Did the Big Bang arise from nothing? Or from a previous bygone universe? The first matter But before we get to that, let’s take a look at how “material” – physical matter – first came about. If we are aiming to explain the origins of stable matter made of atoms or molecules, there was certainly none of that around at the Big Bang – nor for hundreds of thousands of years afterward....

Did the Moon ever have a strong magnetic field? Here’s what modern geophysics tells us The Moon lacked a magnetic field for nearly all its history – New research resolves mystery sparked by rocks brought back on Apollo Why a magnetic Moon? Certain rocks have the extraordinary ability to preserve records of past magnetic fields when they contain minerals with iron atoms thatalign with a magnetic fieldas the rock cools and solidifies....

Did the world actually end in 2012? Don’t you just hate long goodbyes? Reality? No thanks The first challenge we need to overcome is reality. We could take the philosophical view and point out that all of this could actually be a space turtle’s dream. Or, perhaps more believably, a computer simulation. Oxford philosopher Nick Bostrom’s simulation argument hypothesizes that we’re either in a simulation now, or people in the future aren’t capable of creating one....
