I think we are quibbling on the definition of universe and time. The difference being you say relativity says all of the universe has been acted on by gravity, whereas I say relativity states all of the universe will be acted on by gravity given enough time (e.g. that we lack proof that the entire universe is only as large as the universe we can observe and cannot make statements about the parts we cannot observe).
If you are trying to be pedantic, you would have done better to say that I should have said "net zero gravity." We would still likely fight over whether that means zero gravity. I would maintain that gravity is defined by relativity as the gradient of the curvature of space. And there do exist points with zero curved space gradient.
No, relativity describes the effect of gravity, not the size of the universe or the distribution of mass within. In fact, relativity predicts that if a point in the universe is far enough away from any mass, the effect of gravity has not reached it yet. Thus the effect of gravity is not as Newton described.
Not only did you get both parts wrong, they contradict each other.
All of the points in the observable universe have a mass within range, but there isn't a restriction saying that the universe isn't bigger than what we can observe. And Newton's description of gravity still doesn't hold (due to relativity).
I was intrigued until it mentioned the 7-day battery life. Maybe that could be offset by a quick charge cycle (fast enough to charge while I'm in the shower).
By comparison, I've had regular watches go a couple years on a single battery.
Thanks. The information provided is more hype than substance. I gave up looking for the catch. I'd assumed it was going to be the cartridges holding the materials... just like ink jet printers.

Having actually researched the treaty in question many years ago, let me clarify a few things. The treaty has an out clause. No penalties. Just give due notice, wait a year, and the treaty is void. Nearly every apartment lease is tougher to get out of.
It also permits a limited ABM system. Both sides deployed them.
The treaty had limitations on radar deployment that were obsolete. Every wonder why we don't have a centralized radar system for commercial aircraft? Because we weren't allowed to build one. Inertial means now we're stuck with crap.
I wonder if anyone has ever converted an old refrigerator into a server closet. Sealed from dust and moisture. Sound dampening. And cool. To hell with thermal efficiency or cost effectiveness. Or ease of use.
It'll be a touch windscreen. No steering wheel, no gas, no brake, no turn indicators, cruise controls, no radio/CD knobs, no door handles, no door locks, no side window controls.
With everyone scrabbling at their windows, you won't be able to tell if they are trying to drive, trying to turn on the radio, or trying to escape.

Ok, so you are saying that there is no reference frame in which a point with zero curvature exists?
Or are you saying that no point exists for which curvature is zero in all reference frames?
One would seem untrue. The other reaching pretty far to prove a point.

Yes, there are points with zero gravity. Find 2 large masses near each other. There should exist a point near L1 that has absolute zero gravity.
I don't know how many of you have been to Germany, but it has a nighttime too.
Yeah, they should have corrected to 940lbs.
(hint: gravity ain't zero at the space station)

Being a Dallas Cowboy fan is a choice. And a piss poor one that is tantamount to death.
No, banks were still permitted into speculative markets. Or into retail banking. But not both.
That's a simplification. But the effect was to prevent banks from gambling with other peoples money.

We got the criminals too. Why do you think they started shipping them to Australia?

Maybe not, but they have a new one. From Wikipedia:
9 May 2012 - Crashes during a demonstration flight in Indonesia. No survivors were found.
10 May 2012 - Pakistan is interested in purchasing 8 new SSJ-100 planes.

I'm reading Slashdot while waiting for my Replicator to finish printing parts for a client in China.
I'm curious about the new Cubify from 3D Systems. Could be interesting

Fortunately the software has color correction. All traces of white can be easily eliminated.
Oh, I didn't disagree. It was the foaming-at-the-mouth rhetoric that amused me.
And thank you for the thoughtful analysis. Well stated.

Inspiration is where you look for it.
The whole WWII think was made up? Damn! I knew Granddad told some whoppers, but I swallowed that one hook, line, and sinker.
Pearl Harbor, Bataan (my great-uncle must have faked his death), Nazi's, and Holocaust were all imaginary. Go figure.
Next you're going to tell me the Great Depression was fake too.

Detecting then not working on biological stuff would be good. Intense ultrasound kills cells. Ok, apoptosis (the cells commit suicide).
