Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion. A material containing such unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission.
<u>Answer:</u>
The<u> deductive reasoning</u> is an inquiry process that begins with a theory, prediction, or general principle that is then tested through data collection.
<u>Explanation:</u>
Deductive reasoning or logic is the reasoning mechanism from one or more statements in order to draw a logically definite inference. Deductive reasoning moves in the same direction as conditional reasoning and connects assumptions to judgments.
Both inductive and deductive reasoning aspire to build a reasonable argument. Inductive reasoning thus jumps from specific instances to a generalized conclusion, while deductive reasoning steps from generalized concepts, which are regarded to be accurate to a real and specific assertion.
The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. Based on available observational evidence, deciding the fate and evolution of the universe have now become valid cosmological questions, being beyond the mostly untestable constraints of mythological or theological beliefs. Many possible futures have been predicted by different scientific hypotheses, including that the universe might have existed for a finite and infinite duration, or towards explaining the manner and circumstances of its beginning.
