So you think you know your universe? We’ve got our own top 10 list on the most interesting facts about the Universe.
1. It was hot when it was young
The most widely accepted cosmological model is that of the Big Bang. This was proven since the discovery of the cosmic microwave background radiation or CMBR. Although, strictly speaking, no one knows exactly what ‘banged’, we know from extrapolation that the Universe was infinitely hot at birth, cooling down as it expanded.
In fact, even only within minutes of expansion, scientists predict its temperature to have been about a billion Kelvin. Moving backward to 1 second, it is said to have been at 10 billion Kelvin. For comparison, today’s universe is found to have an average temperature of only 2.725 Kelvin.
2. It will be cold when it grows old
Observations made especially on galaxies farthest from us show that the Universe is expanding at an accelerated rate. This, and data that show that the Universe is cooling allows us to believe that the most probable ending for our universe is that of a Big Freeze.
That is, it will be devoid of any usable heat (energy). It is due to this prediction that the Big Freeze is also known as the Heat Death.Accurate measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP) on the current geometry and density of the Universe favor such an ending.
3. The Universe spans a diameter of over 150 billion light years
Current estimates as with regards to the size of the Universe pegs it at a width of 150 billion light years. Although it may seem peculiarly inconsistent with the age of the Universe, which you’ll read about next, this value is easily understood once you consider the fact that the Universe is expanding at an accelerated rate.
4. The Universe is 13.7 billion years old
If you think that is amazing, perhaps equally remarkable is the fact that we know this to better than 1% precision. Credit goes to the WMAP team for gathering all the information needed to come up with this number. The information is based on measurements made on the CMBR.
Older methods which have contributed to confirming this value include measurements of the abundances of certain radioactive nuclei. Observations made on globular clusters, which contain the oldest stars, have also pointed to values close to this.
5. The Earth is not flat – but the Universe is
Based on Einstein’s Theory of General Relativity, there are three possible shapes that the Universe may take: open, closed, and flat. Once again, measurements by WMAP on the CMBR have revealed a monumental confirmation – the Universe is flat.
Combining this geometry and the idea of an invisible entity known as dark energy coincides with the widely accepted ultimate fate of our universe, which as stated earlier, is a Big Freeze.
6. Large Scale Structures of the Universe
Considering only the largest structures, the Universe is made up of filaments, voids, superclusters, and galaxy groups and clusters. By combining galaxy groups and clusters, we come up with superclusters. Some superclusters in turn form part of walls, which are also parts of filaments.
The vast empty spaces are known as voids. That the Universe is clumped together in certain parts and empty in others is consistent with measurements of the CMBR that show slight variations in temperature during its earliest stages of development.
7. A huge chunk of it is made up of things we can’t see
Different wavelengths in the electromagnetic spectrum such as those of radio waves, infrared, x-rays, and visible light have allowed us to peer into the cosmos and ‘see’ huge portions of it. Unfortunately, an even larger portion cannot be seen by any of these frequencies.
And yet, certain phenomena such as gravitational lensing, temperature distributions, orbital velocities and rotational speeds of galaxies, and all others that are evidence of a missing mass justify their probable existence. Specifically, these observations show that dark matter exists. Another invisible entity known as dark energy, is believed to be the reason why galaxies are speeding away at an accelerated rate.
8. There is no such thing as the Universe’s center
Nope. The earth is not the center of the Universe. It’s not even the center of the galaxy. And no again, our galaxy is not the entire universe, neither is it the center. Don’t hold your breath but the Universe has no center. Every galaxy is expanding away from one another.
9. Its members are in a hurry to be as far away from each other as possible
The members that we are talking about are the galaxies. As mentioned earlier, they are rushing away from each other at increasing rates. In fact, prior to the findings of most recently gathered data, it was believed that the Universe might end in a Big Rip. That is, everything, down to the atoms, would be ripped apart.
This idea stemmed from this observed accelerated rate of expansion. Scientists who supported this radically catastrophic ending believed that this kind of expansion would go on forever, and thus would force everything to be ripped apart.
10. To gain a deeper understanding of it, we need to study structures smaller than the atom
Ever since cosmologists started to trace events backward in time based on the Big Bang model, their views, which focused only on the very large, got smaller and smaller. They knew, that by extrapolating backward, they would be led into a universe that was very hot, very dense, very tiny, and governed by extremely high energies.
These conditions were definitely within the realm of particle physics, or the study of the very small. Hence, the most recent studies of both cosmology and particle physics saw an inevitable marriage between the two.
There you have it. Feel free to come up with a longer list of your own.

