Wonders of Our Solar System

couldnt they just do some modelling like create models and dynamics so that they can work out what conditions would be like for planets 10% closer to the sun, closer still, further away... and then for different levels of mavity, i.e a different sized planet and how this could effect pysical development?

for there to be a planet with exactly the same size, mass and orbit from the sun and then for it to get the same atmosphere as we have on earth is pretty unlikely...imo therefore

Obviously not exactly the same, but habitable conditions are pretty much guaranteed in the scale of everything.

mavity doesn't matter so much as the life could adapt to that, for instance there's speculation that Mars was habitable at some point in its past.

Because of him it concreted my beliefs that we are alone or at the very least if there is some sort of life it looks nothing like us and isn't intelligent.

There are are estimated to be over 100 billion galaxies in the observable universe, with trillions of stars and who knows how many planets around them, It's a bit of a shame really if you believe were alone.

As for life being similar, and this is just my opinion of course whos to say that if there are other forms of intelligent life out there that they haven't evolved to have some of the features that we have? Bipedal, warm blooded, hands and feet, eyes to process visible light etc.
 
Only just got round to watching last Sunday's epsiode and I thought it was even better than last weeks although it took a while to get started.

Watched it in HD on the big screen too and it really was fantastic. Wish I was clever enough to work in the Space Industry, can imagine that everyday going to work would be interesting. (Ok you might have a few off days ;))

I could imagine for astronomers especially it must be an incredibly frustrating job at times. Measuring readings over weeks/months even just to find out one little fact, or whether theres actually something there where they're pointing their telescopes (black holes, planets for instance).

It must be incredibly rewarding when they actually find or prove something :), or disprove even as is often the case.

Further to that, who's to say that there isn't life even more intelligent than us, and that our features are relatively primitive! :D We can only conceive what we are familiar with, who knows what senses or physiques other life forms might have.
 
Lol, how many locations around the world does he need to go to, my count so far: Norway, Canada, Namibia, South Africa, India, all over the USA...!
 
The numbers are too staggering to believe that we are alone in the universe.
We began as simple lifeforms, and have evolved into what we are today, this prosses is not exclusive and is the fundamental survival tool for life itself. Its real and any one who cares to argue otherwise will be doing so with blinkers on.

Now our galaxy the milky way is home to 8 planets, one inhabited by us, another that gets the imagination running wild about its possibility's to be able to sustain or have sustained life, that being mars.

The Hubble telescope site estimates there are hundreds of billions of galaxy's, a German super computer simulation estimated it may be as many as five hundred billion, now each one of these will have numerous stars, like our sun and if one of these has a planet orbiting it that can in theory sustain life thats a possible five hundred billion chances at the fluke of nature that created us happening again or have happened before.

To dismiss life on other worlds when you look at the numbers is more than ignorance on the part of the human race, id venture that the question isnt if there is life other than our in the universe its how many other forms of life live out there.

Indeed as you say the question isn't really 'is' there other life out there) more a case of how common is it in the universe. I think the drake equation tried to estimate a probable number of civilizations in our galaxy.

Im always amazed with some of the facts and figures that crop up for things to do with spce. I knew Jupiter was big but i was amazed when Cox said that the big red spot storm was bigger than several earths.

I noticed this as well and towards the end the last edition of Top Gear came to mind, where Clarkson went to Australia to check if the glove box still worked.

Indeed, i was amazed when it was stated that even though there are billions of stars etc in a galaxy and that galaxy's are so vast, if two collide, an event that takes millions of years itself, there would likely be no major collisions between stars and they say like 99.9% chance!

It is just so staggering when you try and comprehend just how large our universe is. People say we are like a spec of sand floating in the universe, that could not be further form the truth, we are to the universe what a single atom is to hundreds, perhaps millions of our galaxy's!
 
Another great episode, thinking of starting a trip to Titan if anyone is interested ;) Wonder what Methane tastes like to drink...
 
Brian Cox

Anyone remember the programmes he presented for Horizon about a year ago? One of the subjects he 'covered' on Horizon was Time. He was a stuttering, mumbling and confused idiot through out he whole 60 minutes, it was embarrassing. I had to google him afterwards to find out if he really is a professor and to my disbelief he actually is! He is a professor and yet had an amazingly hard time roughly explaining things in simple terms.

I went out of my way to not watch the first episode of Wonders of Our Solar System just because he was presenting it, the Horizon programmes left such a bad taste in my mouth of someone that doesn't know what he is talking about.

Watched the second episode and he has improved but I still find him very annoying to watch. I don't see him as a role model for science or a driving force for physics... maybe you like how he smiles non stop (even while talking).
