Expansion of Space

When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang.

The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you.

However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else. If you imagine a grid of space with a galaxy every million light years or so, after enough time passes this grid will stretch out so that the galaxies are spread to every two million light years, and so on, possibly into infinity.

The universe encompasses everything in existence, from the smallest atom to the largest galaxy; since forming some 13.7 billion years ago in the Big Bang, it has been expanding and may be infinite in its scope. The part of the universe of which we have knowledge is called the observable universe, the region around Earth from which light has had time to reach us.

One famous analogy to explain the expanding universe is imagining the universe like a loaf of raisin bread dough. As the bread rises and expands, the raisins move farther away from each other, but they are still stuck in the dough. In the case of the universe, there may be raisins out there that we can’t see any more because they have moved away so fast that their light has never reached Earth. Fortunately, gravity is in control of things at the local level and keeps our raisins together.

Who Figured This Out?

The American astronomer Edwin Hubble made the observations in 1925, proving that there is a direct relationship between the speeds of distant galaxies and their distances from Earth.   The observation that galaxies are moving away from the Earth at speeds proportional to their distance has traditionally been known as Hubble’s Law, although it should be noted that, in 2018, the International Astronomical Union (IAU) voted to recommend amending the name to the Hubble–Lemaître law,  in recognition of the contributions of both Hubble and the  Belgian astronomer Georges Lemaître to the development of modern cosmology.

The Hubble Space Telescope was named after Edwin Hubble, and the single number that describes the rate of the cosmic expansion, relating the apparent recession velocities of external galaxies to their distance, is called the Hubble Constant.

Is the Universe Infinite?

It might be easier to explain about the beginning of the universe and the Big Bang Theory, than to talk about how it will end. It is possible that the universe will last forever, or it may be crushed out of existence in a reverse of the Big Bang scenario, but that would be so far in the future that it might as well be infinite. Until recently, cosmologists (the scientists who study the universe) assumed that the rate of the universe’s expansion was slowing because of the effects of gravity. However, current research indicates that the universe may expand to eternity. But research continues and new studies of supernovae in remote galaxies and a force called dark energy may modify the possible fates of the universe.

THE LAW of ATTRACTION [LOA]

WHAT EVER YOU THINK, COMES BACK TO YOU. THE UNIVERSE IS JUST LIKE A MOUNTAIN, WHEREIN YOU SHOUT , THE VOICES ECOES AND COMES BACK TO YOU. IT IS SAID EVERY POSITIVE THOUGHT IS TEN- THOUSAND TIMES STRONGER THAN A NEGATIVE THOUGHT. WHY IS IT SO, YOU MIGHT WONDER ? IT IS THE UNIVERSE, WHO LISTENS TO WHAT EVER YOU ARE SAYING. WHEN YOU MAKE A THOUGHT, THE UNIVERSE CONSPIRES TO MAKE IT HAPPEN. FOR INSTANCE; IF YOU ARE WITH YOUR MOM AND APPRECIATE HER FOR WHAT SHE HAS MADE, SHE WILL GIVE YOU ANOTHER PORTION TO EAT. SIMILARLY, IF YOU THANK UNIVERSE AND PAY GRATITUDE TO IT, IT WILL SURELY DO GOOD TO YOU.

A HUMAN MIND GETS LOADS OF THOUGHTS THROUGHOUT THE DAY, WE CANNOT STOP OURSELVES FROM THINKING. BUT, WE CAN SHIFT OUR THINKING TOWARDS POSITIVITY. A HUMAN MIND CAN DO WONDERS. NOTHING IS UNACHIEVABLE. IF YOU HAVE SOMETHING IN MIND, YOU CAN BRING IT TO REALITY. WHY CANT WE? SUCCESS DOES NOT STOP ITSELF FROM COMING TO YOU, IT IS YOU WHO THINK THAT WE CANT SUCCEED. WHAT EVER YOU THINK IS ACHIEVABLE.

THANK THE UNIVERSE FOR WHAT YOU HAVE GOT. THANK IT FOR WHAT IT WILL GIVE YOU. STAY THANKFUL AND PAY GRATITUDE, THE UNIVERSE SHALL ALWAYS BE THERE TO HELP YOU.

