So... If I drive fast enough to go and get my new water heater, it will already be installed by the time I get home. I better take the HEMI!
The Speed Of Light ??

That’s not certain, it may or it may not be. It’s expanding, so it may not be infinite.
Well if it isn't what could be at the "end".... And what is beyond that?
Well that’s not a question because it’s not a boundary into something else. Space is space, it expands but not into anything. It is what it is. There isn’t an existing empty space just waiting for space to expand into.
Not saying I can exactly grasp that myself either. I know it’s not a lot more satisfying than an infinite.
Space doesn’t expand into anything. It is the space.
Infinity is hard to comprehend.
Same as the speed of light. Just like hot and cold, chicken and egg, are both the same thing but human brains bin them into different category.
There is no spoon.
that's because it is incomprehensible.... like when you were young and learned to count to 10, then 20, then 100. Every time you reached what was the end of the counting scale for you, it wasn't and it never will be.
Nobody knows, and maybe we will not have the energy and technology to measure and come to a conclusion. So far everything is just an assumption until proven otherwise.
Infinity is just a symbol human use to simplify the math equation. There is no such thing in nature. Infinity is also the reason why many investors lose their shirts with the wrong models.
Me after trying reading and trying to comprehend it all. 
Infinity is a difficult thing to wrap your mind around.
It is just a symbol to be used for cancellation in math. Something like:
Infinite + a finite number = infinite, the finite number becomes very small that can be disregarded.
B keeps growing and will approach infinite eventually,
(2 x B) / (3 x B) = 2/3, the B that approaches infinite gets cancelled out.
In reality nobody really use infinite, just using it to cancel out all the small numbers when we know we are dealing with infinite and eventually come up with something that is non infinite, but a ratio between something.
It has always been hard for me to get my head around, but time is not absolute - it actually does slow down as you go faster.
This was theorized by Einstein early in the 20th century, and confirmed empirically decades later when very accurate atomic clocks were available.
In one very clever experiment, scientists synchronized several atomic clocks, kept the control clocks in the lab, and placed the others on jet airliners. The clocks on the airliners travelled much faster than the clocks in the lab, and recorded slightly less accumulated time.
The person on Earth with a telescope that could see the traveler in the spaceship heading away at speed of light would see that inside the people would look like they were in extreme slow motion.
Speed of light is a constant. Light out of a flashlight on ground = speed of light. Light out of flashlight on an airplane traveling 500 mph...also speed of light not speed of light + 500.
Thanks Einstein

Infinite is a funny thing. I remember in some class or another when the professor asked us how large is the set of odd integers. The answer is infinite, of course. Then he asked us how large is the set of all integers. Again, infinite. Yet one is clearly twice as large as the other, but both are infinitely large. So they are equally large.
You managed to stay awake for that ?
So, if I understand this right.....
If I work faster, my retirement date of Dec 2027 will get here faster?
And here I been doin' it all wrong for 40yrs!!

That's not how it should be interpreted.
The set of odd number integer is N, N approaches infinity.
The set of all number integer is 2N, since it is 2x of all the odd number integer, and 2N approaches infinity twice as fast.
Their relative to each other size are calculated with Lim N->infinity (2N / N) = Lim N->infinity (2) = 2.
This is how Calculus was invented. Eventually all the infinite is compared to each other and if you do it right, only the ratio remains and all the infinity cancel out, and all the non infinite added to infinite got rounded to zero eventually and discarded as well.
Very good, thank you. You know your stuff
Chemistry, physics, and math were my favorites
