We can see light from stars that are over 6,000 light years away, even though the universe was created 6,000 years ago because time passes much quicker in empty space where there is less gravity than on earth. This is because the rate of time is inversely proportional to gravity. The more gravity, the lower the rate. the less gravity the higher the rate, meaning the faster that time changes...

science professor yelling though loud speaker: YOU ARE UNDER ARREST FOR MANIPULATING INTELLIGENCE! NOW STEP AWAY FROM THE PSEUDO SCIENCE BOOK! ANY SUDDEN SPEECHES ABOUT YOUR PSEUDO SCIENCE AND WE WILL, AND I WILL REPEAT, WILL THROW HARD ENCYOPEDIAS AT YOUR HEAD!!!
i end my drama here...lol
Then, as shells of expelled material move further from their parent supernova, and hence away from its gravity, they would appear to us to be moving faster.
Fortunately, SN1987A allows us to confirm that fact through direct observation...

Nope. You fail.
(Explanation of above.)
As the ring is tilted with respect to our viewpoint, one side of it is further away from us than the other, and crucially on the other side of the supernova remnant.
The supernova shockwave is spherical and will impact the earlier ejecta at the same moment (from the POV of the supernova), causing it to glow. The light from that glow will take less time to reach us from the nearest side than the farthest, so we should (and do) see one side of the ring brighten before the other.
Now the light from the farside of the ring is intially moving towards the supernova, while the light from the nearside is moving away, hence if gravity worked the way JD777 suggested, we should not see just a 'trigonomic' progression (where the delay is proportional to the distance), but also an additional delay where the closer to supernova remnant the glow passes the longer than (trigonomically) expected it takes.
But there were no 'unexpected' delays, and in fact the trigonomic method was good enough to let us accurately determine the distance to SN1987A

But since I image JD777 probably believes supernovae are caused by angels falling from grace, I doubt he'll accept this for a second.

Since I ascribe to the theory of intellectual osmosis, I am going to keep as far away from that video as possible. I don't want to end up as retarded as those fundies.
let phi the gravitational field be P , C be the speed of light in a vacuum. ds represent the non Minkowski space time metric ( just picture this as the Lorentz transform applied to 4 dimensional space-time, x,y,z,t = s)
the proper time (t') measured at a clock fixed in space at (x,y,z) in time delta(T) defined as dT measured at infinity (i.e where P = 0)
dt' = 1/c[(-ds^2)^(.5)]
therefore dt' = [1 + P/c^2].dT
I hope that clears that up for you now.

Yes, I've said the same thing many times myself.
Teaching science the JesusDisciple777 way; lesson one.
Light... Star... Light year... Gravity... Rate of... Time... Galaxy... Proportion... Universe...
Have their eyes glazed over yet? No, not quite. Maybe a few more will do it:
Dimension... Supernova... Gravity... Star... Cosmos... Light spees... Star... Gravity... Star... Universe...
That's done it, they're all sufficiently stupified... AHEM! Therefore the young earth hypothesis is proven!

Maybe JesusDisciple777 believes we humans live in a gravitational field on the order of 1011 g .
May Stephen Hawking crush your toes with his wheelchair for this epic failure at astrophysics, JesusDisciple777.
My calculus teacher would just rip strips off of you.
We see some galaxies that are millions of light-years away.
MILLIONS
I don't pretend to know anything about this, but something tells me that light going from 300,000 m/s up to over a billion in order to satisfy your BS might just be impossible.
Because, y'know, when light's wavelength changes, it stops being light.
I got a C in high school physics. And high school physics deals mostly with classical Newtonian mechanics. I don't understand much of anything in the realm of physics. I can't do math to save my life. As I barely managed to pass a basic high school physics class, I think that it's safe to say that my understanding of things like the speed of light, gravity, and the theory of relativity (both general and special) is next to nonexistent.
But even I know that this is utterly, mind-bogglingly, brain-meltingly, headdeskingly, cosmically wrong. Even I know that physics does not work that way! If I'm in pain over just how wrong this is, anyone with any actual understanding of the subject must be in sheer agony.
Well, time IS slowed by gravity. Actually, it is stretched out, along with space.
You know what? Makes a lot more sense when Terry Pratchett explains it.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
