Subtlety

U.S. astronomers spotted a huge explosion in space. Scientists calculate the blast to be stronger than 9,000 supernovae.

20,000 light years from earth
A million-trillion times as bright as earth's sun

Gamma rays -- which are released by an eruption of this sort -- are able to penetrate matter. Said astrophysicist Frank Reddy of NASA, "These things don't stop for anything -- they just bore through and that's why we can see them from enormous distances."

After His Resurrection Christ walked through a solid door to stand beside His Apostles in the upper room. The quality of a Resurrected body that allows it to pass through solid objects with ease is called Subtlety.

I'm not suggesting that a glorified body in Heaven -- one in which the body is perfectly in tune with and subject to the soul -- is like a gamma ray. I'm just pointing out (perhaps for the sake of those who like those who like empirical support for a proposition?) that with the gamma rays escaping a supernova we have an example in the physical universe of one thing being able to pass through another with alacrity.

For the record, in addition to subtlety, there are three other attributes of Resurrected bodies in Heaven:
* Impassibility: incapable of experiencing physical pain or corruption
* Agility: free and swift movement -- with the quickness of thought, in fact
* Clarity: to shine with a brilliant radiance and beauty
