Webbwith his “chaotic inflation” model [8]. This model still used a slow-roll potential, but did not require any particular level of pre-inflation energy density uniformity. Subsequent research has led to inflation becoming generally accepted as the strongest current candidate which offers solutions to the cosmological puzzles. WebbMed inflation menas vanligtvis att penningvärdet minskar. Den ursprungliga definitionen är "ökning av penningmängden [ 1] ". När penningmängden ökar kraftigt så minskar i regel penningvärdet. En effekt av inflation är att den allmänna prisnivån stiger, varför inflation ofta mäts med konsumentprisindex och uppfattas av många som ...

Webb20 apr. 2016 · The slow roll approximation simplifies the equations of motion and guarantees that inflation will occur. However, as the text you have quoted states, it is also possible to have inflation without resorting to the slow roll approximation.

WebbA slow roll is an aerobatic maneuver in which an airplane makes a controlled roll by rotating about its longitudinal axis. It is performed by rolling the aircraft at a constant rate, while manipulating the control surfaces to maintain level flight. dan snow tv presenter
