How does a person which stands in a planet near a black hole observe the people in the earth?
Can a body approach at the speed of light as it approaches a black hole? Who studies black holes? Is Earth in a black hole? If a black hole was in front of us could we see the object behind it? Where can I see a real picture of a black hole? How can black holes attract objects outside the event horizon if gravity moves at the speed of light? What is there on the back side of a black hole? What is the event horizon in a black hole? What would happen to a person if he enters a black hole? What do scientists think is inside of a black hole or on the other side? Can gravitons escape the event horizon of a black hole? If not, how can we detect the black hole's gravity? What is an event horizon of a black hole? How can we see black holes if light does not escape? Doesn't this mean that it does not reflect light? How can we see black holes if light does not escape? Doesn't this mean that the hole does not reflect light? How do we observe planets with radio telescopes? Is there a singularity inside the event horizon of a black hole? Is Earth a black hole? Is there a ring current at the event horizon of a black hole? Where do an object in the space go when it falls into a black hole? How do we know we are not living in a black hole? What is a black hole? How can we understand it? What does a black hole look like? Two moving observers cycling around equator in an opposite direction at 0.5C. What will they measure when exchanging light signals in each orbit? How do they measure gravity in other planets and stars? On seeing the picture of any planet what will be your key observations? Would it be possible to orbit a black hole inside the event horizon? Could a black hole have planets orbiting it? Are there any solar systems that the planet orbit around black hole like the film Interstellar? Could there actually be something on the other side of a black hole? How do stationary observers and observers travelling near light speeds view one another if they made observations through remote monitoring devices?
