THOUGHT OF THE DAY – 004

“Take up one idea.

Make that one idea your life;

dream of it; think of it; live on that idea.

Let the brain, the body, muscles, nerves, every part of your body be full of that idea, and just leave every other idea alone.

This is the way to success, and this is the way great spiritual giants are produced”

TIME TRAVEL & WORMHOLES – myth or truth

https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js

penserstudypoint.wordpress.com

At present, we are changing according to the time. Time not change according to us. But what if we change the time. Time travel An imaginary thought.

We don’t know if It will be future or past. It is like changing time’s direction to past or increasing time’s speed to future, but if it will be possible in the future, It may be travel to past.

According to relativity, Nothing can travel faster than light (3 × 10⁸m/sec.). At light speed, mass will be infinite (according to relativistic mass formula) . And the length of object will be zero (according to length contraction formula). But if we travel with the light speed, what can we see? Is there any color? Is there any boundary of anything? Only white light appears on moving with light speed. Everything is white.

At present, black holes are the best source to see the past. Where, light cannot even pass through. The body’s shape , space-time will be changed at light speed . 

Even if we travel with such a high-speed it will take 2000 years in reaching and coming back to Earth from a thousand light years away star(or any Terrestrial body in space). When you travel such a large distance, an atom, the smallest unit of matter also traveled to that distance, and it is amazing to imagine.

Wormholes

According to scientists, a wormhole is a cylindrical path between two heavy bodies in space. It is not from any science fiction movie. It is scientist’s thoughts. 

Wormhole forms by two giant bodies have very high gravity value like black holes. If a path is a thousand light years long, wormholes can make it a few million miles long. So, it may be a possibility to travel faster than light.

In 1835, Albert Einstein and Nathan Rosen called them Einstein-Rosen Bridge. Bridge that connects two, bodies that are light years far away from each others.

Worm holes are like tunnels in space connecting to distant bodies because space and time are flexible (according to Einstein). Through the wormholes we can cover very long distance in a very short period.

According to another theory we can travel with light speed. The theory proposed that, if we are stable and space can move. In this theory, a large heavy body contract the space with fast and alternately a negative mass, behind the large body, can expand that contracted space.

Negative mass is only a hypothetical Idea. It behaves just opposite of positive mass that we have.

Positive mass can contract the space while a negative mass can expand it. Due to this, we remain stable on a position and space can move.

If all this phenomena possible, we can cover large distance with speed of light by stay at a place without any change.

EMPHYSEMA – Medical condition 002

Emphysema

Emphysema is a lungs disease.it is develops after many years of continue smoking. Emphysema and chronic bronchitis are relate to a group of lung disease that known as COPD (chronic obstructive pulmonary disease).

Emphysema is a condition which is damage the walls of the air sacs (alveoli) of the lung. Alveoli are small, thin-walled air sacs. This is located in the end of the bronchial tubes deep inside the lungs.

A normal lungs is consist of about 300 million alveoli. when you are take a breath in the air and alveoli stretch drawing oxygen in and transporting it to the blood. When you exhale, the alveoli shrink, and carbon dioxide out of the body.

The alveoli and lung tissue are destroyed when the emphysema is develops .The tubes collapse and cause an Obstruction that trap air inside the lungs sometimes are fewer alveoli, less oxygen will be transport into the bloodstream.

cause

Any types of smoke such as cigarette, cigar is a major cause of emphysema. if you are inhel this types smoke, and you will suffer chronic diseases.

Symptoms

●Shortness of breath during physical activity.
• Coughing and wheezing.
• Long term mucus production.
• Fatigue

Treatment

• Pulmonary Rehabilitation
• Surgery and lung transplant
• Oxygen therapy

TUMOR – friend or enemy ?

A Deadly tumor is called brain cancer. they grows sharply and often strike or mob healthy areas of the brain.

Tumour is either be benign and malignant.

Malignant is cancerous

Benign brain tumors have not consist cancer cells and are usually slow growing.

Brain tumors are two different types. primary or metastatic.

Primary brain tumors start within the brain.

A metastatic tumor is made when cancer cells situated elsewhere in the body break down away and travel to the brain.

For this reason, metastatic brain tumors are nearly every time malignant, while primary brain tumors may be benign or deadly.

Brain tumors are arranged in classes or categories based on where the tumor is situated , the type of tissue involved .

the tumor is benign or deadly , and other factors. If a tumor is laid down malignant.

