather forecasts, right? Weather satellites freed fleets of aircraft and ground stations from creating a patchwork image of cloud cover.

    You like television, right? Television programs use to be relayed across the country and compressed so much that the east coast thought Hollywood could only do film and the west coast knew the easterners for the worthless, blurred colorless taped programs. Direct TV wouldn't exist without NASA.

    I wouldn't call the space program "worthless" by any truthful measure!
