Why the universe probably is "flat"
Loading...
Uploaded by TorBarstad on Oct 12, 2010
Lawrence Krauss makes the case for a flat universe, where the total amount of mass-energy in the universe is and always has been zero.
I've made cuts also in the middle to get it under the 15 minute limit. The video can be seen in its entirety here: http://www.youtube.com/watch?v=7ImvlS8PLIo. Another version, a little shorter, and perhaps also better, can be seen here: http://www.youtube.com/watch?v=rdvWrI_oQjY&feature=related.

I love it how the biggest questions remained unanswered.

And physicist with their linguistic perspicacity. XD

@songteller we will never know the whole truth. but so far this theory best describes reality. Now it is up to the observers/experimentors to verify or confirm what the theorists came up with. This is how science works, and it is the only way forward. Yes, maybe we will have to rethink the concepts of dark matter or dark energy if they fail to find evidence for it at the LHC, but until then its the best we have. Bear in mind that quantum theory is responsible for the best predictions in physics

@BattleBits Gods are postulates as delineated by the faith-traditions that adhere to them. If you can describe X in terms that are applicable to humanity you can show a vanishingly small likelihood of any truth-value with science. As deities are, by definition, described by humanity, and as no faith-traditions contemplate cosmogenesis in this way, and indeed because the model shows no need for any external interference of any kind (yet described or otherwise), it is a consistent statement.

Are you sure the triangle is big enough to determine that the universe is flat? Great lecture. I'll second the "amazing" statement.

@eseskay99 I'm glad you found this interesting as I did. No, I know little more of this then I learned from the talk.
