Jim Al-Khalili
In these lively and fascinating essays, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like. Since 2000, science has seen a surge in data and interest on several fronts related to ET (extraterrestrials); AI (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we'll ever make contact.
Included in this audiobook are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being acting out a virtual reality game?
For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

.. a nice potpourri of ideas & approaches towards a the topic of "ALIENS" ( and LIFE in general !!! ) One Chapter ( I think it is #14) just killed it for me. I couldn't believe what I read /heard and after some fact checking I am convinced more than ever that we are alone.Paradigm Shift towards "We Are Alone"

The big question is...where did this all come from, smart people back track things using evidence dug up along with some smart science but what was here before the Big Bang and what made the Big Bang happen!?!? Who or what made space and everything in it!?!?
Space...................lots of space in space

If you could sum up Aliens in three words, what would they be?
Intriguing, worrying, and frustrating. The first two are both meant in a good way. For an explanation of the last, see below.What did you like best about this story?
The realism w/ regard to the likelihood of alien civilizations.What does the narrators bring to the story that you wouldn’t experience if you just read the book?
The ability to consume the book while driving? For something like this, audiobook format is probably objectively worse.Was this a book you wanted to listen to all in one sitting?
No.Any additional comments?
A significant portion of Chapter 14 (Chapter 15 in the audible file) is devoted to arguing that eukaryotes/eukaryote-equivalents are likely quite rare because endosymbiosis has only occurred once (Mitochondria). After five minutes of building on that argument (during which I was getting angrier and angrier) the author of that chapter admits that it has actually occurred twice (the second time being Chloroplasts), which completely undermines the prior five minutes *and is still wrong.* Endosymbiosis of cyanobacteria, creating chloroplasts, has happened at least twice that we know of, and it may well have occurred more times than that.I guess I'm just frustrated they wasted so much time and space on a crappy argument for the lack of complex life on other planets, and that they oversold it so badly.
Very Interesting; Poorly Fact-Checked
