Jesus can already do this and He says, "we shall be like Him". I suspect in the not to long future He will show us how. I used to read a lot of Joseph Campbell until I heard him say that Jesus left earth for heaven 2000 years ago and he still isn't there yet, traveling at the speed of light. I thought to myself, that's why the Bible says, "beware the wisdom of man". This brilliant man evidently did not know about other dimensions. Christ was in heaven in a microsecond. He will return the same way.
String theory may someday explain alleged UFO's as well..
Dimensional travellers, rather than "life on other planets"..
The "sleeping prophet", Edgar Cayce claimed in one of his "sessions" that humanity would indeed, meet intelligent life some day..
But it would be 10's of thousands of years from now, and they would be so far beyond us that we would consider them as god-like, and we would be completely beyond their notice..
That's pretty humiliating, isn't it?
To finally find life in the universe and find out you are no more than ants beneath their feet?
Great tag-line, by the way..
