The Weird Quantum World (11 of 15)

Episode 11 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn how Einstein's explanation of the photoelectric effect was one of the first steps towards a quantum mechanical view of the universe. Brian and other scientists explain some of the strange implications of living in a quantum world.

it seems that to understand the big bang it is necessary to unite quantum effects and relativity somehow.

Electroweak force and strong force make perfect sense in the quantum world. gravity, time and space make perfect sense in the relativistic world.

But they seem to not fit together well. gravity seems to be just different from the other forces. Maybe it is. Maybe there are two seperate forces. I hope they get united. would be cool

I wonder what future physics will say about modern physics in a thousand years, assuming continuing scientific progress. (Since I'm... skeptic about the viability of human civilization over the long term if there aren't major changes. (Especially in regards to overpopulation.)

But lets be optimistic... I wonder... are we close to the answer, or are we kind of like Newton, creating systems that are useful, but quite... rough compared to what will be known in the future?

@omnissient What I think is that gravity IS the same. Force travels through strings, which are most of the time attached to membranes. Different frequencies of the force movement makes different forces and different particles.. Although, gravity is not attached to a membrane, it just floats around in it, although force is an 11 dimensional object, and sence it is not attached to this 4 dimensional world, it floats off into other dimensions which makes it weaker. The frequency makes it different.

@Avatarass naaah, he still was a genius, he just got stuck in his ideas and did not wanna be open to other ideas, had he lived in our time i wonder what he could do for sceince

[Avatarass]

@hovsec Einstein was against the quantum theory. Some genius he was. He wasn't a genius, just a guy with large imagination.

albert eisntein, genius, i wish they woul explain the photoelectric effect a little better

Nothing comes from nothing. Somthing does not come from nothing, it is illogical to think that way something comes from nothing.

@Shavarnarak >"quite... rough"

We know so little. Eg about emergence or what's beyond the first 10^-43 seconds, heck we don't even know if the volume of the universe is infinite.

But I think the bigger question is: how far can we go with our evolved brains? I guess we will hit the limitations of the brain WAY before we come close to a complete understanding.

Maybe we can build smart machines to pick it up from there - which could make science documentaries for us, but without the heavy math. ;-)

@womo1975 >"I would love to see all the scientists, atheists, and organized religous members faces when this happens."

That's a pretty mischievous thing to say. I hope there will be some decent ppl up there who feel bad about fellow humans (like me) being hurt for not accepting unsupported claims, and start a petition or something.

Btw: How could anyone be happy in heaven knowing that others are in agony, just because they tried to be honest. How would that feel after the first trillion years?

[womo1975]

All points lead to God. I cannot wait for judgement day. I would love to see all the scientists, atheists, and organized religous members faces when this happens.

Uncertainty is only a definition, the thing being uncertain does not have understand it like being uncertain, or even be uncertain. We only define it as such out of the observation of Newton's Laws, and that's exactly why we conceived it as being uncertain as opposed to predictable.
