Relativity of simultaneity. Einstein's famous train thought experimnent. The video shows the point of view of an observer on the embankment (red line) and that of a passenger at the centre of the relativistically moving train (brown line). The two observers disagree on wether or not the lightening strikes are simultaneous or not.
Scientific Miracles Of The Nobel Quran 02 (The Creation of the Universe) big bang theory Islam is the Only TRUTH Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past.[25] This singularity signals the breakdown of general relativity. How closely we can extrapolate towards the singularity is debated—certainly not earlier than the Planck epoch. The early hot, dense phase is itself referred to as "the Big Bang",[notes 2] and is considered the "birth" of our universe. Based on measurements of the expansion using Type Ia supernovae, measurements of temperature fluctuations in the cosmic microwave background, and measurements of the correlation function of galaxies, the universe has a calculated age of 13.73 ± 0.12 billion years.[26] The agreement of these three independent measurements strongly supports the ΛCDM model that describes in detail the contents of the universe. The earliest phases of the Big Bang are subject to much speculation. In the most common models, the universe was filled homogeneously and isotropically with an incredibly high energy density, huge temperatures and pressures, and was very rapidly expanding and cooling. Approximately 10−37 seconds into the expansion, a phase transition caused a cosmic inflation, during which the universe grew exponentially.[27] After inflation stopped, the universe consisted of a quark-gluon plasma, as well as all other elementary particles.[28] Temperatures were so high that the random motions of particles ...

Sarah Jessica Parker Sarah Jessica Parker (born March 25, 1965) is an American film, television and theatre actress, and producer. She is best known for her leading role as Carrie Bradshaw on the HBO television series *** and the City, for which she won four Golden Globe Awards, two Screen Actors Guild Awards and two Emmy Awards. She played the same role in the 2008 feature film version of the show, *** and the City: The Movie and its sequel, which is scheduled to open in 2010. Parker is also known as a film actress, in addition to television and theatre, has appeared in films like Honeymoon in Vegas (1992), Hocus Pocus (1993), along with co-star Bette Midler, Mars Attacks! (1996), State and Main (2000). More recently, Parker starred in The Family Stone (2005) and Smart People (2008). Parker attended the School for Creative and Performing Arts in Cincinnati, the School of American Ballet, Dwight Morrow High School and the Professional Children's School, Hollywood High School in Los Angeles, California. Parker and four siblings appeared in a staging of The Sound of Music at the Muny in St. Louis, MO, and Parker went on to the new 1977-81 Broadway musical Annie — first in the small role of "July" and then succeeding Andrea McArdle and Shelley Bruce in the lead role of the plucky Depression-era orphan, beginning March 6, 1979. Parker held the role for a year. In 1982, Parker was cast as the co-lead of the CBS sitcom Square Pegs. The show lasted one season before being cancelled by the network ...
The Big Bang in 1 minute and 44 seconds Song by Bad religion Written by Greg Graffin & Brett Gurewitz Extrapolation of the expansion of the Universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past. This singularity signals the breakdown of general relativity. How closely we can extrapolate towards the singularity is debated—certainly not earlier than the Planck epoch. The early hot, dense phase is itself referred to as "the Big Bang", and is considered the "birth" of our Universe. Based on measurements of the expansion using Type Ia supernovae, measurements of temperature fluctuations in the cosmic microwave background, and measurements of the correlation function of galaxies, the Universe has a calculated age of 13.73 plus or minus 0.12 billion years. The agreement of these three independent measurements strongly supports the ΛCDM model that describes in detail the contents of the Universe. The earliest phases of the Big Bang are subject to much speculation.

LearningMeasure Episode 7: Radar and Relativity (Complete) In this episode the topic is using radar to measure position and velocity. The basics of radar are discussed, and then a derivation of the Doppler shift formula is presented. First a more classical version, and then a discussion about relativity theory and the relativistically correct Doppler shift formula. This follows from one of the postulates of relativity theory that the speed of light is the same for all observers. Saved from Google Video.
algekalipso: @kharmabum You are making me think with that. :D I'm thinking relativistically, time and interaction with other relevant events both matter
brainsmatter: I need to relativistically find a low-energy way of stopping time so I don't turn another year older.
