10. What is the universe made of?
What is the universe made of?
It is an embarrassing fact that our scientists do not know what 95% of our universe is made up of. Everything that we see around us is made up of Atoms and barely accounts for 5% of the universe. In last 80 years the scientists have barely able to conclude that the remainder comprises of some dark matter and dark energy. The former was discovered in 1933 and it acts as invisible glue that binds and holds the galaxies and galaxies cluster together. The later was found in 1998 and it was observed that it is accelerating the universe expansion with tremendous speed.
9. How did life begin?
How did life begin?
No one has an answer for it. Biology says billions of years ago some simple chemicals got together and made the first molecule self-sufficient to replicate itself. We humans are somehow linked by evolution to those early biological molecules. But the question still remains at large that how did those basic chemicals present on the early Earth. More so ever what prompted them to spontaneously arrange themselves to resemble life? Stanley Miller a chemist proposed his theory of soup; this still isn’t enough to get us convinced about what happened. There are many theories out there but practically no answers.
8. Are we alone in the universe?
Are we alone in the universe?
May be not! Astronomers have been working out hard to find the answers by hunting places in 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.
7. What is consciousness?
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.
6. Why do we dream?
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.
5. Are there other universes?
Are there other universes?
Upfront answer would be: it is very unlikely. Since by changing some of the setting only slightly the life on Earth could become impossible. Given a fact there are 60 billion planets out there and each would be existing in its own unique setting, may be somewhere some planet exist with setting just optimum for life to sustain. The idea sound crazy, but cosmology and quantum physics have the evidence that points in that direction.
4. Where do we put all the carbon?
Where do we put all the carbon?
Yes, it’s at the 4th position of top unanswered science questions. Far past many hundreds of years we have been filling the atmosphere with carbon dioxide by burning the fossil fuels that so far had locked the away below the earth surface. Now we got to put all the carbon back or else we risk the consequences of a warming climate. But no one knows how to do it.
3. What’s so weird about prime numbers?
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.
look at these............ awww there is a chick too............... are these from some beauty contest of evolution?
