Which consequence results when extreme spacetime curvature occurs near collapsing hypergiant stars?

A)Photon sphere forms around star
B)Neutron degeneracy halts collapse entirely
C)Accretion disk slows orbital velocity
D)Gravitational waves' spectra redshift abruptly

💡 Explanation

A photon sphere forms because extreme curvature bends light into unstable orbits via gravitational lensing; it creates a boundary where photons orbit before being captured or escaping. Therefore, a photon sphere is made, rather than degeneracy pressure halting collapse or affecting disk orbits.
