By invisible i assume you mean that the object does not emit electromagnetic radiation.
In which case your answer is dark matter.
Or potentially black holes (if you ignore the possibility of Hawking radiation).
The "black hole" itself is not an object and does not exist. It is just the point of rubicon wherein once passed, nothing can escape the singularity's gravitational pull, hence "black" hole; light (Photons) cannot even escape. However, the singularity within the black hole is an object. It's an object of infinite density and extreme mass compressed into a very tiny point.
Light cannot escape from a black hole due to its extremely strong gravitational pull. The gravity of a black hole is so intense that not even light, the fastest thing in the universe, can escape its grasp.
A black hole is a region in space-time with very strong gravitational pull that even light cannot escape from it. The ESCAPE VELOCITY is greater than SPEED OF LIGHT.
The event horizon is the point of no return around a black hole where the escape velocity exceeds the speed of light. Light cannot escape from beyond the event horizon because the gravitational pull is so strong that even light cannot overcome it. This is why the event horizon appears to "trap" light within the black hole.
In our solar system it would be the sun. But there are much more massive objects beyond our solar sytem that would have a higher pull - the more massive an object is the higher its gravitational pull. a black hole has a huge gravitational pull, so strong that light cannot escape.
A black hole
A black hole is an object with such a strong gravitational force that not even light can escape from it, due to its extremely dense and compact nature.
No, light cannot escape from a black hole due to its strong gravitational pull.
No, neutrinos cannot escape from a black hole due to its strong gravitational pull.
No, the speed of light cannot escape a black hole because the gravitational pull of a black hole is so strong that even light cannot escape it.
Objects cannot escape from a black hole because the gravitational pull is so strong that not even light can escape.
An object with gravity so strong that nothing can escape is called a black hole. These regions of spacetime have such intense gravitational force that they trap even light, which is why they appear "black" or invisible to outside observers.
A black hole is an object that absorbs the most visible light because its gravitational pull is so strong that even light cannot escape from it. This creates a region of complete darkness where no light can be emitted or reflected.
A black hole is an object with such strong gravity that not even light can escape its pull. This intense gravity is due to its extreme density, formed when a massive star collapses in on itself.
Blackholes can affect objects near them strongly. The closer an object gets to the event horizon of a black hole, the more its orbit will be affected. Once an object is pulled in past the event horizon, it cannot escape and is sucked into the black hole. The pull of the singularity is so strong that even light can't escape.
black holes are believed to have the strongest gravitational pull. that and beaches at spring break.
