Neil deGrasse Tyson
“We are stardust brought to life, then empowered by the universe to figure itself out—and we have only just begun.”
Neil deGrasse Tyson, Astrophysics for People in a Hurry

Neil deGrasse Tyson
“In 2002, having spent more than three years in one residence for the first time in my life, I got called for jury duty. I show up on time, ready to serve. When we get to the voir dire, the lawyer says to me, “I see you’re an astrophysicist. What’s that?” I answer, “Astrophysics is the laws of physics, applied to the universe—the Big Bang, black holes, that sort of thing.” Then he asks, “What do you teach at Princeton?” and I say, “I teach a class on the evaluation of evidence and the relative unreliability of eyewitness testimony.” Five minutes later, I’m on the street.

A few years later, jury duty again. The judge states that the defendant is charged with possession of 1,700 milligrams of cocaine. It was found on his body, he was arrested, and he is now on trial. This time, after the Q&A is over, the judge asks us whether there are any questions we’d like to ask the court, and I say, “Yes, Your Honor. Why did you say he was in possession of 1,700 milligrams of cocaine? That equals 1.7 grams. The ‘thousand’ cancels with the ‘milli-’ and you get 1.7 grams, which is less than the weight of a dime.” Again I’m out on the street.”

Neil deGrasse Tyson
“People who believe they are ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the universe.”
Neil deGrasse Tyson, Astrophysics for People in a Hurry

Neil deGrasse Tyson
“The gravitational waves of the first detection were generated by a collision of black holes in a galaxy 1.3 billion light-years away, and at a time when Earth was teeming with simple, single-celled organisms. While the ripple moved through space in all directions, Earth would, after another 800 million years, evolve complex life, including flowers and dinosaurs and flying creatures, as well as a branch of vertebrates called mammals. Among the mammals, a sub-branch would evolve frontal lobes and complex thought to accompany them. We call them primates. A single branch of these primates would develop a genetic mutation that allowed speech, and that branch—Homo Sapiens—would invent agriculture and civilization and philosophy and art and science. All in the last ten thousand years. Ultimately, one of its twentieth-century scientists would invent relativity out of his head, and predict the existence of gravitational waves. A century later, technology capable of seeing these waves would finally catch up with the prediction, just days before that gravity wave, which had been traveling for 1.3 billion years, washed over Earth and was detected.

Yes, Einstein was a badass.”

Neil deGrasse Tyson
“For reasons I have yet to understand, many people don’t like chemicals, which might explain the perennial movement to rid foods of them. <...> Personally, I am quite comfortable with chemicals, anywhere in the universe. My favorite stars, as well as my best friends, are all made of them.”

Ashim Shanker
“The arrow of time obscures memory of both past and future circumstance with innumerable fallacies, the least trivial of which is perception.”

Albert Einstein
“Einstein on time travel:
"People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion.”
Albert Einstein

Murray Gell-Mann
“During the period of recollapse, the universe will not be running through its expansion in reverse. The notion that expansion and contraction would be symmetrical with each other is what Stephen Hawking calss his "greatest mistake”
Murray Gell-Mann, The Quark and the Jaguar: Adventures in the Simple and the Complex

“We are a species poised between an awareness of our ultimate insignificance and an ability to reach far beyond our mundane lives, into the void, to solve the most fundamental mysteries of the cosmos.”
Katie Mack, The End of Everything

“Space Exploration Ethics 101

If we can colonize Mars, we can heal the Earth. But that's not the point here. The point is, we gotta explore space just like we gotta explore anything unknown - but we must do so as humble scientists, not as steroid-pumped, illegitimate offspring of musky retards like Columbus.

We gotta explore space just like we explore the Arctic. Humankind has several outposts in the Arctic, dedicated solely to research - our endeavors into other planets oughta be exactly like that. Otherwise, what starts out as space exploration will soon turn into space imperialism, and will do to other planets what white terrorists have been doing to the indegenous people on earth for ages.

Therefore, focus on space exploration, not on space colonization. Let me put this into perspective. NASA, ISRO, CNSA, ESA, KARI, JAXA (and more) - these represent the real democratic aspirations of humankind's endeavors of curiosity into space, whereas SpaceX, Blue Origin, Virgin Galactic these are the new-age posterboys of space imperialism.

All I say is this, O Brave Explorers of Space - your mission is to explore the universe to facilitate human welfare, not to be some retarded billionaire's backboneless underwear. Beware, I repeat - space exploration doesn't turn into space imperialism!”

