Is there alien life in universe?|Technospace

 The search of alien life started after the UFO crash in Roswell in USA. American Government has started the research in alien life after this crash. But before this Russian government has already started doing research. Many secret bases were made like Area51, Kapustin Yar, etc and many more to continue research and keep it secret from normal people.

But, the question is that is their really any life in this universe rather than us ?

Yes! Our space was started after the Big bang and after that trillions of chemical reactions started in space. We cannot say that there is no life other than ours. There is life. The prove is that in distant celestial bodies, stars, galaxies, universe and multipverse trillions of super bio-chemical reaction is going on which are beyond our imagination and different kinds of weird life is there. 

Thus, there must be alien life. Scientists recently identified- over a million possible- alternatives to DNA, all carbon based. If we ever discover- other carbon based life forms, we will be fundamentally related. They will be our cosmic brother. But would they look anything like us? If they hail from Earth like planets, we could share even more in common, than just our biochemistry. What would life be like- on another planets, if it is evolved? Would it be like, the world today here on Earth? Or would be completely different? There are those, who argue that from the argument of convergent evolution, if conditions on other planets- are similar to here, then we will see- very similar life forms. Animal and plant-like organisms, that look very familiar. On Earth, certain features like eyesight, echo-location and flight have evolved multiple times, independently in different species. This process of convergent evolution could extend to alien planets like Earth, where creatures face similar- environmental pressures. It's no guarantee, but there could be certain- universalities of life, the greatest hits of evolution is on repeat across the universe. Each feature would be a tune- to its local environment. Dimly lit planets would produce huge eyes- to suck in extra light, like nocturnal mammals. Some people have gone- so far as to say that human type organism, humanoids, will occur on other planets. The existence of other- human-like organisms... seems unlikely, given the long convoluted chain of events- that produced us. But we can't rule it out. If just one in every- 100 trillion Earth-like planets produced- a human-like form... There could still be- thousands of creatures- like us out there... But in reality, we are more likely to findsomething lower on the food chain.

Despite our eager imaginations, large complex lifeforms are probably a cosmic rarity. Here on Earth, it took three billion years- for evolution... to produce complex plant and animal life. Simple organisms are hardier, more adaptable... and more widespread. The largest collection- in the museum- of alien life... would likely be... the "Hall of Microbes". Yet finding even- the tiniest alien microbe... would be a profound discovery. And bite-sized life... could leave a big footprint. Like stromatolites on Earth, layers of microbes... could build up into- huge rock mounds over time. Leaving behind eery structures. And in big enough numbers, some alien bacteria... could leave a distinct biosignature, by exhaling gases- that wouldn't coexist naturally... Like oxygen... and methane. There's ways- to make oxygen without life. There's ways- to make- methane without life. But to have them- in the atmosphere together? Is almost impossible... unless you've got biology- making those gases- at the surface. And it would have, a imprint on the planet's- spectrum of colors. Next generation space telescopes- could find a signal like this, on a world not far from home. The closest Sun-like star- with an Earth-like exoplanet, in the habitable zone... is probably only- 20 light years away... and can be seen... with a naked eye. But there may be an even easier target to aim for than tiny Earth-like planets. 

Which type of life can remain forever in this space ?

Mechanised robots are the life which can remain in this universe forever! Like Our lives and alien lives are also sensitive rather super sensitive which cannot remain for ever in this universe. The future robots which will be like the fiction transformers can remain in this universe for ever.
