Answer:
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.[1] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[2][3]
The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, according to general relativity it has no locally detectable features.[4] In many ways, a black hole acts like an ideal black body, as it reflects no light.[5][6] Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe directly.
Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.[7] The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretiThe verse in 1 John 5:20 is very mysterious and very encouraging at the same time, saying, “And we know that the Son of God has come and has given us an understanding that we might know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life“. Here it doesn’t say that we are in Christ or in God, but in the True One, and we can know Him who is True, and, This is the True God! This is a very particular and subjective way of speaking about God – He is the True One!
The True One – God becoming subjective to us
Is God only the Creator to you? Is He only your Savior? If God is merely the objective God, yes, He is your God, but He is not that subjective or related to you. But in 1 John 5:20 we see that God is the True One because we experience Him subjectively. The Creator and the Mighty God has come through incarnation, crucifixion, and resurrection, and He as the Spirit of reality has given to us an understanding to know Him as the True One. He must become true to us subjectively to us in our experience.
To know the True One is to know the divine reality – in Greek, “the true” is alethinos, and “reality” is aletheia, coming from the same root word. The divine reality, which is God Himself, has become our subjective reality. The Son of God has given us an understanding so that we the believers may know – that is, we may experience, enjoy, and possess – the divine reality! How do we know the True One? We know Him by experiencTiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell. Phew! All people fart sometimes, whether they live in France, the Fiji islands, or Fresno, California!In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.

Forces can be described as a push or pull on an object. They can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate.

The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time. If the mass of the object is constant, this law implies that the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.
Concepts related to force include: thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces changes i
