Gravity can be observed in the lab. We cannot duplicate it or manipulate it. We cannot simulate it. We do not understand how it works.
How would one define 'simulate' in this context ?
Can we not 'simulate' gravity in space using centrifugal motion, in as much as we simulate weightlessness on earth using a parabolic flight path?
You might say that we would be simulating the force of gravity and not gravity itself. If so; what defines gravity other than as a force ?
By comparison; I've seen flight 'simulators' offer a poorer simulation of flight than the two examples above, so what do you regard as a simulation in this context?
Can you not chemically simulate the Holy Spirit?

To a degree, yes. Both are just motions within a given gravity field. Heck, the gravity in low Earth orbit isn't much different than it is here - but astronauts and satellites cleverly fall at a speed at which they never actually hit the Earth.
Additionally, those same astronauts could fire up a rocket and accelerate towards the earth - and feel a 1G force pushing them _upwards_ within the confines of the rocket.
But all those cases are cases of inertia acting on a body in motion or at rest.
Every other force we know about in the universe is carried by bosons. The electromagnetic force is carried by photons; W and Z bosons carry weak nuclear force and gluons carry strong nuclear force. We can produce photons at will (fortunately, or we'd have trouble seeing at night.) We can observe and manipulate the other two kinds of bosons in particle accelerators.
But no one has ever seen a Higgs boson (which may give particles mass) or a graviton (which might serve as the force mediator for gravity.) We don't know how to detect them. We don't know how to make them. We don't understand how gravitons (if they exist) work. We can't block them, focus them, amplify them or attenuate them.
We can simulate the _effects_ of gravity through acceleration. But we haven't yet learned how to create, observe or manipulate the basic force.

Very true. Some people get the same effect with drugs and alcohol; others through nationalism or political party membership.

Yeah . . . Pretty intense watching that happen to a liberal.
Even funnier watching it happen to an extreme conservative!
But to the point - both can be proven the exact same amount.

The existence of gravity and the existance of an actual god? I think you've been taking too many of those 'simulants'.
Do you want to have an ideagasm?

Tell ya what, we'll take you up in a plane with no parachute, toss you out and see if gravity exists or not. On the way down, you can pray for god to save you and see if he exists or not.
Somehow I think it's far easier to prove gravity exists than god.

Nope.
He stated that gravity cannot be proven, but it is obvious. You can simulate it, and you can show it working, but you cannot show how it works or what makes it work.

"We" would be a necessity - how many do you think it will take?
By "we" - you mean whom?

Just because it is easier to demonstrate doesn't make it more or less provable.

The existence of God can be proven not at all. The existence of gravity can be proven to a great many decimal places. So unless you believe 0 = .9999, your statement doesn't work.
