Steven Hawking warns not to talk to aliens

[Otherright]

I am a bit more optimistic, however my technical knowledge is limited.
I still drive a car, soon though I can be just a passenger to the machine.
I can say this though:
The arrangement of molecules to survive the temperate climate of a star should be an objective if an energy dependent civilization is to ever get away from their star system. I speculate they can mine the centroid star(s) to reduce its/thier energy while at the same harvesting the energy that is removed. I also speculate some kind of engine or apparatus of some type devoted to energy manipulation so forced solar flares or equivalent can be harvested... "The Flux Capacitor" or "The If Jesus Only Told Us Box" might be cool names.

OK.
A) How do you speculate they could mine this?

B) This is the big one, how do you harvest a solar flare in an area 30,000 times the size of our planet? How big would that apparatus need to be?

C) If you could build it, how do you know it would harvest the energy needed? How do you store that energy?

There is good science and good science fiction. There is bad science and bad science fiction. Kim Stanley Robinson is good science fiction. Ben Bova is bad sci-fi.

 

[St Giordano Bruno]

I think climate skeptics are more dangerous and a threat to the long term health of this planet than being invaded by aliens as a direct result our chance communication with them.

 

[AmbiguousGuy]

Is Hawking right, or should humanity be trying to communicate with other races?

I think that any aliens capable of reaching us wouldn't have the least interest in anything we have. They'd be billions of planets between us and them -- if they're just after raw materials. Many of those planets would be as livable as Earth, in my opinion.

If they saw us as (eventual) competition for mastery of the universe, that might be a problem, but more likely they'd just be curious about us, sending their Cultural Studies crew our way.

Maybe they'd take a few of us as zoo specimens. It might be wise to lay low until the unlucky few have been collected.

Clearly, Mr Hawking is aware of the documentary, Mars Attacks.
It shows what would happen if aliens visited us....although I don't think our violent obliteration would actually be accompanied by a theremin

C) If you could build it, how do you know it would harvest the energy needed? How do you store that energy?

A) design would have to occur of an apparatus or tool ( which ever you prefer ) that could withstand the forces of the star, knowledge of molecular arrangement and which molecules to arrange would most definitely be included within the design paradigm. In addition the civilization would have to be able to survive the molecular arrangement and the molecules chosen. So, they would have to adapt either through their manipulation of technology ( which again could be referred to as tools ) or manipulation of their physical constitution.
B) This energy dependent civilization would not have to harvest natural solar flares per se' at first (although that technology comes later) but their tools must survive the flares so that the mining operation can occur.
C) You wouldn't necessarily have to save the energy. They might be able to suck it out like a straw and get that sucked out material further away from the core of the star(s)'s position until the star has been moved to the location of the operator(s) of the apparatus OR the star has been moved to a location away from the operator(s).

after C is complete I guess you would just move across the ?pipe? closer to the star that is now in a different location and start the process over, but this process would be used just for interstellar travel.
I speculate a different method of harvesting stars has to be used for inter-galactic travel, although I haven't considered what it would be for more than a few seconds in total.

 

[Vendetta]

figuring out spaceflight is one thing.
voluntary interstellar travel would require stellar energy because it takes more energy than planetoids could yield to get to another star.
if you took all the planetoids in a given star system you couldn't escape the gravitational pull of the centroid star(s) of the star system.
how do you propose to manipulate the planetoids of a given star system to yield an energy that is greater than the centroid star(s)'s gravitational pull?

Who cares how they acheived it? My best guess is any ancient civilization is far advance than our own so I would say whatever kind of travel they have attained is more plausible than not

how advanced of a civilization is the civilization that the natives who live within the amazon have that do not drive cars, do not have modern medicine, do not have telephones, do not travel the sky, do not know what a space shuttle is, do not have electricity, do not understand atomic theory?

Tis not that it will happen, but that it could.
One of the jokes in the movie is that the intelligent & progressive scientist proclaims that advanced aliens must be peaceful.
He discovers otherwise. We don't know what values an ET would have.

 

[Evolutionary Model]

I think the chance of finding them is low enough to try, if that makes sense. I think it's worth the risk.

C) If you could build it, how do you know it would harvest the energy needed? How do you store that energy?

You dissasemble the entire solar system and rebuild it as a computer/solar panel combination fully enclosing the central star. There's your energy.

this ability would be characteristic of a level I civilization, its not bad that you can imagine this considering you are from a level 0 civilization.

I've seen that movie before if it was the one where they took them down with music or something...


Anyways, I do agree aliens would attack if felt threatened, just as any animal species. But if they have human machines or the future of human machines is what I absolutely doubt.

Don’t talk to aliens, warns Stephen Hawking - Times Online

Kinda like being told not to talk to strangers....Now, Hawking is a major proponent of the idea that other beings are out there...but it's better off not letting them know about us and keeping a low profile....

Is Hawking right, or should humanity be trying to communicate with other races?

Hawking is ignorant on this subject


we are still very primitive

if another race managed to climb off their rocks and master space travel

what choice would we have on the matter when it comes to communication.??? ZERO if they wanted to do so. [if they even give us a chance]


it would be the same if we even decided to try and communicate with ants

we dont even know communication would be possible.

 

[PolyHedral]

I can imagine turning the entire non-stellar (you can't disassemble the stars without magic) galaxy into computronium, but I have absolutely no idea what you'd use it for.

Any race that found us would probably want to communicate, since there's little reason to make the trip otherwise. If they could make the trip, communication would be completely trivial, though largely pointless. There would be nothing for us to say.

it sure wouldn't be used for interstellar travel if you couldn't use it to move the star.

 

[PolyHedral]

How patient are you?

Though again, there's very little reason to move the star, since there's probably little reason to move anywhere.

I am interested in energy sources separate from the energy the Sun can yield, but then again I don't want to die.

What he says makes sense. Think of it like this, if the human species was advanced to a point where we could visit other worlds, knowing what you know about our species, would you want to be part of the less advanced world that contacts us? I know I wouldn't.

is this the scenario that you are thinking of:

knock knock,
hello, we are here to bring you the word....
