What's the deal with these strange arctic holes that not even NASA can explain?
Almost nobody noticed this, but back in December a chunk of space rock slammed into the Earth's atmosphere at 32km/sec over the Bering sea. The aerodynamic forces tore it apart and it released energy equivalent to a 170 kiloton weapon.
And almost nobody noticed.
We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.
This is a picture of the future as painted by modern science - a picture that will surely evolve over time as we dig for more clues to how our story will unfold. Much of the science is very recent - and new puzzle pieces are still waiting to be found.
To me, this overhead view of time gives a profound perspective - that we are living inside the hot flash of the Big Bang, the perfect moment to soak in the sights and sounds of a universe in its glory days, before it all fades away. Although the end will eventually come, we have a practical infinity of time to play with if we play our cards right. The future may look bleak, but we have enormous potential as a species.

Black holes grow by accreting matter under gravity; so surely they should be able to accrete dark matter? So then is there loads of dark matter trapped inside black holes?
Turns out it's a bit more complicated than that because of what we know of how dark matter behaves - which isn't a lot! - but it's enough.
Is math real or simply something made up by mathematicians? You can’t physically touch a number yet using numbers we’re able to build skyscrapers and launch rockets into space. Mathematician Kelsey Houston-Edwards explains this perplexing dilemma and discusses the different viewpoints that philosophers and mathematicians have regarding the realism of mathematics.
