“In 5 billion years, the expansion of the universe will have progressed...” — Lawrence M. Krauss Quote

“In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.”

“Empirical explorations ultimately change our understanding of which questions are important and fruitful and which are not.”

“It never ceases to amaze me that every second of every day, more than 6,000 billion neutrinos coming from nuclear reactions inside the sun whiz through my body, almost all of which will travel right through the earth without interruption.”

“If I knew what the next big thing was, I'd be doing it now.”

“Scientists don't read theology; they don't read philosophy. It doesn't make any difference to what they're doing - for better or worse, it may not be a value judgment, but it's true.”

“The experimenters computed an “intuition index” to measure accuracy. They found that putting the participants in a good mood before the test by having them think happy thoughts more than doubled accuracy.”

“A man ceases to be a beginner in any given science and becomes a master in that science when he has learned that he is going to be a beginner all his life.”

“Wesley went everywhere with me from then on. I even wrapped him in baby blankets and held him in my arms while grocery shopping, to keep him warm during the first cold winter. Occasionally someone would ask to see "the baby," and when I opened the blanket, would leap back shrieking, "What is that?! A dinosaur?" Apparently, the world is full of educated adults with mortgages and stock portfolios who think people are walking around grocery stores with dinosaurs in their arms.”

“When in doubt, C-4.”

“There are big questions science doesn't answer, such as why is there something rather than nothing? There can't be a scientific answer to that because it's the answer that precedes science.”
