Unlike entering any normal space, entering Blur is like stepping into a habitable medium.

It provides a physical support structure for the trees, and it creates physical spaces, habitable spaces inside of the sand dunes.

So, we have a way of turning sand into sandstone, and then creating these habitable spaces inside of the desert dunes.

Galaxies form, and generations of stars form in those galaxies, and around one star, at least one star, is a habitable planet.

We see the result, the traces, if you like, of the Bacillus pasteurii being harnessed to sculpt the desert into these habitable environments.

Because of the increase in speed, and because of the vast amount of habitable real estate in the cosmos, I figure we're going to pick up a signal within two dozen years.

And we can find those that we would call habitable, meaning that they have similar conditions to the conditions that we experience here on Earth and where a lot of complex chemistry can happen.

Or, who made the earth habitable, and made rivers flow through it, and set mountains on it, and placed a partition between the two seas? Is there another god with God? But most of them do not know.

But, if I had something like a TED wish, it would be to actually get it built, to start building this habitable wall, this very, very long, but very narrow city in the desert, built into the dunescape itself.

You know, culture was born of the imagination, and the imagination the imagination as we know it came into being when our species descended from our progenitor, Homo erectus, and, infused with consciousness, began a journey that would carry it to every corner of the habitable world.

Who then made the earth a habitable place, and made the rivers (flow) in its valleys and dales, and placed upon it firm stabilisers, and kept a barrier between two bodies of water? Is there any other god along with God? In reality most of them do not know.

And much of this vast universe, much more may be habitable than we once thought, as we study extremophiles on Earth organisms that can live in conditions totally inhospitable for us, in the hot, high pressure thermal vents at the bottom of the ocean, frozen in ice, in boiling battery acid, in the cooling waters of nuclear reactors.

So when we want to learn whether a planet is habitable, whether it might be amenable to life, we want to know not only how much total light it receives and how warm it is, but we want to know about its space weather this high energy radiation, the UV and the X rays that are created by its star and that bathe it in this bath of high energy radiation.

Well, Don Brownlee, my friend, and I finally got to the point where we got tired of turning on the TV and seeing the spaceships and seeing the aliens every night, and tried to write a counter argument to it, and put out what does it really take for an Earth to be habitable, for a planet to be an Earth, to have a place where you could probably get not just life, but complexity, which requires a huge amount of evolution, and therefore constancy of conditions.
