No, it is NOT true. A black hole contains the densest matter in universe - infinite density. It's a black hole because the density is so high that even light cannot escape the gravitational field if it comes close enough. Regular stars bend light, black holes pull it in.

There is no object with no density: it would not be an object, it would be absolute empty space:

Density = mass / volume, 0 density = 0 mass / x volume : the other equation, 0 density = x mass / 0 volume has no answer in math, it's undefined. To get an answer that means something then the mass has to be 0, and any volume > 0. An object with 0 mass means no object, nothing.

What's inside a black hole?

there is nothing inside a black hole...a black hole's density is very large...so large all of our planets and stars including the sun's density would not even be 0.1% that of a black hole...a black hole is so strong, not even light can escape it...nothing can.

What is more dense black hole or star?

A black hole is more dense. In principle, the black hole exists all at one point. So its volume is zero, and its density is infinite.


What's at the bottom of a black hole?

A black hole isn't a hole as such. It is an extremely dense dead star that attracts all matter into a tiny singularity that has a massive density.


What is the singularity inside a black hole?

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.


What does a black hole do with what it suck in?

The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.


How many Planets in black hole?

There is simply no way of knowing this. Once matter is consumed into a black hole, it is converted into gravitational energy; a black hole's contents cannot be dissected and catalogued. However, according to an idea called the holographic principle, it may be possible for all the information contained within a black hole is encoded on its surface. If this proves to be true, then it might be possible to determine everything that has been sucked into the black hole.


Are black holes high density objects?

Yes and No - While the current measure for the mass of a black hole is based on an indirect measuring of the speed of the orbiting material, there is no direct measuring of the density of a black hole. Density is a concept involving mass divided by volume. While one can abstract the mass of a black hole, measuring the volume is a little tricky. We know there is a boundary at the Schwarzschild radius (Schwarzschild horizon) and this is also called the event horizon. Bascially, anything that happens beyond that point is unknown to us. Supermassive black holes have properties which distinguish them from lower-mass classifications. First, the average density of a supermassive black hole (defined as the mass of the black hole divided by the volume within its Schwarzschild radius) can be less than the density of water in the case of some supermassive black holes. This is because the Schwarzschild radius is directly proportional to mass, while density is inversely proportional to the volume. Since the volume of a spherical object (such as the event horizon of a non-rotating black hole) is directly proportional to the cube of the radius, the density of a black hole is inversely proportional to the square of the mass, and thus higher mass black holes have lower average density. To complicate things even more, space-time is highly distorted around a black hole, so even asking how big it is, adds further complexity to this answer. Nonetheless, black holes have a mass and size. However one can not know if the mass inside is accreted all at one point or more spread out and distibuted. It appears the inner dynamics of the black hole provide for a plasma like accretion disk, which that pretty much changes (or distorts) our traditional dimensional frame of reference. It could be that the black hole merely suspends acquire mass in a medium of energy state. Consequently this medium of energy may preclude its growth or shrinkage.


What happen to the meter that disappears into the black hole?

Matter that enters a black hole is thought to all be concentrated in a point of infinite density in the center of the black hole called the singularity. In a rotating black hole, the singularity's shape is shown to be ring-shaped. The nature of the matter at the singularity is not fully understood, since the current laws of physics are inadequate to describe it; but the mass itself appears to be conserved per known laws of conservation.

Can you make a black hole inside a black hole?

We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
