Resumen de Our universe could survive its own end
The universe could bounce through its own demise and emerge unscathed. A new "big bounce" model shows how this might happen, with just the cosmic ingredients they know about now. They think the universe began with a singularity, when all matter and energy was compressed into a single point. The trouble is that the laws of physics break down at a singularity, so it's impossible to predict what happens there. According to the dominant theory, the universe ballooned in size in the first sliver of a second after the big bang in a period called inflation, but there are alternative ideas. One major contender is the "big bounce" model, in which their universe rose from the ashes of an earlier cosmos that ended in a "big crunch". But those models have also struggled to explain the singularity.
