Dark matter is proposed not to couple to electromagnetic radiation - this is the reason we "see" things, not because of size. Z bosons are 160,000...
Thanks, I just randomly thought "I wonder how SciForums is doing" and took a look. Occasionally in the past I've checked up on how people like...
Is it more difficult? Depends your preferences for mathematics. I personally preferred it to FEM. You need calculus, linear algebra (as much as you...
The use/nature of infinity, within mathematics, requires careful definition. Even something like "Is infinity a number?" is open to multiple answers....
Reiku... I have not been on this forum for probably about 5 years. Before that you and I go back probably another 5-8 years. Through all that time...
I find it funny how you always fall on the slightest discrepancy in any piece of the mainstream and you always predict precisely what the experiments...
I just scrolled quickly through the last 3 pages since my last post and given I don't see any algebra from chinglu I'll conclude he continues to be...
Both Rp and I have addressed your claims. Unlike your arm waving assertions we did the algebra and demonstrated that you do not understand what SR...
Yes, you must always be able to rearrange an equation to make it dimensionless, though few people ever bother for practical purposes. If I have...
As has been said, geodesics are ALWAYS lines, regardless of dimension. There are higher dimensional generalisations, such as surfaces of minimal...
Chinglu, if you want to endlessly talk about the same damn ignorance you have about light spheres then do so in the pseudo section. You had your...
Someone mentioning Lorentz transformations does not mean the effect is strictly due to special relativity. General relativity includes Lorentz...
Well done, you've just shown you cannot do a 1st year undergraduate homework problem. You also show you do not understand the GR notion of time,...
That simply gives an extremely brief overview of how GR formalises the notion of time. I asked you to do the calculations which describe the system...
No, I'm afraid it is you who shows that. Let's do a little bit of basic logic here. We have some observation X. Someone puts forward a proposition A...
Depends on the precise nature of the variation and how that feeds through to the kinematics of systems. As pointed out in one of the links, we know...
I think it is a mistake to try to put a label defined in our everyday work, such as particle or wave, onto something utterly outside of our...
You do not 'validate' a theory by mathematics. Also, don't delude yourself by thinking you're doing as Newton and Einstein. Mathematics provides a...
Bingo. I will point out that when doing this for (if memory serves) rank deficient problems you will still not be able to get a good answer. For...
It is really that nothing with units like mass, length etc has fundamental physical meaning, since our choice of units is artibrary. Why pick metres...
