Sixth Alexander Friedmann International Seminar on Gravitation and Cosmology Scientific Motivation The scopes of the Friedmann Seminars are traditionally rather wide and include selected topics on classical gravity, observational cosmology, quantum effects in curved space-time, and quantum gravity. Nowadays, thanks to progress in modern astronomy, accurate observations (COBE, Boomerang, WMAP,Ö) enable us to test any theory of the primordial universe. For example, multidimensional gravity and cosmology is a candidate issue for understanding the birth of the universe. Over the past years different unified schemes with extra dimensions have been proposed. Other highlights are on the dark matter, the cosmological constant and the modern inflationary scenarios.

Verlag Quiz Wer war es? Archiv ... Mai 2001 Alexander Friedmann: Die Welt als Raum und Zeit Portrait Der gesuchte Wissenschaftler war Alexander Friedmann (1888-1925). Mit den Annahmen der globalen Isotropie und Homogenität des Universums konnte er die allgemeinen Einsteinschen Feldgleichungen der Gravitation auf eine Form reduzieren, die einen einfachen Skalenfaktor, die "Größe des Universums", als Funktion der Zeit beschreibt. Abhängig von der Materiedichte fand er Lösungen, die ein expandierendes oder oszillierendes Weltall beschreiben. Der Ansatz, der in der Einsteinschen Theorie ein homogenes und isotropes Universum beschreibt, wird als Friedmann-Robertson-Walker-Metrik bezeichnet. Sie ist die theoretische Grundlage des modernen Urknall-Modells. Die hieraus folgende Gleichung für den Skalenfaktor ist heute als "Friedmann-Gleichung" bekannt. Literatur und Links: Es gibt bisher fast keine deutschsprachige Literatur zu Alexander Friedmann - der einleitende Text von Georg Singer zur deutschen Ausgabe der " Die Welt als Raum und Zeit " schließt hier eine große Lücke.

EL UNIVERSO DE FRIEDMANN A principios de los años 20, el físico y matemático ruso Alexander Friedmann fue la primera persona que abrazara la idea de que las ecuaciones de la teoría general de la relatividad de Einstein llamaban a un Universo en movimiento. Einstein (y la mayoría de los otros científicos, de esa materia) creyeron que el Universo era estático, y él modificó sus ecuaciones incluyendo una constante cosmológica para mantener el Universo estático. Friedmann hizo dos asunciones simples sobre el Universo: que cuando es visto a grandes escalas, aparece el mismo en cada dirección y en cada localización. De estas asunciones (llamadas el principio cosmológico) y de las ecuaciones de Einstein, él desarrolló el primer modelo de un Universo en movimiento. El Universo de Friedmann comienza con una gran explosión y se continúa ampliando en la etapa actual. Pero después de un período de tiempo suficientemente largo, la atracción gravitacional mutua de toda la materia retardará la extensión hasta detenerse. El Universo entonces, comienza a caer adentro de sí mismo, jugando de nuevo la extensión, pero al revés. Toda la materia se derrumba eventualmente dentro de una singularidad, en la que los físicos tiene el gusto de llamar el Big Crash (Gran Contracción). Aunque Friedmann encontró solamente una solución, llamada un Universo cerrado porque el tamaño del Universo es finito, dos soluciones similares existen. En un Universo abierto, aquí no hay bastante materia para detener la expansión. Las galaxias continúan apartándose una de otra, aunque más lentamente con el tiempo. Todas las estrellas eventualmente se apagarán, y el Universo se convierte en frío y oscuridad. El intermedio entre el Universo abierto y cerrado es el Universo plano. En este caso, el Universo se amplía por siempre, pero la velocidad en la cual las galaxias se separa eventualmente decae hasta cero. ¿En qué clase de Universo vivimos? Las observaciones de la densidad del Universo deben decirnos en cual de las tres posibilidades. Hasta ahora no contamos con suficiente evidencia para decir si es cerrado, abierto y plano.
