Did Time Begin? Will Time End?: Maybe the Big Bang Never by Paul H Frampton

By Paul H Frampton

Even if everyone seems to be acquainted with the concept that of time in way of life and has most likely given inspiration to the query of the way time started, most modern clinical advancements during this box haven't been obtainable in an easy comprehensible shape. This booklet is critical because it offers to readers present rules in regards to the position of time in theoretical cosmology. contemporary observational discoveries, specially that the growth price of the universe is accelerating, have revolutionized the certainty of the power content material of the universe (only a small fraction of approximately 4 percentage is basic topic; the remaining is ready twenty-four percentage darkish topic and seventy-two percentage darkish energy). hence the darkish part of the universe, particularly darkish strength, results in new chances for the start and finish of the universe. This ebook emphasizes the proposal of entropy and describes the way it is theoretically attainable that the universe may possibly result in a finite time. even though this publication doesn't offer definitive solutions to the questions posed within the identify, it offers twenty first century medical wisdom, written via a number one theoretical physicist, that would greater permit an educated reader to debate the character of time.

Example text

Such hubris was short-lived. In the early part of the 20th century, two serious limitations to the applicability of the foundations 34 Did Time Begin? Will Time End? of theoretical physics were found, both of which led to revolutionary advances. The first limitation was associated with the concept of the aether. Aether was invented as a hypothetical medium through which electromagnetic waves could propagate. It seemed at the time inconceivable that such a wave could travel through vacuum and would need aether as an analog of the air through which sound waves propagate.

To be so close to flat now, the density one second after the Big Bang must have equalled the critical value to one part in a hundred trillion. 7 billion years. A priori both of these circumstances are exceptionally unlikely. This latter unlikeliness can 26 Did Time Begin? Will Time End? be compared to balancing a pencil on its sharpened point and finding it still so balanced a very long time later: any physicist or non-physicist would demand an explanation. The appropriate modification of the Big Bang model is suggested by the study of theories for particle physics at high energies.

The inflationary period is where the scale factor defining the size of the universe increases by at least twenty-eight orders of magnitude. If the expansion is exponential in time, it implies that the Hubble parameter is constant during inflation. The Hubble parameter is the ratio of the time derivative of the scale factor to the scale factor itself. A property of an exponential function is that its derivative equals to itself. The comoving visible horizon decreases as the inverse of the scale factor which means that the fluctuations go outside of the horizon during inflation.
