Invisible dark matter of an unknown but nonbaryonic
nature must be the dominant ingredient of
the entire universe.
The Big Bang requires sprinkling galaxies, clusters, superclusters, andthe universe with ever- increasing amounts of this invisible, not-yetdetected
“dark matter” to keep the theory viable. Overall, over 90% of
the universe must be made of something we have never detected. By
contrast, Milgrom’s model (the alternative to “dark matter”) provides
a one-parameter explanation that works at all scales and requires no
“dark matter” to exist at any scale. (I exclude the additional 50%-
100% of invisible ordinary matter inferred to exist by, e.g., MACHO
studies.) Some physicists don’t like modifying the law of gravity in
this way, but a finite range for natural forces is a logical necessity (not
just theory) spoken of since the 17th century. [29,30]
Milgrom’s model requires nothing more than that. Milgrom’s is an
operational model rather than one based on fundamentals. But it is
consistent with more complete models invoking a finite range for
gravity. So Milgrom’s model provides a basis to eliminate the need
for “dark matter” in the universe at any scale. This represents one
more Big Bang “fudge factor” no longer needed.
