Unidentified sounds have been recorded over the course of some years by NOAA, or the National Oceanic and Atmospheric Administration (U.S.).

These sounds are of very low frequency, generally below the 50Hz range and are of unknown origin with ranging characteristics.

Linked in this video are the Julia, Train, Whistle, and Upsweep sounds.

*sigh* Advanced civilizations won't be discovered by ACCIDENT...

The discovery will be intentional and deliberate on their part.

If it faster than light travel as easy as in sci fi is possible and there are many advanced civilizations in universe much older than we are them why they are not everywhere? They should be in the Earth, Moon, Mars, terraformed Venus, and some moons of giant planets for thousand of years.
Since they are not this means that travel in space is not easy (take too long), too expensive, or there aren't so many advanced civilizations around.

Start thinking and planning on a scale of time that is millions of years, not lifetimes.

It would be much easier to seed a planet and let that planet develop and seed 1 other or 2 other planets, in order to spread intelligent life, than to go there yourself, with the limits the lifespan.

The bloom of this "viral" campaign would be much faster than light travel.

Another concept that I personally think is more likely is that generally speaking each planet that can support life eventually creates and starts the evolutionary process...

And, that most of the Universe is within a certain age range (AROUND US), and evolution being a LAW of nature, occurs and approximately the same pace on all the similar aged planets, so AROUND US, so that in our section of the Universe we're all (of the planets capable of it) are developing at about the same pace...so we're all at about the same technological age, give or take a million years...(which is really close)

Terraforming and living in space. Anonymous 15/7/2009(Wed)04:24:15 No.120665    [Reply]
Based on experiences with Earth, the environment of a planet can be altered deliberately: however the feasibility of creating an unconstrained planetary biosphere that mimics Earth on another planet has yet to be verified. Mars is considered by many to be the most likely candidate for terraformation. Much study has been done concerning the possibility of heating the planet and altering its atmosphere, and NASA has even hosted debates on the subject. Several potential methods of altering the climate of Mars may fall within humanity's technological capabilities, but at present the economic resources required to do so are far beyond that which any government or society is willing to allocate to the purpose. The long timescales and practicality of terraforming are the subject of debate.

Mars already consists of many soil minerals that could theoretically be used for terraforming. Additionally, recent research has revealed large amounts of ice permafrost just below the Martian surface down to latitude 60, as well as on the surface at the poles, where it is mixed with dry ice, frozen CO2. It has also been hypothesized that there are vast amounts of ice in the deeper crust. As frozen carbon dioxide (CO2) at the poles sublimes back into the atmosphere during the Martian summer, a small amount of water residue is left behind, which fast winds then sweep off the poles at speeds approaching 250 mph (400 km/h). This seasonal ocurrence transports large amounts of dust and water vapor into the atmosphere, giving rise to Earth-like cirrus clouds.

Oxygen is only present in the atmosphere in trace amounts, but is present in large amounts in metal-oxides on the Martian surface. Some oxygen is also present in the soil in the form of per-nitrates. An analysis of soil samples taken

It has been suggested that Mars once had an environment relatively similar to that of Earth during an earlier stage in its development. This similarity is indicated by the thickness of the Martian atmosphere, as well as the evident presence of liquid water on the planet's surface in the past. The atmosphere has thinned over millions of years as gases have escaped into space, although it has also partially condensed into solid form. While water once appears to have existed on the Martian surface, it now only appears to exist at the poles and just below the planetary surface as permafrost. The exact mechanisms which led to the current atmospheric conditions on Mars are not fully known, although several hypotheses have been proposed. One hypothesis is that the gravity of Mars today indicates that lighter gases in the upper atmosphere could have contributed to the thinning of the atmosphere, with the excess atoms escaping into space. The evident lack of plate tectonics on Mars is another p

So, apparently, there is a species of sea slug that can produce chlorophyll (and absorb it from food). I wonder if this could be applied to humans? If not that, perhaps we could at least have grown animal farms?

>steal genes
It's not stealing actually.
It either accidentally evolved this crap, or got somehow injected with it (mutated virus infection?).
It can survive on it because it's flat, slow and doesn't do much bodily functions. It is not much more than a plant it imitates.

The article says that the sea slug stole the algae genes.
>Sea slug steals genes

I don't think virus could carry algae genes to an animal, virus are specialized parasites, they only attack one kind of cell.

Evolved to produce chlorophyll? Maybe, Chlorophyll is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme that we all produce.
The point is that I don't know how much of the chlorophyl is produced in chloroplasts and how much is produced in the rest of the cell. The article makes us believe that the sea slug produced a identical chlorophyl to the one produced by the algae and not just produced his own original chlorophyl. There are many variations of chlorophyl, I doubt that it would produce the exact one produced in the algae by independent evolution. Or it somehow got the algae genes or it is using live algae cells to produce it. It's known that sea slugs can steal cnidoblasts from anemones so maybe they could do something similar to algae.

No, I don't even know what that is...from context, I assume some sort of TV show.

In any case, You're misinterpreting what I mean by fuel. I fully accept that we can't harvest antirocks out of the earth an burn them. What I'm talking about is taking some other sort of energy (solar, nuclear, whatever), and converting it into antimatter. The reason for this is that a small amount of antimatter has a ridiculous energy density, so in cases where the weight of the fuel is important (like rocket launches), it will make an excellent fuel, no matter where the energy to make it came from in the first place.

Well, a tiny amount of antimatter produces a ridiculous high amount of energy but you need a ridiculous high amount of energi to produce a tiny amount of antimatter. Now remember that there is no 100% efficient energy conversion(most of the energy used to produce antimatter will be lost and most of the energy got from antimatter will be lost too) and that store something that reacts with any matter need constant energy use this isn't a great thing to use as fuel.

TL;DR too expensive and, instable and too hard to store.

this works for getting a signal out (obviously, this is how TV and radio work), but when you consider that people will also need to send signals back, not so much. Especially when you consider how many users that one large tower would have.

Eating kangaroo burgers instead of beef could significantly cut greenhouse gas emissions, according to an Australian scientist.

Removing seven million cattle and 36 million sheep by 2020 and replacing them with 175 million kangaroos could lower national greenhouse gases by three per cent a year, Dr George Wilson from the University of New South Wales said.

I just searched it on wikipedia and they do eat them...

"In some countries in Africa, grasshoppers are an important food source, as are other insects, adding proteins, fat, minerals, and vitamins to the daily diet, especially in times of food crisis. Grasshoppers are usually collected at dusk, using lamps or electric lighting, in sweep nets. They are placed in water for 24 hours, after which they can be boiled or eaten raw, sun-dried, fried, flavored with onions, or used in soup. The "grasshoppers" eaten in Uganda and neighbouring areas are called nsenene, but they are in fact bush crickets, also called katydids.

In some countries in the middle-East, the Grasshopper is boiled in hot water with salt, then left in the sun to dry then it can be eaten like snacks type of meal."

Also seems like mexicans eat them too!

This ordinary-looking bar of chocolate is really a German hand grenade. It's made of steel with a thin covering of real chocolate. When the piece of chocolate at the end is broken, a strip of canvas is pulled out. After seven seconds the bomb explodes.
