Radio and television broadcasting may be only a brief passing phase in our technological development. When we imagine alien civilizations broadcasting signals with radio telescopes, are we any different from earlier generations who imagined riding cannon shells to the moon? Civilizations even slightly more advanced than ours may have already moved on to some other mode of communication, one that we have yet to discover or even imagine. Their messages could be swirling all around us at this very moment, but we lack the means to perceive them just as all of our ancestors, up to a little more than a century ago, would have been oblivious to the most urgent radio signal from another world.
But there’s another more troubling possibility: Civilizations, like other living things, may only live so long before perishing due to natural causes, or violence, or self-inflicted wounds. Whether or not we ever make contact with intelligent alien life may depend on a critical question: What is the life expectancy of a civilization?

The most fascinating aspect of this book is that it was originally written by I.S. Shklovskii in Russian, re-translated into English, whereby Carl adds his scientific “two-cents”, expanding on subjects and explaining further in a way only Carl, himself, can. For instance, the last paragraph in Chapter 31: Interstellar contact by automatic probe vehicles:
“At this point in the Russian edition of the present work, Shklovskii expresses his belief that civilizations are not inevitably doomed to self-destruction, despite his description of contemporary Western literature as filled with details of atomic holocaust. He expresses his belief that as long as capitalism exists on Earth, a violent end to intelligent life on the planet is probable. There is reason to assume, he asserts, that future peaceful societies will be constructed on the basis of Communism. I am able to imagine alternative scenarios for the future. No one today lives in a society which closely resembles Adam Smith capitalism or Karl Marx communism. The political dichotomies of the twentieth century may seem to our remote descendants no more exhaustive of the range of possibilities for the entire future of mankind than do, for us, the alternatives of the European religious wars of the sixteenth and seventeenth centuries. As Shklovskii says, the forces of peace in the world are great. Mankind is not likely to destroy itself. There is too much left to do.”
Roads and paths pervade our literature, poetry, artwork, linguistic expressions and music. Even photographers can’t keep their eyes (and lenses) off of a beautiful road or path, which is why we collected this list of 28 amazing photos of paths.
Paths like these have a powerful grip on the human imagination – they can bring adventure, promise and change or solitude, peace and calm. There’s nothing like a walk down a beautiful path to clear your head – or to fill it with ideas!
I’ll leave you with an excellent quote from J. R. R. Tolkien’s works while you enjoy these images; “It’s a dangerous business, Frodo, going out your door. You step onto the road, and if you don’t keep your feet, there’s no knowing where you might be swept off to.“
Guest contributor Peter Miles looks at LGBT+ representation and its reception.
I recently wrote an article for DWTV about the Jenny/Vastra kiss and LGBT+ representation in Doctor Who and other forms of media. I’ll be honest, considering that the fans on there are a different type of fans to the ones on tumblr, in some sense it’s not entirely true as to what I’d actually write, however the responses in the comments did shift in the direction I was concerned they would anyway i.e. people trying to defend their slightly homophobic views as not homophobic.
Despite that, I think my message came through pretty clearly to the majority of others and I’d be interested to know what everyone else thinks
