Different computations provide different values for the number of galaxies in the observable universe — that is, the part of the cosmos visible from Earth with current technology; there may be many more, but they are just too far for our telescopes to detect. Using Hubble Telescope data, researchers determined that the visible universe contains around 170 billion galaxies.

This is more of a theoretical ideal than a reality, but numerous fields of mathematics, quantum mechanics, and astrophysics have all reached similar conclusions: our world is just one among many, and we live in a multiverse.' There are several theories as to how this may happen, one of which being that atoms can only be organized in a finite number of ways in time and space, eventually leading to the repetition of events and individuals. Other ideas postulate bubbles or parallel universes, as well as 'braneworlds' that exist just outside the grasp of the dimensions we know.

According to the ADAA, from the time a girl reaches puberty to the age of 50, she is twice as likely to develop an anxiety disorder as a man. A woman’s fight or flight response is more easily activated and stays activated longer than a man’s – partly due to progesterone and estrogen. There’s also evidence to suggest that the female brain does not process serotonin as quickly as the male brain and they are more sensitive to low levels of corticotropin-releasing factor (CRF), a hormone that organizes stress responses in mammals.

This may sound fantastical, but practically every element found on Earth was generated in the blazing core of a star, including all of the elements that make up life on Earth, therefore our bodies are comprised of stardust. NASA has conducted significant studies on stardust, and you can learn more about their findings on their official website. The image above shows a NASA stardust container. "The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were produced in the guts of falling stars," Carl Sagan writes. "We're formed of stardust."

According to the CDC, approximately 7% of children between the ages of 3 and 17 years old have been diagnosed with anxiety. Since children are still developing their verbal skills they can’t say, “I have anxiety” or “I’m really worried.”
Instead, their anxiety shows up in complaints such as stomach aches, headaches, or behavioral issues like temper tantrums. Other common anxiety symptoms in children include restlessness, inattention, avoidance, and frequent meltdowns. Sadly, these symptoms often get misdiagnosed as ADHD – and then medicated. 

According to research at Harvard, anxiety has been indicated in several chronic physical illnesses, including heart disease, chronic respiratory disorders like COPD, gastrointestinal conditions such as IBS, and substance abuse. There is still a lot to learn about the way our body experiences anxiety and how it affects our physical health. However, what is certain is that long-term exposure to increased cortisol levels (i.e., anxiety) leads to decreased immunity and damage to the heart and lungs.

Most people know that anxiety causes difficulty focusing and concentrating, restlessness, irritability, and frustration. However, few people realize that anxiety causes serious physical problems like weakness, shortness of breath, rapid heart rate, nausea, hot flashes, and dizziness. People experiencing a panic attack often end up in the ER believing they are having a heart attack.
 

Because individuals who suffer from anxiety often struggle to stay in the present moment, it makes them often forgetful. People who suffer from generalized anxiety disorder struggle with worry and an inability to control the worry. When we worry, it’s often about something that hasn’t happened yet, meaning we are thinking about the future – where problems may occur. This is why people who suffer from anxiety often appear like they’re distracted, not listening, or just don’t care.

Have you ever wondered why your hands and feel sometimes feel cold to the touch? Did you know that it could be the result of anxiety? When we feel anxious, the flight or fight response kicks in. When this occurs, blood flow is redirected from your extremities, such as your hands and feet, and towards the torso and vital organs. This creates the feeling of cold in your hands and feet.

A common, but the lesser-known side effect of anxiety is anger. When we feel powerless over a situation, or our life is out of our control, expressing anger is a natural way to feel a sense of control.
It’s much easier to externalize the conflict rather than acknowledge the real issue and deal with it. Additionally, with chronic sufferers of anxiety, depression sometimes develops.

Why do some survive traumatic events and come through seemingly unscathed? And yet others develop anxiety disorders like PTSD, Panic Disorder, and Generalized Anxiety Disorder. One thing is certain: anxiety disorders and anxious temperaments seem to run in families. Studies also show that individuals who are genetically predisposed to anxiety are at a higher risk of developing anxiety after exposure to traumatic or stressful events.

Anxiety is often a cause or a trigger of depression. Research indicates women who have generalized anxiety disorder are at an increased risk of developing depression. People with chronic depression often develop symptoms of anxiety as a result of the mental exhaustion of depression. The same is true for sufferers of chronic anxiety. For example, people who struggle with Social Anxiety Disorder often develop depressive symptoms as a result of lifestyle choices made to accommodate the symptoms of Social Anxiety Disorder, such as avoiding others and public places.

The Ambassador was once a terrific option for families and was the first automobile ever produced in India. The first one came out in 1957, about 70 years ago. It had adapted quite well to our society and is still lovingly remembered by all of us.

The only creatures that live permanently on Mt. Everest are jumping spiders. Jumping spiders lurk in nooks and crannies on the slopes of Everest at a height of 6,700 meters (22,000 ft), making them one of the Earth's highest permanent dwellers. Animals such as the snow leopard, Himalayan tahr (a goat-like species), and Himalayan yak may be found below an elevation of 6,000 meters.

Kabaddi may now be a foreign sport to the Olympic stage, but many don't realize that it first acquired international exposure when India showcased the sport during the 1936 Olympics in Berlin, leaving Adolf Hitler and Olympic Committee members in amazement with their kabaddi manoeuvres.

Noel Odell, an adventurer, was the first to uncover marine fossils on Mount Everest in 1924, proving that the Mount Everest area was formerly covered by an ocean. The summit's limestone and sandstone were discovered to be submerged sedimentary rocks produced roughly 450 million years ago. Geologists believe Everest has only been a mountain for around 60 million years, when the Indian Plate was subducted by the Eurasian Plate, generating the Himalayas. If that's the case, Mount Everest must be growing quicker than in the past, as it would only take around 2 million years for Everest to rise 8,848 meters at current rates of 4 mm/year.

Because the International Space Station (ISS) has Russian-language modules and operations, all astronauts who travel to the ISS must be fluent in the language. According to some astronauts, learning this new language was the most difficult aspect of their training. English-speaking astronauts can expect to spend 1,100 class hours to reach a reasonable level of fluency in Russian, according to the US State Department Foreign Service Institute. That's twice as long as it takes to learn other languages such as French, Spanish, or Dutch.

While the earliest automobile races occurred long before WWII, Formula One did not formally begin until 1946. The inaugural race was held at Valentino Park in Turin, Italy, and was won by a driver in an Alfa Romeo 158. This event was part of Achille Varzi's spectacular recovery from a drug-fueled past. The inaugural race was held in 1946, but the first world championship would not be held until 1950. On May 13th, 14 teams and many independent drivers competed in the championship race, with Giuseppe Farina claiming the win.

Convertibles have a tremendously exciting and romantic feel about them. Even though the country was not equipped for open-air automobiles and the heat, many Indians enjoyed the Standard Herald when it debuted in 1965. However, it is an excellent option for friends and families that wish to travel together. For decades, this automobile could be spotted on numerous Indian roadways.
