the universe is expanding. It is not the galaxies themselves that are expanding but the space between them. What is happening is analogous toinflating a balloon with small coins attached to its surface. The coins behave like galaxies: although they do not expand, the space between them does....
creating the (flat) arena wherein the net energy in the universe is zero. Indeed, Krauss states 'But you can still ask, Where does all the energy come from to keep the density of energy constant during inflation, when the universe is expanding exponentially'?
Why does our universe look the way it does? In particular, why do we only experience three spatial dimensions in our universe, when superstring theory, for instance, claims that there are ten dimensions — nine spatial dimensions and a tenth dimension of time?
space is this genetic tendency to expand wherever possible. Nearly every successful civilization has explored because by doing so any dangers in surrounding areas can be identified and prepared for. Without knowledge we may be completely destroyed by the danger. With knowledge we can lessen its ...
Why does the author refer to “inflating a balloon with small coins attached to its surface”? A. To help explain how the universe can expand while the galaxies remain the same size B. To imply that the universe must eventually stop expanding C. To support the statement that most stars ...
According to the predominant cosmological model – theLambda Cold Dark Matter(LCDM) model – the Universe will eventually expand to the point that theCosmic Microwave Background(CMB) will recede into the radio end of the spectrum and that anything beyond our galaxy will be beyond the event hor...

But, he says, “what does it mean to predict something if it predicts everything?” Such a theory can’t be tested—or potentially falsified—and thus isn’t a useful scientific theory. The multiverse, he says, is a “multi-mess.” [Here’s why you don’t want to get bitten by a...
as he does now, obsess over his philosophy of humor per se. True, he might reply “Haha awesome :)” when tagged in a flattering meme about himself, and he never quite grasped the vernacular of comedy — he oncecalleda Liam Neeson cameo in the sitcomLife’s Too Shorta “ske...
