What If a needle or a grain of sand hits the earth at the speed of light?

Image
We are used to anticipating danger from outer space . A huge almost unknown space hostile to humans and no wonder colossal explosions take place asteroids and comets travel at tremendous speed . There are black holes and all this can potentially cause the death of the earth but what about something small for example an ordinary sewing needle what if one finds itself in space accelerates to the speed of light and then crashes into our planet .   Any object consisting of matter can't move at the speed of light or faster so scientists from NASA are unlikely to ever consider such a disaster well I will do it for them today you'll know how dangerous such small things can be if they are properly accelerated and at the same time, you'll learn about another strange scenario of the end of the world . Our planet is constantly bombarded by various cosmic bodies we don't even notice most of them they just burn up in the atmosphere .     Sometimes celestial b

Would we ever be able to build a Time Machine?

Image
Well, Time Travel is just a  technical problem  now There are several ways we can travel in time (future), two of them are, 1. Orbiting a Black Hole -  Time slows down as we reach an object with high gravitational potential. So, we could orbit closer to a Black Hole, then for us time will run slower compared to the people on Earth. 2. High Velocity -  As per relativity, the faster we move slower the time gets. So, if we could build a spaceship that can reach speed closer to light, then we would be able to travel in time. As I said, right now time travel is a technical problem & our today's technology isn't advanced enough to build such spacecraft. However, some people are trying make this happen, for example,  Harold White  at NASA is trying to build an  Alcubierre Warp Drive .

Does Aliens exist in our Galaxy...How can we connect with them ?

Image
Believe,  Yes, they do!  Here's why, As per the latest estimation, our Milky Way Galaxy contains between 200-400 Billion stars & there exist at least 100 billion potentially habitable Alien planets.

What is the estimated time our Earth will collapse ?

Image
In about 7.5 billion years our Sun will enter the  red giant phase  and expanded beyond Earth's current orbit. It will expand & consume the entire Earth. That's the most probable fate of Earth we know...

Some strange Facts about Nicola Tesla

Image
Here are some strange facts about  Nikola Tesla  : Nikola Tesla was born during a thunderstorm His parents & relatives thought that he will be a child of darkness but instead, he became a child of light. In an interview in 1926, Nikola Tesla discussed the idea of smartphones & live telecast system, which we all use today. Perls drove him crazy. No one knows why he couldn't stand the sight of pearls. When his secretary wore pearl jewelry, he sent her home for the day. Nikola Tesla had a photographic memory. He was able to memorize entire books, pages, pictures, just after going through them once. Tesla also had a powerful imagination & an ability to visualize in three dimensions, which he used to control the terrifying vivid nightmares he suffered from as a child.

How can space expand faster than the speed of light ?

Image
Albert Einstein published Theory of Special Relativity in 1905, about 10 years later he published General Theory of Relativity on 25 November 1915. Through relativity, Einstein made it very clear that nothing can travel faster than the speed of light. But according to the Big Bang Theory space expanded much faster than this speed when it was formed 13.8 Billion ago. Now you would be wondering when nothing can travel faster than the speed of light, then how come our space expansion took place so fast? The answer to this question is that  nothing can move faster than the speed of light  in  our universe , which means those laws & rules are bounded within the Universe. But the universe itself isn't in the universe, so space itself can travel faster than light, but nothing inside it can.

Are aliens real ?

Image
I think so aliens are real but there are 6 types of species found on our planet. One of them is animals and us but the other five are not yet known. We don't have that capability to see them. If you ever happen to read QURAN the Holy Book of Muslims, you could find that Allah has made Prophet (SAWW) Superior over all universes and all types of species. This hits a clue to our brains that aliens may be real. Our eye is blocked to see the other 5 types of species found on our own planet. I think so one of them includes ghosts also but who knows. We could only be able to find it after we are dead. - These are all my personal views only.

Some Facts About The Bermuda Triangle

Image
Bermuda Triangle also is known as  * Devil's Triangle * is one of the biggest mystery of science. Thousands of boats, ships & airplanes have been lost in this area & never found again. Here are some amazing facts about the  Bermuda Triangle, The Bermuda Triangle is not small. In fact, it is quite large and covers an area of 440,000 miles of the sea & its effect can be experienced outside of the triangle too. Whenever any plane or ship disappears in the Triangle, its debris cannot be found. The reason behind this is that Gulf Stream runs near the triangle, which quickly gets rid of the debris. At least 1000 lives are lost within the last 100 years. On average, 4 aircraft and 20 yachts go missing every year. People have experienced electronic fog in the Bermuda triangle, which can be a Time Travel Tunnel too. Pilot Bruce Gernon claims he lost 28 minutes after flying through a time-warping cloud tunnel. The plane went missing from radars, only to re-emerge in Miami

What lies behind a Black Hole ?