Good and Evil

KARMA

WHAT IS KARMA? KARMA IS JUST LIKE; IF YOU SPIT IT THE AIR, IT FALLS OVER YOU. KARMA COMES BACK, IS IT TRUE? YES, IT IS. IF YOU DO GOOD TO PEOPLE, GOOD WILL HAPPEN TO YOU. IF YOU DO BAD TO PEOPLE, ONE DAY OR THE OTHER YOU SHALL GO THROUGH SOMETHING NEGATIVE. YES, IT IS TRUE. I HAVE EXPERIENCED A LOT OF INSTANCES, WHEREIN I HAVE WITNESSED PEOPLE GOING FROM LAND TO SKY, AND THOSE WHO DROPPED FROM THE SKY TO LAND.

WHAT YOU GIVE, COMES BACK TO YOU. WHAT YOU DO COMES BACK TO YOU. IF YOU THROW, 2 BALLS IS THE AIR, IT COMES BACK TO YOU.LET US USE AN EXAMPLE: BLUE BALL STANDS FOR BAD KARMA AND PINK BALL STANDS FOR GOOD KARMA. IF YOU DO GOOD, IT WILL GET TO YOU; THINGS WHICH ARE POSITIVE. EVERY NEGATIVE KARMA COUNTS AND SO DOES A POSITIVE KARMA. IF YOUVE DONE BAD TO PEOPLE , ITS CONSEQUENCE WILL COME TO YOU EVEN IF YOU HAVE DONE GOOD TO PEOPLE.

BE POSITIVE, DONT GET JEALOUS OF OTHERS. YOUR LIFE WITH BE THE WAY YOU THINK OF IT TO BE. YOU ARE THE MASTER OF YOUR LIFE, THE ARTIST OF THE ART CALLED “LIFE”. BLESS PEOPLE, THE BLESSINGS WILL MULTIPLY AND COME BACK TO YOU. IF YOU BE GOOD TO OTHERS, YOU SHALL ALWAYS HAPPY.

STAY HAPPY AND RADIATE HAPPINESS.

International day of Tropics

The serenity of the lulling ocean is a wondrous thing to behold..more precious than the gems coveted and covered in platinum or gold…

Oksana Rus

Introduction

International day of Tropics is observed every year on June 29th . This day is celebrated to highlight the different challenges and opportunities faced by the nation as well as by the people who lived in tropical areas .

Firstly , you want to know about things like :

What are tropics ?

Why we celebrate international day of Tropics ?

Or

Is it worth it to talk about these things and is it really important ?

Well hold your horses and try to calm .

What is tropic day and why we celebrate it ?

Well a tropic day is celebrated to highlight the importance of Tropics , it signifies extraordinary and astounding diversity of tropical nations .

The Tropic defined as a area /region between tropic of Cancer and tropic of Capricorn . The day aim at promoting tropical regions and awareness to the people about the diversity of these regions .

While these regions go through little seasonal changes on day to day basis because of some factors like tomography , climatic variation that causes changes in temperature and make these regions warm.

This day introduced to the world when in June 29th , 2014 twelve leading tropical research institutes come together and collaborate. The inaugural state of the Tropics report was launched . The report offers some unique perspective for the increasing the importance of these regions .

United Nations General Assembly adopted resolution A/RES/70/267 in 2016, which declared that 29 June of each year is to be observed as the International Day of the Tropics.

The International day of Tropics briefly explained the issues affecting the tropical zone’s all over the world. To raise awareness and important role the countries played to Sustainable goals .

International day of Tropics 2021

As per the state tropics report the theme of this year is “ THE DIGITAL DIVIDE IN THE TROPICS ”

With the record of sustainable development goals as well as developmental scope . The biodiversity of these regions are maximum and its loss is also greater there. Tropical regions comprise 98% world’s mangrove forests, and around 99% mangrove species.

Due to the subpolar zone the Sun is directly overhead which is one of the region of extinction of flora and fauna in the Tropics. The region is subjected to myriad and need immediate attention to ensure sustainable development.

