Revelation is all written in fantastic picture language that could mean lots of things. It's designed to freak you out a bit. An example:
'Then the third angel sounded: And a great star fell from heaven, burning like a torch, and it fell on a third of the rivers and on the springs of water.
The name of the star is Wormwood. A third of the waters became wormwood, and many men died from the water, because it was made bitter.'
I found out yesterday that 'Wormwood' (a relative of mugwort and tarragon) translated into Ukrainian is 'Chernobyl'. Now read that passage again.
