I <3 quantum physics

These things are so strange, but so awesome. If this interests you you should look into dark matter and dark energy researches.

deep... i can't even begin to tell you how much sleep i have lost thinking about things like this since i was about 18...

physics is cool

You've all been smoking weed haven't you, don't lie, I can tell.

Physics is da bomb yo.

it's a nice story but someone in the comments section ruins it with common sense

No he doesn't, he's being pedantic and suggesting that it's saying a being has to observe to collapse the wave function, where as it is actually the environment. The experiment is simply an illustration of the fact that changes in environment collapse wave functions, humans are part of that environment after all, and the fact that us seeing it (though the sensor) is what collapses the function is a necessity of the experiment because we have to be there. If we're not there then it doesn't happen by the simple fact that we are somewhere else doing something else.
Everything in reality is in super position, but there are positions of greater similarity, it's the cumulative effect of these positions that produces a seemingly stable reality.

the wording in the video suggests the state of being observed causes it, not the interaction caused by the observation methods

stanton's already acknowledged that pk... god get off his back, prk.

you wrote it

trouble is the 'sceince' i was taught at school wasn't made to look as exciting as that. to get kids into it you need to have lots of flashes and bangs and booms

nice premise for a train of thought but the animation in that is terrible
