The ekpyrotic universe, or ekpyrotic scenario, is a cosmological model of the origin and shape of the universe. The ekpyrotic model of the universe is an alternative to the standard cosmic inflation model for the very early universe and is a precursor to, and part of, some cyclic models of the universe.
The ekpyrotic model came out of work by Neil Turok and Paul Steinhardt and maintains that the universe did not start in a singularity, but came about from the collision of two branes. This collision avoids the primordial singularity and superluminal expansion of spacetime while preserving nearly scale-free density fluctuations and other features of the observed universe. The ekpyrotic model is cyclic, though collisions between branes are rare on the time scale of the expansion of the universe to a nearly featureless flat expanse. Observations that may distinguish between the ekpyrotic and inflationary models include polarization of the cosmic microwave background radiation and frequency distribution of the gravitational wave spectrum.

My friends are such nerds, they got into a huge drunk argument about whether the we existed in an ekpyrotic universe or an exponential expansion universe.

Get the ekpyrotic universe mug.The actual name for what was previously known as Harvard University. This name applies when a male Norwegian nordic skier attends the University.
"I go to Haakvard University."
"You mean Harvard?"
"Well, when that Norwegian first year arrived, the university switched its name."

Get the Karen university mug.Every parent assumed that whatever alchemy of good genes and good credit had gotten his child a spot at the prep school was the same one that would land him a spot at a hyper-selective college. It was true that a quarter of the class went to the Ivy League, and another quarter to places such as Stanford, MIT, and Amherst. But that still left half the class, and I was the one who had to tell their parents that they were going to have to be flexible. Before each meeting, I prepared a list of good colleges that the kid had a strong chance of getting into, but these parents didn’t want colleges their kids had a strong chance of getting into; they wanted colleges their kids didn’t have a chance in hell of getting into. A successful first meeting often consisted of walking them back from the crack pipe of Harvard to the Adderall crash of Middlebury and then scheduling a follow-up meeting to douse them with the bong water of Denison.

Get the Denison University mug.All the kids think they are ultra-cool prodigy kids when in reality they are just immature awkward dorks who talk about their wooden duck sculptures and Greek Mythology fan fiction they have been writing. The teachers are kinda nice but the students always interrupt class to go off on a stupid, dorky tangent that wastes everyone's time. It's supposed to be a really good education but I feel like an idiot.
Some classmates will find your email or Skype handle and start messaging you, even when you very obviously hint that you aren't interested. No, I don't want to be friends with you, you seem weird.
