I know that because of the great gravity pulling at your feet much not as much at the upper half of your body you become like spaghetti but I want to know why this happens and what else could possibly happen.
anj16 said:I believe it is if you either go through the event horizon or dive right into the center of the black hole you won't face the spaghetti effect.
The event horizon has absolutely zero to do with spaghettification. For small black holes you get spaghettified WAY outside the EH and for really really big ones you don't get it until WAY inside the EH.
anj16 said:Yes I do realize that. What I meant was that there is a way of going inside a black hole without getting spagettified. I read it somewhere just don't remember where.
PaulS1950 said:Because space time is pulled and distorted the person or object being "spaghettified" would have no sensation of it. .
PaulS1950 said:there is no gravitational effect on the falling object.
both of you are in "free fall" - there is no gravitational effect on the falling object
PaulS1950 said:There is no gravitational effect in free fall. - think about it...
PaulS1950 said:You are missing the point: You are riding the space/time curvature in free fall. There is a difference in the space/time curvature from one point on your body to another but you are still locked into a space time reference.
You are treating gravity as a force. It is not. It is simply the effect of bent time/space and objects following it.

phinds said:I HAVE thought about it. You don't seem to get the concept of tidal forces.
PaulS1950 said:If it exists as the effect of space/time curving then what an outside observer would see is the spaghettification process but the one in the local reference frame would be totally unaware that anything was happening to him. He would see the rest of the universe deforming.
PaulS1950 said:Jimmy,
The tides are also generated by the curvature of space/time. Just as a ball that is thrown into the air is following the curvature of space/time back to the Earth.
Gravity is not a force, it is an effect that we perceive from the curvature and velocity of the time/space around us.

PaulS1950 said:If you feel the need to hold on to the Newtonian concept of gravity as a force then fine. There are still people who believe that the world is flat. Maybe you could have a party with them. Mass bends space/time. Gravity as a force does not exist. There is no instance where space/time curvature will not explain the effects you are calling gravitational force but there are situations where gravitational theory does not properly explain the effects of bent time/space.
In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction
This is my last post on the subject.

Are there tidal effects on your body when you stand or turn or lie down? NO! why? Because the time/space you are living in seems perfectly normal to that frame of reference. The differences are only apparent to someone in a distant fixed point of reference.
Now, back to the black hole:
When sliding into the black hole you are traveling in a changing space/time frame and would be unaware of the changes that a distant fixed position observer would see.
Tidal forces were brought up but there is only one gravitational field, the one you are sliding into. Tidal effect only occur when two massive objects are close enough that their time/space deflections interact. As we slide into the black hole we are only effected by the one massive object which negates tidal forces. We remain in the same space time framework the whole way.
I leave you with that and the example of the spaceship and the compressed crew to consider both as the same concept.
Have fun with it and try to find any differences between the two examples.

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape it. This is due to the extreme curvature of space and time caused by a large amount of mass being compacted into a small space.
It is highly likely that you will not survive being pulled into a black hole. The intense gravitational forces would tear apart your body and the radiation and extreme temperatures near the event horizon would also be fatal.
Nothing can escape from inside the event horizon of a black hole, not even light. However, some particles and energy can escape from the outer edges of a black hole, known as the accretion disk.
Time inside a black hole is distorted due to the strong gravitational pull. As you approach the event horizon, time will appear to slow down, and at the singularity, it will theoretically come to a halt.
Currently, it is not possible for humans to travel through a black hole. The extreme conditions and unknown effects on the human body make it an impossible feat. However, some theories suggest that it may be possible to travel through a black hole in the future using advanced technology.
