habitable planets question.?

in fact we can use our own Sun,When it starts to expand all we need to do is drag earth back as far  as Jupiter and send it round the expanding sun ,that should give us another couple of billions of years of life,and its no problem organizing an orbit that suits,which also means we don't have to worry about the globel warming that supposed to be coming ,we can always move the earth back a million miles.Its time the scientists of this world got off their backsides and start to listen to brass and stop fecking about telling us we need to move to a new planet.Time to think about how is best to move mother earth on a new orbit.

Looking for aliens, not somewhere to move to.

brassneck, you really need to stop drinking and posting at the same time

And the moon will come with us,its in orbit round the earth just shift the earth an few inches at a time to correct the orbit,its not rocket science ,its so so simple."NOW all the scientists who read this will say to themselves"now why did I not think of that"
And in a few months time we will hear that Some fuddy duddy scientist in American is starting to research the possibilities of re orbiting the earth.But you all know that it was brass that told you first and it was brassnecks idea.

hi Scan,i just thought I would liven up the Wednesday night chit chat.

A brilliant idea, Brassneck, you will go down in the annals of science alongside Newton, Maxwell, Einstein and Dirac. By the way, the moon doesn't orbit the earth, both moon and earth orbit a common centre of gravity situated just below the earth's crust.

Foinavon-the moon DOES orbit the earth. Mankind will die out before it finds an habitable planet. Either that or the indigenous population on the new planet will ban immigration, just like what the UK shoulda done!

Dr Slicer, your qualifications and sustificates are most estimable but I fear that the concept of the barycentre of orbiting bodies may be new to you.
Here is an article about it for your delectation.(unfortunately, they employ abhorrent colonial spelling, but that is becoming the way of the world).

You want to "Moon Base Alpha" the Earth onto an adventure filled Space 1999 journey through the cosmos?

I'm up for it if I get to fly an Eagle Transporter and get a knuckle duster laser gun.

the moon still follows us round the sun,so where ever we go its coming with us,we need it for the tides.
by the way if I am sitting in my sitting room in front of a big open fire in the middle of winter and I am getting too warm I move my chair back and I am not too warm I don't go over to America to look for another fire that is smaller than the one that's in my sitting room.BUT scientists want a new planet for mankind because we are going to get roasted when the sun starts to expand,so its not beyond the realms  of possibilities that we change the orbit of our earth after all we have 4 billion years to think of how we can do it.its a better idea that travelling 300000000000000 hundred thousand million light years across the cosmos searching for a new home.

Sounds like someone is trying to be pedantic to appear overly clever The moon orbits the earth, and the earth orbits the sun, the precise centre of rotation is total nit picking. If you're going to be utterly pedantic you'll get to the point that you say nothing orbits anything.

And if someone invents a time machine in the next 4 billion years we wont have to worry because we can always come back to today  10th august 2017 (the day brassneck thought of the concept of the time machine)which is now recorded as a time when globing warming is only starting.(I wonder will some one stumble across this thread in 2 or 3 billion years time)

Don't hold your breath !

always loved the quote on the big bang theory when they accidentally buy the time machine from the film of the same name, and Penny says "it looks like something Elton John would drive through the Everglades"

Time travel impossible nonsense

It's just Newtonian mechanics, JC, worked out over 300 years ago and taught to schoolkids in physics lessons. The moon goes round the earth as it orbits the barycentre only because the barycentre happens to be close to the centre of the earth.

Albert Einstein quote "the possibility of  time travel is not as impossible as people might have you believe ,in fact it is my opinion that it is possible and the math is there for anyone who might care to look for it."
Now who is going to argue with the great Albert /In fact I think I read somewhere that quantum science have a theory on it that is agreeing with the great Albert statement ,something to do with photons disappearing and popping up somewhere 8 miles down the road an hour before they disappear.

And may I add that we all heard of black holes that nobody has ever seen yet,(only effects) let me introduce you all to worm holes that crawl the universe that some say are tunnels back in time,So if we find a worm hole all we have to do is drag the planet earth or drive or orbit the planet earth through the worm hole in 3 billion years time and we will arrive back to NOW.
Come to think of it"who says an future civilization hasent already done it and we are the product right now of a future generation that has returned to the past.The mind boggles.

Einstein envisaged all of space-time existing together, the past, the present and the future but we are only able to access the present while moving through space-time at the speed of light. The past has not disappeared, it has only become inaccessible to us. The future is waiting for us. This is how he leaves open the possibility of time travel.
We don't see any evidence of future generations coming back to us and it leaves open a lot of strange ideas for sci-fi writers to toy with. Who knows what is possible?

If the moon goes round the earth, as you say Mr Foinavon, Shirley that means it orbits the earth. Of course I was edumacated a long time ago and astronomy must have changed since then.

Some of us love the precision of physics Dr Slicer and I was just trying to give the proper definition. Others enjoy collecting stamps, there is room on this earth for all of us. I take your point good sir.

Are you still trying to say the moon doesn't orbit the earth because the centre of the orbit isn't the centre of the earth? Surely you are trolling? How about say ..
https://en.wikipedia.org/wiki/Orbit_of_the_Moon

Every single thing has a reciprocal gravitational force and everything is subject to the sum of all forces around, obviously diminishing with distance.

From a purely pedantic viewpoint if you had one superhuge sun and a rock the size of a VW beetle orbiting it, it wouldn't be orbiting it as the "barycentre" is say 1 x10-89 m from the suns centre of gravity. Pedantic nonsense of course.

In fact the link you posted about barcycentres talks about the planets orbits around the sun. Or the asteroids. But in your opion they must not "orbit" either as the sun is under a reciprocal force?

Read my post to Dr Slicer.

Not very good at reading because I am illegitimate!

JC - words in science have very precise meanings

I would argue that Foinavon is being accurate rather than pedantic.


Anyhoo, the thing about the "habitable" planets is how can we be sure that they have a magnetosphere. You'd be toast without one.

What about a tin-foil hat ?

Now we are in pedant mode, are tin foil hats really tin? They are far more likely made of aluminium :P
That's what mine is, and it's why the MIB can't track me down to remove the probe the grays left in me.

I thought they put the probes up your arse

Who said it isn't? Ooh Jeshush Chrisht!

I'm sure Bito could check for you.

slave from south park?

Is there any actual benefit for trying to find life on other planets light years away, as interesting as it is ?

ok,you go to a parade of animals that starts at 2pm.the elephants walk by you and they lead the parade,AT 3pm the cats pass you.at 4 pm the monkey's pass by and at 5 pm the dogs walk by and the parade is finished.on your way home you say to yourself that was a great parade of animals and it lasted 3 hours.When you get home you tell your brother that you were at the animal parade and it lasted 3 hours.But your brother says to you."he was in a helicopter and watched the parade from above and seen the elephants,the cats,the dogs,and the monkeys but he only looked down at it for a few seconds,but he seen the parade from start to finish.
this proves that Time does not exist and that its were you are positioned that makes you think its a long time or a short time.
So Einstein is correct =There is no such thing as time its a man made thought of the mind.And it follows that the great Albert is correct when he says "everything happens together,there is nothing only the present"

Sort of on the same subject ,it says in the bible that one day a man asked Jesus that if he was married and his wife died and he remarried which women would he be with when the three of them went to heaven.To which Jesus replied "there is no age in my kingdom"
Now how did that appear in a book written thousands of years ago when it was Albert Einstein who discovered the concept of no time and no age.
