Answers
1.)As of 2017, microfossils (fossilised microorganisms) within hydrothermal-vent precipitates dated 3.77 to 4.28 Gya in rocks in Quebec may harbour the oldest record of life on Earth, suggesting life started soon after ocean formation 4.4 Gya during the Hadean Eon.
2.) Dreams are hallucinations that occur during certain stages of sleep. They're strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health.
3.) A clear rule determines exactly what makes a prime: it's a whole number that can't be exactly divided by anything except 1 and itself. But there's no discernable pattern in the occurrence of the primes. ... That's because after the number 5, there are only four possibilities — 1, 3, 7 and 9 — for prime last digits.
4.) There are no cures for any kinds of cancer, but there are treatments that may cure you. Many people are treated for cancer, live out the rest of their life, and die of other causes. Many others are treated for cancer and still die from it, although treatment may give them more time: even years or decades.
5.) Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Time travel is a widely recognized concept in philosophy and fiction.
6.) Our universe may be one of many, physicists say. The universe we live in may not be the only one out there. In fact, our universe could be just one of an infinite number of universes making up a "multiverse." ... In fact, some experts think the existence of hidden universes is more likely than not.
7.) Consciousness at its simplest is "sentience or awareness of internal or external existence". Despite centuries of analyses, definitions, explanations and debates by philosophers and scientists, consciousness remains puzzling and controversial, being "at once the most familiar and most mysterious aspect of our lives".
8.) Researchers at the Large Hadron Collider Beauty (LHCb) experiment at CERN near Geneva have discovered antimatter and matter versions of “charm” quarks—one of six types, or flavors, of a class of elementary matter particles—acting differently from one another.
Answer:
(1) Life began in Earth, has arisen from simple abiotic simple organic matters by the presence of life supporting elements such as water, food , and oxygen was available abundantly. Then it slowly evolved to eukaryotic cells, then prokaryotic, then after millions of years, it made up to the present level of complex multicellular organisms.
(2) When we sleep, we have less consciousness to the outside surroundings. And when there is less outward consciousness, it is diverted to body parts. And thus it is believed that, brain works nore efficiently when we sleep!. It is believed, when there is stimulus from any part of the body, the mind portraits an impression, may be an sequence of discontinuous images in the brain to form dreams we see. Some may relate to our present life experiences. Some believe, brain tries to surf the brain itself to recollect the deep forgotten memories. There is still research going on to exactly define what is dream.
Sigmund Freud has said his hypothesis in the book " The Interpretation of Dreams".
(3) There could be no pattern in prime numbers. When the number has only 2 factors, i.e, 1 and the number itself, then it is called prime number other than 1. Prime numbers are scattered in real number set.
(4) Cancer can be treated by chemotherapy, a drug treatment that uses powerful chemicals to kill fast-growing cells in your body, i.e, cancerous cells.
(5) We are time travelling every second. Understanding Time Travel is a bit confusing, but still, interesting. If one want to understand time and space one should know about Einstein's theory of relativity. According to him time is not constant in universe, it is relative to speed. We know that nothing is go faster than light. When your speed equals to the speed of light, time will stop. If you are approaching speed of light your in future.(>c past ) This seems crazy but it's true.
We will not go to past or future. One reason maybe stated as grandfather paradox. Imagine you went to past and murdered your grandfather, then you would not be born in the timeline.
Every day we are all experiencing time travel. "Looking at the stars means looking at the past." For ex: We know that the light from sun will take 8 minuts to reach Earth. That means when ever you are seeing the sun, you actually seeing it as it was 8 min ago. So we can say that sun is 8 light minutes away from us(Earth).
So now you are a time traveller. The speed of light enable us the ability to look back into time". This is the most amazing thing in 3D universe. In this way our scientists know that the universe was created 13.8 billion years ago. Because by using our most powerfull teliscopes in any direction we can only cover 13.8 billion light years away galaxies. We can't see beyond that. The reason must be either universe end there or farther galaxies moving away faster than light speed. So the light from the farther galaxies will never reach us. Here the same speed of light is a barrier to us. Hope you would understand.
(6) Many scientists are proposing multi-universe theory, billions of universe, each with different physical laws.
For ex: Gravity is attractive in our universe and maybe, just intuition, maybe repulsive in another universe. Maybe there will be another Hari in another universe typing these for somebody else!
(7) Consciousness is just the state of being aware and responsive to surrounding stimuli. Maybe, Consciousness can be the key for life. The Upanishad discuss the "four states of consciousness" as awake, dream-filled sleep, deep sleep, and beyond deep sleep. These are just too complex for human mind to define, yet possible.
(8) Antimatter is, till date, not yet exactly located. But Mathematics has proofs for it's existence. There have being instances where sudden energy bursts were recorded way beyond our galaxies, which, our scientists believe may be the sign of antimatter coming in contact with normal matter. When they interact with each other, they annihilate themselves to produce huge amount of energy in the form of ultraviolet rays. Some may exhibits visible rays as well.
