A Wayne Question: Are Our Scientists Wrong? –
By Wayne Halm –
Sally is out of town and the golf course is wet – so this post is about my other passion – Astronomy.
Over the years Scientists have said some things that just don’t make sense to me. Are they wrong – or just bad communicators?
This post deals with one aspect of that question?
Scientists have told me that the spectrum of light coming from distant galaxies is shifted toward the red end. This is called “red shift” and means that the more distant galaxies are moving away from us.
I recall reading an article containing an illustration of the light from a nearby galaxy compared to the light from a galaxy nine billion light years away – it definitely demonstrated the red shift. The conclusion reached was that the more distant galaxy is moving away from us.
A light year is the distance light travels in one year (about six trillion miles) and it took nine billion years for the light from that distant galaxy to reach us. Nine billion years is a long time – a time that seems to have been ignored.
How does the above mean that the distant galaxy “is” moving away from us today, rather than it “was” moving away from us nine billion years ago?
Why Should You Care?
The “is / was” question is more than Wayne playing with words. A great many taxpayer funded research dollars go into “IS based projects”. I want some assurance the money is being spent wisely.
