“Our existence in this place, this microscopic corner of the cosmos, is fleeting. With utter disregard for our wants and needs, nature plays out its grand acts on scales of space and time that are truly hard to grasp. Perhaps all we can look to for real solace is our endless capacity to ask questions and seek answers about the place we find ourselves in.”
Caleb Scharf

“We are accelerating and extending our minds through our computers and algorithms, through our medical prowess and our accumulated knowledge. These minds of ours are the most precious things; we need to cherish all seven-plus billion of them. Walking this rocky globe somewhere today may be a human who will take us to the next level of insight. This person could be anywhere-from Africa to Asia, Oceania to Europe, or in the Americas. This person could even be you. And that journey will be as extraordinary as this one.”
Caleb Scharf, The Zoomable Universe: An Epic Tour Through Cosmic Scale, from Almost Everything to Nearly Nothing

“As a gas of normal matter pulls together-or, rather, falls together-it transforms gravitational potential energy into thermal energy. In other words, it heats up. That sets in motion a competition between gravity workimg to condense matter and thermal-energy pressure spreading matter apart. In the right circumstances, though, if the matter can cool off fast enough, gravity can pull it into very dense concentrations indeed.”
