No - Like black holes, white holes have properties like mass, charge, and angular momentum. Consequently a white hole will attract matter like any other mass. However any objects falling towards a white hole would never actually reach the white hole's event horizon, as it is the reverse of a black hole. In example, while a black hole can be entered from the outside, nothing, including light, has the ability to escape. Conversely while a white hole attracts matter, nothing, including light, has the ability to enter from the outside (e.g. matter and light have the ability to escape).
Note: The prevailing hypothesis is that there are no lone white holes. Rather a white hole, in general relativity, is a hypothetical region of SpaceTime which appear in the theory of eternal black holes. In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past. However, this region does not exist for black holes that have formed through gravitational collapse, nor are there any known physical processes through which a white hole could be formed.
No the singularity is at the core of the black hole.
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
Into the black hole's singularity.
All black holes have a singularity at their center. A singularity in a black hole is a location where the density of matter is infinite, at such a location physics equations give incomprehensible nonsense answers. (singularities occur in pure mathematics also, where for various reasons usable answers cannot be obtained from the equations: e.g. singular matrices)in Static and Charged black holes this singularity is an infinitesimal point.in Rotating black holes this singularity is a rapidly spinning ring.
To its center of mass (the singularity)
No the singularity is at the core of the black hole.
No, they are not the same. A singularity would be inside a black hole.
We do not know how the universe began, or what the exact sequence of events were.
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
A white dwarf is a white hot solid ball of nickel-iron alloy, a black hole is an infinitesimal singularity of infinite density surrounded by total emptiness.
Into the black hole's singularity.
A singularity is at the centre of a black hole.
singularity
Not exactly. The singularity is in the center of the black hole. Somewhat like a peach pit is in the center of the peach but it isn't the peach but part of it.
Yes, according to current scientific understanding, every black hole is believed to contain a singularity at its core.
Yes
