End is near... well, Trinidadian please love each other Are You Prepared ?
Earth is doomed to fry and then be gobbled up by the dying Sun.planet's demise is 7.6 billion years away that as the Sun runs out of fuel, it will expand into a dangerous "red giant".But Earth while battered and burnt to a crisp would escape ultimate destruction.Sadly, for our home, the number is up.The tenuous outer atmosphere of the Sun extends a long way beyond its visible surface, and it turns out the Earth would actually be orbiting within these very low-density outer layers."The drag caused by this low-density gas is enough to cause the Earth to drift inwards, and finally to be captured and vaporised by the Sun.Life on Earth will have become rather uncomfortable before then, however.A billion years from now, as the Sun slowly expands, the oceans will evaporate, filling the atmosphere with water vapour (a potent greenhouse gas) and triggering runaway global warming.One is to harness the gravitational pull of a ping asteroid to gently tug Earth out of the danger zone.
