    hey my friend Riaz is here. And you are watching your own channel 'Fact & Fiction Bangla'. So how excited are you about making new ones? How do you approach someone you don't even know as a friend? As a civilization we humans are always excited to make friends with other extraterrestrial civilizations. For example, you must have heard about Voyager-1's golden record. Another such attempt was the Arecibo message of 1974. It is a special radio message, much like a secret code. Which only an intelligent creature can decode and understand what it says. This radio signal was sent to a galaxy 25 thousand light years away. But what did we say about our friends in the distant sky, our own? Let's find out.

    Hey, my friend. Riaz here. And you are watching your own channel 'Fact & Fiction Bangla'. You must know that about 65 million years ago an asteroid named 'chicxulub'. It hit the Earth, wiping out the entire dinosaur species. Our ancestors (mammals) survived then because they lived underground. But now the scenario has completely changed, we now live on the surface of the earth. Now if such an asteroid hits the earth then you must understand what will happen. Scientists believe that on 23 April 2029, an asteroid, named 'Apophis', will pass by the Earth. And the chances are that it could hit some part of the Earth. So what can we do here? If the question was asked before 23 September 2022, I would say we have nothing to do but wait and see. Since September 23rd, we have had the technology to alter the trajectory of an incoming asteroid. NASA successfully completed their 'DART' mission on 23 September. So they were able to change the trajectory of an asteroid as per their plan . This technology will save the world from many dangers in the future. However, as you can understand, it was not easy to do. Because nothing like this has ever been done before in human history. Behind this is a lot of careful calculations and the work of hundreds of scientists. Let's see how the trajectory of an asteroid is changed.

    Man's feet landed on the moon, courtesyof NASA's Apollo missions. But about53 years later, how important isit in our lives today? I bet the impact ofthe Apollo missions on our livesis hundreds of times bigger than youthink. Many new revolutionaryscientific technological advances weremade to make the Apollo missions a success.There are so many technologies thatwe can't imagine our daily lifewithout. They were invented only forthe Apollo missions. By the end of thevideo, you will understand theimpact of the Apollo mission on ourlives today.

  • What if We Use 100% of our Brain ♦ যদি আমরা আমাদের সর্বোচ্চ মস্তিস্ক ব্যবহার করি

    What if We Use 100% of our Brain ♦ যদি আমরা আমাদের সর্বোচ্চ মস্তিস্ক ব্যবহার করি

    As you must know, we can only use 10% of our brain. But, this is just a misconception. We use almost 100% of our brain. But not together. At some point, one part of our brain is more active. In fact, when it became popular, we didn't know the function of many parts of our brain, so many neurologists declared them silent areas, that is, the part of the brain that does not do anything. Later it was revealed that this is not true, however, many still believe it. As I said earlier, sometimes one part of our brain is more active. For example, our brain's processing and memory capacity increases greatly during sleep. But, what if we could use 100% of our brains all the time without doing any particular thing? That means 100% of our brain will be active at every moment . Let's find out.

    Problem With Deep Space Travel ♦ মহাকাশ যাত্রায় সমস্যা
    2022/09/22
    In 1976, when the Soviet Union launched a mission to their Salyut-Five space station, Soyuz-21, the last dedicated military space station in the Soviet space program. Commander Boris Volinov and Flight Engineer Vitaly Zholobov were launched for a sixty-six day mission. But after fifty-nine days the mission was aborted and the astronauts returned to Earth. This is due to the astronauts experiencing something terrible and a strange chemical smell. The spacecraft was later inspected. Scientists thought there might be a leak in the spacecraft, from which some gas was entering; It can be smelled. But after inspection, there was no leak, not even any smell. This smell is an astronaut's hallucination. They had been hallucinating for a long time in the harsh conditions of the spacecraft.
