The Multiverse Hypothesis Explained by Brian Greene

The multiverse hypothesis and the concept of multiple universes depends on the conception of reality as a four-dimensional space-time continuum in which "everything that could possibly happen does happen in some universe. The prominent theoretical physicist, mathematician, and string theorist Brian Greene explains the multiverse hypothesis in detail.

The multiverse hypothesis has been criticized for a number of reasons:

Some physicists claim that the multiverse hypothesis is not falsifiable, and therefore not scientific. In response, defenders claim that the multiverse is testable and some suggest it may be more scientific than certain other untestable theories.

Some proponents of the theory say there are an infinite number of conceivable universes. According to quantum mechanics, universes without any classical space and time—idealised as sets of quantum wavefunctions—cannot be directly observed because they do not interact with anything in our universe and would have no effect on future events in our universe.

Brian Greene explains our universe would be affected by the ripples from bubbles of another universe that it bumps into as it passes by. However multiverse models are problematic because they can not explain why the Big Bang happened at all or why the laws of physics are as they are today, which seem to follow from mathematical constants.

The American theoretical physicist and string theorist Brian Greene discussed nine types of multiverses.

A multiverse of a somewhat different kind has been envisaged within string theory and its higher-dimensional extension, M-theory. But we will discuss these theories extensively in another video.

I actually had the privilege of meeting Brian Greene a couple years ago. Very humble, smart guy.

Brian Green is one of my favorite people on this particular Earth.

[FredHerrman]

Brian Greene is SO good at explaining difficult concepts.

The real truth is beyond what we’re able to comprehend.

I had a spiritual experience 32 year's ago while in meditation, part of the experience was involved leaving our universe and seeing the multiverse from which I discovered much later is called the axis mundi

I want to live in the universe that science videos have hundred million views more than bullshit music videos.

But according to the Simulation Hypothesis (and the Double Slit Experiment) things don't exist until the observer collapses the wave function.

In other words, like a computer game, scenes are not rendered until the player steers his view to the scene.

That means, other universes do not exist until a conscious observer looks at it.

Therefore, multiverses only exist as potentials at any one time.

Absence of evidence is not evidence of absence.

Guys this is going to be deep but read this:

If every decision we make creates a new universe in the multiverse, then what counts as a decision? Can animals have decision, can plants or even not-alive things? If only our (human) decisions made universes then we must live in a simulation, because we are the one chosen species, but at what point did we become humans and not monkeys? Okay lets say this last one was not true, and every ALIVE thing can create alternate universes with their decisions, then what's the point of them? If we maybe die, we could "load our last savefile of the simulation" and start again without dying? But then there must be some kind of higher form of existence after death, where we can still choose between the alternate universes (but animals couldn't?). But lets say if there were no alive beings in this universe then there were no "Random" events, like a decision (which could also not be random but i wont go into Determinism now) then there must be only ONE and not more ways that the things in the universe happen, no random events, just an exact linear timeline, where every time we would start over the same thing would happen. That way there would be no need for alternate universes and they would not be created (if they are created the previously explained way).

I know nobody will read this😅. But if you do then have an amazing day and what do you guys think about this topic? :D

If The Multiverse theory is correct than there has to be one universe where a civilization got so advanced they could travel through the multiverses and they found us, turns out we're that civilization and came back to see our past selves, so is it a matter of time till they get here, have they already been here and we just don't know Infinite possibilities keep in my mind what I just said has happened if this theory is correct

[wonder]

Brian Greene is one the genius in explaining difficult concepts, what amaze me is how he explains it with a lot of passion.

[pabrielgomez]

My favorite type of multiverse is the ultimate multiverse.

The graphic art is gorgeous props to the artist! Also I watched it again but then with music playing over it!

[wildman]

And there's probably a million other "me's" in other universes thinking: "I was told there would be no math..."

[michaelb]

Scientists are the real "rock stars"! I freaking LOVE these videos!

[ikechukwuagwu]

Why is it that other universes are always depicted in the shape of spheres? What if the same laws of gravity that applies in this universe that works to shape everything into a sphere doesn't work in other universes? Does that mean that other universes could have alternative shapes than the ones we're always shown?

[noobtopro]

Everything makes so much sense now.!! My life is not limited to single outcome, i can have infinite possibilities and that is all related to my visualization and belief, if i can see something in my imagination, that means it exists in some parallel universe and hence i can live that possibilitiy with immense belief. <3

Experience is the best teacher in my words

[grayfoxart]

Its quite incredible how people ties consciousness with the universe. Heck we don't even know what a conciousness is.
