Without knowing more about the universe, no one can say there is no completely empty spaces beyond where matter exists. We just cannot see that far.
Exactly, you can't change how long something is (besides cutting it) but the original length of something is absolute, just like time. Also...
Why couldn't there be other such localized areas, billions upon billions of light years away from another bigbang. There could have been billions of bigbangs all over the universe. We just can't see far enough to gather the appropriate information, and we need to do more than just see as well...
Just because we can't travel faster than the speed of light right now, doesn't mean we would never be able to. With that in mind, reaching the end of the observable universe would be possible, and to continue into the void where matter hasn't been yet would also be possible, although it would...
No boundaries. Why, because the universe is mostly nothing. Nothing only exists when there is a lack of something :P So you would eventually travel and reach the end of stuff and hit the void of nothingness, and continuing to travel further away from the nearest star, if you managed to get so...
Is there a formula to calculate how much force is released from compression springs knowing the exact specifications of the spring of course?
Like if it takes 100g to compress a spring completely, how high would 50g travel when the spring is released.
well, here's the thing, i have an idea and would love to share with everyone, but until i physically test it I am not going to, but if anyone has any input on the subject i would love to hear it
