You are crossing the event horizon of a black hole
When you are feeling like spaghetti and you are normally only about 2 meters tall, you are now about 25 meters long, then look up over your head, you see things moving pretty quickly in the universe but that lasts only a brief instant, and then all contact with the universe is lost, you are crossing the event horizon of a black hole.
<h3>What happens when you are crossing the event horizon of a black hole?</h3>
- The point of no return is the black hole's event horizon.
- Anything that continues beyond this point will be absorbed by the black hole and disappear from the known universe forever.
- The black hole's gravity is so strong at the event horizon that it cannot be overcome or resisted by any mechanical force.
<h3>Is it possible to endure inside an event horizon?</h3>
- As a result, the individual would survive and gently float over the event horizon of the black hole without being harmed or stretched into a long, thin noodle.
<h3>What occurs beyond the horizon of the event?</h3>
- A singularity is a truly tiny point that lies beyond the event horizon where gravity is so strong that space-time itself is infinitely bent.
- The principles of physics as they exist presently break down at this point, making any hypotheses about what lies beyond mere conjecture.

Answer: 1.65m
Explanation:
Refractive index in terms of the depth of liquid is the ratio of the real depth to the apparent depth of the liquid i.e Refractive index =Real depth/apparent depth
Refractive index of water given = 1.33
Real depth is the measure of how deep is the liquid while apparent depth is the depth at the surface of the liquid.
Real depth = 2.2m
Apparent depth =?
Applying the formula above
Apparent depth =Real depth/refractive index
= 2.2/1.33
= 1.65m
Therefore, the circle of light that exits the surface of the water when that light shines in the middle of the night is 1.65m wide
The object is fixed relative to the motion you are trying to describe.
