What are common mistakes I should avoid in life?

 There is this classic film called Moondram Pirai (Sadma in Hindi), which has one of the heart-touching climaxes

[1]

.

A head injury causes a woman to regress to childhood as a result of retrograde amnesia. Lost and confused, she is eventually befriended by a school teacher in Ooty.

A beautiful relationship develops between them. He is smitten by her childlike innocence and purity.

Later, she regains her memory, recognizing her past, and completely forgetting the period between her accident and recovery.

As she is leaving for Chennai with her parents, he follows them to the railway station and tries to gain her attention.

But she does not remember him. He repeatedly calls out to her and mimics a dancing monkey that she had developed a liking for but she thinks he is insane and begging for food.

He continues his futile attempts, but the train eventually leaves with her not recognizing him.

He is left alone at the station, heartbroken.

Most of them who watched this movie climax feel ‘Last scene is so emotional. I cried. I wish she recognised him. I wish she came back to him.’

Now

Let’s say, she recognised him. And she got back to him.

Do you know what would happen?

He will come and drop her at the railway station a week or two later.

Simply because that was not the person he was attracted to and had the most beautiful relationship with.

She is a different person now, who no longer has that innocence or childlike nature. She has different thoughts and makes different conversations now. She is just a plain lookalike of the person whom he was in love with and who is no longer alive.

Likewise

People, out of habit, confusion and emotion, beg the other person to stay in a relationship, or not leave the relationship when it turns abusive.

You forget the fact is that the person you are begging is a different person now.

He is not the same person whom you had fallen for or expected to be your partner. Ask yourself, would you begin a new relationship with such a person? If the answer is no, there is no point in holding on to it.

The same thing happens with friends too.

One mistake people make regarding relationships is expecting the other person to be the same or change parallelly with them. This is not always possible.

As we grow, the political beliefs, the people around us, the books we read, the news we consume and the movies we watch will have a deeper influence on us and our thinking. This can make two people who were at the same point once upon a time to drift somewhere apart. You won’t feel like you are interacting with the same person again. That is natural.

There is a famous quote—

People Change. Memories Stay.

Value the memories but learn to keep your present beautiful as well.

Don’t erase your good memories because your friend is a changed person now.

And don’t forcefully continue being in a relationship with a person you can’t bear anymore for the sake of few good memories.

Is it possible to reach Earth from Alpha Centauri within a human's lifetime, considering the distance of 4.3 light years?

 If a crew left Alpha Centauri at Voyager 1's speed, the trip to Earth would take 70,000 years. But by surfing the shockwaves of nuclear bombs, they could arrive in just 45 years.

At 4.3 light-years away, the journey spans roughly 25 trillion miles. Chemical rockets are hopelessly inadequate for interstellar transit, but physics does not forbid crossing that gulf in a human lifetime. It simply requires a complete reimagining of propulsion.

One theoretical method to achieve this is nuclear pulse propulsion, famously studied during the Cold War under Project Orion. Instead of burning liquid fuel, an Orion-style ship would eject thousands of small nuclear explosives behind it, riding the shockwaves of continuous detonations against a massive pusher plate. Calculations suggest this brutal but effective method could propel a massive ship to 10% of the speed of light, making a 45-year transit possible.

An even faster alternative eliminates the need for the spacecraft to carry its own heavy fuel. Concepts like Breakthrough Starshot propose aiming an array of immensely powerful ground-based lasers at an ultra-thin, highly reflective sail. The continuous photon pressure could theoretically accelerate a craft to 20% of the speed of light. At that velocity, a probe or ship from Alpha Centauri would reach Earth in just over 20 years.

If an advanced civilization could build engines capable of pushing a ship to 99% of the speed of light—perhaps utilizing antimatter annihilation—the journey takes on an entirely different character due to special relativity. While an observer on Earth would watch the ship travel for about 4.3 years, time dilation means the crew onboard would experience the entire transit in just a few months. The true barrier is not time, but energy: accelerating even a small shuttle to relativistic speeds would require more energy than the entire modern world consumes in a year.

What was Lord Krishna's greatest life lesson?

 As per my understanding, his life’s greatest lesson was that Dharma is above all and everything. He believed in this and proved this by his conduct all through his life.

