If we can't have "close encounters" with out fellow earth creatures, some quite intelligent, how will we ever relate to space aliens when and if we meet them? Everybody knows about successful attempts to teach sign language to our primate cousins, and unsuccessful attempts to communicate with dolphins. But what about large-brained cephalopods' intricate communications with one another through changing, glowing colors? We know that these creatures are smart and curious, and their DNA corresponds remarkably with ours. I think communicating with them would probably be easier than communicating with space aliens which, if they exist, evolved or were created entirely separately and have different DNA or analogous "life chemicals" than ours. It could prove useful to be able to communicate with our fellow earth creatures, and possibly a first step toward extraterrestial communication.

The earth's core provides us with the essential magnetic field that protects our atmosphere from being blown away by solar radiation. It is theorized that Mars lost its atmosphere due to the loss of its magnetic field....so if no magnetic field is surrounding Mars, then how can we produce a sustainable atmosphere through terraforming?

I purchased an 8" Dobsonian telescope a few years ago and for the past 4-5 years its been collecting dust in the back of my closet. I've had this sudden urge to pull it out again and I was wondering what I should do before using it again. I remember that the mirrors probably need to be aligned again, but that's about all i can remember in terms of maintenance. What I would like to know is what can I do to get the most out of it? Should i replace the mirrors or do they just need to be cleaned? Or have I irrevocably ruined the telescope by not upkeeping it the past couple years? Any other pieces of advice are helpful.

Im constructing my own rocket engines (solid fuel) and they end up being similar to an Estes C motor. When I construct the nozzle end, how important is it to have an exit cone. Ive heard that 30 degrees is the most efficient, but what if you leave the exit hole just a borred hole? Is there any significant difference between the two (or any cone angle)? My engines work great, im just curious on the details. Thanx

Does anyone think on their own, or just follow someone elses path? Do you think speed has a limit?

NASA spends billions of dollars to send little robots to mars, numerous of them with plans to send more and then they say why go back to the moon, been there done that right. Does anyone else think there maybe some covert reson for going back and back and even russia sending probes there. now they admit they found water but NASA scientists who worked on the original Viking mission says they found life. it just doesn't make sense to keep spending the money on a place where you "know" there isn't life and as for mapping it in order to possibly build a livable environ...for humans, do we really buy that. you can map the planet from space.
