In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the very early universe. Following the inflationary period, the universe continued to expand, but at a slower rate.

2021年1月8日 · Inflation took place long before our earliest snapshot of the universe, the cosmic microwave background (CMB). This dramatic process magnified local density fluctuations and equalized the...

According to the theory of inflation, the early Universe expanded exponentially fast for a fraction of a second after the Big Bang. Cosmologists introduced this idea in 1981 to solve several important problems in cosmology.

2024年10月22日 · Around 13.8 billion years ago, the universe expanded faster than the speed of light for a fraction of a second, a period called cosmic inflation. Scientists aren’t sure what came before inflation or what powered it.

Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

2025年1月21日 · Cosmology - Inflation, Expansion, Big Bang: One of the more enduring contributions of particle physics to cosmology is the prediction of inflation by the American physicist Alan Guth and others. The basic idea is that at high energies matter is better described by fields than by classical means.

1 天前 · The SPHEREx space telescope will shed light on a cosmic phenomenon called inflation In the first billionth of a trillionth of a trillionth of a second after the big bang, the universe increased in ...

2 天之前 · SPHEREx is a groundbreaking NASA telescope that will map the entire sky in infrared, revealing insights into cosmic inflation, galaxy formation, and the ingredients of life in space. By measuring the total glow of the universe and pinpointing key molecules in our galaxy, it will complement existing telescopes with a broad, all-encompassing view ...

What is Cosmic Inflation? Cosmic inflation is the theory that the universe underwent a brief period of exponential expansion a small fraction of a second after the Big Bang singularity.

2022年3月15日 · Cosmic inflation provides a window to the highest energy densities accessible in nature, far beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the...
