The leading theoretical explanation is a lightning-fast burst of accelerated expansion of space in the first fraction of a second of the Universe — called cosmic inflation. This expansion pushed apart regions of space that were in causal contact — and so were smoothed out.
We study physics, build models and propose observables for the primordial universe using quantum field theory, general relativity and/or string theory, and test them with data from astrophysical observations. Signals from pimoridal standard clocks encode the cause of the Big Bang.
Jan 17, 2017 · The most popular theory of our universe's origin centers on a cosmic cataclysm unmatched in all of history—the big bang.
Apr 19, 2019 · The primordial universe was not entirely uniform. Quantum fluctuations became the seeds of the large-scale structure of today's universe and one key source of information physicists rely on to...
The book The Five Ages of the Universe discusses the history, present state, and probable future of the universe, according to cosmologists' current understanding. The book divides the timeline of the universe into five eras: the Primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era.
Apr 24, 2024 · Galaxy found napping in the primordial Universe. Observations have revealed a galaxy that stopped forming stars earlier than expected. This discovery offers clues about when the first galaxies...
About 13.8 billion years ago, the Big Bang gave rise to everything, everywhere, and everywhen—the entire known Universe. What caused the Big Bang? What happened that first moment at the beginning of the Big Bang? When did the first stars form?
What is the universe made of? Matter and energy are the two basic components of the entire Universe. An enormous challenge for scientists is that most of the matter in the Universe is invisible and the source of most of the energy is not understood. How can we study the Universe if we can’t see most of it? Our Work. 95%

Oct 20, 2008 · The primordial power spectrum revisited. Carlos Barceló. Andalusian Institute of Astrophysics (CSIC), Granada, Spain. October 20, 2008 • Physics 1, 31. The universe we see today is the result of mass-energy fluctuations during the rapid inflationary expansion that followed the big bang.
