So, what exactly is going to happen to that Tesla that Elon Musk shot into space?
It's going to wander around the solar system, sure. But there are planets and gravity and stuff, so what are the odds of it eventually slamming into something?
Small, but not zero -- according to this fun analysis by a group of astrophysicists! They modeled the Telsa's current trajectory and estimated that there's a mid-to-low-single-digit chance that it hits Earth or Venus over the next million years:
The orbital evolution is initially dominated by close encounters with the Earth. The first close encounter with the Earth will occur in 2091. The repeated encounters lead to a random walk that eventually causes close encounters with other terrestrial planets and the Sun. Long-term integrations become highly sensitive to the initial conditions after several such close encounters. By running a large ensemble of simulations with slightly perturbed initial conditions, we estimate the probability of a collision with Earth and Venus over the next one million years to be 6% and 2.5%, respectively. We estimate the dynamical lifetime of the Tesla to be a few tens of millions of years.
Stephen Hawking’s final paper that he and his colleagues completed just days before his death has now been published. It’s titled “Black Hole Entropy and Soft Hair,” co-authored with Sasha Haco, Malcolm J. Perry, and Andrew Strominger, about the black hole information paradox. Here is the abstract: A set of infinitesimal VirasoroL⊗VirasoroR diffeomorphisms are presented […]

In normal life, you open the car door before getting into the car. Operation A happens before operation B. That’s the causal order of things. But a new quantum switch weirdly enables two operations to happen simultaneously. From Science News: The device, known as a quantum switch, works by putting particles of light through a […]
Speed reading isn’t just an innate skill possessed by a lucky few. Anyone can learn to speed read, and the benefits are endless. The brain can process more information than most people have time to soak up, but you can make that time now with the 2018 Award-Winning Speed Reading Bundle. The first half of […]
Sure, you could use the same old PowerPoint templates for your next business presentation. It’s not like you have bosses or investors to impress. Oh wait, you do? Time to augment that slideshow with Slideshop – the presentation tool that can individualize your pitch while saving you time. Compatible with PowerPoint, Keynote and Google Slides, […]
Multinational companies have used the no-nonsense methodologies of Six Sigma and Lean Six Sigma to oil a smooth-running operation for years. What is it? Six Sigma (and its offshoot, Lean Six Sigma) apply the principles of science to business, teaching managers to methodically target waste, maximize output and streamline the flow from producer to consumer.
