- Learn Time Dilation and Redshift for a Static Black Hole
***Gravity for a static black hole is Time dilation and gravitational redshift become more extreme the closer you get to the black hole, at 1 m from the event horizon (r=rs+1 m), you would only experience-

- Event Horizon vs Singularity: Are They the Same Thing in Black Hole . . .
The event horizon and the singularity are two distinct concepts in black hole physics The event horizon is the boundary beyond which nothing, including light, can escape the gravitational pull of a black hole It is defined as the point of no return for any object falling into a black hole
- Does Time Slow Down for Objects Falling into a Black Hole at the Event . . .
When I look at a minkowski diagram for a black hole I can see that time goes to infinity for the outside observer while the infalling object approaches the black hole That means that for an outside observer, it takes an infinite amount of time until the infalling object reaches the event horizon
- What Happens If You Stick Your Hand Inside a Black Holes Event Horizon . . .
Sticking a hand inside a black hole's event horizon would result in severe tidal forces that could tear the body apart, even before reaching the horizon The gravitational gradient near a black hole creates a phenomenon known as "spaghettification," where parts of the body experience different gravitational pulls For smaller black holes, tidal forces become significant well before crossing
- Theories about light and time near a black hole • Physics Forums
First, if a black hole absorbs enough matter, won't it's added mass change the distance of the event horizon? If so, then the theorized light sphere will only be present until that happens Second, is there any equation that tells us how much time dilation there is, relative to 1g on earth, at an event horizon?
- Gravity at Schwarzschild Radius of a Black Hole
One can approximate the proper acceleration required to be hold station at a certain distance d from the event horizon of a black hole by a = c^2 d, d being the distance from the event horizon as measured by a stationary observer This works only for d << r_s, where r_s is the Schwarzschild radius of the black hole The formula itself is independent of the mass or size of the black hole, but
- How Do Light Cones Behave Near a Black Holes Event Horizon?
There's a more mathematical reason for this too: the event horizon (s) of a black hole are something called null surfaces Have a look, for example, at Carroll's book or his online lecture notes for a pretty nice discussion of this Once the body goes past the event horizon its light cone does indeed "tip over "
