Is everything in the Universe the same age?

You say lights travel is finite? I learned it traveled at 186,000 mi. per second, I know we’re splitting hairs here but I like to use that distance for calculation purposes. Beautiful picture of the deep field. Kind of cool when you think in terms of how long ago that light left to reach our eye. Who knows where the dust that makes up our planet was way back then. Mind boggling

Thank you for your work, more than enjoyable
