I know the above question title is one of the worst you will se here, and I am glad you still choose to read this post. I am a grade 8 student so with my limited knowledge I am asking this rather dumb question;
From my knowledge in the vast depth of Quantum Physics I will choose Schrödinger's cat Experiment,
it states that the cat may be alive and dead at the same time (something called as quantum superposition) until we observe it, now what does observe mean here? I mean here in Schrödinger's cat Experiment we might say that observing means to open the box and see the state (condition) of the poor cat.
But, if we look it from a more natural perspective we can say that if the cat is inside the container then it might to certainly produce some noise then without even observing it (cat or opening the container) we can say that it has to be alive at that instant.
Thank You So Much for making me understand that either this is conveyed by someone else or I am a dumb and should rather focus on something else joking, Thank You for letting me know about the following by spending your precious time helping me out.
Thank You on behalf of a 8th grader!
