Pie chart showing the fractions of energy in the universe contributed by different sources. Ordinary matter is divided into luminous matter (the stars and luminous gases and 0.005% radiation) and nonluminous matter (intergalactic gas and about 0.1% neutrinos and 0.04% supermassive black holes).
Under this scenario, dark energy would ultimately tear apart all gravitationally bound structures, including galaxies and solar systems, and eventually overcome the electrical and nuclear forces to tear apart atoms themselves, ending the universe in a "Big Rip". On the other hand, dark energy might dissipate with time or even become attractive.
In January 2023 it was decided by NASA and Roscosmos to replace MS-22 with Soyuz MS-23. As an interim measure in case of an emergency evacuation is required, the seat of NASA Astronaut Frank Rubio will be moved to Crew Dragon Endurance with SpaceX Crew-5 while Prokopyev and Petelin would return to earth on MS-22. Once MS-23 arrives, the seats ...
The Dark Energy Survey (DES) is an astronomical survey designed to constrain the properties of dark energy. It uses images taken in the near- ultraviolet , visible , and near- infrared to measure the expansion of the universe using Type Ia supernovae , baryon acoustic oscillations , the number of galaxy clusters , and weak gravitational lensing ...
This is a list of accidents and disasters by death toll. It shows the number of fatalities associated with various explosions , structural fires , flood disasters , coal mine disasters , and other notable accidents caused by negligence connected to improper architecture , planning , construction , design , and more.
Data centers could use up to 9% of total electricity generated in the United States by the end of the decade, more than doubling their current consumption, as technology companies pour funds into ...
Determine the high-energy behavior of gamma-ray bursts and transients. Probe dark matter (e.g. by looking for an excess of gamma rays from the center of the Milky Way) and early Universe. Search for evaporating primordial micro black holes from their presumed gamma burst signatures (Hawking Radiation component).