In the childhood, he killed the tyrant king Kamsa, who was his uncle, as he was a great adharmi. Before that he killed many rakshasas sent by Kamsa to kill him because they also were all adharmis, just like Kamsa.

After killing Kamsa, he installed Kamsa’s father Ugrasen as the king of Mathura again instead of becoming king himself.

When Jarasandh attacked Mathura to take revenge on him for killing Kamsa, he killed his entire army but spared him so that he could again collect more adharmis and come again to kill him.

When he saw that people of Mathura could not live peacefully due to repeated attacks of Jarasnadh, he decided to leave Mathura and established the new city of Dwarka in between the sea so that none could attack it easily.

When he fled from Mathura in front of Jarasandh, Jarasndh insulted him and called him ‘ranchhod’ but Lord Krishna did not care for his insult as for him the welfare of people was much more important.

He married all 16,100 girls who were kept in captivity by Narkasur so that they can lead a respectful life in the society as nobody else was ready to accept them.

He helped Pandavas whenever they were in distress as they were righteous people.

He went to the Hastinapur royal court as the peace messenger on behalf of Pandvas as a last attempt to avert the war where he was insulted by Duryodhan and also tried to capture him.

He helped preserve the modesty of Draupadi when she was being disrobed in the Hastinapur royal court.

He was strictly against taking of any pledge by any person as the pledge may prove to be harmful in future.

In case of Bhishma, his pledge of leaving the throne of Hastinapur for his step mother Satyavati’s future sons proved to be very harmful for Hastinapur.

Drona also gave more importance to Dhritrashtra’s help and supported him despite knowing that Duryodhan was on the wrong path. Same was the case with Karna who gave more importance to Duryodhan’s friendship than dharma.

He agreed to become the charioteer for his best friend Arjun and guided & mentored him by reciting the divine knowledge of Geeta when Arjun was in a great dilemma about his duty.

He rebuked Arjun on the 3rd and 9th day of war for fighting very mildly with Bhishma and himself picked weapons to kill Bhishma as it was important for victory of dharma.

He helped Arjun reach Jaydrath and told Arjun about the boon of Jaydrath’s father to him and guided and motivated him to kill him before sunset.

He saved Arjun many times during the war, helped Pandavas in eliminating Bhishma, Drona and Karna.

He motivated Yudhishthir to kill Shalya and signaled Bheem to kill Duryodhan by striking his thigh to finally end the war.

What are some of the dark lessons that life showed you?

1. 1% people own the half of the world's wealth.
2. Most men love to think about sexual fantasies.
3. Plenty of people like extra-marital affairs.
4. Men are more likely to cheat than women. But as women become more financially independent, they are beginning to act more like men with respect to infidelity.
5. At the one stage of life, you will be alone, your parents, spouse, children, no one will be with you.
6. Our time is limited in the world. One day we will be no more. Our good memories, mother's love, children's smile, will be lost.
7. Abundance of money, power, and fame make people alone and enhance loneliness.
8. Cigarettes, Heroin, and Cocaine are harmful for our health. People still love to take it.
9. Smoking tobacco is good for the economy; smoking helps the government. On the other hand, tobacco is the second major cause of death in the world.
10. Stressful relationships in student life and professional life can ruin a successful career.
11. Nobody cares unless you are beautiful, rich, popular or dead.
12. Most social media based celebrities are the greatest losers in real life.

Besides, there are some other dark lessons life showed us :

The world only cares about what it can get from you. -David Wong*

The secret of life is… everything is out of control. - Ajahn Brahm

The devil has not vanished simply because people refuse to believe he exists, no more than God has... (E.A. Bucchianeri, Brushstrokes of a Gadfly).

Keeping secrets is a survival tactic. - Kaede Lazares

If you’re sluggish, you’ll be ridiculed by your boss. If you’re proactive, you’ll be hated by your colleagues. (source- Manxp)

Where is the least likely place for life in the universe?

The largest known galaxy in the universe, IC 1101, might be one of the least likely places for complex life to exist. If this galaxy nevertheless hosts multicellular creatures on planetary surfaces, their conditions for survival are extraordinary. Microbial life could subsist in subsurface oceans or brine pockets, even in quite extreme places in the universe.

