Researchers Find Source of Strange 'Negative' Gravity

Sell my stock and head to Las Vegas. Is that what you're saying ?

Leave now, or can I at least let Ms. Onona know ?

The dark matter was sucked into a black hole by negative gravity.

Where’s my Nobel Prize?

[Yossarian]

That looks like PacMan’s grampa.

[CivilWarBrewing]

So that's how he lifted massive boulders at Coral Castle, using sound waves?? What's in the mystery box at the top of the hoist???

[blueunicorn6]

So, ladies and gentlemen, the next time you have to stand on a scale, just start singing really loud.

That’s the trick.

[Aevery_Freeman]

Now we know why Flying Saucers hum like that - it’s anti-grav!

[samtheman]

I wish there was a science gambling site. I would bet big on this theory dying soon.

A phonon — a particle-like unit of vibration that can describe sound at very small scales — has a very slight negative mass, and that means sound waves travel upward ever so slightly, said Rafael Krichevsky, a graduate student in physics at Columbia University.

First off--how can *anything* have *negative* mass?

Second, perhaps the slight upward travel of sounds waves doesn't actually exist--it's just that sound does not follow the curvature of the earth, so it just *seems* like it's rising.

Third--this is a graduate student we're talking about here, and his "findings" are given this much consideration?

[HiTech RedNeck]

From the description, it sounds (no pun intended) like something analogous to the Bernoulli effect.

[Crucial]

If this paper is true, you may be onto something.

[richardtavor]

I disagree with the theory. The older I get, gravity gets heavier and heavier.

[Eddie01]

The dark matter was sucked into a black hole by negative gravity.

Where’s my Nobel Prize?

Not so fast blue.

Dark matter is matter that travels faster than the speed of light. -Eddie01 '18

[HiTech RedNeck]

The “negative mass” is an apparent, not a real, property due to a phenomenon similar to how the Bernoulli effect contributes to the lifting force on an aircraft wing.

[Delta 21]

THIS powers my flying saucer. Turn it up. It works more better.

[ShadowAce]

Perhaps—but that’s not what the article said.

[ETL]

Lol! No matter how that strange little guy did it, for his “sweet sixteen”, it’s amazing. Like a small-scale version of the pyramids mystery. Well, something like it anyway.

[antidemoncrat]

Yeah. My butt suffers from positive gravity. When I get close to my recliner its gravity pulls it right into a collision course.

[HiTech RedNeck]

It said it in a different way, by speaking of the effects of the sound waves themselves on the density of the substance through which they travel. By reducing the density of the substance above in a gravity field, the sound wave induces its own (slight) upward travel. This must be something very slight, or we’d already know about it in standard acoustics.
