“Gravitational Waves” found yet again!

Here’s a quick update…

Last year in september, for the first time ever scientists Laser Interferometer Gravitational-Wave Observatory (LIGO) have observed Gravitational waves. The source of these waves were the product of the collision between two black holes into a giant single black hole occured 1.3 billion light years away

On December 16 2015 LIGO observatory for the second time detected a signal, which now confirmed as Gravitational waves. The scientists at LIGO converted these gravitational waves into sound waves, here’s how they sound!

This yet again proves the Einsteins theory of relativity..
When two dense objects such as neutron stars or black holes orbit each other, space-time is stirred by their motion and gravitational energy ripples throughout the universe.

What’s your speed right now?

Are you just resting and reading this right now? Even then, you are moving with a great speed! By now you might have guessed what I am gonna talk about “The earths rotation”. Let’s go deep into space…

Let’s start small, as you move from the earths equator to the poles your rotation speed decreases. As the equator is the fastest at 1600kmph! Even with small speeds of cars, we inside the car feel the speed, then at that great speed of earth, we don’t feel a thing! why?

Because, earth is moving at a fixed rate, and we’re all moving along with it, and that’s why we don’t feel Earth’s spin. But in case of a car, the speed isn’t uniform. If Earths spin were suddenly to speed up or slow down, you would definitely feel it.

Let’s get back on track. Earth is travelling around the Sun, the Sun moves around the center of Milky- Way, the Milky-Way moves within the local group of Galaxies, these local groups moves within the Vergo cluster and so on…. As of now that is all we know! And that’s a stupendous speed…

The speed of moon from earth is different from the speed of moon observed from somewhere in the space. This is because the speed is relative. There is nothing called absolute speed. Even rest is relative. But the change in speed is same or absolute.

And again we are on the earth and the earth is “in” the system moving with the same speed as the system. So we don’t feel and thing.

And we are puny little beings in this gigantic universe travelling with a tremendous speed, ” which we don’t feel a thing”;)…

 

GLOWING PLANTS!

Ever thought of trees glowing? Maybe now you should.. So, technical name for these type of plants is Bioluminescent plant. The first bioluminescent plant was made in 1986, with the addition of firefly luciferine.

There are a few species like jelly fish, fireflies etc.. On our planet that can glow. To make the glowing plants, the team first uses the Genome Compiler software to identify a plant’s DNA. The software then custom prints the sequence and then inserted into a plant.

The main sequence responsible for making the plant glow is known as luciferase (it can also be found in fireflies). Unlike the previously made Bioluminescent plants, where the plants aren’t so bright,  now scientists have been able to get the gene to recycle itself and make the plant especially bright.

Scientists say that the intensity of the light emitted by these Bioluminescent plants isn’t that high to replace streetlights. Hopefully someday we replace our street lights and table lamps with Bioluminescent plants.

Misconceptions about tides! What really causes tides?

Many people get it wrong about the reason for gravity of moon and sun responsible for tides. Now, let me ask you something, why don’t we see tides in a lake? And why don’t we see sand and rocks levitate, Due to the Gravity of moon and sun?

Let’s see what actually cause tides. When you are in an accelerating bus( technically in an accelerating frame or non-inertial frame), what ever may be the mass of the object, they  experience force while bus turns, in a direction opposite to the turn. This force is similar to the Tidal force experienced by earth.

Here, what ever may be the mass of the object on earth, they should move out of the surface of earth. But that’s not happening here, all the objects aren’t moving out. The tidal force isn’t acting only on the moon-earth line, because if that was the case ( tidal force acting along the moon earth line), we should see the lakes, ponds, rocks, you and me raising, but we aren’t. And the tidal acceleration due to the gravity of moon along the earth moon line is 1/10,000,000th gravity of earth, so it is not possible for this tiny force to lift something on earth. But that tides are real here!!!!

Then, what is really causing tides???

Until now, we only have considered forces on the earth-moon line. Now consider the forces acting on some other points on earth, the resultant of the forces at that point, i.e., the TIDAL force at that point is observed to be radially downward. By mapping the direction of tidal force at various points on earth, it looks something like the image down below. With the image below, it is clear that, this force is not lifting or stretching but getting SQUEEZED.

From an unknown source on the internet, I have read that this phenomenon is similar to that of squeezing a pimple;);) So true.. This makes it easy to answer my above question “Why do lakes don’t have tides?”. Well… You got it, they are like small pimples, hard to blast:);). They have a smaller surface area and have tiny microscopic tides, which can’t be seen. By the way, the similar is the case with sun. The Sun is very far from earth yet with a huge mass. So,according to the position of the sun, earth and moon the bigger and smaller tides are formed!

Let me know, what you think!

Spherical Tires!!!


Spherical tires, this may sound crazy, but they are actually awesome. Unveiled at the Geneva International Motor Show, by a company called “GOODYEAR”.

These tires allows cars to move in all directions, with spherical tires, you can even slide in sideways too. Greater parking efficient, so existing parking lots can accommodate more cars without taking up any more space. But, how on this earth, they fixed the tires to the car, yet manage to make them rotate in every direction?

Well… They used magnetic levitation, rather than axles, to suspend the tires under the cars body.. Where an object is suspended above another with no other support but magnetic field.

These are 3d printed, and are smart enough to detect, whether the road is wet or dry, and functions accordingly. The coral-patterned tread also behaves like a natural sponge – responding to wet weather by softening, while stiffening in dry conditions. Here are my previous articles on 3D printing and even 4D printing 😉 (3D printing , 4D printing ).

