“Human beings are strong because we have the ability to change ourselves.” Saitama, One Punch Man The idea of stopping a meteor headed towards our planet with nothing but a superpowered human being sounds like a physical impossibility. But if you had a powerful enough, strong enough, fast enough human, it could be done, so long…

“Dimension regulated the general scale of the work, so that the parts may all tell and be effective.” -Vitruvius In a four-dimensional Universe (3 space and 1 time), it’s easy to get lost. If you take a random walk, the chances of you coming back to your original starting point in a finite number of…

“Even though the future seems far away, it is actually beginning right now.” -Mattie Stepanek After another tremendous week here at Starts With A Bang, including one where I recorded a new podcast (look for it later this week on SoundCloud), it’s time to take a look back and review all that we’ve been through. From last…

“‘Star Trek’ says that it has not all happened, it has not all been discovered, that tomorrow can be as challenging and adventurous as any time man has ever lived.” –Gene Roddenberry Today marks the 50th anniversary of the premiere of Star Trek, our first science fiction adventure that promised a positive view of the future,…

“For me the best answer is not in words but in measurements.” -Elena Aprile If you want to find dark matter directly, your best hope is to gather a tremendous number of nucleons for it to interact with, wait an incredibly long period of time, and devise a device surrounding it capable of detecting even…

“Go, then. There are other worlds than these.” -Stephen King We think of the Universe as all there ever is, was or will be. But, in fact, there’s a limit to the most distant galaxies, stars, matter and radiation we can see. The hot Big Bang occurred a finite amount of time ago, and hence…

“If you’re puzzled by what dark energy is, you’re in good company.” -Saul Perlmutter The accelerated expansion of our Universe was one of the biggest surprise discoveries of all-time, and something that still lacks a good physical explanation. While many models of dark energy exist, it remains a completely phenomenological study: everything appears consistent with…

“I found I could say things with color and shapes that I couldn’t say any other way — things I had no words for.” –Georgia O’Keeffe The Standard Model is great at describing all the known particles we’ve ever observed and how they interact, but there are a number of important hints that it isn’t…

“It is possible to commit no mistakes and still lose. That is not a weakness. That is life.” –Jean-Luc Picard The laws of electromagnetism could have been incredibly different. Our Universe has two types of electric charge (positive and negative) and could have had two types of magnetic pole (north and south), but only the…

“Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?” -Stephen Hawking One of the greatest discoveries of the 20th centuries was not only that there were just four fundamental…
