Lifeforms or not lifeforms that's the question.

   

Lifeforms or not lifeforms that's the question. 

Phosphine and life signatures are quite different things than an intelligent alien with spacecraft and well-detected cities. That means there can be lifeforms on some ocean planets. But those lifeforms cannot ever communicate with us. The thing is this: The exoplanet K2-18b is the most promising target for life hunters, but that planet is about 124 ly. from Earth. 

That means. We cannot ever be sure if there is some kind of plankton that exists in that planet's oceans. For confirming that thing. We should travel to exoplanet K2-18b. That planet's atmosphere might be hostile to lifeforms. And the only place where those primitive, maybe procaryotic organisms can exist is the ocean. 

So what does that mean? We cannot confirm the possible life forms at least in the distant worlds. There are suspicions about lifeforms also on some moons in our solar system. The fact is that those lifeforms that can exist in Europa, Triton, and Enceladus or hover in gas giants atmosphere might have a very slow metabolism. 

Astronomer Carl Sagan introduced an idea about hovering medusas on Jupiter and Saturn. And probably Neptune and Uranus's atmosphere. The idea of the lifeforms in the icy moon's ocean is based on the idea that the low gravity and low pressure allow the ocean to stay liquid in low temperatures. If there are some organisms their metabolism will be very slow. Those organisms might use even years to travel meters. Those creatures can be the ice crystals that the DNA controls. Those lifeforms can exist at very low temperatures. 

When we think about things like lifeforms in Venus we must remember that Venus is far from Earth. Its atmosphere is carbon dioxide or monoxide. If you jump out from an airplane at Venus you will not fall as on Earth. You will burn when you are too close to Venus's surface where the temperature is about 600C. 

A dense atmosphere slows speed differently than Earth's atmosphere. Venus's atmosphere is flatter than Earth's. Venus's mountains like Maxwell Montes are not very friendly places for lifeforms. The temperature in those mountains is about 380C. 

The bacteria-type lifeforms can hover at the higher level of Venus's atmosphere above its clouds. There the temperature is much lower than on Venus's surface. 

Sometimes there have been plans to make some stations in the Maxwell Montes area. There the pressure and temperature are more comfortable than on Venus's lowlands. But if we find bacteria from Venus's atmosphere there is the possibility that those bacteria traveled from Earth to that planet hiding in the probes that were not properly sterilized. Another thing is that in some cases phosphine can be the remnant of the bacteria that might died when some probe like Venera hit Venus's atmosphere. 

If those probes were not sterilized they could leave the trail of the living bacteria behind them. And if those bacteria died in the space journey their remnants could leave phosphine signs in Venus's atmosphere. But for making good decisions researchers require those organisms. 

And 600C can destroy any bacteria remnants in that planet's atmosphere. It destroys the DNA that there is no evidence of the bacteria especially if they traveled from Earth.  So maybe the only thing that we can find on Venus is phosphine. That phosphine can form in cells that can be gone or turned into ash a long time ago.

The biggest threat to mankind is overpopulation

House at Espoo

Kimmo Huosionmaa

Overpopulation is the biggest threat to mankind. This is very commonly told the fact and the question why overpopulation is so bad problem is that human being needs space. When the population of people rises, they would need more space, and that would cause wars if some nation wants more living space like Nazis did in 1930's. If the population grows very big, there would be internal pressure for beginning the war against some neighbors. If in those conflicts are used weapons of mass destruction the results would be devastating.


But there have been rumors that in some countries like South Africa, the governments have planned to decrease the population by using biological weapons like hepatitis, and other STD for decreasing the population of their own people. In some plans, the mumps-virus would be put in the drinking water, and that would cause the lifetime sterilized for men.


When we are talking about the birth control, we must understand that talking is not enough for handling this problem, what might cause terrible war. In some talkings have mentioned, that there would be taken the DNA from unborn children, and if those genomes would be unwanted, those babies were sterilized just after the birth. Sterilization by using viruses or X-ray machines would be the most humanitarian method of decreasing the population. Then the woman has got enough children, the X-ray machines would destroy ovum,  without any pain.


And the pill-implants would be put every woman after they got their first child. And if that woman will be allowed to make more babies, those must be something special. Also, The overpopulation will cause social problems, and those problems would be both humanitarian and economical. When the space of the people would be ended, the cities would become unsafe, because they will start to live outside the houses, what means streets.

That could cause the increasing the number of criminal behavior. This causes more problems because the cities must hire more police and security officers. But when we are thinking about the solution for the problems of the space of the cities, we must think that all city would be covered by the giant bubble. Those bubbles can make all city areas very comfortable, and they allow the situation, that the people must not live in their own departments.


Sleeping in the future might happen in the plastic tubes, what will give the person only privacy, what is needed. Those tubes were created by Japanese architect, and they can be one good solution for loss of homes. In this scenario, those tubes might be even free for people, and only families with children would have right to use own rooms. This might be the very radical way of life, but we can always talk also about radical solutions. And maybe in the society of tomorrow is very much different than what we will know it is.
