    A single atom of gold is far too small for any photon in the visible spectrum to interact with.

    A single atom of gold is 0.2 nanometres (a nanometre is an incredibly small thing and a gold atom isn’t even half of 1% of that), meanwhile the wavelength of blue light (The smallest wavelength of visible light) is a hulking 380 nanometres. No matter how much you zoom in you would never see anything a single atom is just too small to interact with light.











  • They’re talking about stretching out the whole ageing process. So if you live longer you also grow old more slowly.

    Rats average lifespan is 3 years, but that doesn’t mean they are really healthy, and then just drop dead, they go through the ageing process at a hyper-accelerated rate. Equally if humans had a lifespan of 120 years the old age part would move to around the 100 years mark, you wouldn’t start getting old at 60 and then just be geriatric for the next 60 years.
