When Stars Collide, Hyperloop Pods, Propellors and Quantum Catapults

Apparently, half the missing matter in the universe has been found.

I breath a sigh of relief, as I'm sure we all do.

Personally, the idea of dark matter and black holes gives me a sense of deep dread.

All that nothingness...(shivers)

One hundred and thirty million years ago, when dinosaurs roamed the Earth, two neutron stars collided.

In August, the signals from that event reached Earth, and became the first ever visual and gravitational record of such a cosmic cataclysm.

The visual and gravitational records arrived within 17 seconds of each other, which is pretty damn good for a journey spanning aeons* of time...

The image below looks underwhelming, but don't forget that you're looking at an event that took place long before we existed...

Personally, I'm still reeling with the simple fact that telescopes are time machines...

What we need is a quantum catapult, enabling us to cross the vast divide of space and time.

I'm working on it, but I need more elastic for the catapult.

It's a minor inconvenience - I'm sure Elon Musk could sort it out - speaking of whom, in a recent discussion of his hopes to use rockets as glorified 'airliners' on Mars, he displayed a masterful use of terms like 'rapid unscheduled disassembly' (rocket explodes) , and ' ...getting somewhere in thirty minutes by rocket...will be negatively affected if ...' you might die', is on the ticket.'

Fear not, though, as current tests for his (Earthbased)  hyperloop system are exceeding their own speed records, and it won't be long before intercity journey times are vastly reduced.

Google have expanded their maps to include places in our solar system: enjoy, but please don't confuse them with your own GPS...

'Propellor' imaged by Cassini    NASA

Remaining with our own corner of the cosmos, I found this article interesting, as it ponders a few discoveries of the belated (do we use this term for a spacecraft? ) Cassini, particularly the interesting 'propellors' created by moonlets in Saturns rings.

A world with moons named from figures of Greek mythos , including Janus, Pandora, Atlas, Dione and Prometheus is always worth revisiting, although my personal favourite is the little oddity known as Pan...

35km wide Pan...

Don't forget there is a little time left ( closing November 1,2017 )  to include your name on the Insight flight to Mars - get your boarding pass here

Not sure if I got a wing seat, knowing my luck, I'm probably in baggage...


...but I'll  see you there
