Hijack from New forums on SFN
So, you think your ideas, that were spawned casually, should be given the same gravitas as someone who has jumped all the educational hurdles and done diligent research spanning years/decades?

Transgender athletes
They will declare use of those substances, so what is the issue? The ultimate effect on fair competition cannot be known until it is tried. Yes. You can't hypothesize the outcome, you have to try it.

Transgender athletes
Trans status will be declared, so it's easy enough to monitor... and differentiate fraud. Time and research with subjects in a more hospitable environment should elucidate best practice going forward.

Question light and UV and cardboard box
I think pro photographers shoot in raw now for future proofing and sound is done in 1-bit.

Question light and UV and cardboard box
Ha! They aren't putting their money where their mouth is. I think for reliable archiving, discs need to be physically etched rather than alteration of a dye. as are commercially-printed disks, which I think have the data pressed into foil in a series of pits.

Question light and UV and cardboard box
This is true, I was just thinking of uv photon exposure. There is off-gassing as well from the media and container. Paper/cardboard should be archival quality, with no off-gassing, as well.

Accelerated aging tests. I know what you are going to say next. No they don't have a Tardis. Material degradation is a function of exposure to the source. So, if you double the intensity you halve the time to reach the same state of degradation. I learnt this from reading about film and photo paper stability when silver photography was the norm.

Synthetics vs natural fibres - odour
Thanks Ghideon, will have a read.

Synthetics vs natural fibres - odour
I wonder if it's down to personal body chemistry then ?
-
Synthetics vs natural fibres - odour
I've been wondering why synthetic-fibre clothes encourage odour-causing bacterial activity yet natural fibres less so. Is it because synthetics are warmer, owing to being hydrophobic? I would have thought hygroscopic materials would provide a more amenable environment for smelly bacteria, with holding more moisture.

Increase tall
You are 3 inches closer than I am... I have 7 inches to go. You are 6ft, you can pull a 6'3" lady if that is what you like, without any bodily manipulation. It's an issue of your own construction because you don't want to really try. imo

How did we come from nowhere?
AFAIK, Any matter, like the quantum foam, which has components less than a quantum of energy has no effect on standard model particles, so energetically it's nothing. It's the lowest level of existence.

Updated to latest forum software
Looks like you need someone with an iPad. Just checked on my Android phone and the grey circle with a heart in it is there and I can choose to vote up and down. If you have an iPhone, have a look on that and if it's the same as the iPad, it's probably an Apple software issue.

Increase tall
The OP is nearly 6' 3" and I'm 5' 8"... PLEEEASE HELP ME!!! Where can I find some 7" booster shoes? Seriously, at the height the OP is, what proportion of women is he excluded from because he's "too short"? If I had the hots for a 2m woman and I had competition from a 2m man, I would still have a go because height may not be on her list of top priorities. The only way to find out is to try.

Looking for vaccine research…
Pope Francis said it well recently: "“I believe that ethically everyone should take the vaccine,” the Pope said in an interview with TV station Canale 5. “It is an ethical choice because you are gambling with your health, with your life, but you are also gambling with the lives of others.” Anti-vaxxers are about "me" and not "us".

Examples of Awesome, Unexpected Beauty in Nature
The cold in the lower US right now is springing up some unexpected ice art:

Eternal universe (split from Universe expanding...)
One is based on consensus of many learned minds, with much math and observation, and the other is a WAG from yourself. You know the forum rules on posting in the proper science sections.

Eternal universe (split from Universe expanding...)
This is not the speculation section
-
Universe expanding...
The 'centre' is wherever the observer is, and every other galaxy not gravitationally bound to their galaxy moves away. The apparent velocity they move away at increases with distance and causes an increasing redshift.
