It was a little Porpoise-less, none the less I'm incredibly impressed that the got a 727 into low earth orbit and into space!

They should have done it with rocks, not ping pong balls, if they wanted to make an impression.

were the bags really needed during flight?

The bags are reusable if there are no holes in it...

They ARE flying in the 'Vomit Comet'....

Well that just let me know that the price of getting on a zero-G flight would not be worth it.

They are in an airplane in the atmosphere. Free fall =/= zero gravity.

That wasn't zero gravity; that was accelerating towards local COM at 1g.

Zero-G is the ability to achieve the sensation of weightlessness according to Wikipedia. To the best of my knowledge, no other definition can exist in the universe.

Does going into free fall somehow flatten the curvature of space-time around you? Because, unless my understanding of general relativity is way off (which it very well could be), that's basically what gravity was to Einstein. :p

Came here to make pedantic comments, but I see that's been pretty well covered.

The best part of that is the guy in the background you can hear say "Owwwwwe! Give us some warning!" right after dropping 5 ft. into his hip.

You can see the shiat-eating grin on the guy with the camera who knew *exactly* what was about to happen.

The downward force of gravity on each of the 2000 ping pong balls stays constant throughout the video. Neither gravity nor the mass of the balls change. The normal force is what changes.

Kind of. You're following a geodesic that is locally flat (Minkowsi space).

That was a pretty shiatty parabola. You'd think they'd have electronic controls or something that can fly the thing with perfect zero-G.

Also nice of my company to sponsor something like this.

By your reasoning there is no such thing as 0G because everything which orbits about another thing is always in free fall, just moving fast enough to miss whatever it's orbiting. So, astronauts on the ISS aren't really in 0G, they're just in free fall and keep missing the ground. Hence, even if you were out in the middle of a void between galactic filaments you'd still not have 0G because you'd be in free fall towards whichever galaxy happens to be close enough and massive enough to effect you even the tiniest bit over the rest.

You dumbasses. There is a big difference between g and G, so there is a big difference between zero g and zero G.

Exactly. What a stupid argument in this thread.

Wulfman: You dumbasses. There is a big difference between g and G, so there is a big difference between zero g and zero G.


Yes, if G was zero there would be no gravity anywhere in the universe. However, no one in this thread seems to be making that claim.

Actually, when they talk about zero G, that's exactly the claim they seem to be making. I mean, if a motherfarker wants to get pedantic about zero G, then by all means let's get pedantic.
 
2012-12-15 04:00:35 PM
Well then I have no idea what non-pedantic point you were trying to make about g and G.

revrendjim: Well then I have no idea what non-pedantic point you were trying to make about g and G.


I wasn't trying to be non-pedantic. Previous posters had started in on free fall, zero gravity, normal force, etc. My point was only that if they want to be pedantic about things, then you might as well go the full nine. Don't pussy out when it comes to free shiat to drink.

Gravitational acceleration is a vector sum. It can easily be canceled out by opposing forces. It also weakens proportional to r², so the influence of significantly distant objects can usually be rounded to zero when dealing with a local system. The local system in this case consists of ping pong balls, researchers, a 727, and the earth. The attractive force between the first 3 with regards to each other is negligible compared to the attractive force between each one and the earth (which is significant!). The 727, researchers, and ping pong balls are all accelerating downwards at exactly the same rate as the gravitational force acting upon them would cause them to accelerate in a vacuum. It is important to note constant "acceleration" in this case, as constant "velocity" would not produce the effect. The 727 is using engine power to overcome air resistance and continue accelerating towards system center of mass (SCOM) even after passing what otherwise be terminal velocity due to the atmospheric interference. This, combined with the enclosed atmosphere within the 727 remove air resistance from the equation, and allow the contents of the plane to accelerate towards SCOM as though they were in a vacuum. The researchers and ping pong balls stop exerting force on the floor of the 727 during the dive, because the 727 is accelerating towards SCOM at the same rate that gravitational attraction would accelerate the researchers and ping pong balls towards SCOM. This is not "Zero g", for the ping pong balls, researchers, and 727, because they are all accelerating towards SCOM at 100% the rate dictated by gravitational attraction.

Astronauts and space ships experience two significant forces when they are in stable orbit; the force of gravitational attraction, and the force of centripetal "repulsion" (for lack of a better term). These two force vectors oppose each other and result in a net zero acceleration with regards to the SCOM. This IS "Zero G" for the astronauts and space ship because they are accelerating towards SCOM at 0% the rate dictated by gravitational attraction.