Image
Black Holes sucks nearly everything that comes in their path, but where does that matter go? Some scientists believe that Black Holes ends up as a White Hole. Once you enter a Black Holes you will come out from the other end in some other universes or far somewhere far away. But it's just a theoretical idea, no scientific proofs.

Why the discoveries of Nikola Tesla kept hidden from us ?

Image
When Nikola Tesla dies all his research papers & personal documents were seized by the FBI & none of them were shown again. It's believed that he was trying to do something big that would change the world forever, even he planned an anti-gravity rocket. But we don't know what happened to the project. After 50 years of his death, one of his seized documents were made public in which he discussed about the  death ray beam.  We will probably never know what he was actually trying to do.

Questions that science couldn't answer yet!! Can you ?

Image
Here's a list of questions that science couldn't answer yet.  credit: TedEd Why do we dream? How did life begin? Are we alone in the universe? What makes us human? What is consciousness? Is the multiverse theory correct? What is dark matter & what are its properties? What is the purpose of human existence? How the Universe will end? How many species exist on earth? What lies beyond the Universe? How gravity works? What existed before the Big Bang? How does a bicycle stay upright? How & Why do we move forwards in time? Why does space have only three dimensions? Can we get energy from nothing? Is the universe really infinite or just very big? How does the brain generate consciousness? Can we replace damaged brain parts with computational devices? What happens when you die? What are the cures for the world's biggest health problems, like cancer and dementia? Can humans reverse or stop aging? Is there a limit to how smart humans can be? Is biology as universal as chemis

What happens at the moment we die ?

Image
No one for sure can tell what happens at the moment we die, but there are several people with near-death  experience  who can tell  What happens at the moment we die? Ian McCormack  is one of those. While diving for lobster one day on the island of Mauritius was stung on the arm by a box jellyfish. He says that, by the time the ambulance arrived, he felt completely paralyzed and after he made it to the hospital, he was clinically dead for a period of 15 - 20 minutes. Here's how he described his experience, “From the darkness, I began to hear men’s voices screaming at me telling me to ‘shut up’—that I ‘deserved to be there’—-that I was ‘in Hell.’ I couldn’t believe it, but as I stood there a radiant beam of light shone through the darkness and immediately began to lift me upward. I found myself being translated up into an incredibly brilliant beam of pure white light—it seemed to be emanating from a circular opening far above me (I felt like a speck of dust being drawn up into a

What made Albert Einstein a Genius?

Image
In short,  Albert Einstein's brain was different from ours ! Without the contributions of Albert Einstein, our world would be a totally different place. Some of his biggest scientific contributions include, The Brownian motion  which helped us understand the liquids better, The photoelectric effect  which gave us the solar panels, The world's most famous equation  E=mc^2 on which the nuclear bombs are based,& the  Theory of relativity , which helped us understand the deepest mysteries of the Universe. So, what made him so smart to do those wonder & change the world forever?  Here's what made Albert Einstein a Genius? When scientists examined  Einstein's brain deeply , they find out that Einstein's exterior brain was missing a particular wrinkle called a  parietal operculum . So, the size of his parietal lobe was increased by 20%. The parietal lobe is the are of the brain responsible for one's mathematical skills & mental images.

What are some honorable quotes of all time?

Image
Here are some of my favorites, Sometimes it is the people no one imagines anything of who do the things no one can imagine  -  The Imitation Game There is no law except the law that there is no law  -  John Archibald Wheeler It is strange that only extraordinary men make the discoveries, which later appear so easy and simple  -  Georg C. Lichtenberg Two things are infinite: the universe and human stupidity; and I'm not sure about the universe  -  Albert Einstein The good thing about science is that it's true whether or not you believe in it  -  Neil deGrasse Tyson You cannot teach a man anything; you can only help him discover it in himself  -  Galileo Imagination is more important than knowledge  -  Albert Einstein If I have seen further it is by standing on the shoulders of giants  -  Isaac Newton Do you know why people like violence? It is because it feels good. Humans find violence deeply satisfying. But remove the satisfaction, and the act bec

Can we convert Lightning into Electricity ?

Image
One lightning strike will produce around $100 worth of electricity, whereas it will cost millions of dollars to build such towers which can regulate such high voltage. If we see the data, there are about 7 lightning strikes per year per square mile. To capture the strikes in one square mile you would need dozens of 250-1000 foot high towers, & all of them having very costly capacitors at their base. So, I think its not a good idea.

Why a human becomes old ?

Image
Ageing is the process of becoming older. Ageing is among the greatest known risk factors for most human diseases of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes. The causes of ageing are uncertain; current theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail, or to the programmed ageing concept, whereby internal processes

How do Ships float in water ?

