Have aliens visited earth?

Arguements that Physics does not allow for faster than light travel hold very little weight when are current "understanding" of the universe is based on vast assumptions/guesses regarding dark matter and dark energy. To say we understand the universe, but we're not sure what 75-90% of it is, seems a little silly.

Yeah, I really don't think we're close to understand even half of the universe mysteries/secrets

You people need to read Cosmos by Carl Sagan.

He goes into detail about space/light and in essence TIME TRAVEL...

awesome book

Physics do actually allow faster than light travel. In fact, there are several particles travelling at a speed faster than light.

Thanks Tim but I've already read that book. If you have another suggestion I'd be happy to take you up on your offer otherwise I could reread it (it's been about 4 years).

That's OK, I just thought he had some good points that pertain to this thread. I will take a look at Rare Earth and see what I think. I will probably be going in looking for ways to refute each point they make, but who knows, maybe I will be swayed.

You must know something the rest of us don't. Do tell.

I don't think you realize how vast the search space is.

Let's take a Shakespearian sonnet.

as an unperfect actor on the stage
who with his fear is put besides his part
or some fierce thing replete with too much rage
whose strengths abundance weakens his own heart
so I for fear of trust forget to say
the perfect ceremony of loves rite
and in mine own loves strength seem to decay
oercharged with burden of mine own loves might
o let my books be then the eloquence
and dumb presagers of my speaking breast
who plead for love and look for recompense
more than that tongue that more hath more expressd
o learn to read what silent love hath writ
to hear with eyes belongs to loves fine wit

Ignoring punctuation and capitalization, there are 596 characters in that sonnet. Assume our typewriters have 28 keys---26 letters, one space and one line feed/carriage return.

Let's take a monkey and make him hit 596 keys and stop. If it's the above sonnet he gets a banana otherwise we continue starving the poor bastard and he has to keep typing. The number of 596 character-long blocks of text is 28^596. Let's estimate

28^596 ~ 27^596 = (3^3)^596 = 3^1788 = (3^2)^894 ~ 10^894.

So there are 10^894 blocks of text. Let's assume our little monkey can crank out 100 characters in one minute. So approximately every 6 minutes he'll crank out a 596 character block and thus approximately 10 every hour, 240 every day and 87600 in a year. Let's just say 87600 ~ 10^5 so that the approximate number of years for the monkey to produce the above sonnet is 10^889. There are only 10^80 electrons in the universe so at most 10^80 monkeys. With this many monkeys we're producting approximately 10^86 character blocks of length 596 in one year and the approximate number of years until the Shakespeare sonnet is produced is 10^808. The sun will have expanded and swallowed the Earth long before that.

Sounds like almost like an intelligent design arguement.

Is that why antibiotic resistant strains of bacteria can evolve in 15 minutes thanks to a little ultraviolet light?

Is that why entire new families of PCB digesting enzymes evolve in the soil in 90 days?

Is that why viruses have developed compression algorythms for their own DNA?

Your math is flawed. It's not about random permutations of ATCG's. It's about folding and charges.
