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.
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.I believe it is if you either go through the event horizon or dive right into the center of the black hole you wont face the spaghetti effect.
Yes I do realise 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.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.
What does "inside a black hole" mean to you? The only meaningful thing I can think of is "inside the event horizon" and I have already stated that you don't have to "do" anything to get inside the EH of a really large BH without getting sphagettified, it just happens that way and there is absolutely nothing you can do to avoid sphagetification outside the EH of a small BH.Yes I do realise 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.
I cannot imagine how you can justify that statement. The sphagettification is real. How could you not experience it (for the little time you remain alive).Because space time is pulled and distorted the person or object being "spaghettified" would have no sensation of it. .
You are missing the point. Sphagetification is not caused by the gravity, it is caused by the DIFFERENCE in gravity between your head and your feet. Do you understand the concept of tidal forces?there is no gravitational effect on the falling object.
There is a gravitational effect- tidal force.both of you are in "free fall" - there is no gravitational effect on the falling object
This is incorrect. Tidal forces DO happen in many other cases, and the results range from benign to catastrophic. For example, the Earth's tides are caused by tidal forces arising from gravitation. Tidal forces can also rip stars apart in binary systems if a star gets too close to a neutron star or other small massive object. You are never "locked in" to a spacetime reference, whatever that is supposed to mean.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.
The way spacetime curvature manifests itself is easily able to be described as a force in almost all cases. And I don't really know what you mean when you say "there is no gravitational effect in free fall". Free fall is a direct result of gravity, so it is itself a gravitational effect. Did you mean something else?You are treating gravity as a force. It is not. It is simply the effect of bent time/space and objects following it.
There is no gravitational effect in free fall. - think about it....
Phinds is correct. Einstein's equivalence principle only holds in local coordinates. That is, over sufficiently small intervals of time and space. Otherwise, gravity has certain effects that acceleration does not (such as the tidal effect).I HAVE thought about it. You don't seem to get the concept of tidal forces.
I suggest you read this article on the effect: http://en.wikipedia.org/wiki/SpaghettificationIf 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.
Yes, tides are the result of gravity. They are also an example of weak tidal forces. Strong tidal forces can, and will, rip objects apart. See the article I linked in post #18 about it.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.
The issue whether gravity IS a force or not is only a minor one. From wikipedia on force: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.
I believe that gravity, in general, meets this definition. But it also requires a vastly more complex description to completely describe it's effects. Hence the reason General Relativity works.In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction
Goodbye then. Feel free to return when you are ready to put your arrogance aside and listen and learn.This is my last post on the subject.
Yes, and this contradicts your statement that a freely falling object experiences no "gravitational effects".PaulS1950 said:The tides are also generated by the curvature of space/time.
