“The world is the great gymnasium where we come to make ourselves strong.” -Swami Vivekananda But what does it truly mean to be strong? We have four fundamental forces in the Universe: the strong, electromagnetic, weak and gravitational forces. You might think that, by virtue of its name, the strong force is the strongest one.…

“That’s all regular matter, just five percent. A quarter is “dark matter,” which is invisible and detectable only by gravitational pull, and a whopping 70 percent of the universe is made up of “dark energy,” described as a cosmic antigravity, as yet totally unknowable. It’s basically all mystery out there – all of it, with…

“Quintessence is a dynamic, time-evolving, and spatially dependent form of energy with negative pressure sufficient to drive the accelerating expansion […] Whereas the cosmological constant is a very specific form of energy.” -Robert Caldwell, inventor of the Big Rip scenario Our Universe began with a period of cosmic inflation: where energy intrinsic to space itself…

“If you take everything we know… it only adds up to 5% of the Universe.” -Katie Freese One of the greatest advances of the 20th century was the discovery of the vast nature of the cosmos: that it was filled with billions of galaxies, each containing billions of stars, and that it extended in all…

“Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my luck and instead will spend my life trying to find flaws in this understanding – such is the role of a scientist.” -Brian Schmidt One of the biggest surprises in our understanding of the Universe…

“Gamow was fantastic in his ideas. He was right, he was wrong. More often wrong than right. Always interesting; … and when his idea was not wrong it was not only right, it was new.” -Edward Teller Considering what we know about our Universe today, it’s hard to believe that just a century ago, Einstein’s…

“There are still so many questions to answer. When you look at any part of the universe, you have to feel humbled.” -Saul Perlmutter Discovered in 1998 from the observation of distant supernovae, dark energy determines the eventual fate of the Universe, leading to a “Big Freeze” scenario, where all the galaxies, groups and clusters that…

“What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as earth and ice, water, fire and air, a quintessence, pure spirit, resolving into no constituents.” –Jay Griffiths When you think about the frontiers of scientific knowledge — on the border between what’s known and what’s unknown —…

“First, you should check out my house. It’s, like, kinda lame, but way less lame than, like, your house.” –Lumpy Space Princess, Adventure Time When you visualize our Universe today, you probably think about the great clumps of matter — planets, stars, galaxies and clusters — separated by huge distances. But on the largest of…

“There is no end to education. It is not that you read a book, pass an examination, and finish with education. The whole of life, from the moment you are born to the moment you die, is a process of learning.” –Jiddu Krishnamurti If you want to learn something — whether it’s abstract or concrete, solving…
