parallel universe????? schrodinger's cat , grandfather's paradox???

Question

parallel universe as for the above is logical . but Novikov mentioned about puting a billiard ball into a warmhole and travel into the past knocking itself in the past and therefore not creating any paradox.is this possible if at all we put a ball into a warmhole and travell back in time and hit the ball ( coz hiting is not logical but practical)?????

Answer 1

yes parallel universe is logical.
I am taking out rights & wrong of ur info.

First the possibility of a warmhole may be to the least probabilty but can exist.

Now, if warmhole exist then the possibility of reaching ur past
increases.

But warmhole has tremendous energy & whtever reaches inside the warmhole shrinks in an unknown dimension,there is a sure tht u will reach the past u can see ur grandpa in his childhood but the ppl in the past will not be able to see u.
U exist but u can only see them & can do nothing.

for eg:- If u try to shoot ur grandpa in the past consider him at age 8.The bullet will penetrate & run out of his body without causing any harm to ur grandpa.


You will reach the past but can do nothing practically consider urself as if ur a soul.


It is possible tht u r sitting on ur chair & there may be ur great great grandson may be standing in front of u but u dont feel their existence as of current.

Answer 2

I just hate this experiment. It is so misleading. It isn't really a question of whether it is logical or not, logic doesn't apply to the quantum world as others have mentioned. But people, please think beyond what the inventor of this experiment is trying to lead you into. The cat is a macroscopic object. "Dead" or "alive" describe macroscopic and incredibly complex states of being in the biological processes of that cat. If the cat is really alive and dead at the same time, the number of quantum events that differentiate these 2 states is almost infinite after any length of time. Not possible unless it is true that every quantum event creates 2 separate universes. Some people believe this wacko nonsense. It is ridiculous just as it was when it was dreamed up decades ago. A lot of people misinterpret this experiment. Observation means that the object interacts with something else in the environment so as to force it to take a single state because the state of that other object in the future depends upon it. The cat is an observer! Anything that interacts with the quantum event in such a way that it must collapse the state so it may continue to change state is an observer. I certainly hope people aren't speculating that human cognition is the only thing that collapses quantum probability to reality. We aren't that self-centered, are we? The atom can be decayed and not decayed for a period of time until the particle produced by that decay interacts with something else that requires an answer.

Answer 3

Wormholes are more science fiction than fact. It comes out of some obscure solutions to equations .If they are possible, they would require more energy than the galaxy has to be produced.

Answer 4

what is all this about?