More than 50% of renewable water resource could be founded their. But the threat lies which causes eviction of lives in the Tropics.

Importance :

Due to the problems it’s our duty as a human being to spread awareness about the implications in climate changes , deforestation , urbanization , global warming effect the biodiversity and lives in Tropics.

The International day of Tropics organize many events in which people share their stories , events and lives in these areas and formulate strategies to ensure the development of such regions .

You who sacrifice fortunes to see the luxuriance of the tropics or the polar lights of the arctic, must pay more dearly to see the One for whom the luxuriance of the tropics is poverty and the polar lights are a tallow candle.

LIFE HISTORY OF APJ ABDUL KALAM

Early life :
His full name is Abul Pakir Jainulabdeen Abdul Kalam. He was born on 15th October, 1931 in Rameswaram, Madras Presidency, British India which is presently known as Tamil Nadu, India. His father’s name was Jainulabdeen Marakayar who was a boat owner and imam of a local mosque. His mother’s name was Ashiamma. She was a housewife. He was the youngest of four brothers and one sister in his family. Even though his ancestors had numerous properties and were wealthy, they lost most of their fortunes by the 1920s. This is why Kalam was born and grew up during poverty.

Education:
He studied in Schwartz Higher Secondary School. Previously he had average grades but later he was described as a bright and hardworking student who had a strong desire to learn. He went to Saint Joseph’s College, Tiruchirapalli, then affiliated with the University of Madras. He graduated in Physics in 1954. In 1955 he moved to Madras to study Aerospace Engineering in Madras Institute of Technology. The Dean was dissatisfied with his lack of progress in a senior class project and threatened to revoke his scholarship unless the project was finished within the next three days. He met the deadline impressing the Dean who later said to him that he was putting Kalam under stress and was asking him to meet a difficult deadline. He narrowly missed achieving his dream of becoming a higher pilot, as he got ninth position and only eight positions were available in Indian Air force.

Career as a Scientist:
After graduating from Madras Institute of Technology in 1960 he joined the Aeronautical Development Establishment of the Defence Research and Development Organisation. He started his career by designing a small hovercraft but remained unconvinced by his choice of job. He was also a part of the INCOSPAR Committee. In 1969 he was transferred to the India Space Research Organisation (ISRO) where he was the project director of India’s first Satellite Launch Vehicle.

Presidency:
APJ Abdul Kalam served as the 11th President of India, succeeding KR Narayanan. He won the Presidential election held in 2002. His term lasted from 25 July 2002 to 25 July 2007.

Books written by Dr. APJ Abdul Kalam:
He played an important role in the second pokhran nuclear test in 1998. He was also associated with India’s Space Program and missile development program. Therefore, he is also called the “Missile Man” of India. He wrote many books. The name of these books are as follows:-

Race: today’s generation!

As I’m going to start this blog I would love to say everyone is perfect in their own personality, in their own perspective, in their own decisions. So it’s been a long time I had passed my school and now persuing my passion (not a course) ‘my passion’ so let me tell what is the main topic I’m talking about but firstly I’ll tell you a story which is real, so I was studying in 10th and one of my closest friend I can’t revel his name but his intrest was in painting and then he was confused that ‘bro what should I take as a stream in 11th’ so I told him what you love or in which you have your interest, but he said my father is telling me to take PCM (science, math) and he wants to take humanity but he was confused because his dad said if you’ll took humanity then there’s no future! And his dad told him take science-maths and then you cout prepare for IIT and he took science-math and just because he want to become a engineer and want to earn money! And he wasn’t happy as he wasn’t able to paint because of his studies and he wasn’t that good in studies so he was trying very hard but I said why I mean if you love to paint and you wanted to take humanity as your stream then did you took science and math just for the sake of money and even you don’t have intrest in science maths then why and he said because of my father. And this is my experience ladies and gentlemen he took science and maths he studied very hard and gave the exam for jee and he failed because he wasn’t having that intrest in PCM. And on the other hand he haven’t painted for more than a year and when he gave his exam and came back home he took his brush and painted and I’ll that art was one of the best of my friend as he hasn’t painted for a while which is more than a year but,

