Black hole - Wikipedia
WEB1 day ago · Around the time of alignment, extreme gravitational lensing of the galaxy is observed. A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently ...

WEB21 hours ago · The difference between General Relativity and Teleparallel Gravity is the fact that General Relativity associates the curvature to the gravitational interaction, whereas in the Teleparallel Gravity the mathematical object associated to gravitational field is the torsion, whose field is the so called Weintzenb ̈ock connection.
Why do scientists claim time began with the Big Bang?
WEB21 hours ago · The singularity is not part of the mathematical description of space-time. So technically there is no point in space-time where time "began" since there is always a point closer to the singularity, but the singularity is not part of space-time, at least not in the standard describtion of general relativity.
[an Attempt To] go Beyond Einstein’s Constant Light Speed
WEB1 day ago · Indeed, improving physics theory by adding an appropriate mechanism is far-reaching; it could extend to Einstein general theory of relativity and quantum mechanical theory, which is then able to answer questions such as dark energy/matter, quantum entanglement, including Higgs. Finally it would pave the way to the theory of everything!

Dark matter could make our galaxy’s innermost stars immortal
WEB21 hours ago · They calculated stellar populations without and with the presence of dark matter. With dark matter, more massive stars experienced a lower dark matter density, and hydrogen in their core fused more slowly and their evolution was slowed down. But stars in a higher dark matter density region were changed significantly—they maintained …
Heavy Matter Universe | chrisperguidi
WEB21 hours ago · General relativity suggests that this information is lost, violating the fundamental principles of quantum mechanics!! We often imagine space-time as a flat fabric. However, we propose that the gravitational web that makes up Space-time behaves more like a dynamic, Viscous fluid than a flat fabric that is warped and distorted by …

WEB21 hours ago · For a δ Cephei star, the relationship can be approximated by a linear formula: M = a ⋅ log. . ( P) + b, where P is the period in days, and a and b are constants that have been determined from observations of Cepheids with known distances. Step 2/6. Use the given pulsation period to calculate the absolute magnitude (M) of the star.
