if gravity is too strong then it will break a object apart as gravity is strong enough to break the chemical composition of object why we consider "Spaghettification" relevant in this case ?

    $\begingroup$ Spaghettification is not possible at the event horizon of a SMBH because the tidal forces are not strong enough. If the black hole is, say, 1 solar mass, then objects would be spaghettified before entry into the event horizon. $\endgroup$ – fasterthanlight Feb 25 at 17:30
  • $\begingroup$ I am not an astronomer, but my understanding is that spaghettification is the phrase describing strong tidal forces rather than strong gravity. In this context the tidal force is the difference in gravity between two points relatively close to each other (such as the head and the toes of the astronaut falling into a black hole). Basically the derivative of gravity (as a function of the distance). There is no need for the tidal forces to be strong at the event horizon when the event horizon is far out (for a suitable definition of far out). $\endgroup$ – Jyrki Lahtonen Feb 28 at 5:56
