I recently bit the bullet and replaced my hard drive (actually I was forced to as the old one failed) I bought a (£70) SSD and installed everything I really need from fresh - it took a few days to straighten it all out what with updates etc - I even went Win 10, why not? All seems to be working fine as before except a lot faster! PS I also gave it a good clean out, the desktop is kept at floor level and sure does accumulate dust inside - I took off the CPU fan to clean it as the heatsink was literally solid with dust...

I had almost the exact same experience. The old HDD never failed, I just ran out of space on the system partition. Anyway, it was a great excuse to finally get a SSD especially since the price to capacity ratio is now reasonable. ($200/480GB for mine) I also went with 10 and really like it so far.
As for the dust, originally when I rebuilt, I just did a light dusting. Not long after getting 10 up and running, I tried out Minecraft, liked it, and bought it. The problem was after 10 minutes or so of playing, the system would just shut down. My suspicion of overheating was confirmed when I installed a hardware monitor that showed CPU temps of 270F! A thorough cleaning did the trick. The temps now never break 150F and it's much quieter! It's amazing how over the years, you just get used to the fan noise.

Just thought-experimenting.
If (as often happens) we represent 'spacetime' as a flat sheet (usually black rubber with white grid lines) and the distortion of spacetime by mass as a large ball sitting on the sheet, we can show the effect of gravity by rolling a smaller ball along the sheet, which will accelerate toward the large ball, and (ignoring friction) collide with or orbit.
So far so good.
In this model the flat sheet is suspended in 'nothing'.
But, what if you 'zoomed out' and the sheet was actually curved? Imagine it is sitting on a massive sphere.
If the sphere grows, so the 'universe' will expand.
Indeed if the sheet itself were like the skin of a massive rubber ball, then this effect would be observed if the ball was inflated.
So what we call 'dark energy' could simply be the inflation of whatever it is that 'supports' the universe.

Human mind was created to enable us to survive on earth. To find food and mate for reproduction.
Explaining a concept beyond 3 dimensional space as "curved" is still using 3 dimensional concept.
God doesn't owe us a "how" answer in human words. Our brains are not ready.

This is like a fish trying understand gravity. Maybe the fish would imagine it as constant invisible water flowing downwards. Because the fish brain is created so it can understand and survive underwater environment it does not have the brain pathway to understand dry land.

Because I don't have the language to describe curving through a 4th dimension, not beause something cannot. Think of it as an analogy.

A curve requires 2 dimensions.
You could plot a curve across the x and y, or y and z, etc
If you read only a single axis coordinates (for instance assign all x values the same and read a curve's Y, it is indistinguishable from a line)
A curve involving the 4th dimension is this:
An object accelerating in a straight line.
Translate axis where X is the distance travelled and y,z =0
Time is experienced differently as it speeds thus the 4th dimension and curve
If you ignore the relativity changes in time, all you see is the straight ray on axis X

You think you can't curve in 3 dimensions? Wow - how the heck did we ever get to the moon?!
Time is not the 4th dimension in question here. Time isn't really a dimension at all, except in sci fi movies and '4D Cinemas'

The earth/moon system is speeding around the sun at hundreds of thousands of km/h.
The speed and precision required to reach the moon without the earth/moon system disappearing into the distance must have been remarkable.

Yes!
It's exactly the same precision that's involved in putting a cup down on a table without breaking the table, the cup, or your hand!

Be nice. Calculus isn't included in computing courses.

Neither is x, y and z - they're just convenient mathematical abstractions ... just like r, θ and φ

So does light travel in a ray or does it not
|
|
|
|
|
Yes it doesn't. Or no it does. It's definitely one of those.
I am not a number. I am a ... no, wait!

But a ray cannot deviate from a straight line. Light however can bend due to gravity. Someone has been lying but the question is who.

Says who? If that's your a priori definition of ray then light doesn't travel in one. No contradiction. No lying.

I can prove it does deviate with a simple mirror, or prism... 
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

There we have it!
Everyone take heed, because CP's expert on deviation hath spake.