 

 

 

 

 

Hurrah! My blog turns an year now…

Hurrah! It’s been an year now. One thing’s for sure, blogging community here is awesome. I learnt so much here. Now, my blog turns an year and I got an year of experience in blogging. This is a huge thing to me. So, I thought, why not make this article a huge one too. Before you get mad at me scrolling down and down and wondering where it ends, let me explain you something.

When I did my 100th article with 100 followers (Celebrating 100th article with 100 followers). I thought I would write my 200th article with 200 followers but, it didn’t happen now. This is my 153rd article with 210 followers;);) The funny thing is I got the followers count, as I said before  bloggers here are really awesome, but I didn’t reach my articles count;);) It’s pretty genuine though, you don’t want to read junk and I don’t want to write articles to just satisfy the count.

Moving on, as you scroll down, hopefully you find some really interesting articles. And there are so many of them. Trust me you won’t be disappointed because, all my favourite articles are listed below. The good thing is, almost all of my articles are listed. Favourites till my 100th were listed in one article and from 100th to this particular article are listed below. So, this is an eye feasting article, atleast to me;)

If you have read and still remember my 100th article you might have noticed that, a few dialogs are similar right? Yeah! In case you don’t reach the end of this article reading and scrolling, let me tell you something. Thank you so much for making this happen, thank you for your support and thanks for your suggestions. Appreciate it!

What is Supernova?

In astronomy, we often hear the word “Supernova”. Let’s see, what actually a Supernova is?

 Supernova is an event where an explosion of a huge star takes place. These blasts produce some heavy material in the universe including some elements, like iron, which make up  planets. Not all stars become Supernova though.

So, there are two types of supernovae.

White Dwarfs

White Dwarfs is something with the size of our earth and with 8 times the mass of our sun. This explains how dense it is. With this high density, it pulls mass from the neighbouring mass, using its gravity. By taking in the mass, it reaches a level called “Chandrasekhar limit”. At this instant, the star becomes unstable and supernova takes place. In turn, it forms something called Neutron star.

Star Fusion

 It occurs when stars core’s fusion process runs out of fuel. They can briefly outshine entire galaxies and radiate more energy than our sun will, in its entire lifetime. Stars are high nuclear reactors producing energy by fusing hydrogen into helium. Running out of fuel is nothing but, running out of hydrogen. With this, the helium is fused into heavier elements and supernova takes place, adding enrich elements to space clouds of dust and gas, further interstellar diversity, and produce a shock wave that compresses clouds of gas to aid new star formation.

Ultimately these supernovae are responsible for Black-holes and Birth of new stars too…

Epic moment in science( Discovery of Gravitational Waves)

For so long, scientists were trying hard to find the evidence for Gravitational waves, predicted by Einstein over a 100 years ago, in his “Theory of Relativity”. Finally, scientists at LIGO( Laser Interferometer Gravitational Waves Observatory) detected Gravitational Waves.

Scientists estimate, about 1.3 billion years ago, two black holes  collided at half the speed of light. Which resulted in Gravitational waves. Detector at LIGO detected these waves.

LIGO has two identical detectors, one located in Livingston, Louisiana, the other in Hanford, Washington. These Detectors can detect even very little vibrations from Gravitational Waves.

Learn more about gravitational waves here”Gravitational Waves“. Also about the origin of our universe, cosmic inflation here” Origin of our universe“.

This discovery changes our perspective on how we see the Universe.

What if we were like “Flash”? Science of Flash!!

You might be knowing the Flash. For those who don’t know Flash, Flash is a DC Comics character with super speed. So much speed that he can travel in space and time( back and forth in time). Which means at the speed of light!!

 The Flash could not realistically do what he does. Let’s see what we need, to do what he does.. To move at such greater speeds, we need energy, for which we need to eat at super speed too!!!

At such greater speeds there is something called air resistance. Just try running on a windy day in the opposite direction to the wind, you will know what I am talking about. With this air resistance we may be on fire, because of the friction between the air and our body, once we achieve higher speeds.

Well… Writers are clever enough to introduce something called force field to explain this, which The Flash gets through a failed experiment( particular accelerator).

In recent articles, we have learned that, even light takes some time to do things. Which means, to see things around, light should travel from the object to the eye, from the eye to the brain, then our brain processes that information and finally we actually know what’s going on. Seems that when we look our self in a mirror, we actually are looking at a few nano seconds past image.

We see the world in maybe 60 fps (frames per second), which we think is really present. Some animals see the world in 240 fps and I can’t imagine, how flash see the world. Maybe, in his perspective the world is paused.

So, what do you think?

 

 

 

Move back and forth in time( TIME DILATION)

Time dilation leads us to time travel!! Sounds great, but kinda weird to explain. Your concept of relative speeds doesn’t work here.

If you and superman are flying with the same speed, then with respect to you, the superman is at rest. This isn’t the case with light, as long as your speed is less than light( though your speed is so close to light), the speed of light doesn’t change with respect to you.

If speed isn’t changing with respect to you, though you are moving, then what is changing? Well… The time is changing. So, this is the key for time travel.

Have you watched the movie “Interstellar”? Yeah you must. When the hero returns to his daughter from another planet probably in other solar system, his daughter becomes more than 90 years old( that is much older than her father). This is time dilation, because of his journey through wormhole.

You could do a flyby of a nearby star and return to Earth at nearly the speed of light, and a few years would pass on Earth while possibly only a few weeks or months would pass for you, depending on how fast you were going and how far away the star was.

Few of my recent articles are related to this one.  RELATIVITY (all about the Einstein’s special and general relativity) and the previous one Stars ( which proves that, even light with such great speed takes “Time” to reach us;)

There is another extension to this article, can you guess one?
