Default A 20 solar mass neutron star is discovered!

Sometimes you gotta just laugh at science journalists. This genius is
claiming that Cassiopeia A's supernova remnant is a neutron star of 20
Solar masses! You gotta wonder how it's able prevent itself from
collapsing into a black hole without nuclear fusion?

Other than that, the article is okay, describes a newly formed neutron
star that still has an atmosphere of carbon on it. The carbon was
created from left over fusion reactions in an atmosphere of hydrogen and
helium on the surface of the neutron star even after it had gone supernova.

CBC News - Technology & Science - Canadian physicist IDs young neutron star
"Craig Heinke and his colleague Wynn Ho at the University of
Southampton, U.K., say that the remnant of the supernova Cassiopeia A is
a very young neutron star, 20 times heavier than the sun, but only 20
kilometres wide."

It is horse****, that's why. There is no possible way it is 20 solar masses.

I think he just got confused with the mass of the progenitor star.

One of the most massive observed neutron stars is 1.74 solar-mass
pulsar PSR J1903+0327. 20 solar masses attributed to any neutron star
under any circumstances isn't even wrong.

Within the context of Discrete Scale Relativity, the upper limit
for Stellar Scale black holes or neutron stars [which are the
former in low to very highly excited states] is roughly 30 solar
masses.

Nature and empirical evidence trumps theoretical assumptions.
Every time.

Now we wait for the furious backpedal once the misreporting error is
revealed.

Not a very scientific response, and certainly not a scientific
argument.

NOTE: A crucial characteristic of definitive predictions is that they
cannot be "adjusted".

If DSR is right, then 20 solar mass neutron stars must exist. If the
latter do not exist, then DSR is wrong.

ALSO NOTE: The highest mass black hole so far observed has a mass of
about 30 solar masses.

This is called doing real science, as opposed to untestable post-
modern landscaping.

Are we clear on that point, Mr. Gisse?

I am intolerant of stupidity and those who are proud of it.
Ignorance is not a form of knowing things.
