Storyline Edit. They are colleagues, best friends, and roommates, although in all capacities their relationship is always tested primarily by Sheldon's regimented, deeply eccentric, and non-conventional ways. They are also friends with their Cal Tech colleagues mechanical engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali. The foursome spend their time working on their individual work projects, playing video games, watching science-fiction movies, or reading comic books.
As they are self-professed nerds, all have little or no luck with women. When Penny, a pretty woman and an aspiring actress from Omaha, moves into the apartment across the hall from Leonard and Sheldon's, Leonard has another aspiration in life, namely to get Penny to be his girlfriend. Smart Is The New Sexy. Did you know Edit. Trivia Most of the time, Leonard Johnny Galecki has no lenses in his glasses.
Goofs In one episode, Sheldon states that pets are banned under the roommate agreement, but in another he adopts 25 cats. But it's regularly shown that Sheldon uses the roommate agreement to his own advantage, sometimes unaware, but more often completely ignoring, how it affects Leonard. Quotes [repeated line when someone accuses Sheldon of being crazy] Sheldon : I'm not crazy.
Crazy credits One of the final cards to appear in the credit sequence is the vanity card for Chuck Lorre Productions. Because we can't see it directly, scientists have been trying to figure out how to "see" the Big Bang through other measures.
In one case, cosmologists are pressing rewind to reach the first instant after the Big Bang by simulating 4, versions of the current universe on a massive supercomputer. With what is known about the universe today, the researchers on this study compared their understanding of how gravitational forces interacted in the primordial universe with their thousands of computer-modeled universes.
If they could predict the starting conditions of their virtual universes, they hoped to be able to accurately predict what our own universe may have looked like back at the beginning.
In a study, researchers did so by investigating the split between matter and antimatter. In the study, not yet peer-reviewed, they proposed that the imbalance in the amount of matter and antimatter in the universe is related to the universe's vast quantities of dark matter, an unknown substance that exerts influence over gravity and yet doesn't interact with light. They suggested that in the crucial moments immediately after the Big Bang, the universe may have been pushed to make more matter than its inverse, antimatter, which then could have led to the formation of dark matter.

Planck's observations, first released in , mapped the CMB in unprecedented detail and revealed that the universe was older than previously thought: The research observatory's mission is ongoing and new maps of the CMB are released periodically.
Related: How old is the universe? The maps give rise to new mysteries, however, such as why the Southern Hemisphere appears slightly redder warmer than the Northern Hemisphere. Examining the CMB also gives astronomers clues as to the composition of the universe. Researchers think most of the cosmos is made up of matter and energy that cannot be "sensed" with our conventional instruments, leading to the names "dark matter" and "dark energy. While astronomers study the universe's beginnings through creative measures and mathematical simulations, they've also been seeking out proof of its rapid inflation.
They have done this by studying gravitational waves , tiny perturbations in space-time that ripple outwards from great disturbances like, for instance, two black holes colliding, or the birth of the universe. According to leading theories, in the first second after the universe was born, our cosmos ballooned faster than the speed of light. That, by the way, does not violate Albert Einstein's speed limit. He once said that light speed is the fastest anything can travel within the universe — but that statement did not apply to the inflation of the universe itself.
As the universe expanded, it created the CMB and a similar "background noise" made up of gravitational waves that, like the CMB, were a sort of static, detectable from all parts of the sky. Those gravitational waves, according to the LIGO Scientific Collaboration , produced a theorized barely-detectable polarization, one type of which is called "B-modes. But by June, the same team said that their findings could have been altered by galactic dust getting in the way of their field of view.
That hypothesis was supported by new results from the Planck satellite. By January , researchers from both teams working together "confirmed that the Bicep signal was mostly, if not all, stardust," the New York Times said. However, since then gravitational waves have not only been confirmed to exist, they have been observed multiple times. These waves, which are not B-modes from the birth of the universe but rather from more recent collisions of black holes, have been detected multiple times by the Laser Interferometer Gravitational-Wave Observatory LIGO , with the first-ever gravitational wave detection taking place in As LIGO becomes more sensitive, it is anticipated that discovering black hole-related gravitational waves will be a fairly frequent event.
The universe is not only expanding, but expanding faster. This means that with time, nobody will be able to spot other galaxies from Earth, or any other vantage point within our galaxy.
What that means is that even light won't be able to bridge the gap that's being opened between that galaxy and us. There's no way for extraterrestrials on that galaxy to communicate with us, to send any signals that will reach us, once their galaxy is moving faster than light relative to us.

In the "multiverse" model, different universes would coexist with each other like bubbles lying side by side. The theory suggests that in that first big push of inflation, different parts of space-time grew at different rates.
This could have carved off different sections — different universes — with potentially different laws of physics. Guth is not affiliated with that study. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously.
While we can understand how the universe we see came to be, it's possible that the Big Bang was not the first inflationary period the universe experienced. Some scientists believe we live in a cosmos that goes through regular cycles of inflation and deflation, and that we just happen to be living in one of these phases.
The name "Big Bang Theory" has been a popular way to talk about the concept among astrophysicists for decades, but it hit the mainstream in when a comedy T. Running for episodes over 12 seasons, the show "The Big Bang Theory" followed the lives of a group of scientists, which included physicists, astrophysicists and aerospace engineers.
The show explores the group's nerdy friendships, romances and squabbles. Its first season premiered on Sept.