IC 1101, located a billion light-years from Earth, is in a league of its own. It contains a staggering 100 trillion stars. In comparison, our Milky Way hosts only 100 to 400 billion. However, it will not get any more of them, as it had already run out of gas for star formation 10 to 11 billion years ago, when the universe was 3 to 4 billion years old, or 5 to 6 billion years before our system formed. It forms zero stars a year on average.

This means that in IC1101, more stars are red dwarfs than in our galaxy. All huge, blue, and hot stars exploded as supernovae when the universe was already very young. Stars like the Sun already transformed into white dwarfs, and if any hosted technological civilizations like ours, they either went extinct or had to move to other systems to survive.

It’s an open question if red dwarf stars, which can exist up to 12 trillion years, can host complex life on the surface. Such stars flare and can damage the atmospheres and oceans of planets in their habitable zones, which are tight because these stars are not as hot as our Sun.

Furthermore, not all stars can host surface organisms and technological civilizations in IC1101. About half of the stars have a safe Rosetta orbit, which is centrophobic. The rest experience infall into the center of this vast galaxy on each revolution.

Not all is lost, though. This galaxy is so immense that one orbit can take 2 to 4 billion years in the galactic edge zone where tens of trillions of stars reside, so even stars on boxy orbits can develop their own technological civilizations on a revolution around their galaxy. Additionally, boxy orbits don’t always take stars to the center of the galaxy; they can also take them relatively far away.

However, over 11 billion years and among 100 trillion stars, there might have been dramatic extinctions of complex surface life and technological civilizations due to infall into the galactic center, and this journey was extraordinary.

Some doomed systems and their planets would reach speeds of 0.5% to 4% of the speed of light during this infall because the gravitational potential of IC1101 is so extreme. During the lifetimes of individuals living on these worlds, stars would visibly move, and making out constellations would not make sense.

The center of the galaxy is inhospitable. There is a lot of radiation from high-density stars and the supermassive black hole. Stars are positioned very close to one another, and there is a high chance of interference with infalling star systems with living planets. These worlds could be ejected and become ultracold rogue planets; planetary systems could be disrupted, and planets could collide with other planets or stars, resulting in destruction. Systems’ asteroid fields can be disturbed, causing intense bombardment of living planets. It could result in tragic extinction events.

For sentient species to be subject to such a sorry fate must have been immensely sad and dramatic. Hopefully some could have developed advanced enough technology to leave their system on time for a safe one with a Rosetta orbit.

What are some of the dark lessons that life showed you?

Food is love , Survival, friend , oxygen!

1. If you have money then people will ask you if you need money then tell them.This is the bitter truth.
2. Outsiders are more supportive than family members.
3. Those who talk sweetly to you actually love your money.
4. Nothing will happen without hard work, taunts make a person strong.
5. Time is very powerful, it can turn a king into a pauper.
6. When you are a student, you want to grow up quickly but after growing up you realize that student life was the best.
7. Being a father is a difficult task. It's important to take along with you children, wife, family, and society.

What is the saddest but truest sentence about life?

 People think they are much more important than they actually are.

The Earth could explode tomorrow and the universe wouldn't even notice.

We are so tiny and insignificant in the universe that it's not even funny.

For example, look at these pictures.

Now look at the Earth:

And now look at Earth compared to Jupiter and Saturn... pretty wild.

…but then you compare it to the sun and the earth is a speck of dust.

And you might think, "The sun is quite impressive"—actually, it isn't. Compare it to these other stars in the Milky Way galaxy...

Let's take a look at how large Arcturus is in the image above (which is smaller than our Sun) compared to some larger stars in the Milky Way.

Antares must be a gigantic, impressive star, right? Let's take a look at it in the Milky Way... I bet it stands out!

Is the Milky Way an impressive galaxy?

Not really. There are trillions of others in the observable universe.

We humans like to think we are important, but on a large scale we simply are not.

What are some survival tricks that could save your life someday?

 1. If you sink, scream

If one day you find yourself on a sinking ship, and somehow you manage to break free, be careful. Once the air is neutralized, if you are low enough, the water pressure will kill you and your lungs will collapse. To avoid this, shout your way to the surface. No joke, while you swim, you must shout; this will prevent the pressure from killing you.

2. Deep wounds

Do NOT use hydrogen peroxide on deep wounds, as this hinders the healing of the blood. It is fine for small cuts, but NEVER for a deep wound.

