We only have to look at ourselves to see how intelligent life might develop into something we wouldnt want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.

When something is made idiot proof, they will just make better idiots.

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code.

I wouldnt be here today if it were not for the NHS, I have received a large amount of high-quality treatment without which I would not have survived.

In fact, if one considers the possible constants and laws that could have emerged, the odds against a universe that produced life like ours are immense.

We've created life in our own image.

In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down.
