Similarly, spin and strangeness can also enter and escape from theBlack Holes. By the same argument, if a Black Hole is made uppredominantly of antimatter then dominantly matter can enter it.
Now the entered antimatter can interact with parent matter of aBlack Hole annihilating it and producing radiation. The same is trueof Black Holes predominantly composed of antimatter. If the processof entering and annihilation continues then ultimately a significantpart of matter and antimatter would convert into radiation shrinkingthe size of the Black Holes and if a criticality in mass-radiusrelation is reached then that may result in quasi-singularitycomposed of various elementary matter and antimatter and radiation.
Such a singularity would explode and after ?Big Bang? maycreate new structures. If the Black Holes consume the whole Universe,then that particular singularity can lead to creation of a newUniverse.
This is possible as according to astronomers? observations, theUniverse is expanding and it will continue to expand till a criticaldensity of the Universe is reached and below that density theUniverse could start to shrink, ultimately crunching into a pointmass; just like what it was at the time of origin of this Universe.
According to most modern updated theories a 4 dimensionalhypersphere Black Hole or its later avatar Big Bang, embedded inhigher 5 or 6 dimensions, exploded and created this Universe.According to Professor Stephen Hawkins all matter would end up insingularity and would ultimately explode.
Now there are three objections to the above argument. First ofall, many of the Black Holes may be result of collapse of massiveneutron galaxy or combination of galaxies. In that case enteredmatter and antimatter would not annihilate much and thus may notshrink the size of that Black Hole.
Moreover, the relativecomposition of the Universe is asymmetric: that there is more matterthan antimatter even if dark matter is taking into account, while thevacuum polarization produces equal number of matter-antimatter pairsfor a while.
Also, the fraction of neutral mater (and not their constituents)could be higher than that of the charged matter. Therefore, there isa limit as to how ?dark? the Universe may become and how manyBlack Holes can shrink to become singularities and ultimately an?ultimate? Big Bang singularity.
Second thing is other than Black Holes there are objects conceivedby physicists, known as White Holes; which don?t accept any matterand radiation, except with certain exceptions. Therefore, again theremay be balance in the Universe even though White Holes are not provenobjects as per scientific observations.
The third objection is that inside a Black Hole normal fieldtheories may not apply and even matter and antimatter can exist assuch without getting converted into radiation. Moreover, such stronggravity may convert radiation back into matter-antimatter pairs.
Thecurvature of space-time is so strikingly high inside Black Holes thatbeyond a size explaining them may require inventing new physics. Atthe best the physics inside a Black Hole and inside a White Hole isnot properly understood.
The best thing for the whole humanity is to try to live longestand to believe in the positivity of the Universe: that it may allowthe most talented human civilization to live forever; may be bycreating a Universe of its choice. But for that we will have to thinkintelligently and minimally understand the origin of this Universeand if there are more, then theirs? too.
If somebody excellent in physics reads this article and finds myarguments incorrect then I?m sorry for that. I don?t claim that Iunderstand physics except as a generalist: in fact not at all.
