There is something about the timeline of the Big Bang theory that has been bothering me for the past month or so. If you are vaguely familiar with the widely accepted theory of how our universe (multiverse?) got its start, you will know that according to theory, a lot happened in the first second.
My problem is with relativity - I cannot find a good explanation anywhere what 1 second means? Surely the mass of the singularity had to be insanely large - much larger than a typical black hole. We know from Einstein's theory of relativity that gravitational time dilation occurs near heavy objects. So is 1 second in the Big Bang theory measured from within the expanding singularity? It surely cannot be outside of it as spacetime evolved from that singularity; speaking of space outside of the expanding singularity is just nonsensical. So the "observer" had to be squished inside the expanding singularity, meaning if 1 second was relative to that location, that 1 second would not be the same as 1 second we experience here on earth. Not true? It had to be an eternity. Time is relative, is it not?
We had an 86.9% solar eclipse just now, 21 August 2017. Not as cool as a total solar eclipse but I had the luxury of seeing it from my own back yard.
Just something I need to clear up before someone goes up in arms about my rants - in general many of these Youtubers and other reviewers produce acceptable content most of the time. It is just sometimes that they fall of the cliff edge like lemmings when they speak about a subject that they do not have sufficient expertise in, but claim they do.
Just like I would never try and teach other people how to put nitrous oxide in your car to make it go really fast (as I have no clue how to do that), people should stop proffering advice on topics they have inadequate knowledge of. When that happens and come across my way (and knowledge domain), I'll speak up.
For this one, please review the following five videos: Video 1/5, Video 2/5, Video 3/5, Video 4/5 and Video 5/5. Sorry, this is a very long one but there is a lot of content to go over. There is also one other, related video I'd like you to review - specifically where he speaks about the Mac Pro being the 2nd most overpriced tech.
Before reading my rant, first review the video in question from Marques Brownlee, considered the "best technology reviewer on the planet right now" in 2013.
His video is about the quality of onboard DAC/amplifiers on the sound card embedded with most motherboards inside of computers. Firstly, he refers to it as "Digital to Audio Converter". Just google it - that does not instil confidence. Secondly, he makes this very broad statement:
As a general rule people buy external Digital to Audio [sic] Converters because the internal ones that are built in to our computers that feed directly to the output headphones jack basically, are typically really really bad.
