Scientists Predict When World Will End
From a scietific perspective, the only hope for humanity...celestial bumperpool!
(Explains why recently there's been so much emphasis on finding another planet which can reasonably sustain human life..... but of course, if your only hope for humanity lies in this world, then you better search every nook and cranny! ... even though given your own lifetime, it won't do you any good!)
Note: it's not that Christians are opposed to science and the study of the physical realm, but to suggest one knows when the earth will cease to exist is like assuming to know all that tomorrow brings.
"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father." (Mt 24:36)