The tumor cell is examined by a microscope to determine how malignant they are.

Based on this analysis, tumors are rated, or graded, where level of malignancy from least to most malignant.

Factors that determine the tumor grade include how quickly the cells are growing, how much blood is supplying the cells, the presence of dead cells in the middle of the tumor (necrosis), if the cells are finit to a specific area, and how similar the cancerous cells are not normal cells.

Symptoms


• Blurred vision
• Headache
• Loss of balance
• Seizures
• Tingling and stiffness

Types

* Pineal tumor
• Astrocytomas
• Acoustic neuroma
• Choroid plexus papilloma
• Vascular tumors
• Chordomas
• Ependymomas
• Craniopharyngiomas
• Schwannomass
• Ganglioneuromas
• Meningiomas
• Glioblastoma multiforme
• Gliomas
• Oligodendroglioma
• Pituitary adenomas
• Primitive neuroectodermal

Treatment

Brain tumor are remove by surgery and other way like radiation therapy and chemotherapy, target therapy.

Understanding the concept of LIGHT SOUND

SOUND

Anything we hear around us is not is sound but vibration of particles. Vibration is a type of disturbance which propagates by particles of medium.

Sound is not travel but it is a wave that is transferred by particles in the form of vibrations (particles can only transfer the vibrations by one particle to second and 2nd to 3rd and so on by remain their positions).

Without particles, sound has no existence. Sound not travel in space because there are no particles in space. , so we transfer the information in form of signal in space.

Speed of sound in different mediums

Air – 343m/sec

Water – 1437m/sec

Glass – 4540m/sec

Iron – 5120m/sec

According to this, as the medium density increases sound speed also increases.

Effect of temperature- As temperature increases speed of sound increases.

The normal range of sound to hear anything for human is 20hz to 20000hz.

But minimum range of sound which a human can hear is 12hz and maximum is 28000hz.

The sound created by a volcano eruption in 1883 is in range of 180decibel and it can be heard up to 3000 miles (ca. 4,828 km).

the sound created by the explosion of nuclear bomb is in range of 240 to 280+ decibels.

So, we cannot imagine what will be the loudest sound.

LIGHT

Light energy is a traveling Photon which is a form of electromagnetic radiation. Photon is a bundle of energy. 

Speed of light is 3 × 10⁸m/sec. in vacuum. 

As dense as the medium the speed of light will decrease.

Nature of light-

Light has dual nature

1- wave nature- we consider the light have wave nature because light has the property of diffraction, refraction, and interference etc.

2-particle nature- light has particle nature because it emits electrons when it strikes on metal surface called Photoelectric effect.

mass of photon is zero.

Formation of light energy -when we provide heat to an object it is start to emit photons.

The number of emitting photons, depending on temperature of the object. 

Photon having a special property that they can never exist in stable form. They start to travel since their formation.

Intensity of light inversely proportional to square of source distance.

7 properties of light – 

reflection, diffraction ,refraction ,polarization, interference ,dispersion, scattering.

Visible light is made up of seven colors known as VIBGYOR.

V – Violet 

I – Indigo

B – blue

G – green 

Y – yellow 

O – orange 

R – red

Where red light has the longest wavelength while violet light has the shortest wavelength.

SUN – A BRIEF INTRODUCTION

The sun is a star, a hot ball of glowing gases at the heart of our solar system. It is the largest object and contains approximately 99% of the total solar system mass.

Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit. 

The Sun’s outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). 

the sun’s visible surface sometimes has dark sunspots, which are areas of intense magnetic activity that can lead to solar explosion.

The Sun’s period of rotation at the surface varies from approximately 25 days at the equator to 36 days at the poles. Deep down, below the convective zone, everything appears to rotate with a period of 27 days

Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth’s air pressure at sea level) is so intense that nuclear reactions take place

The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and aurorae. Though it is special to us, there are billions of stars like our Sun scattered across the Milky Way galaxy.

Average diameter: 864,000 miles, about 109 times the size of the Earth.

Mass: 1.989e+30

Rotation period at equator: About 27 days.

Rotation period at poles: About 36 days.

mean density: 1.410 (gm/cm^3)

Surface temperature: 10,000 degrees Fahrenheit.

Composition: Hydrogen, helium, Oxygen, nitrogen, carbon, neon, iron, silicon, magnesium, sulfur etc
