A cryptic deathbed theory given by India’s mathematics genius Srinivasa Ramanujan, has now been proven correct and it could also explain the behavior of black holes.
In 1920, when Ramanujan was on his death-bed, he wrote a letter to his mentor, English mathematician G.H.Hardy describing several new mathematical functions never before heard of, along with an intuition about how they worked.
In his letter, he described several new functions that behaved differently from known theta functions, or modular forms, and yet was very similar to them.
He hypothesized that his mock modular forms corresponded to the ordinary modular forms earlier identified by Carl Jacobi, and that both would wind up with similar outputs for roots of 1.
As per recent findings by American researchers, the formula is correct and could explain the behavior of black holes.

As per latest findings, the most probable cause of widespread eye disease Branch retinal vein occlusion (blockage of the blood vessels that channel blood from the retina) has been identified. Scientists have shown that it is highly probable that thickening of the arterial walls is behind the disease which is a type of blood clot in the eye that blocks the vessels that transport blood from the retina. The disease leads to reduced vision and affects more than 14 million people worldwide. The earlier known causes behind the disease were vague and unclear.
What could be possible benefits of the findings?
The findings makes it crucial for doctors to treat patients diagnosed with the disease with medicine to lower blood pressure in order to prevent blood clots from forming in the heart and brain. Branch retinal vein occlusion is often a sign of increased risk of blood clots in other parts of the body. Disease prevention and treatment of these patients should be targeted at hypertension, diabetes and atherosclerosis, while doctors can save patients from unnecessary treatment with anticoagulants.
