My creepy time travel experience

timetravelI just got this creepy message from Goodreads.com in my Facebook feed:

“Goodreads added something in the past to your timeline.”

How sinister is that? How can something have been added just now but in the past? Continue reading

Science, philosophy, and the Mountain of Ignorance

mountainofignoranceThere’s been a lot of debate online recently (like here and here) about whether philosophy is a waste of time. Here’s my metaphor for thinking about this question.

Imagine that ignorance is represented by a mountain. The mountain is big and in plain view of everyone. Even small children can see it clearly, and love to ask questions about it that their parents can’t answer. You know the kinds of questions I mean. Continue reading

One billion good reasons to be afraid

asteroids65 million years ago an enormous lump of rock – a comet or asteroid over a mile in diameter – crashed into the Earth at enormous speed – perhaps 200 times the speed of sound – leaving a crater 193 km wide and 48 km deep.

Think about that for a moment. Continue reading

Stepping stones to Transhumanism

googleglassThe Consumer Electronics Show (CES2014) currently taking place in Las Vegas is packed full of smart glasses, like Google Glass.

Wearable tech is poised to transform the way we interact with technology. With a pair of smart glasses, you can begin to feel like superman, taking photos and recording videos of anything you see, and with the almost telepathic ability to interact directly with the internet and with your own automated personal assistant.

Don’t doubt that this will happen, just so long as the cost is affordable and the tech works in a convenient way. After all, just a few years ago, how many people would have imagined that we would be carrying smartphones everywhere and that email, Facebook and other social media would be just as important as face to face communication?

Smart glasses are just the latest in a long history of creeping augmentation of our abilities by technology. Observers of technology call this transition “Transhumanism” and predict an inevitable and exponential increase in how this impacts on our lives. Continue reading

A for Andromeda

andromedagalaxyThe endless reaches of space are almost entirely empty, so you might imagine that collisions between stars are extremely rare events. However, because of gravity, matter tends to clump together (which is why space is mostly empty). As a result, collisions between stars and even galaxies happen surprisingly often.

And I have some bad news for you. The Andromeda galaxy, containing 1 trillion stars, is on a collision course with our own galaxy, the Milky Way, and is approaching at a speed of 200 miles per second. Continue reading

Climate change conundrum

The end of the world is nigh (again)

mushroomcloudWhen I was growing up in the 1970s, my friends and I used to play a card game called Inter-Continental Ballistic Missiles (it was a variation of Snap.) In those Cold War days nearly everybody believed that the world would be destroyed in a nuclear attack. Continue reading
