Dark Energy and the Runaway Universe

World-renowned astronomer and prize-winning professor of astronomy at the University of California, Berkeley, Alex Filippenko, explores some of the mysteries of the universe at a special lecture at the Santa Barbara Museum of Natural History. Filippenko discusses observations of very distant exploding starts called super-novae that provide intriguing evidence that the expansion of the universe is now speeding up. Over the largest scales of space, the universe seems to be dominated by a repulsive "dark energy" of unknown origin, stretching the very fabric of space itself faster and faster with time.

@konman001 so we should stop trying to fix the worlds problems and just hope that some collective delusion is true? the percentage of people with access to the tools that science have provided live longer and healthier, are more productive and experience less war. You are just biased towards the 'earth is hell' view, that xians need in order to feel good about going to heaven. go on waste your life. Atheists will be the ones laughing at you in the end (figurativly speaking)

@tristbjorn: You go from "cosmic inflation" to a long pause and then a gradual accelleration. That requires a far more robust theory behind it than we have here. The implications are just as I stated, otherwise. The missing explanations at this point outweigh the speculative theorizing.

@RyuDarragh how did you get to the laws of physics are variable? There is nothing in the current view of the universe that would suggest otherwise. You should probably go through it again to understand it.

@wertyh11 You have no idea about what these people actually contribute with. What have you done, that are so fantastic, that we should stop spending money on scientific progress?

[tristbjorn]

@kuteneh2000 He explained it when he talked about the universe being flat and the total expected amount of energy in the universe thus possible to know. Watch the Lawrance Krauss 'a Universe from nothing' where it's explained further.

@BuddyJesusSmokes so your solution to believing in something that is constantly proved wrong, is that all those who prove you wrong should kill them selves? Your intelectual capacity is astonishing.

[tristbjorn]

@konman001 And it's so smart to follow some old goatherders book. Wouldn't you laugh if people worshipped Tolkiens books as the truth about the world? Religion is for simple minds that crave simple answers.