People sharing fitness routine can have mental issues
Be honest with me here: You have one or even multiple friends, who always post their gym activity to Facebook. Or maybe that person is you.
"Ran 15 miles before work! Yeah" can be motivating to read in the morning, or incredibly annoying, depending on how much you hate that painfully overused flexed-biceps-emoji.
Researchers from the Brunel University in London have conducted a study as to why so many people share every workout on social media. The results are unflattering, to say the least.
Addicted to attention and esteem
People who are always keen on documenting their gym activities (or every time you simply go for a good, old-fashioned run) tend to be narcissists. According to the researchers, the primary goal is to boast about how much time you invest in your looks. Apparently, these status updates also earn more Facebook likes than other kinds of posts.
"Narcissists more frequently updated about their achievements, which was motivated by their need for attention and validation from the Facebook community", the study concludes. The high number of likes doesn't necessarily mean everyone loves seeing those bragging posts, though.

10 amazing facts that will make you say WTF
How long does a human hair live for? What's the strongest muscle in the body? These questions and many other bizarre quandaries will be answered in this extra fascinating list of 40 amazing facts about the body you call your home!
1. The brain is more active at night than during the day. Scientists don't know yet why this is.
2. The higher your IQ, the more you supposedly dream.
3. Facial hair grows faster than any other hair on the body.
4. The nail on the middle finger grows faster than the other fingernails.
5. Fingernails grow nearly four times faster than toenails.
6. The lifespan of a human hair is 3 to 7 years on average.
7. The acid in your stomach is strong enough to dissolve zinc. It doesn't destroy the stomach because the stomach walls constantly renews itself.
8. Women's hearts beat faster than men's.
9. Women blink twice as many times as men do.
10. Women are born better smellers than men and remain better smellers over life.
11. Men burn fat faster than women by a rate of about 50 calories a day.
12. Men get hiccups more often than women.
13. A man has approximately 6.8 liters of blood in the body while women have approximately 5 liters.
14. The largest cell in the body is the female egg and the smallest is the male sperm.
15. During your lifetime, you will produce enough saliva to fill two swimming pools.
16. Babies are born with blue eyes more than any other color. The melanin in their eyes needs time to be fully deposited or to be darkened by ultraviolet light to reveal the baby's true eye color.
17. Men have erections every hour to hour and a half during sleep. This is because the combination of blood circulation and testosterone production can cause erections during sleep and are a necessary part of REM sleep.
18. After eating too much, your hearing is less sharp.

Effects of drinking coca cola
Sugary drinks are considered a major contributor to health conditions such as obesity, type 2 diabetes and tooth decay. But have you ever wondered exactly what these beverages do to your body after consumption? One researcher has created an infographic that explains what happens to the body within an hour of drinking a can of Coca-Cola.
A glass of cola
A 12-ounce serving of Coca-cola contains approximately 10 teaspoons of sugar.
According to the Centers for Disease Control and Prevention (CDC), around half of the US population drink sugary beverages on any given day, with consumption of these drinks highest among teenagers and young adults.
There are approximately 10 teaspoons of added sugar in a single can of cola. The World Health Organization (WHO) recommend consuming no more than 6 teaspoons of added sugar daily, meaning drinking just one serving of cola a day could take us well above these guidelines.
As such, it is no surprise that sugary drink consumption is associated with an array of health conditions. According to the Harvard School of Public Health, people who drink 1-2 cans of sugary beverages daily are 26% more likely to develop type 2 diabetes, and last month, Medical News Today reported on a study claiming 184,000 global deaths each year are down to sugary drink consumption.
Now, an infographic created by British pharmacist Niraj Naik - based on research by health writer Wade Meredith - shows the damage a 330 ml can of Coca-Cola can do to the body within 1 hour of consumption.
