Small blue galaxy could shed new light on Big Bang,IU astronomers say
Small blue galaxy Big Bang,IU astronomers
2016/5/19
A faint blue galaxy about 30 million light-years from Earth and located in the constellation Leo Minor could shed new light on conditions at the birth of the universe.Astronomers at Indiana University...
Pre-big bang collapsing universe from modern Kaluza-Klein theory of gravity
Pre-big bang collapsing universe modern Kaluza-Klein theory gravity
2011/10/18
We study the collapse of the universe described by a scalar field spherically symmetric collapse of a system described by a massless scalar field from a 5D Riemann-flat canonical metric, on which we m...
Standard Big-Bang Nucleosynthesis up to CNO with an improved extended nuclear network
Big-Bang Nucleosynthesis improved extended nuclear network
2011/9/28
Primordial or Big Bang nucleosynthesis (BBN) is one of the three strong evidences for the Big- Bang model together with the expansion of the Universe and the Cosmic Microwave Background radiation. In ...
Circular patterns within the cosmic microwave background suggest that space and time did not come into being at the Big Bang but that our universe in fact continually cycles through a series of "aeons...

Big Bang conditions the Large Hadron Collider High Energy Physics
2010/10/13
Since December, the Large Hadron Collider (LHC) has been smashing particles together at record-setting energy levels. Physicists hope that those high-energy collisions could replicate the conditions s...
Using Big Bang Nucleosynthesis to Extend CMB Probes of Neutrino Physics

2010/3/22
We present calculations showing that upcoming Cosmic Microwave Background (CMB) experiments will have the power to improve on current constraints on neutrino masses and provide new limits on neutrino ...
局爆宇宙学（Local Bang）是与大爆炸宇宙学（Big Bang）相对立的学说。我们认为宇宙是无限的，在时间和空间上没有起点。局爆宇宙学假定，星系团内的致密暗物质在碰撞时或者致密暗星体在晚年时会发生爆炸，即宇宙中的局部性爆炸（Local Bang）。我们接受与宇宙学相关的所有实验观察事实，包括河外星系光谱线的红移, 3K微波背景辐射等。我们采用局爆宇宙学的理论来解释这些观察事实。 我们认为伽玛...