As i said ‘IF YOU HAVE INTREST IN A PARTICULAR FIELD, YOU’LL DEFINITELY WIN’ but if you don’t have intrest in that particular field you’ll definitely lose doesn’t matter who much you work upon it ‘HAVING INTREST IS THE TOP FACTOR’

For example, if you don’t love to cook and your mom said son just cook tonight’s dinner and you know how to cook but you hate it than Tonight’s dinner would be for the dustbin. I’m damn sure! I don’t love to paint and if you’ll say please make my sketch. Then I don’t know what I’ll make but after making that Sketch you’ll disown me I know.

But why you guys just want yurselves to put yur souls, your hard-work, your precious time and obviously money, in those things where you don’t have any Intrest in. My today’s generation just want to become a engineer, doctor, or a IAS.

Okay so, let’s take an assumption, if my friend was passed in that jee exam and he was selected in a college and becomes an engineer and was doing his job properly but what do you think he used to be happy and prosperous okay if you was at his place were you used to feel good and happy. Guys invest yourselves in those materials where you’re good at and where you’ll love your thing. Its not about that we should not listen to our parents but sometimes we should listen to ourselves too.

Astronomy- The Science of Space

When you look at the night sky, you admire the fascinating beauty of millions of stars and galaxies of the universe. Humans have looked in awe and wondered what those twinkling dots of light are, since ancient times. Due to their inborn curiosity, humans have found answers to their questions and ventured deeper into the unknown. 

Today, many spacecrafts have been sent beyond our little world -earth -and humans have even walked on the moon! All this has been possible only because of our thirst to know more. So, space has its own separate branch of science- Astronomy.

What is astronomy?

Astronomy is the branch of science dealing with the study of the universe. There are two major types of astronomy- observational and theoretical. In observational astronomy, many different types of electromagnetic waves like X-rays , gamma rays, microwaves, UV rays, infrared and visible light. Theoretical astronomy mainly deals with simulations and creating theoretical models to predict the observations.

Distance in astronomy

We know that the universe is a very very large place. So, to measure distance in the cosmos we need bigger units of length than kilometers: 

Astronomical unit(AU): It is used to define the distance between Earth and the Sun. 1AU is equivalent to 149 million kilometers (93 million miles). 

Light year(ly): It is defined as the distance travelled by light in one year. The speed of light is 300,000 kilometers per second. So 1ly is equal to 9.5 trillion kilometers(a lot right!).

Parsec: It is  defined as the distance at which the mean radius of the earth’s orbit subtends an angle of one second of arc. 1 parsec is equal to 3.26light years. 

Some fun facts:

  • The limit of the visible universe is about 46.5billion light years(radius) which equals to 4.4* 10^26metres (humongous!).
  • The universe is about 13.8billion light years old.
  • The universe formed as a result of the Big Bang-literally a single point expanded to form the universe!
  • The universe is expanding at the rate of 72 kilometers per second.
  • There are more than one hundred thousand million stars in our galaxy (the milky way). Imagine if there are trillions of galaxies like our own, how many stars would that be!
  • The death of the universe is not completely predicted yet. Some say that it will become a dark and cold place when all the stars die. Others say that the universe will end with “the Big Crunch”.
  • When you look at the sun, you look about 8 minutes into the past, since light has taken 8 minutes to reach us. 
  • The milky way has a supermassive black hole at its center- Sagittarius A*

Are we alone?

We haven’t found any other life in the universe but the search is on. Since there are billions of stars, the chances of them having earth like planets are high. So, there probably are “aliens” out there, we just haven’t found them yet or they haven’t found us yet. Sadly, the chances of having contact with a developed alien life like us are very low. However, that won’t stop us from looking. Hopefully, we will find them soon (and let them be friendly!).

Astronomy is a diversified branch with biology, geology, chemistry, mathematics and physics, all different types of fields coming together. There is a lot of scope for a great career in this discipline. Besides, who wouldn’t want to find out the secrets of the universe.
