The visible universe most likely contains more than 170 billion galaxies.
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.
Ferrari did not come up with the trademark red colour.
A Ferrari may now be purchased in a variety of hues, including brilliant yellow, black, and metallic grey. However, there isn't a big variety of colors to pick from. The most iconic color for a Ferrari is, of course, red. In fact, most ardent collectors believe that the only authentic color for an iconic machine like a Ferrari is its signature red. Any other hue is a sin. Today, red Ferraris account for 45 percent of all sales. What you may not know is that all Ferraris were originally red. In the beginning, there was no other color option. The red paint is officially known as "Rosso Scuderia." And, while the color red has been synonymous with the Ferrari brand in recent years, it was never a clever market
The temperature across the Universe is the same.
The Universe contained the heat of the Big Bang flame. Because it had nowhere to go, it is still with us today. The strange thing is that its temperature – 2.725°C above absolute zero (–270°C), the lowest temperature imaginable – is nearly constant throughout. However, if we view cosmic expansion as a backward movie, we can see that sections of the Universe that are now on opposite sides of the sky were not in contact when the fireball of radiation burst free of matter. In other words, from the beginning of time, there hasn't been enough time for heat to move between them for the temperature to equalize. Astronomers remedy this by claiming that the Universe was considerably smal
Nobody expected that the first gravitational waves would be observed from a binary black hole system.
Gravitational waves were discovered for the first time on Earth on September 14, 2015. These ripples in spacetime, predicted by Einstein in 1916, were caused by the merging of two black holes in a faraway galaxy. In a nutshell, the power emitted was 50 times that of all the stars in the Universe combined. However, this was not the only amazing component of the event. Each of the black holes had a mass of about 30 solar masses. Because a black hole is what remains after the majority of a star explodes as a supernova, the predecessor stars must have weighed at least 300 solar masses. Such stars are quite rare nowadays. However, the two black holes may be leftovers of the very first generation of stars – assumed to be massiv
There may be an endless number of worlds.
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.
In our galaxy, there might be 500 million planets capable of hosting life.
Scientists looking for alien life concentrate on "Goldilocks Planets," which are planets that fall inside a star's habitable zone. Planet Earth appears to have just the ideal circumstances for life to exist - its distance from the Sun means the temperature is appropriate, water can exist as both a liquid-solid and a gas, and the perfect combination of chemical components is available to develop complex living forms. Other planets with comparable characteristics are referred to be Goldilocks worlds. There are 500 million possible Goldilocks planets in the Milky Way alone, therefore if life can exist other than Earth, there are a plethora of potential worlds on which it may thrive. If these figures are exten
Women Are Twice As Likely As Men To Develop An Anxiety Disorder
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.
Exercise Can Help Reduce Anxiety
Countless studies show exercise helps decrease symptoms of anxiety. Did you know that a single workout has been proven to be a quick mood booster? And it doesn’t matter if the exercise is intense. It can be a quick walk around the block or a 30-minute run.
Anxiety can also be a good thing. It can keep you safe. Walking to your car alone late at night? Anxiety can help alert you of your surroundings to get you to your car safely. Anxiety can help you perform better. Have a big presentation at work? Anxiety can help ensure you prepare so you perform your best.
Anxiety is also a normal and appropriate response to stressful events. It only becomes a problem when we react to it in a way that is counte

Did you know.... We are all composed of stardust.
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."
Did you know.... The Origins of the Universe
The Universe did not exist indefinitely. It was conceived. All matter, energy, space, and even time exploded in a massive explosion known as the Big Bang 13.82 billion years ago. The explosion continued to expand, and out of the cooling debris formed galaxies - vast islands of stars, of which our Milky Way is one of an estimated two trillion. In a nutshell, this is the Big Bang theory. Whatever way you look at it, the concept that the Universe arose from nothing – that there was a day without a yesterday – is completely insane. But the data suggests otherwise. The obvious question is, what happened before the Big Bang? The unwillingness to confront this unpleasant subject is why most scientists had to be dragged
Anxiety Often Begins In Childhood
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.

Anxiety Disorders Increase Risk Of Health Complications
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.
Anxiety Can Cause Physical Symptoms
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.
Anxiety Can Cause Memory Problems
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.
Anxiety Can Cause Cold Hands And Feet
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.
Anxiety Can Cause Anger
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.
