Where are you getting this from?Invutil said:The effect of a gravity source on space curvature is proportional to sqrt(d) where d is the distance
There's no such thing as internal space, and the sign of the spatial coordinate is arbitrary: I can always "re-zero" my ruler so that all distances are positive.so if d is negative (internal) space
What do complex numbers have to do with extra dimensions?does it become a complex number and get another dimension?
A black hole is a region in space where gravity is so strong that nothing, including light, can escape its pull. This happens when a massive star dies and its core collapses under its own gravity.
Inside a black hole is a singularity, which is a point of infinite density and zero volume. According to our current understanding of physics, all matter and energy that enters a black hole gets compressed into this singularity.
No, nothing can escape from a black hole once it crosses the event horizon, which is the point of no return. This includes light, making black holes invisible to the naked eye.
Black holes cannot be directly observed, but their presence can be detected through the effects of their strong gravitational pull on nearby matter. This can be seen through the distortion of light and the motion of nearby objects.
Yes, black holes can move through space just like any other object, but their movement is determined by the laws of gravity. They can also merge with other black holes, resulting in even larger black holes.
