Há 10 horas · Evidence for a proposition is what supports the proposition. It is usually understood as an indication that the supported proposition is true. What role evidence plays and how it is conceived varies from field to field. In epistemology, evidence is what justifies beliefs or what makes it rational to hold a certain doxastic attitude.
Há 10 horas · v. t. e. The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1] With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
Há 10 horas · The solar model that was constructed out of these studies indicated that the solar neutrino problem discussed in Chap. 9 is actually a problem related to particle physics. Efforts to observe solar-like, i.e. p-mode vibrations in other stars succeeded for the first time in 1991 when the sub-giant Procyon was found to pulsate with a mean frequency 0.9 mHz and rms amplitude 2.5 ms \(^{-1}\) [ 7 ].
