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.
2. What’s at the bottom of the ocean?
Whats at the bottom of the ocean?95
percent of our oceans remain un-explored. No one knows what lies there.
Don Walsh and Jacques Piccard went seven miles down in the year 1960,
the deepest part of the ocean to find the answer. Their voyage turned
out to be just the beginning of the human endeavor and provided them the
glimpse of the life at the sea floor. It is very difficult to reach the
bottom of the ocean and hence most of the time the explorers have to
resort to sending unmanned vehicles with cameras.
1. What’s at the bottom of a black hole?
Whats at the bottom of a black hole?At
the 1st of all top unanswered science questions we have the something
related Black Hole. Our science has yet not evolved enough to provide
the tool to find the answer for this question. Einstein’s theory on
general relativity says that when black hole is created by a dying and
collapsing star, it continues to shrink into itself, till it forms an
infinite small, infinite dense point referred to as singularity. But
that’s just the glimpse of the larger picture and its now only in the
hands of the time to tell us exactly what lies at the bottom of the
black hole.
