A final message from Earth?

[cee-dee]

Some people want to add a "final" message to the Voyager spacecraft but what do you think?

Who do they think might "find" the spacecraft? Surely any recovery would have to be done in space? If the craft headed in to any "occupied" Planet, wouldn't that Planet have to have an atmosphere of some sort which would cause the craft to burn up as it entered?

As the craft are travelling at nearly 40,000 miles per hour, how do "they" expect them to survive any "planetfall" leaving enough of the craft intact so that "someone" can read the data on/in it? Seems a daft idea to me.

Logic dictates that there must be other life out there taking in to account the billions of stars in our own Galaxy never mind all the others.

Well, you never know, perhaps speeds faster than light are possible, thanks to EmDrive and stable Warp Bubbles.

The idea of traveling to other planets at speeds much faster than light has seemed impossible for a long time.  If only it were possible, planet to planet exploration would be almost instantaneous and open the galaxy up for man to explore.

However, much of the scientific community has long believed that traveling at speeds faster than light is physically impossible, no matter the material, and accelerating something to those types of speeds simply can't happen.

But, there are those in the scientific community that do believe that faster than light travel is possible, and one team may have just accidentally stumbled onto faster than light travel.

A team of researchers at NASA unintentionally accelerated particles to faster than light speeds using the EmDrive resonance chamber.  If their findings turn out to be accurate, the team may have just discovered faster than light travel.

The EmDrive is a proposed method of interstellar propulsion and could even end up being the engine that propels starships through the galaxy in the future.  There are many advantages to using this engine.  It's electrically powered, it doesn't have any moving part and doesn't require any material fuel to move.  If it does work as planned, there is a good shot that this could be the first steps in the design of a brand new engine.

NASA is currently studying the new technology for future use, but no one expected these types of results.  When the team of researchers fired lasers into the resonance chamber, the particles were accelerated to astronomical speeds, with some even exceeding the speed of light.

"...this signature (the interference pattern) on the EmDrive looks just like what a warp bubble looks like. And the math behind the warp bubble apparently matches the interference pattern found in the EmDrive." 

So what does this mean for space travel as we know it?  Well, it is possible that NASA accidentally created a warp bubble that could, in theory allow for fast travel between the planets of our solar system and beyond.  While it sounds like something out of Star Trek, it is indeed now a part of real science.  If the EmDrive were able to create a stable warp bubble, traveling the stars will become easier than ever and could propel the human face to where no one has gone before.

Whether it would ever be possible for a spacecraft and beings in them to travel across space, who knows. 

It's enough to boggle the mind.  I'd pack some Nurofen.

More about what messages we would send.  I think we are mad to be advertising ourselves to other lifeforms. Some romantic and naive notion about contacting extra-terrestrials.  If they get the messages they are likely to be hugely more advanced. 

They might not be interested in us, but there is no reason to think they would be benign and might find our planet an attractive resource (if we haven't completely messed it up).  As Stephen Hawking said - human beings have a terrible history of mistreating, and even massacring, other human cultures that are less technologically advanced — why would an alien civilization be any different? 

My message would be, with apologies to the League of Gentlemen - This is a local planet for local people, there's nothing for you here.

Not that that would put them off!

I don't see why or how that assumption can be made - any message sent out into space by us is unlikely to be discovered before many millenia have passed due to their relatively slow speed.  Who's to say what level of development we will have attained by then?

We are just as likely to be far more developed than any visiting estra-terrestrial.

The above is not as difficult to understand as it originally looks ( ignore the formula ) and scroll down to the chart. The "Escape Velocity" of Earth is approx. 25,000 miles per hour, the "Escape Velocity" of Saturn is approx. 3 times that of Earth.......so 75,000 miles per hour. That means that if anybody landed on Saturn, they would have to be able to travel at a speed of 75,000 miles per hour; in order to get off of it again. As we haven't been able to attain speeds anywhere near that, it might be a good idea to start there.  If there are ANY life forms out in the universe, they will either be stuck on their "Rock"...as we are; or they will be way ahead of us and the only reason they would want to come here, would be to colonise our Planet...........because the events outline in my previous thread will happen to their Sun also.

Thank you.  And I wasn't doing to bad till I got to 'Deriving escape velocity using calculus.'

I think Professor Stephen Hawking is correct to believe that an Alien culture, looking for resources to survive, would be a ''BAD'' encounter, and we need to be prepared for that. (Whether we can do anything about it, remains to be seen.)

However, we also need to be prepared to recognize a ''Good'' encounter, prior to jumping to conclusions.  We are intelligent beings, beyond our instinct's, we must assume it's possible that others are past our greed and ignorance. This is quite an EVIL place (well Hell for so many) They might think they cant cope with that. Who would blame them?

Voyager 1 is now 12,430,200,000 miles from Earth, an astonishing distance? (It'll soon be way further out making that distance incorrect)

Amazing they can still communicate with it but taking in to consideration the time it takes to get a message to it, it just shows you that the speed of light is far too slow for travelling any great distance in Space?

lol, I am sorry but that really is a very funny statement coming from someone who professes to have a real logical mind

No way does  logic dictate such a thing, in fact it will dictate quite the opossite. 

Also where is the logic in stating, with the probability of 1 in 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, re-ocurring that life began from  nothing. because those are the true figures.

Logic dictates you cannot get something from nothing.

It's pretty obvious that on the balance of probabilities, other life forms must exist elsewhere in the Universe and also in our own Galaxy where we can see about four new stars being born every year.

Far from there being "nothing", there is an awful lot of something out there.

Therfore, it's logical to assume that we are not alone but how far away our nearest neighbours are how how "advanced" they are is something open to conjecture until we make contact.
