Were there any civilization on Earth before us

 Civilization before us Our human life evolved from the jungles of Africa about seventy thousand years ago. At that time, we lived in caves, ate wild groundnuts, hunted with ordinary spears and stones, and sometimes we hunted ourselves. But the descendants of the same ancestor who ran through the jungles of Africa yesterday are now parading in space. would ancient civilization look like this? Today our food and lifestyle have changed. Today, the same people who live in caves and hang in the trees are flying in skyscrapers and sophisticated means. Today we have reached the zenith of development. Today, we have developed so much that we are imagining building a house on the moon, the satellite of the earth. In addition, we are leading the plan to establish human settlements by exploring and researching other planets in the solar system. Not only that, today we have discovered such secrets of the universe. When there was no knowledge about it, our ancestors would sometimes look at the

Is it possible to go to a world outside the solar system?


Is it possible to go to a world outside the solar system?

When an astronaut thinks about observing the universe, he remembers the Theory of Relativity. The great scientist Albert Einstein said that nothing could be dropped or sent in space at or above the speed of light, but today some researchers are working to build a spacecraft that can fly at the speed of light or even beyond the laws of physics.

1. Project Daedalus

"Project Daedalus" has recently been developed in the concept of a spacecraft called "Project Daedalus" to explore beyond our universe. It was created in the 1970s by scientists from the British Interplatonary Society. According to astronomers, there is a Bernard star about 6 light-years from Earth. Among the stars closest to our Sun, the Alpha Centauri 9 is the second most active star and the Proxima Centauri is the ninth most obscure. The star was discovered in 1916 by American astronomer Edward Emerson Bernard Bhamdhabcham. That is why it is named Bernard. It is a very low-mass red dwarf and is believed to have a possible planet in the solar system. With this in mind, Project Daedalus has been designed. According to astronomers, the star also has a gaseous planet in its solar system, which is constantly orbiting it. Scientists have recently discovered a planet in this star system.

Scientists designed Project Daedalus after five years of hard work. Two nuclear rockets of 54,000 tons will be connected to its interior in two phases. Which will provide the vehicle with 500 tons of robotic proof, 12% of the speed of light.
Its speed is so high that the Daedalus Bernard will reach the star system in 50 years. The rocket attached to the vehicle is powered by nuclear fusion and the electron beam is used to extract its fuel. Then the extracted fuel is like helium three. Which can be extracted from the surface of the moon. Even though it is a rocket weighing many tons, this vehicle will be able to reach its full speed in just 4 years. Even if the Daedalus runs out of fuel, it will not slow down.
Due to the large size of the Daedalus spacecraft, it will be impossible to lift it above the Earth's surface. So this spacecraft will have to be built in Earth orbit, but so far we do not have the capacity to build any spacecraft. According to Crawford, a scientist at Burkeback College in the UK, a spacecraft like the Daedalus will be ready in space in the next 100 years.

2. Project Icarus

This project is based on Project Daedalus, designed in The 1970s. It is a joint venture between the Icarus British Interplatanary Society and the Icarus Interstellar Organization. According to a scientist working on the project, a spacecraft like the Icarus could be built by 2,100. With the help of this project, we will be able to go to any planet 22 light-years away from the Earth, that is, to a planet with the possibility of life like Earth orbiting the star Proxima Centauri.

To make this project a reality, it was proposed to install a fusion rocket engine in the Icarus spacecraft. The concept was developed to use a different type of nuclear fuel and that fuel would also be detonated by a laser instead of an electron beam. Its prop will be less than the 400-ton robotic Prob of the Daedalus, so the vehicle will be able to get its speed at less fuel than the Daedalus.


3. Bussard Ramjet

Bussard Ramjet is a 1960 proposal by physicist Robert Bujad. This connects the high power of the fusion rocket to the low fuel requirement of the light cell. Instead of its own fuel, Bujad Ramjet will pull particles and gas from the interstellar space into an electromagnetic field shaped like its own funnel. The hydrogen obtained through interstellar space will be used as fuel in a fusion rocket attached to the rear of the spacecraft. Which will propel this vehicle forward at high speed?

According to one theory, the Bujad Ramjet will continue to operate as long as there are gases and particles in space and the speed of this spacecraft will be very close to the speed of light, but unfortunately! Such particles are very rare in the stars around our solar system and there is also very little hydrogen so it will not be enough to move the spacecraft forward.

4. LightSail

According to scientist Crawford, humans do not need to use any rockets to enter interstellar space. The light cell, which uses the light's pressure to propel the spacecraft's payload, is considered to be the largest tool for checking interstellar space. A 46-foot-wide light cell was used in a Japanese spacecraft in 2010 to complete a six-month voyage to Venice Planet.
The light cell was considered to be the best tool for examining the solar system because it is powered by sunlight, but the speed of the light cell is not enough to cross the interstellar distance in the allotted time. According to scientist Croft, this problem can be solved by pushing this light cell with high speed at the beginning with a powerful laser. This will make the speed of the light cell very high from the beginning because it will be built in the orbit of the earth. This vehicle will not have to carry fuel so it will weigh a lot less.

