UFOs, new tech, it all goes in here. Have you tried switching it off and back on ?

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.

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

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:

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

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.

That's assuming the Big Bang is the 'correct' answer. There have been various other theories put forward. One problem with the Big Bang theory is 'what was there before', as essentially in simplistic terms we are talking about something coming out of nothing, which defies our current knowledge of the laws of physics.

I predicted you'd make that post before you'd even made it. Food for thought eh! That's how original you are. FYI, Luton has had a lot of investment over the last two decades. You should see the amount of building work going on right now, including at Luton Airport. Luton is becoming a dormitory town for London commuters, which is bringing a lot of money into the town.

Spoiler: show
The Thameslink Programme, which is costing £5 billion.
Luton to Dunstable bus link, including a new bus interchange at Luton.
Luton airport expansion.
The Galaxy Centre.
Investment in the University of Bedfordshire, including new student accommodation.
A new road bypass by the railway station.
Pedestrianization of various places in the town centre.
Refurbishment of The Mall, plus an extension.
Improved bus links to London and the airport, including a 24/7 bus service to/from Luton/Dunstable and to/from Luton/London.
St George's Square major improvements.
Luton Airport Parkway Station and in the near future the DART project.
Napier Park.
etc.

Since 4 dimensional spacetime doesn't come into being until after the big bang there is no "before".

It is mind boggling isn't it?

4 dimensional spacetime, Branes and string theory etc etc?
.
One brane bumping into another causing A big bang and the creation of a new universe out of nothing is a fascinating concept that could perhaps explain the big bang but that is just a theory...

Mind boggling indeed, Raven. But once we learn to think outside of "causality" and "dualism" it becomes graspable...

...just. :ooer:

This is the difficult bit to get our heads around, that technically the laws of physics can change with the passage of time. And what is time anyway? Time for us as in 24 hours in the day may be different for other life forms in the universe. One other problem with 'the universe has a boundary' theory is 'what is beyond that boundary'? There are so many things we just don't know (yet).

We haven't even mastered nuclear fusion, which basically runs the Sun.

ETA. We just have to accept the fact we are a pretty basic life form on an insignificant planet, orbiting a pretty insignificant star (the Sun) on the outskirts of one of billions of known galaxies in the known universe. So, why are we here and what is our purpose? Have we got a purpose? These sort of questions.
