- TCrB Charts and Photometry Tables (aavso.org)
Finding charts with comparison stars and related multicolor photometry tables for different scales of T CrB have been created for your convenience. The comparison star magnitudes reflect the revision of 02 July 2024 AND the July 16 re-introduction of the 102 comparison star on the B and D charts.
- Heat death of the universe (Wikipedia)
The heat death of the universe (also known as the Big Chill or Big Freeze) is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy. Heat death does not imply any particular absolute temperature; it only requires that temperature differences or other processes may no longer be exploited to perform work. In the language of physics, this is when the universe reaches thermodynamic equilibrium. The Heat Death theory has become the leading theory in the modern age with the fewest unpredictable factors.