The idea to run a light cell vehicle from a laser came from the Breakthrough StarSt project. Announced by Yuri Milner and Stephen Hawking. A laser-powered light cell vehicle will be built for the project by 2036 at a cost of резреж 10 billion. About one thousand stamp size vehicles will be made in this project. It will weigh only a few grams and will be attached to a 13-foot light cell. Which will be projected from Mother Ship deployed in Earth orbit. They will be launched out of Earth orbit at about 15-20 percent of the speed of light in space with the help of a laser, and it will take about 20 to 30 years to reach the Proxima Centauri and the Alpha Centauri system, which is 4 light-years away. But the biggest challenge for scientists is to build a laser that can run a light cell spacecraft.

5. Antimatter Rocket and Black Hole Drive

Apart from the various projects mentioned above, other options for interstellar travel have also been put forward. According to scientist Croft, antimatter can be a very good fuel if the rocket is powered by a highly destructive reaction of quasi-matter and antimatter. Because it has a lot of energy density but it is not in our environment and even if it has to be made it will be very difficult, more costly, and extremely dangerous. A unique technology will be used to fly such a spacecraft. In which the engine of the vehicle will have a Schwarzschild Kugelblitz drive. In which an artificial black hole will be used for energy.

This SK drive will convert the energy of the small black hole into energy by controlling the intense and extremely dangerous radiation. Which can be used to propel the spacecraft forward. Here an artificial black hole will only work for a short time and then a new black hole will have to be created. According to a 2009 newspaper, the SK drive will reach 10 percent of the speed of light in about 20 days. A black hole will produce energy for 3.5 years and give 160 petawatts of energy to the vehicle in this time period.

6. Sleeper ships

Slipper sips are a slow boat, where people are kept in deep space, meaning they will be kept in a special kind of hibernation because no matter how long the journey, their age will not be affected.


 

8. Embryo ships

Embryo sips will be a spacecraft that will have unconscious and frozen passengers, not living and sleeping people, and they will come to a conscious state as soon as they reach another planet, and they will be given all the information by the robots in the spacecraft.

The man who jumped from space, Felix Baumgardner

The man who jumped from space; Felix Baum Gardner Most people in this world want to hear your praise. No matter how much risk they have to take for this, they want to present their work to the world. Till today no one else has been able to do such work. They want to do such work. Even if life itself is not in danger. Some are taking selfies in buildings thousands of feet high, while others are diving into the ocean thousands of meters deep. And some are riding bicycles on steep slopes, while others are riding hundreds of tons on their own bodies. Some stuntmen even go to great lengths to set a new record. A similar act was made public on October 14, 2012. He had this new artificial and he was - Felix Baumgartner. How did this happen, and who is the world's most adventurous and skilled skydiver, Felix Baum? We will discuss this topic in today's special series. Felix Baumgardner is a skydiver by profession.

A mysterious flight 914, explanation with full details

A mysterious ship A charter plane carrying 57 passengers flight 914 from an international airport in New York City. This plane flying towards Miami will disappear halfway. After thousands of searches, there was no sign of the plane crash. Eventually, after months of searching, nothing was found, but it was officially declared an accident. But surprisingly, the same plane landed 37 years after takeoff. When the plane disappeared on July 2, 1955, no trace of it was found during years of searching. But in 1992, 37 years after the plane suddenly disappeared, the air traffic controller at Caracas Airport in Venezuela was contacted by the ATC to land on an unknown plane. When the traffic controller asked for an introduction to the pilot of the plane, he replied that it was DC Four Flight 914. Where we are flown from New York to Miami Florida with 57 passengers and crew members. When the traffic controller understood the pilot's identity and condition, he almost lost conscio

How to resurrecting dead people? scientist may have found solutions

resurrecting dead people Did you know that some scientists are resurrecting dead people? And by the beginning of the year 2100, human life will reach 140 years. But by then, the earth's population will have halved. We must have seen in some folklore or fictional films that a person is resurrected after death. And sometimes we wonder how pleaser it would be if people who were really dead were really resurrected. Now your imagination may come true. Today, American scientists are working to resurrect the dead. According to scientists, there is a theory that can help revive the dead. In fact, scientists first experimented with resurrecting corpses in the 1960s. The discussion on this issue has started again. After all, is it possible for a person to be resurrected after death? People's curiosity about this is growing. There was a demo video created in 1960 with the help of a machine at the Cryonic Science Society in Arizona, USA. This showed the proc
