The growing evidence for blackholes isn’t
one to argue against, but some still feel that the odd nature of these
celestial suckers are reason to doubt their existence and to be honest I pretty
much see the reason for this doubt . yes
even though highly dense objects exists this doesn’t make them blackholes,
another object with high density would be
gravstar and still it wouldn’t qualify as a blackhole.
Earlier this year gravitational waves
were detected, the last prediction gotten from general relativity , detected by
LIGO and this was definitive proof that gravitational waves exists and it was
produced by two merging black holes and with this merger we could calculate the
masses of the initial and final black holes. We know that black holes should
depend on quantum gravity and if they did would gravstars also have the same
property making it hard for us to differentiate between the two . it turns out
yes ! we would be able to differentiate between both celestial machines the
detection however wouldn’t be in the same way we detected gravitational waves.
According to the models, gravstars are so
dense they have collapsed into the point of almost becoming a black hole. The
merging of two gravstars would also
produce gravitational waves but the difference would be in their vibration,
their chirp. Well ofcourse that chirp would be seen as background noise buried
in the data.still an argument would still be that either we detected a black hole
or a gravstar we can’t be sure.
However this could mean that the existence
of a black hole is one for debate ? nope
, not that fast . Infact while gravstars models argue against black holes there
is no definitive ,compelling argument or evidence for the existence of gravstars.it is
good to be skeptical but that is the adventure of science !
