Scientists ponder the problem with gravity

Imagine the weight of a nagging suspicion that what held your world together, a constant and consistent presence you had come to understand and rely on, wasn't what it seemed. That's how scientists feel when they ponder gravity these days.

[Semper Paratus]

Gravity challenge is something Lizzie Edwards could relate to.

[roaddog727]

Yep,
Sheould could use some anti-gravity assistance.....

[My2Cents]

LOL...A few more burgers and she'll be in danger of gravitational collapse.

From the article... Which leaves open staggering possibilities that would force wholesale reprinting of all physics books: --Invisible dark matter is tugging at the probes --Other dimensions create small forces we don't understand --Gravity works differently than we think Life gets more like science fiction every day.

Weighty topic.

[kingattax]

ok, astrophysics and math students......what would Lizzie the

Hut weigh on the moon ?

Here's the original:

Suppose gravity is a "push" rather than a "pull",
and mass blocks it rather than generates it.

Now, suppose it's neither.

[ErnBatavia]

John Kerry would probably look perfectly normal, for a change, were he to experience weightlessness...

Remember those coliolis acceleration problems in dynamices?

A bug starts in the center of the spinning record and starts walking to the edge....

[Larry Lucido]

Nah, it has no gravitas.

[Larry Lucido]

Suppose gravity is a "push" rather than a "pull",

Now, suppose it's neither.

That gets me every time, too. I especially hate when one of them is locked.

..better yet, Michael Moore. ...than Lizzie Edwards...Jerry Nadler. :/

FORD:
Yeah, well, Forget that. I mean do you know how the universe began for a kick off?

ARTHUR:
Well probably not

FORD:
Alright imagine this: you get a large round bath made of ebony.

ARTHUR:
Where from? Harrod’s was destroyed by the Vogons.

FORD:
Well it doesn’t matter -

ARTHUR:
So you keep saying!

FORD:
No, No listen. Just imagine that you’ve got this ebony bath, right? And it’s conical.

ARTHUR:
Conical? What kind of bath is -

FORD:
No, no, shh, shhh, it’s, it’s, it’s conical okay? So what you do, you fill it with fine white sand right? Or sugar, or anything like that. And when it’s full, you pull the plug out and it all just twirls down out of the plug hole… but the thing is…

ARTHUR:
Why?

FORD:
No, the clever thing is that you film it happening. You get a movie camera from somewhere and actually film it. But then you thread the film in the projector backwards.

ARTHUR:
Backwards?

FORD:
Yeah, neat you see. So what happens is you sit and you watch it and then everything appears to swirl upwards, out of the plug hole and fill the bath… amazing.

ARTHUR:
And that’s how the universe began?

FORD:
No. But it’s a marvellous way to relax.

[Lorianne]

I ponder the problem with gravity more and more every day.

[markytom]

I think Karl Rove must have something to do with this :)

The "other dimensions" stuff is a bunch of hooey. After 1905/1915, it wasn't fashionable to say "material properties" when referring to a region of space so they had to come up with something new.

Ask The Imam: Does gravity exist or is it made up?

We do not understand your question as everything existing is made up.
