The size of the "Suns" can be measured quite acurately by looking at their absolute magnitudes and measuring the radiation they admit then placing them on a Hertzsprung Russell Diagram. We don't need to compare the distance between our Sun and Earth with other stars and planets because some stars are much hotter making a planet the distance of 1 AU (the distance between the Earth and the Sun) from it too hot to contain life and some stars are much cooler therefore the planet needs to be much closer.

Thanks for your information Jack.

Astronomy is a subject I don't really cover much and I know I am not alone on that score, but it is always nice to share opinions of what people know.

It is amazing what astronomers/scientists can find out, regarding Suns so far away. It is a pity that we can never get there to find out.

I did say before to you:- If he can prove himself, I may be inclined to agree? Your contibution above is very convincing:thumbs:

I sometimes reply to threads like this, just to create a debate and if members tactfully explain what they know, I shall pick at bits & pieces, etc.. (just to create a debate), regardless of what I know or don't know? But sadly Jack, some are not so tactful and that progresses into a War of words with agressive tones....

Suddenly, your post came in and I apologise if I went over the top with you.:sad:

I personally think that there is no life on other worlds, but that is just something I believe personally and it has nothing to do with proof, as we can't get proof anyway, as there is no way for us to reach other solar-systems where those closest two Suns are.

But, with technology improving year by year, who knows what could happen in the future.

I shaln't bother replying to the other two members who have commented in this thread, as it is just a case of going around in circles, etc...







nodisharmony :angel:

can we debate the topic at hand and steer clear of making personal comments about each other. Each and every person has brought their thoughts to this thread and it is not for anyone else to be-little them.

Not only do we have the ability to detect planets orbitting nearby stars, we can now detect the water vapour in an atmosphere of a planet orbitting a nearby star

Wow. That's quite amazing. I think it's quite probable that there is life existing on planets orbiting nearby stars, closer than we think, let alone the whole universe.

I'm in total awe of the people who created a system where we can detect water on a planet trillions of miles away.

Mathematics - the bane of schooldchildren, I hated it as well, is what the teachers always said it was - the key to everything - astonishing stuff

Hey Spacebandit. Thanks for the link. Fascinating stuff. On the images bit, they are just tiny sections of what is out there. Just simply WOW. How anyone could believe out of all that stuff out there we are the only ones. For the record I believe that there is life out there but not in aliens visiting us.

Same here, we're not alone but we won't meet the neighbours in our lifetimes.

And you know - I feel a Python moment coming on :

Sorry mate, did that back on page one. Always good to see it though.

Indeed you did. apologies for the repetition :flowers:

But as they say - you can't get enough of a good thing

Indeed.
