Deep Impact on Comet Theory
AlexGP writes "Proponents of the Electric Universe theory have gone out on a limb ahead of Deep Impact. They're predicting it will show comets are just rocks and not dirty snowballs.
Controversially they assert comets are highly negatively-charged asteroids on eccentric orbits. As they travel further into the Sun's radial positive electric field, they discharge into space, expelling material at supersonic speed."
Apparently the Electric Universe doesn't believe in Spectroscopy, which has already shown the object to be an icy snowball ejecting gas.
Sort of like how Titan didnt answer whther there are really methane lakes currently on the surface or not.
It showed there aren't large methane seas, which was one theory.
And like how the Mars probes havent told us if there is/was life.
That wasn't the point of Spirit and Opportunity. That was the point of Beagle, unfortunately.
In fact whether there was water is still disputed.
Not really. The discovery of hematite by the Mars Rovers is pretty conclusive. Combine that with the satellite studies that have shown water combined with CO2 in the ice caps, and there is no real dispute at all.
We need to be sending better probes out there that can do some real science.
They are doing real science. Science doesn't provide yes/no answers. It is about gathering data and doing experiments. We are doing more of that now than ever.
Space probes havent advanced in decades.
Considering the amazing Spirit and Opportunity missions and the pictures coming back from Cassini/Huygens as compared with brief visits to the outer planets from Voyager, I find that an very odd statement.
