Like black holes, white holes have properties such as mass, charge, and angular momentum.They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole's event horizon (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in ...
Any event inside the black hole interior region will have a future light cone that remains in this region (such that any world line within the event's future light cone will eventually hit the black hole singularity, which appears as a hyperbola bounded by the two black hole horizons), and any event inside the white hole interior region will ...
For a simplified notion of a wormhole, space can be visualized as a two-dimensional surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance.
Oftentimes, Rovelli's book feels more like poetry than a science lesson as he explains black holes in striking detail and the theoretical concepts behind white holes.
The horizon r = 2GM and finite v (the black hole horizon) is different from that with r = 2GM and finite u (the white hole horizon) . The metric in Kruskal–Szekeres coordinates covers all of the extended Schwarzschild spacetime in a single coordinate system. Its chief disadvantage is that in those coordinates the metric depends on both the ...
The constant solution inside the event horizon is continued by a constant solution in a white hole. When the angular momentum is not zero we can replace the dependence on proper time by a dependence on the angle φ {\textstyle \varphi } using the definition of h {\textstyle h}
A massive blue hole just showed up near Mexico—and new lifeforms may be inside. What will scientists find 900 deep down?
To a lesser or greater extent, we all lie.And if you say that you don’t—somewhat ironically—you’d probably be lying. Spinning the truth is a common human behavior.
