- TL;DR Summary
- This forum has been asked many times about whether an infalling mass can cross the Schwarzschild Radius. The answer is YES, it will & I agree. However, what I don’t know is the amount of “gravity-free” time it will take to reach the Event Horizon; is it hours or trillions of years?

**Gratings**

The following is an example of a question that I have been battling to get my mind around for some time:

How long, in gravity-free time (Tᴓ-time), would it take for a stationary, one kilogram, point-mass to fall directly towards a non-spinning, accretion-disk-free, singularity in a Black Hole, weighing ten solar masses, from ten times the Schwarzschild Radius (Rs) to the Rs?

I would really like to know the exact Tᴓ-time taken together with a brief outline of the calculation.

I don’t have the mathematical skills to prove/disprove it but I suspect that due to extreme distortions of time & space, there may be a point just outside Rs where the point mass will be moving at near the speed of light and only move one micrometer in one billion years in Tᴓ-time?

To those that may reply, I wish to thank you in advance for your kindness, time & effort to enlighten me. And especial thanks to those who may come up with an actual time.
