The development of the world in medical, technological and many more fields is because of science. Science has an answer to almost everything about this world and how it works. Although there are some things science itself cannot answer and understand. Let us see what are those questions which science cannot yet understand.
What is Consciousness in Science?
Being aware of everything around us. Surroundings, objects, People, sounds and other senses. Because of our awareness about everything around us, we tend to think a lot, be more curious, discuss different things.
There are in total 4 states of consciousness:
1) Consciousness when you are awake.
2) Consciousness when you are in the state of dream filled sleep.
3) Consciousness when you are in deep sleep state.
4) Consciousness when you are beyond deep sleep state.
From the 4 different types of consciousness, we human have, it is pretty clear that consciousness stems from our mind. But scientist are pretty confused about what actually is consciousness, what is its origin, why do we have it or need it. Scientists are also unsure that is consciousness part on only the human brain or is it present in different living beings too and not just us.
Scientists have determined that other animals such as dogs, cats and other mammals definitely have consciousness. Although that consciousness is at a much lower level compared to what us human beings have. We are the most aware beings of the animal kingdom.
Scientists on the topic of the origins of consciousness speculate that it might have been the work of evolution. Our awareness level must have increased as we evolved into what we are today. We have this consciousness for thinking complicated things and forming complicated questions. But all of this is just a theory. We hardly know anything about either consciousness or our brain. Our brain is the most complex organ and we do not even fully understand it yet.
How do our brains function?
The brain is the most important organ in humans and any other multi cellular living being. Without brain we would not be able to function properly, have critical thinking skills. Well, without a brain we would not be alive at all in the first place.
Brain is not a simple organ. The functioning of brain is extremely complex and scientists themselves do not properly understand it. We can do our functions, thinking, because we have a brain. Our voluntary and involuntary organs inside our body can function because we have a brain. We have senses all thanks to the brain. But a brain simply does not work out all this magically. It has millions of little synapses inside it and through those synapses electricity passes. Because of that electricity our brain can function.
But scientists are not sure where that said electricity comes from. From which part of our brain or body does that electricity come from that helps in the functioning of brain. How are we able to think and dream because of our brain and the electrical signals coming from the synapses?
Brain is so complex that scientists have a hard time truly understanding parts of it.
Why do we dream in Science?
During your latest shut-eye adventures, you chopped the head off of a six-legged rabbit while wearing a neon pink bonnet. And screaming, “Gesundheit” at the top of your lungs. You aren’t sure whether that dream means something. Unless it’s that perhaps you consumed too many hallucinogens during college, or merely ate some bad carrots yesterday.
Scientists and sleep experts know when people normally dream. Typically, you dream during the rapid-eye movement(REM) portion of the sleep cycle. You can see when a person (or even your cat or dog) is experiencing REM sleep because their eyes zip to and fro and their bodies may twitch and jerk, too. The brain’s electrical patterns are very active in this phase, just like when you’re awake.
But researchers don’t really know WHY you dream. It may be a way of reflecting on or releasing the stress of everyday life, or even an unconscious way of helping you unravel challenging experiences. It could be a way that your mind protects itself from threatens and dangers.
It could be a biochemical way for your brain to sort, file or store short- or long-term information. Perhaps dreams are a way to reconcile your past and present experiences to prepare and steel you for the future.
Regardless of their purpose, dreams are a cornerstone of the human experience. They entertain and haunt us and serve as reminders that our inner world is just as deep and strange as the exterior world all around us.
What came before the big bang in Science?
There are no possible answer as to what came before the big bang, before everything began. Even before time itself began. There are number of theories as to what must have been before the big bang. But all of that will probably remain a theory forever because we do not have any means to confirm any of the theories. Although it is for certain that the big bang happen as the universe is expanding.
Is it possible to live forever?
We live in an amazing time: we’re starting to think of “ageing”. Not as a fact of life, but a disease that can be nicely treated and possibly prevented, or at least put off for a very long time. Our knowledge of what causes us to age – and what allows some animals to live longer than others – is expanding rapidly. And though we haven’t quite worked out all the details.
The clues we are gathering about DNA damage, the balance of ageing, metabolism and reproductive fitness. Plus the genes that regulate this, are filling out a bigger picture, potentially leading to drug treatments. But the real question is not how we’re going to live longer but how we are going to live well longer. And since many diseases, such as diabetes and cancer, are diseases of ageing, treating ageing itself could be the key.
What is inside the black hole?
Black holes are one of the most interesting, fascinating and mysterious objects in our universe. Einstein predicted the existence of black holes and he was right about them.
They are the most mysterious and terrifying object present in out universe. Learning what is inside them is almost an impossible task as of today. As black hole sucks in and destroys everything that comes near it with its high gravitational force.
What is the universe made of?
Astronomers face an embarrassing conundrum: they don’t know what 95% of the universe’s made of. Atoms, which form everything we see around us, only account for a measly 5%. Over the past 80 years it has become clear that the substantial remainder’s comprised of two shadowy entities – dark matter and dark energy. The former, first discovered in 1933, acts as an invisible glue, binding galaxies and galaxy clusters together. Unveiled in 1998, the latter is pushing the universe’s expansion to ever greater speeds. Astronomers are closing in on the true identities of these unseen interlopers.
