You are referring to a black hole.
A black hole
A cold object is more dense.
Objects can be made to float by reducing their overall density so that they become less dense than the fluid they are placed in. This can be done by using materials that are less dense than the fluid, such as foam or inflatable objects. Archimedes' principle states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object, so if the object weighs less than the fluid it displaces, it will float.
Matter is what is in an object...it is what something is made of.Weight is the effect of gravity on an object.The more matter in an object, the greater effect gravity has on that object, making it weigh more than another object with less matter.Don't forget that size does not always show how heavy something is...If you have a small object which is really dense (contains a lot of matter), it may weight more than a larger object with a low density.
Gravity. When you place something on a liquid, and it is less dense than the liquid, gravity pulling down on the liquid forces the object to float.
A black hole.
That is called a "black hole".
A "Singularity" or a "black hole".
Yes. As an example, a black hole is so dense that its gravity is so strong that even light is drawn into it and cannot escape.
A black hole ofcourse
A black hole
black hole
a singularity
A neutron star is an extremely dense object in which atoms have been crushed by gravity, causing electrons and protons to merge into neutrons. A force known as neutron degeneracy pressure prevents it from collapsing further. The neutron star can emit light and other forms of radiation. A black hole is an object that has completely collapsed under the force of gravity, with all mass coming to a single point called a singularity. The gravity is so strong that, within a certain radius nothing, not even light, can escape.
A black hole is an object that has completely collapsed under the force of gravity into an infinitely dense point. Around it gravity greatly distorts space and time so that, within a certain radius, it is impossible to move outward. Nothing, not even light can escape.
The most dense thing known is dark matter but it has not been proven to exist but it is said to be in black hole and the reason a black hole sucks you in is because it is very dense an object with that density has a very strong gravitational pull
No. A black hole is an object (for lack of a better word) with such intense gravity that nothing, not even light can escape within a certain radius. The center of a black hole consists of an infinitely dense point called a singularity.
