How far is Heaven from Earth?
Perhaps an even more interesting question would be as follows: Why are we always so intent on details about this subject? Have faith, and someday you’ll find out. In the meantime, an interesting read for you would be Heaven is For Real, … about a little boy who died briefly after his appendix burst, and who came back to tell the tale in a most amazing way.
However, if I can take a metaphorical look at your original question, considering the quality of morality on the earth right now, I’m afraid Heaven is far, FAR from earth.
Many strides have been taken in space exploration through Hubble and the Spitzer infrared space telescopes. Each year brings an expansion to the distance to which scientists can see thanks to these space telescopes that orbit in space rather than view space from Earth. It is possible that your source of information got his or her data mixed together and told two or more advancements as one. I suspect the first is this. Hubble has in recent years detected “black envelopes” around (1) young protostars in early formation phases and (2) black holes inside black envelopes of swirling gas.
I suspect the second may be this. Astronomers and cosmologists now think that “dark flow” indicates a proof of the multiverse theory. Scientists now suggest another bubble multiverse is at the edge of our universe and is exerting a strange pull. This pull is causing the cosmic microwave background (CMB) to ripple and is causing the galaxies all over the universe to flow in the same direction toward one specific locale–this is opposed to a uniform unrippled expansion that spreads outward in all directions from one central locale.
When these two cosmological accounts (i.e., black envelopes and multiverse dark flow) combine casually, you may get something that sounds rather like “they reach a black envelop which no machine from earth can ever penetrate through to the other side, and they say on that other side that is where Heavenly Father God is.” For a person of religious faith, a reasonable counter-argument to the multiverse theory might be that the ‘”structure” at the edge of our universe is Heaven–beyond the bounds of space and time–and that it is exerting a pulling spiritual
