Using the gravitational anomaly method proposed by Robinson and Wilczek, Hawking radiation from the apparent horizon of a Vaidya black hole is calculated. The thermodynamics can be built successfully on the apparent horizon. In the meantime, when a time-dependent perturbation is given to the ...
How does Hawking radiation escape a black hole? Do black holes come from entropy and quantum tunneling? Are black holes made of baryonic matter? Does space-time spin? What is the black hole information paradox? Does dark matter speed the expansion of the universe?
And even if they do exist, they may be incredibly unstable. According to astrophysicist Stephen Hawking, wormholes may exist in quantum foam, the smallest environment in the universe. Here, tiny tunnels constantly blink in and out of existence, momentarily linking separate places and time like ...
Q: Do time and distance exist in a completely empty universe? Q: Why is it that photographs of wire mesh things, like window screens and grates, have waves in them? Q: How does quantum physics affect electron configurations and spectral lines? Q: Is it possible for an atomic orbital to...
the doctrine that only mental contents exist: reality is mind-dependent. One potential source of confusion of contemporary scientific idealism with traditional philosophical idealism is the use by inferential realists in the theory of perception of the term "world-simulation". The mind-dependence of ...
What makes the discovery even more exciting is that the newfound terrestrial planet is about the size of Earth and lies in Proxima Centauri's "habitable zone" — the range of distances where liquid water could exist on a world's surface. So it's a good candidate for powerful telescopes, ...
Alternatively, they may be interpreted as black hole relics [32] formed at the end of Hawking evaporation [33,34]. If they exist, such relics represent unique quantum and gravitational states, in which the Schwarzschild and Compton radii coincide. For m ≥ m P ′ , the quantum EOM may ...
One such structure could emit a Hawking-like flux if it were continuously and asymptotically approaching its Schwarzschild radius (without crossing it) [99], or if it were pulsating in Universe 2016, 2, 7 21 of 30 a close to free-fall manner [100]. Should this radiation exist, it would...
During the quantum phase, states sharp in ΛΛ did not know the time. The Universe was not timeless, as in canonical quantum gravity: time did exist, but was not determinable. A quantum rewinding Chern–Simons time is therefore possible....
