I have currently finished a five-year (unfunded) project developing what was to become a very controversial hypothesis. On the face of it, even I admit that it beggars belief... BUT once broken down and considered alongside very powerful visual evidence, the hypothesis holds its own. I have entitled my hypothesis The Impact And Exit Event and as the name suggests I believe I have uncovered strong evidence which indicates that a huge piece of space-bound debris not only impacted with Earth - it hurtled through its mantle and burst out of the other side (i.e. 'The Impact And Exit Event'). Following on from this I then found myself making further discoveries on a similar scale elsewhere on Earth and across the Solar System... This is extremely far-reaching stuff, so you will need to be patient, lock away preconceived ideas and postpone your final judgment until learning further, hopefully via this thread and elsewhere on the Internet. Anyone interested in further discussion?
