SCIENCE DISCOVERY

5 MOST CRUEL EXPERIMENTS DONE ON HUMAN BEINGS.  Have you ever imagined what type of unethical experiment had been conducted on human body? The tim es in history when science was deadly and dangerous.There are many cruel experiments which are performed on human beings.If you just listen these experiments I bet your mind's gonna blow. 1.Josef Mengele (The Angel Of Death) Josef Mengele was born on March 16, 1911, Günzburg, Germany and died on February 7, 1979, Enseada da Bertioga, near  São Paulo , Braz il.At the time of world war 2 he was  Nazi doctor at Auschwitz extermination camp (1943–45).He was known as angel of death because of his bizarre experiments on humans which is listed below . EXPERIMENTS:  He used to stitch blood vessels,organs,skin of the twins to form a Siamese twins (conjoined twins those twins who share pain,diseases and may die at same time)which causes the disease like gangrene which is very dangerous disease. i

Russian researchers in the late 1940s kept five people awake for fifteen days using an experimental gas based stimulant. They were kept in a sealed environment to carefully monitor their oxygen intake so the gas didn't kill them, since it was toxic in high concentrations. This was before closed circuit cameras so they had only microphones and five inch thick glass porthole sized windows into the chamber to monitor them. The chamber was stocked with books, cots to sleep on but no bedding, running water and toilet, and enough dried food to last all five for over a month. The test subjects were political prisoners deemed enemies of the state during World War II. Everything was fine for the first five days; the subjects hardly complained having been promised (falsely) that they would be freed if they submitted to the test and did not sleep for 30 days. Their conversations and activities were monitored and it was noted that they continued to talk about increasingly traumatic inci

      So is time travel possible? General Relativity                                   TO KNOW ABOUT TIME TRAVEL .FIRST YOU NEED TO HAVE SOME KNOWLEDGE ABOUT  GENERAL RELATIVITY.  According to general relativity, mass curves spacetime  mass there is somewhere, the more spacetime will be curved there. Now, what is spacetime, and what does it mean for it to be curved? Well, according to general relativity, space and time are fundamentally connected to each other, and they may together be thought of as forming a unified object called “spacetime.” They’re like the two sides of a coin — they’re fundamentally different from each other, but it’s impossible to think of them separately. In a world where this is no gravity, we say that spacetime is not curved; it is flat. This is the world of special relativity. There’s a precise mathematical meaning, of course, to this whole business of spacetime being curved — it’s related to what I discussed in Lecture Notes 2 with the
