From Big Bang to Big Picture: A Comprehensive New View of All Objects in the Universe


Published on: October 31, 2023,

There are many theories of universe’s history. Astronomers have presented the most detailed view of universe’s history suggesting it may have originated from ” instanton” rather than a singularity. This revelation visualized through two innovative plots which delves into the mysteries of the universe’s boundary. The most comprehensive view of history of the universe ever created has been produced by researchers at The Australian National University (ANU).


Lead author Honorary Professor Charley Lineweaver from ANU says, “| When the universe began 13.8 billion years ago in a hot big bang there were no objects like protons, atoms, planets, people or galaxies. But the Universe today is full of such objects.  The answer where they came today is that as the universe cooled all of these objects condensed out of a hot background.” To show this process  in the simplest possible ways the researchers made two plots. The first shows the temperature and density of the universe as it expanded and cooled. The second plots the mass and size of all of the objects in the universe. With the plots combined the result is the most comprehensive chart ever created of all the objects in the universe.


Part of this plot are forbidden where objects cannot be denser than black holes or are so small that quantum mechanics blurs the very nature of what it really means to be a singular object. But what potentially lies beyond them remain a major mystery. The plot suggests the universe may have started from instanton which has a specific size and mass rather than a singularity which is a hypothetical point of infinite density and temperature.  The plot suggests if there were nothing a complete vacuum beyond the observable universe our universe would be large low density black hole which sounds scary but that’s not the case.
