correct me if i'm wrong, but i don't think there is a continous connection between the two constants. (for instant, i think that slightly different laws govern electrons that planets)

are ageing differences between races due to some form of evolutionary effects? as in did they provide advantages or disadvantages in certain types of lifestyles of situations?

Apparently the moon gets charged like this every 18 years or so, when its orbit grazes the edge of the Earth's magnetosphere and it picks up a bunch of ions from the solar wind. It could be annoying for lunar astronauts because the surface dust will act "stickier," but that's about it. See: http://sciencenow.sciencemag.org/cgi/content/full/2007/418/3?rss=1

could this build up of static electricity be enough to damage sensitive electrical equiptment on the moon? if the moon was ever to be colonised, would this be a problem?

Oh... fair enough. Thanks for shedding light on my misunderstanding.

??? explain...

Water has been found on an extrasolar planet, according to the bbc...

 

http://news.bbc.co.uk/1/hi/sci/tech/6544257.stm

The radius of the planet's orbit is 7 million kilometers, ~0.047 astronomical units, one eighth the radius of Mercury's orbit. This small radius results in a year that is 3.5 Earth days long and an estimated surface temperature of about 1000 degrees Celsius or around 1800 degrees Fahrenheit.

http://en.wikipedia.org/wiki/HD_209458_b

 

HD209458b is separated from its star by only about 4 million miles (7 million kilometers)—about 100 times closer than Jupiter is to our Sun—and is so hot scientists think about it is losing about 10,000 tons of material every second as vented gas.

water is found on a distant planet that has a surface temperature of about 1000 degrees Celsius and is loosing about 10,000 tons of material every second? How does this water survive, and how on earth did they find it in these conditions?

correct me if i'm wrong, but people of the aisian persuasion tend to lok slightly younger than they really are. i arrived at this assumption because there are several chinese/japanese students in my further maths class who look about the same age or a bit younger than me, yet are at least one year older than me.

would it ever be possible for enough static electricity to built up on the moon for a whole load of electrons to suddenly jump across from one body to the other, a bit like giant lightning?

I have obtained information about university sponsorship from both the MOD and the Navy, but have only started to follow it through with the Navy at the moment. As far as I know, I should not need to apply for sponsorship untill I apply to a university.

I also intend to take a gap year to include a couple of work placements in the subject areas that I will be studying at university, and possibly an expedidtion of some sort. This could also be linked to my subject area.

Does anyone have any good ideas about what I could do for my gap year? Are universities less likely to take people who have gone on gap years or does it not matter too much? Another idea is that by taking a gap year, universities will be able to see my actual A2 exam results rather than just my predicted grades; Does this make much of a difference?

What are the options for living on campus (in general)?

My ideal would be to do a Meng sandwitch course, hopefully with MOD sponsorship, then do a few years compulsory service in the MOD of possibly the Navy. Finaly, I would love to work towards being part of a space program, if possible, and maybe even work in the ISS or something like that.

No your posts are not too late - I have untill next January to make my final decisions.

Recently I have shown some particular interest in both Leeds University and Imperial College London. My subject areas would be mechanical or electronical engineering. Some examples of courses that I'm interested in are:

• space engineering
  
• micro-electronics
  
• nano-technology
  
• mechatronics and robotics

I've also looked at some more general courses too.

If anyone has been to these universities or done courses like these, then please state you opinions. Thank you.

Thanks for that... It seems that I cannot get to the qhole articel any more for some random reason... sorry.

Aside from that, is there anyone out there who has a good background knowledge of these developments and can shed some more light on the details and main concepts?

sorry... you're probably right. do you think that i could post the whole article?

I read an articly in the 28 April edition of New Scientist which sparked my interest. A particle physicist called Philip Mannheim put forward an interesting theory concerning the cosmological and gravitational constants. In essence, he seems to be suggesting that insted of trying to find an ever smaller cosmological constant (CC), it might be a better idea idea to use two different gravitational constants called Gnewton and Gcosmo. The former is used on small scales whilst the latter is derived from particle physics and is used on large, cosmological scales.

A better and more detailed description of the theory is in the article above (click the link above). Please post your ideas about his theory for I would like to know other peoples views. This will hopefully provide different perspectives on this topic and make it easier for me and whoever else reads this thread to understand.

PLEASE READ THE ARTICLE BEFORE BEING TOO CYNICAL ABOUT THIS. (my description is only very brief)

thanks for that... very useful, your statement is.

how can i get it online to put onto here, or any other forum?

I think that the Theology forum hasn't got so many hits is because it doen't seem very well advertised on SFN. I, for one, only stumbled accross it by chance. I would like to see the return of a religion-based sub-forum. I also hope i'll be allowed to join the sub-forum despite my relatively recent joining of SFN.

Who here has seen their god/gods at work?

Who here has seen science at work?

I think that pretty much settles it!

how does one post pictures in here?

That was fun! I only got two wrong! That thing about constantly saying 'dog' kept putting me off.

Ok, sorry. I used the wrong words to state my point. Now that 'julesruis' has kindly posted a link to the article, can we get back to my original question?

What are people's views on this - do you agree or disagree, and why?

sorry... let me rephrase slightly...

I read an article in 'New Scientist' a couple of weeks back, and it basically stated a theory that the universe could be a 'fractal' in that when zoomed out, it would form the same shapes as if you were looking at a smaller area under a higher magnification.

matter can pass this boundary without being torn to shreds if it's small enough and has enough tensile strength.

does anything have enough tensile strength?

What are people's views on the theory that the universe could be fractal rather than uniform?

I went on a meditteranean cruise a couple of years ago, stopping off in Greece, Cyprus, Turkey, Syria, Israel, and Egypt. It was great fun, and i would love to go again. I've also been to South Africa, several places in North America, France, Spain, Belgium, and Norway. I'm hopefully going to Greece again this Summer, and American the year after. (if I can afford it!)
