Amazing. A simple idea, but the execution of it (the music and image choices) make it brilliant. Life… is amazing.

Around the World in 90 Minutes

What is it like to circle the Earth? Every 90 minutes, astronauts aboard the International Space Station experience just that. Recently, crew members took a series of light-sensitive videos looking down at night that have been digitally fused to produce the above time-lapse video.

Many wonders of the land and sky are visible in the eighteen sequences, including red aurora above green aurora, lights from many major cities, and stars in the background.

Looming at the top of the frame is usually part of the space station itself, sometimes seen re-orienting solar panels. Please help create a useful companion guide for this moving video by identifying landmarks, cities, countries, weather phenomena, and even background constellations that appear.

Fundamentals of The Multiverse

Images: Conceptual renderings of what Multiverses might look like

Andrei Linde at Stanford has brought forward the cosmological model of a multiverse, which he calls the “self-reproducing inflationary universe.” The theory is based on Alan Guth’s inflation model, and it includes multiple universes woven together in some kind of spacetime foam. Each universe exists in a closed volume of space and time. Linde’s model, based on advanced principles of quantum physics, defies easy visualisation. Quite simplified, it suggests quantum fluctuations in the universe’s inflationary expansion period to have a wavelike character. Linde theorises that these waves can “freeze” atop one another, thus magnifying their effect.

The stacked-up quantum waves can in turn create such intense disruptions in scalar fields -the underlying fields that determine the behaviour of elementary particles- that they exceed a critical mass and start procreating new inflationary domains. The multiverse, Linde contends, is like a growing fractal, sprouting inflationary domains, with each domain spreading and cooling into a new universe.

If Linde is correct, our universe is just one of the sprouts. The theory neatly straddles two ancient ideas about the universe: that it had a definite beginning, and that it had existed forever. In Linde’s view, each particular part of the multiverse, including our part, began from a singularity somewhere in the past, but that singularity was just one of an endless series that was spawned before it and will continue after it.
