I just went to the film Skyline tonight. Another Aliens attack Earth film in the spirt of War of the worlds, Cloverfield, and Independance day. I must say it had me wondering, why would aliens wait till we are at the peak of our military-industrial civilization to attack?

A better time would have been prior to 1850 when we had no airplanes, missles, tanks or nukes. They could also wait until AFTER we exhaust the Earth's resources and our civilization collapses under its own weight. Why come now at the peak; unless they do it for sport and enjoy a challenge?

I could just see alien ships arriving some day and saying 'Hey we planted our flag on this planet 150 million years ago, its our property- get lost'. That's as likely of a possibility as aliens arriving 150 million years from now when they would only find humans if they examined the fossil record of the planet.

(Or there might not be any hostile aliens out there to worry about)

Won't the aliens develop fusion reactors and solar power, etc.? Then they will live happily ever after on their own planet.

If they ran out of resources, they might need to go invading other planets.

If they ran out of resources, they might need to go invading other planets.

But if they exhausted their resources, they would not be able to extend their empire.

This guy makes a good point on the near 0 possibilities of an Alien invasion, contradicting stephen hawking.

Cordial Deconstruction of Stephen Hawking? (Am I So Bold?)

Would you drive to Alaska to buy gasoline? Stephen Hawking seems to think you might if your local gas station ran out.

Here’s my take on the ID4/ hostile aliens thing:

(And here is where I dare to Cordially Deconstruct the position of someone who is much, much, much smarter than I am)

paraphrase form the book 'little green men, and blight lights'. creatures are not not trying to send us mssgs, not trying trying to save us, in fact not even observing us (flying for 100 thousand years to watch us do our mundane routines, that's worth it, right)?

There was a report I read decades ago giving physics evidence that nearly any alien species out there in the unverse will be anerobic life. It turns out that mathematically Oxygen is far more rare in our galaxy on average than it is in our local region. That mean xygen breathers outside off our small region will not be able to evolve because there is no oxygen excss able to build up atmospheres like ours. Most planets in our galaxy at least will be stuck in the anerobic condition like earth was before the cyano-bacteria evolved. Any oxygen released in other places will be taken up geologically because of the ratio of carbon to oxygen on worlds outside our region.

This was proposed as the answer to the Fermi Paradox and so far as I can tell never refuted. The reason we don’t see hundreds of radio signals out there is because our kind of life is exceedingly rare. How would anerobic life forms communicate? Their chemical energy basis is only about a tenth of that available for oxygen based life, so maybe they are talking all over the place and we jus don’t recognze their speech patterns because they are so slow compared to ours.

The so called aliens are subject to the same limitations as us, would perish traveling thousands of light years in zero G, if they had the tech to even begin such a journey. Stephen Hawking is stark raving mad.