“There appears to be no end to the evidence of fine-tuning and design coming from scientific discovery.”
Hugh Ross, Designed to the Core

Hugh Ross
“If a purposeful Tuner exists, it makes sense that the deeper our search into the features of the cosmos, the more evidence of fine-tuning this search will reveal. If no purposeful Tuner exists, then a deeper search will reveal less and less specificity and intentionality. A fine-tuner's attributes and purposes will become either increasingly clear or increasingly vague.”
Hugh Ross, Designed to the Core

Hugh Ross
“My hope is that evidence for the exquisite fine-tuning observed at all astronomical levels, from the farthest reaches of the cosmos to the ground beneath our feet, arouses a profound sense of awe and wonder. My greater hope is that this awe and wonder will inspire readers to ponder the deep questions raised by a close-up glimpse of nature's unfolding story.”
Hugh Ross, Designed to the Core

Hugh Ross
“More than 140 different 'exterior' features of the universe, including the values of the constants that govern the laws of physics, must fit within narrowly specified ranges. This reality reasonably points to a Source with the capacity for intentionality, for deliberate, purposeful design and implementation—in other words, a Creator who transcends the well-crafted cosmos.”
Hugh Ross, Designed to the Core

Hugh Ross
“The history and features of the solar system's asteroid-comet belts, along with the gravitational influences of the Moon's mass and early orbital proximity, ensured that Earth would receive sufficient impact events, especially before animals appeared, to salt Earth's crust with rich ore deposits. These ores played a crucial role in the early launch of metallurgy and, more recently, in the development of global, high-technology civilization. On the other hand, major impact events during the human era have been so infrequent as to pose no risk to humanity's survival nor to global civilization.”
Hugh Ross, Designed to the Core

Hugh Ross
“Physical life is not fluid. It will not and cannot adjust to any old universe. The fine-tuning that astronomers observe indicates that even very slight alterations to the universe's characteristics would rule out the possible existence of physical life.”
Hugh Ross, Designed to the Core

Hugh Ross
“Just as the interior structure of our supercluster of galaxies, our galaxy cluster, our galaxy, our local galactic neighborhood, our star, our system of planets, asteroids, and comets, and our Moon differ from the normal pattern in precise ways that favor the possibility of advanced life on Earth, so, too, does Earth's core.”
Hugh Ross, Designed to the Core

Hugh Ross
“The 8% level is the minimum required for the existence of large-bodied animals that lack digestive tracts and internal organs (the Avalon animals, e.g. sponges and jellyfish). The 10% level is the minimum required for animals with complex internal organs (the Cambrian animals). One of the great marvels of life history is that the Avalon and Cambrian animals representing several Avalon phyla and 30+ Cambrian phyla appeared in what may be considered a geologic 'instant' after each of the oxygen levels was attained.”
Hugh Ross, Designed to the Core

Hugh Ross
“Like the Great Oxidation Event, the Great Unconformity injected an enormous quantity of oxygen into the atmosphere through a massive and efficient subduction of organic carbon into Earth's mantle. When this event occurred, the oxygen quantity in Earth's atmosphere jumped from 1% or less up to 8%. Just before the time of the Cambrian explosion 543 million years ago, another major continental erosion event coupled with oceanic sediment subduction led to a jump in the atmosphere oxygen level from 8 to 10%.”
Hugh Ross, Designed to the Core

Hugh Ross
“[The features of Earth's mantle], among others, appear so intricate and specific that Earth may well be the only rocky planet on which plate tectonic activity, at a survivable level for life, has been operating for an extended period, much less approaching 4 billion years.”
Hugh Ross, Designed to the Core

Hugh Ross
“Neptune's complex migration history, known as the 'jumping Neptune' altered the Kuiper Belt's properties in the ways, all of which have a bearing on the possibility for advanced life and civilization on Earth.”

Hugh Ross
“All the scientists were upstaged at least 2,500 years earlier by Job, Moses, David, Isaiah, Jeremiah, and other Bible authors. The Bible’s prophets and apostles stated explicitly and repeatedly the two most fundamental properties of the big bang, a transcendent cosmic beginning a finite time ago and a universe undergoing a general expansion.”

“If you meet your anti-self, do not shake hands!, you would both vanish in a great flash of light.”
Abdul Rashid Khan, Astrophysics & the Holy Quran

“It is He Who made the Sun self-luminous and Moon radiant (reflecting the Sunlight), and measured for it stages, that you might know the number of years and (keep) the account."
- The Holy Qur'an (Surah Yunus, Ch. 10, Verse 5)”
Abdul Rashid Khan, Astrophysics & the Holy Quran

“وَهُوَ ٱلَّذِى خَلَقَ ٱلَّيْلَ وَٱلنَّهَارَ وَٱلشَّمْسَ وَٱلْقَمَرَ ۖ كُلٌّۭ فِى فَلَكٍۢ يَسْبَحُونَ

"It is He Who created the Night and the Day, and the Sun and the Moon: All (the celestial bodies) swim along, each in its own rounded course (elliptical path)."
- The Holy Quran (Sura Ambiyaa, Ch. 21, Verse 33)”
