Our universe may have a doppelganger full of white holes and black stars
Better out than in
White holes
Scientists basically describe white holes as origin stories for black holes.
Imagine you’re staring at the edge of a black hole and you see a single particle enter it. It should take an infinite amount of time for that particle to travel through the center of the black hole due to its infinite mass.
So, if you time-traveled infinitely far into the future, you’d still see that particle being sucked into the black hole.
But what would happen if you then turned around and traveled infinitely backwards through time to get back to where you started? It’s paradoxical to imagine a vacuum sucking backwards, so we have to imagine the opposite of a black hole.
A white hole would be infinitesimally mass-less, at least in the respect that it would be a force that was as repulsive as a black hole is inescapable.
Yet, strangely, by description each would have an essentially impassable core mass.
Black stars
Scientists believe black holes are formed when stars collapse in on themselves. And that energy has to go somewhere.
Unfortunately, as we’ve established it would literally take forever to traverse the center of a black hole, it may be impossible to ever make the journey.
That might stop us from finding the truth, but the universe may not need our validation to exist in its true form.
Black holes could be collapsing to the edge of infinity where foreverness meets the eternal nothingness of a dark universe doppelganger.
Even though our black universe could be infinitely expanding, it may also be held in place by a white universe. Maybe white holes function as multiversal drain plugs that keep our universe’s physical and dark matter from leaking out through black holes.
Perhaps the white universe would appear as an infinitely bright cosmos dotted withblack stars– lightless quantum entities, eternally frozen in a state of collapse – and infinitesimal, ever-shrinking points called white holes.
