“Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen.” -Richard Feynman If you were to send a space probe to a distant…

“Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.” -Samuel Ullman When it comes to the Universe, there are some dead giveaways as to what its age is. Its elemental composition changes, the types…

“The fact that gravitational damping is measured at all is a strong indication that the propagation speed of gravity is not infinite.  If the calculational framework of general relativity is accepted, the damping can be used to calculate the speed, and the actual measurement confirms that the speed of gravity is equal to the speed…

“This event marks the culmination of many years of hard work on behalf of all involved.” -Jane Bachynski If you want to take an ideal image of the Universe, you need to not only minimize your light pollution, cloud cover and build the largest-aperture telescope you can, you also need to take away as much…

“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.…

“The phenomena of nature, especially those that fall under the inspection of the astronomer, are to be viewed, not only with the usual attention to facts as they occur, but with the eye of reason and experience.” -William Herschel We typically think of Saturn as our Solar System’s ringed world, thanks to its huge, glorious…

“I left Earth three times and found no other place to go. Please take care of Spaceship Earth.” -Wally Schirra We’ve made it through another amazing week here at Starts With A Bang, and what many of you might not realize is that there was a fabulous new release thanks to the support of everyone on…

“Yes, now there is this technological path. But it’s just starting.” -Mae Jemison Earlier this month, Yuri Milner and Stephen Hawking teamed up to announce the Breakthrough Starshot, a $100 million investment in technology that would build a laser array to propel a thin, light “laser sail” spacecraft to approximately 20% the speed of light.…

“We are not learning to view ourselves as an advanced, evolving civilization. That is what we really must learn to do, in due course, if we were to survive. All of that will take place, in due course, and we will be able to explore solar system. We will be able to go beyond it,…

“Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which things happen.” -Alan Guth If you go back in time, earlier and earlier, things get hotter, denser and more energetic. But there’s a limit to how far back you can go, and that…