Image
According to the  Archimedes principle , " an object in a fluid experiences an upward force equal to the weight of the fluid displaced by it. " The same principle goes for the floating ships. The reason ships float is that they displace a lot of water, if a ship could not push enough water out of the way, it would probably sink. The displaced water wants to return in its original form, where the ship is now, & keeps pushing it upwards. As a result, we get a smoothly floating ship. The force which pushes the ship up is called the buoyancy force. Designers keep it in mind that the ship will displace the total amount of water equal to its weight, way before the water gets in.

Why the use of mobile phone is prohibited during the flights ?

Image
The Federal Communications Commission (FCC) banned in-flight use of most cell phones and wireless devices in 1991, citing the reason for ground network interference. They say that the cell phone calls affect the flight crew contact with ground staff. There are complaints from the Cabin crew that these cell phones waves might be responsible for autopilot disconnects, or instrument display malfunctions

Is it really possible to keep our eyes open during a sneeze ?

Image
The nose and eyes are linked by cranial nerves, as a result the stimulation from the sneeze travels up one nerve to the brain, then down another nerve to the eyelids, triggering a blink for most people. It's impossible to keep our eyes open during a sneeze. It's a  built-in reflex .

Why sunsets on Mars are blue ?

Image
Earth has a  thick atmosphere  due to which the phenomenon  Rayleigh scattering  occurs. When the sun is low in the sky (during the sunrise & sunset), the light has to travel a long path through the atmosphere to reach us. As a result, most of the blue photons are scattered away due to less wavelength & only the red photons will reach us. So, the sunset at Earth appears red. But Mars's atmosphere is different from Earth.  Mars  has a very thin, dry, and dusty atmosphere, it's roughly 100 times thinner than Earth. This means it scatters mostly the high wavelength (red) photons uniformly and blue photons scatter only a slight angle. As a result, mostly blue photons reach the surface when the sun goes down & we get a beautiful blue sunset on Mars.

I'm 16 years now & I'm very skinny. How can I gain weight ?

Image
There could be several causes of bringing skinny or underweight. Some of them are genetics problems, metabolism, drug use, physical or mental illness, poor eating habits, fast metabolism system, poor lifestyle, overwork or stress, etc. Here are some home remedies to gain weight, Milk & Banana -  Bananas are full of carbohydrates & potassium that give you instant energy. If you want to gain weight then you should eat a banana daily in the morning with a glass of warm milk. Potatoes -  Potatoes contain significant amounts of fiber which helps. Fiber helps lower the total amount of cholesterol in the blood, & also decreasing the risk of heart disease. Increase Protein Intake -  Protein is the building block, and your body is going to be starving for it if you don't add enough proteins to your diet. Some good sources of protein are Milk, Cheese, Eggs, Beans, Seafood, Pulses, etc. Daily Exercises -  Exercise is essential in building muscles which also aids weight ga

So if we can turn ourself into Photon using some kind of machine , Can we travel at the speed of light ?

Image
Light travels so  fast  because it has  no mass  but still some momentum. The particles that make up EM radiation are called photons where each and every photon has a packet or quantum of energy depending upon its frequency. So, yes. If you could turn yourself into a photon you will reach the speed of light as soon as you do it.

Does God exists ?

Image
Well, religion has played a very important role in the ancient times. It united people in groups that stayed together & further transformed into today's modern world. The base of any religion is  God . We don't know if God is real because there are no scientific pieces of evidence of it. So, if there's a god we have nothing to worry about. We're good to go. But in order to prove something, science requires pieces of evidence that can be tested in a lab. God is a concept that can't be tested, also we have no evidence of it. So, it becomes our duty to make a change in our own existence & explore the unknown.

What makes our behaviour different than others ? Some people are talkative and some dont, some people are short tempered and some dont, some are clever and some dont ?

Image
Human behavior is the responses of individuals or groups of humans to internal and external stimuli. It refers to the array of every physical action and observable emotion associated with individuals, as well as the human race. While specific traits of one's personality and temperament may be more consistent, other behaviors will change as one moves from birth through adulthood. In addition to being dictated by age and genetics, behavior, driven in part by thoughts and feelings, is an insight into the individual psyche, revealing among other things attitudes and values. Social behavior, a subset of human behavior, studies the considerable influence of social interaction and culture. Additional influences include ethics, encircling, authority, rapport, hypnosis, persuasion, and coercion. The behavior of humans (and other organisms or even mechanisms) falls within a range with some behavior being common, some unusual, some acceptable, and some beyond acceptable limits. In sociology,

Machenism of Earth's Magnetic Field

Image
Fusion occurs at the center of our Sun, as a result of which it blasts the energetic particles ( Solar Winds ) like protons & electrons, all the time. Earth's Magnetic field prevents those energetic particles from reaching us. Just like that, w ithout magnetic field Oceans will evaporate, life will die because of radiation, greenery will vanish & finally, Earth will turn into Mars within a million years.
