Dear Ben Carson: an open letter (Synopsis)

“In science it often happens that scientists say, ‘You know that’s a really good argument; my position is mistaken,’ and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn’t happen as often as it should, because scientists are human and change…

“I was strongly encouraged by a science teacher who took an interest in me and presented me with a key to the laboratory to allow me to work whenever I wanted.” -Frederick Reines, discoverer of the first neutrino That kind of education is irreplaceable, and at Starts With A Bang we do our best to bring the…

“When you see how fragile and delicate life can be, all else fades into the background.” –Jenna Morasca The hot Big Bang — proposed seventy years ago — is a tremendous success story. Predicated on the assumption that the Universe was hotter, denser, more uniform and expanding faster in the past, it’s allowed us to…

When it comes to the Universe, physicists say things like: it originated in a Big Bang, it’s isotropic (or the same in all directions), and it’s homogeneous (the same everywhere), save for the effects of cosmic evolution. In every direction we look, we see galaxies expanding away from us, with the expansion rate increasing the…

“The slow philosophy is not about doing everything in tortoise mode. It’s less about the speed and more about investing the right amount of time and attention in the problem so you solve it.” –Carl Honore If you wanted to know how fast you were moving through space, you’d need to measure it all: the…

“The total number of people who understand relativistic time, even after eighty years since the advent of special relativity, is still much smaller than the number of people who believe in horoscopes.” –Yuval Ne’eman It’s been 13.8 billion years since the Big Bang for us, and when we look out at a distant object in…

“Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang.” –Alan Guth If we trace the evolution of our Universe back in time, we can arrive at a time before there were organic molecules, rocky planets,…

“The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to -271.3°C, not much good for defrosting the pizza, let alone cooking it.” –Stephen Hawking Imagine you traveled out into empty space. Away from any and all…

“It’s hard to build models of inflation that don’t lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a]…

“Were the succession of stars endless, then the background of the sky would present us a uniform luminosity, like that displayed by the Galaxy-since there could be absolutely no point, in all that background, at which would not exist a star.” -Edgar Allan Poe The master of the macabre, little known to most, was actually…
