How do they inhibit space travel?

Man and unmanned?

What are current methods of handling g forces?

When are g forces experienced in space travel(only when leaving the atmosphere?)?

 

Thanks.

Current methods of handling g forces...I saw a program where they designed a suit that would help deal with g forces. What it did was squeeze blood from the legs into the upper body. When high g forces are reached, blood tends to leave the upper body and brain, causing people to pass out. The suit manage to ensure that blood stayed in the upper body.

^I wouldnt get your hopes up. There's bound to be a flaw in the theory. Its just that I failed to spot it.

The thing is, if it is scientifically plausible that space can enter from a higher dimension then it has about as much evidence for it as dark energy - nothing. Of course, this theory could also link to a multiverse type proposition.

Thanks for your sugession

tRNA is transfer RNA not because it is important in protein synthesis. it is transfer RNA because it transfer the amino acid in translation. Like that everything which is going on, has some reasons. I want only healthy disscusion.

...lol, I was trying to keep it simple for you since I didnt realise you knew of translation. Translation is a part of protein synthesis so my point remains the same and I stand by my original comment:

Just to add, the reason tRNA got its name isnt because it has Thymine. Its because it stands for 'transfer RNA', which is very important in protein synthesis.

^Oh, shhhhhh.

I mean, the technical layman's term is "brine". At least, thats what Im supposed to write in my Chemistry exam when they ask for the non-chemical name.

Btw, technically its "an aqueous solution of sodium chloride".

Whoa, that is really weird/interesting. Are you suggesting that space from another, higher dimension is somehow leaking through into our Universe, causing the expansion?

Since I dont have a good understanding of higher dimensions, I dont know if that is even plausible, but its a fascinating idea. (I assume I understood you right). It sort of reminds me of the theory that gravitons are leaking up into higher dimensions. Your theory would also explain the 'rich get richer' and the 'poor get poorer' scenario we have for galaxies. This is where galaxies get more and more unevenly distributed. This can be explained by normal theories, but by your theory it should mean that this effect would happen at an accelerated rate.

Anyway, Im trying to think of a serious fault with the theory, but Im not knowledgeable enough to give you one atm. Nice thinking!

Btw, thanks guys for your explanations. Interesting stuff.

^Damn. Beat me to it.

I usually ask that question involving an island and two paths. Its nifty.

I looked all over the internet to find an explanation for why sublimation occurs, and couldnt find any.

You say that they aren't 'sticky' - then why do they form a solid eventually? Why dont they just remain gas. I personally would like to know the scientific explanation.

As you increase the positive charge in the nucleus, the electrons are pulled in more causing the radius to decrease. But this is more than offset by electronic shielding when a new shell is formed.

Try and see the pattern that emerges, although sub shells confuses things a bit I think.

Just to add, the reason tRNA got its name isnt because it has Thymine. Its because it stands for 'transfer RNA', which is very important in protein synthesis.

...I believe the technical term is 'brine'.

^My advice - get a good text book geared towards some sort of qualification. Read the textbook, do the questions, if you have problems ask on the internet. Then, when you're ready, take the exam.

Thats assuming you want some qualifications in something scientific.

I say this because I understand far more cosying up with a well-written text book than I ever did at school. A little boring, but worth it.

(Sorry for getting off topic)

Im doing a project at the moment involving using redshift data measured photometrically. This is opposed to redshift data that is measured spectroscopically. Could anyone outline the main differences between photometric redshift and spectroscopic redshift?

Also, the photometric redshift measurements are obtained using different methods. There's a Neural Network based 'empirical' method and there are template based methods. Some of these template based methods are Bayesian.

Can anyone explain what this all means? I have to write a paper up which explains how the methods are different, but the explanations need to be as concise as possible (A sentence or two for each term).

Thanks

Just to add...

Basicaly its on what was there before the big bang. We know that when star dies it usually implodes then explodes.

Thats only for stars with a mass of greater than or equal to 8 solar masses. Otherwise, a supernova will not occur.
