They have been studying this particular Sun for over four years, since it was picked out of the 150,000 other stars studied by the Keplar telescope, as a Sun of special interest by several groups of separate scientists.

It appears this Sun has some huge objects orbiting it and it definitely isn't just planets. Many suggestions have been made but none are fool-proof explanations, so some at SETI are saying that although the last thing they think about is alien life, this could be one time where they might have to.

The suggestion is that the objects could be what many have hypothesised in the past, massive mega structures in space like say, giant arrays of solar power collectors which they believe advanced civilisations would erect in space to give them unlimited power.

It has now become such a contentious issue amongst astronomers that several scientists are now working with SETI and are proposing to direct a large radio telescope at the Star to see if they can detect radio waves of a 'technological nature' - if they do then they will ask for the VLA (Very Large Array) radio telescope in New Mexico to be pointed at it for a far more detailed investigation.
the flaw is thinking an advanced Civilisaton would need solar power. Hydrogen is the most common element as such it is the most likely fuel source. or at least the base element from which they create nessesary products.

Hydrogen was the only element that existed after the Big Bang.
It coalesced former into clouds which got denser and denser.
The denser those clouds got the more their gravity increased until they became so large they formed spheres.
Those spheres of dense hydrogen kept gravitationally pulling in even more hydrogen and kept growing bigger and bigger and denser and denser so gravitational strength began to crush the core.
So much so that the pressure in the core caused heat, lots of it, and that tremendous heat and pressure then resulted in two hydrogen atoms fusing into helium.
Fusion. Meaning a nuclear reaction had commenced and the lord said let their be light (and heat) as the first proto stars were born in the universe, undoubted lots of them.
On burning all their hydrogen and with no nuclear reaction pushing outwards massively to counteract gravity, because that is all a star is - a constant battle between gravity pushing in and a nuclear reaction pushing out - those early stars imploded as super nova.
During the super nova explosions other elements were created,carbon for one and even water, and these got exploded outwards into clouds of stardust to form new clouds which themselves coalesced and formed more complex different types of stars( blue giants, red giants and dwarves andstars like our sun.
Which all, depending on their chemical make up, produced even more elements which were exploded out when they too went supernova.
The good news with carbon iron and other heavy elements in the mix planets started to form.
And 4.5 billion years later, 13.5 after the Big Bang, here we are.

Once you've been to Blackpool your search for alien life comes to an end.

Maybe a hydrogen/nuclear fusion rocket would help matters. :dunno:

But even at the speed of light it would take 4.2 or so years just to reach the nearest star, Proxima Centauri, let alone other stars in the Milky Way and 2.5 million years roughly to reach the nearest large galaxy, Andromeda, assuming you can't go faster than the speed of light. Those being single journeys. But, you'll have check on the travel website at the time if two singles are cheaper than a return. :thumbsup:

You do realise power stations and reactors boil water? just saying if you think 80 years is a long time ago?

Having (tried to) read that link I think I now understand the levels of intelligence of the genii who managed to do all the calculations for the Rosetta/Philae mission.
Clever people.

I created a shortcut to that entitled 'something about neutrinos'.

I can't pretend I understood every nuance of your link... :smilin:

...but the implied significance of your summarising comment is very interesting.

I know, I was joshing you. :roll:

I happen to agree - but would add that no technologically advanced civilisation would need to physically travel the vast distances of space in order to pursue their scientific exploration of the universe.

Of course those aliens may have a life span of thousands of years.Who knows??
