In their interaction with earlier Greek philosophers who accepted this argument/dictum, Christian authors who accepted creatio ex nihilo, like Origen, simply denied the essential premise that something cannot come from nothing, and viewed it as a presumption of a limitation of God's power; God was seen as in fact able to create something out of ...
The process inverse to particle annihilation can be called matter creation; more precisely, we are considering here the process obtained under time reversal of the annihilation process. This process is also known as pair production , and can be described as the conversion of light particles (i.e., photons) into one or more massive particles .
Creatio ex nihilo is the doctrine that all matter was created out of nothing by God in an initial or a beginning moment where the cosmos came into existence. [13] [14] The third-century founder of Neoplatonism, Plotinus, argued that the cosmos was instead an emanation from God.
In standard cosmology, there are three components of the universe: matter, radiation, and dark energy. This matter is anything whose energy density scales with the inverse cube of the scale factor, i.e., ρ ∝ a −3, while radiation is anything whose energy density scales to the inverse fourth power of the scale factor (ρ ∝ a −4).
Microwave light seen by Wilkinson Microwave Anisotropy Probe (WMAP) suggests that only about 4.6% of that part of the universe within range of the best telescopes (that is, matter that may be visible because light could reach us from it) is made of baryonic matter. About 26.8% is dark matter, and about 68.3% is dark energy.
In astronomy, dark matter is an invisible and hypothetical form of matter that does not interact with light or other electromagnetic radiation.Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.
From this point on, and for several billion years to come, the presence of dark matter accelerates the formation of structure in the universe. In the early universe, dark matter gradually gathers in huge filaments under the effects of gravity, collapsing faster than ordinary (baryonic) matter because its collapse is not slowed by radiation ...
The scattered blue/violet light, appearing to come from all directions, is what makes the rest of the sky look blue.
