The unsolved question of Science and still have not answers

It's not a complete list in this post. There are hundreds and thousands of unanswered question or have scientifically no prove available. I will discuss some few questions in this post .

So Here we  start discussion:

 we are alone in universe or not?

May be we Are not alone in universe.Astronomers have working out hard to find answers by hunting placein the universe where there are traces of water. Astronomers have looked at Europa, Mars and planets placed many light years away in a hope that they may find an instance where water might have given rise to life. The next few decades are anticipated to be an exciting time to be an alien hunter with up to 60 billion planets in our Milky Way alone.

What is consciousness?

Science has no clear answer for this. Scientists do not know whether it has to do with the different regions in the brain networked to gather or a single part of the brain. Science communities think that if they can figure this out it will help them understand how consciousness emerges. However the hardest question is why anything should be conscious. A good suggestion is that by integration and processing of information and reacting to the information provided by the sensory inputs our consciousness helps us to distinguishes between what’s real and what’s not and based on this processed information we are given the ability to adapt an survive.

      
   Why do we dream?

We spend one-third of your life dreaming or say while sleeping. Though we spend so much time sleeping, our scientist community hardly knows anything substantially about it. They are still looking out for explanation for why do we sleep and dream. Advance studies in brain imaging conducted over animals suggest more complex understanding such as dreaming plays an important role in memory, learning and emotions.

   Whats so weird about prime numbers?

These are the digits that can only be divided by themselves or one. It is this fact of prime numbers that makes it useful in securing internet and thereby helps you transact online securely. They are the heart beat of internet e-commerce. The prime numbers are used to construct keys capable of locking you’re sensitive information from hackers. Besides their importance in securing our lives online they still remain an enigma. Their tantalizing patterns have attracted brightest minds in mathematics for over centuries now and no one has been successful in taming its weirdness. Yet if someone get to tame it, it’s just going to break the internet
Primes are of the utmost importance to number theorists because they are the building blocks of whole numbers, and important to the world because their odd mathematical properties make them perfect for our current uses.When researching prime numbers, mathematicians are always being both prosaic and practical.

So these are some weird  and unsolved questions. There so many questions to discuss i have discuss some of them.
