While we are on this subject I have a question for some of you smart guys out there.
With reference to the Einstein Field Equations:
1. Do solutions of these equations exist that predict Gravity Waves?
2. Are approximations required to achieve these solutions?
3. Are the solutions rock solid or could they be challenged?
The reason for questions:
We’ve never seen a gravity wave. Not one. So I’m interested in how accurately we believe we can predict the magnitude of the disturbance required to create a gravity wave detectable on earth.
Some scientists believe gravity is really a bend in space time, similar to a mass on a rubber mat attracting smaller masses that circle it.
I am not a Theoretical Physicist, but I play one on FR.
Here is how you observe a Gravity Wave:
Choose a star of sufficient magnitude and distance that you can get a continuous observation of its light spectrum 24 hours a day. Obviously this must be done via satellite like the Hubble Telescope.
Monitor and constantly record the magnitude of the red shift of the dark line of a common element in the star’s spectrum.
The magnitude of the red shift should remain constant.
If it changes during the monitoring and recording process, a gravity wave must have passed thru between the star and your observation point.
That’s weird, so a cat can be both dead and alive if gravity is sufficiently weak.
What about a human in intergalactic space?
We won’t have to worry about humans in intergalactic space for a loooooong time.............................
While I don’t doubt the above research, it is generally agreed that the effect of Large Numbers(TM) of weakly interacting systems and the resulting decoherance is the dominant mechanism by which quantum mechanical behavior transitions into macroscopic classical behavior.
IOW, where mass meets reality..................
And Schroedinger’s dog sat in the corner and laughed.
I used to think that time was altered by ass (as in my ex).
Really?
It seems to me that, once you’re off the planet, you are I intergalactic space.
“similar to a mass on a rubber mat attracting smaller masses that circle it”
The thing is, a depression on a rubber mat only causes that attraction because gravity already exists and is pulling the masses down. We can’t even imagine an example of how gravity works that doesn’t depend on a pre-existing notion of gravity!
First comes interplanetary space, then interstellar space, then intergalactic space..............
Or, interstellar space for that matter.
But there will be some great science fiction written about it, that's for sure.
The problem I see with the “rubber mat” theory of gravity is that it is always demonstrated along a flat plane, i.e., the gravitational pull affects along the plane of gravity. Except gravity is not on a plane but a 360x360 area.
What relationship does this have, for instance, on the Space Station, where the people onboard are weightless; NO gravity? Why don’t we see some of this weird phenomina out there?
Inquiring minds want to know.....where to acquire some of the stuff these guys are smoking, maybe?
Even though the people on the Space Station are in ‘space’, they are not outside of a gravitational filed. They are still in the gravity well of Earth and the Sun with the Moon causing periodic perturbations.
They do age slower, though, since they are in a ‘micro-gravity’ situation...............
One can witness the slowing down of time by watching the extremely obese on My 600lb life. Imagine how long their days are laying around because they can’t get out of bed...
Just saying...