3. Neck injuries

When you see someone whose neck has been cut and is bleeding heavily, locate the carotid artery and cover it to stop the bleeding. This will allow emergency services to arrive.

4. In case of fire

Fires spread surprisingly fast. People tend to imagine that a fire burns on the ground or in a corner of the house and stays there for a while, but it can spread through the roof and walls, so don't grab anything and run!

5. Lost and without water

If you are lost and without water for more than two days and have to choose between drinking untreated water or not drinking at all, drink it. If you don't, you will die of dehydration very soon, and the illnesses you can get from drinking dirty water take a few days to develop, giving you enough time to seek help.

6. If you are trapped in the high tide

If you are trapped in the high tide, swim parallel to the shore until you are out of it. Swimming directly back to shore will get you nowhere and will exhaust you, which is extremely dangerous.

7. If you are choking

You can perform the Heimlich maneuver on yourself when you are choking and there are no people nearby. Press your fist against your abdomen and lift. You should press your fist and your other hand against the diaphragm or stomach area. Add force with a stable object, such as a chair. Repeat the process until the obstruction is cleared.

8. If you see someone fall on the ice

If you see someone fall on the ice (river or lake), lie down on the ice and crawl towards the person. DO NOT walk on the ice. By lying down, you reduce the likelihood of falling as well, and therefore both of you would be in the same situation.

9. How to identify a stroke?

Quickly, look at the face, arms, conversation; time is of the essence. If the person has an uneven smile or part of their face is "drooping," if they raise their arms and one of them falls or they can't raise them high enough, if their speech is slurred or unintelligible, ACT QUICKLY! Call an ambulance immediately.

10. If you are stabbed

What mistake could be fatal in the life of a Hollywood actress?

 At 31 years old and already with two Oscar nominations in her career, star Margot Robbie said:

Auditions terrify me; I get nervous even when I know I'll get the part. I still get very nervous; I find auditions truly frightening.

A short time later, she recalled an incident that marked her life as an actress: “Oh my God, I did a terrible audition once. It’s a long story…”

"In America, obviously, the names of the drugs are different than they are in Australia," Robbie said.

“I had minor surgery the day before a big audition that I really wanted the part for, and I was in a lot of pain. I was at my friend’s house and he had just had a root canal. I was like, ‘I’m in a lot of pain, but I have this audition tomorrow.’ And he said, ‘Well, I have root canal painkillers. Take them as soon as you wake up, before the audition, and you’ll be fine.’ And I said, ‘Okay, thank you,’” the actress continued.

The next day, he offered the actress two pills, which she ended up taking both at once.

When he said, 'Take two,' I thought he normally took two as a dosage , but in fact he intended to take two in case I needed another one later,” she recalled.

“Finally, I woke up and was getting ready for the audition. I didn’t have time for breakfast, so on an empty stomach, I had two. I was driving and suddenly I was like, ‘Oh my God, what a beautiful day it is!’ I reached out the window. I was high… It was a horrible audition, I’m sure!” said the actress.

On the same day, the actress still needed to take her driving test in the United States.

“I was heading to my test drive right after getting my American driver’s license and I thought, ‘I’m not feeling well, I can’t do the test drive.’ Luckily, my friend worked at Sony, where I was taking the test, and I ran into her office and said, ‘Can you get me some food or something? I think I’m high. I’m not sure, but I think I’m really high, help me.’ It was hilarious,” Robbie added.

What place on Earth would be more inhospitable to human life?

 Unexpectedly, it's neither the Sahara Desert, nor the icy plains of Antarctica, nor the dangerously deadly Amazon rainforest…

Ladies and gentlemen, I present to you Rannoch Moor , in the heart of Scotland.

Rannoch Moor is only six kilometers in diameter and doesn't seem so bad. But a few years ago, one of those crazy people who want to conduct survival experiments decided to challenge Rannoch Moor.

See that beautiful hut? Well, that's where they found 29-year-old David Austin, dead from hypothermia after trying to survive on Rannoch Moor.

The problem with this place is that it's very flat and open. And worse: the ground isn't solid. It's an area full of moss, where you'll walk through muddy swamps and soggy marshes.

There's nowhere to rest. There are no trees. There's no dry land. And if you try to cross Rannoch Moor even a little bit faster than normal, you're quite likely to badly twist your ankle.
