Black Holes: Anybody out there?
2015 (English)Report (Refereed)
Using analytical results from both general relativity and quantummechanics we show that physical black holes probably do not exist.This would actually be a boon to theoretical physics, for example as:i) General relativity would then be globally valid in the (classical)physical universe, due to its non-singular nature.ii) The black hole information paradox would vanish.iii) No event horizon would mean no Hawking radiation, resolving thecausal paradox that for an outside observer it takes an innite timefor the black hole to form whereas it evaporates in nite time.Astrophysical applications that seem to require black holes (quasars/AGNs,stellar motions near the center of our galaxy, etc) can still be fullledby compact but non-singular masses, M.
