Infinite Worlds: A Journey through Parallel Universes
About | Information | History | Online | Facts | Discovery
The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom discuss and debate this controversial implication of forefront research and explore its potential for redefining the cosmic order. Moderated by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky. Subscribe to our YouTube Channel for all the latest from WSF.

i love you brian greene and the robot brain science holla

the number of photos and videos linked to the meta data of every photon

Why hasn't anyone come to the realization that the opposite of gravity is levity? The multiverse and the very early universe are funny. Funny peculiar however, not funny ha-ha.
+TheOnewhoKnocks, I don't like the two-dimensional analogy. I think it oversimplifies things too much and often fails to get the basic idea across. If you are capable of thinking in four dimensions, what mass (matter + energy) does is perhaps better visualized as pulling the fabric of spacetime in towards the center of the mass from all directions. What many fail to point out in the two dimensional analogy is that the curvature caused by mass (gravity) creates a third dimension that allows objects to continue traveling in a straight line from their perspective. Even light bends when it passes close enough to the Sun (a fact that has been observed and is what confirmed Einstein's theory was correct and Newton's was not) but from the perspective of an individual photon, it travels in a straight line. The moon "thinks" (wrong word but I hope you get what I mean) it is traveling in a straight line as it orbits the Earth but the curvature of spacetime caused by the mass of the earth bends the area around it enough to keep the Moon in orbit. An obvious question is "why doesn't the moon fall toward the Earth and why doesn't the Earth fall towards the Sun?" The answer is that they would if there were no other forces at work, because there is a very (very, very, very) small friction encountered as objects travel through "empty" space (because it is not completely empty). In the case of the Earth-Moon system, the moon is actually moving away from the Earth, in part because it formed with enough velocity that it is on the verge of escaping the Earth's gravity. There are other reasons that I am not currently well enough versed in so I won't try to explain them. Looking at the Earth-Moon system and the sun, one factor that keeps us from falling toward the Sun as we push through the solar wind is the fact that the Sun is constantly losing mass (that very solar wind that slows us down is some of the mass that the Sun has lost).
Sorry about being so long winded, I tend to do that. It is not an easy thing to understand when trying to visualize it in real space time and with more that just gravity involved. -
Modern physics to have lost interest in the real world

Great guests, great panel, annoying as hell moderator.
-
The British philosopher have really crazy ideas. Maybe crazy.

Is this back up by math? If not even a child could do it. With all respect of course. They know their stuf. But on this subject its just guesswork.

Please go to YouTube: “Norma, I now know what happens if mass exceeds the speed of light –“
The mathematical model for Infinity is 3 lines in an x,y,z relationship interesting at “0” with “1” a unit of measurement in all directions away from “0”. Therefore, “0” can never be equal to “1”.
However, the Mathematical Symbol for “Infinity” is two circles joined at 0=1. If our universe was formed by 2 equal masses colliding at the speed of light [E=Mc2= (1/2Mc) ><(1/2Mc)], a finite number of vibrating energy strings of equal length (1 [positive charge] on one end and 0 [negative charge] on the other end) radiating out in all directions at the speed of light to resemble a sphere. Each string forms a circle of vibrating energy joined at 0=1 with a diameter of 1 unit of measurement (1 Lightfoot = 1/pi). Some of these smallest energy partials in the universe will travel out to a maximum radius and return back to the original point of collision. Also, as the partials were radiating out, the particles vibrating at the same frequency started forming electrons, neutrons and protons, thus forming all the physical universe. Therefore, lines do not exist within the limits of the universe, just the line segment that forms the Diameter and Circumference of a circle. Since, infinity minus infinity equals Pi, with the diameter of the smallest particle a unit of 1 lightfoot , there is no need for a ”line of infinite length" in the physical universe. -
WTF was up with that Black Eyed Peas intermission?

Great talk, and I love how the moderator kept it light mooded and funny, while staying on topic and keeping it interesting.
-
This would be great if I had a joint to smoke ...
-
rabbit hole stuff, if this was a simulation, then it could stand to reason that the admin might suggest the bubble universes, so we the participant would consider our self confined by the speed limit of light
-
I have had lots of weird and down right strange dreams, but there is all ways that dream that seams so real that it is more like an alternate existence, like as if you your self, have jumped from one existence to the next and back like as if your sharing prospective, why I bring dreams up is if all things at one point was in the same place, then all things must already be entangled

The more man learns the more he becomes a fool thinking he understands the great mysteries which are hidden from mankind while ignoring the obvious.

it seems to end up sounding like an intelligent way of saying what came first the chicken or the egg !!!
-
i dont know wtf is going on here

bazinga

Hehehe, Newton was talking about crow shit dropping, not apples :-)
-
forger the multiverse (many universes together)
think bigger... what about many multiverses... bubbles with universes inside... I would call that a Megaverse lol or omniverse hahaah
