The End of Everything explores five possible scenarios for the Universe's ultimate demise: the ‘big crunch’, ‘heat death’, the ‘big rip’, ‘vacuum decay’ and the ‘ekpyrotic scenario’.Mack seamlessly weaves her way through the essential physics you’ll need to understand each Universe-ending possibility. Don’t worry if you haven’t heard of, say, the ekpyrotic scenario because the author gives us a readily graspable explanation of this and many other concepts.
