Now really think about this,, we know from scientific observation about 90% of the mass of the universe is not visible to us.
So, could the "dark" matter that makes up that mass have the same (if not more) complexity and diversity as the matter we can percieve.
Thus making up a larger,,,greater universe within our universe. Which is in reality the spirit world,, heaven, hell,, whatever myth you currently subscribe to.

Thoughtfull answers please.

Around Grants Pass Ore, Porcupines were once so plentiful that there was a bounty on them in the 1970's (50 cents a nose if I recall correctly) . Now most of the many local people I have asked have not seen a porcupine for 10-15 years. I am sure the bounty didn't kill them off, so what is happening. The only changes to their environment I know of is turkeys being introduced and a large influx of elk. So what gives? Have porcupines evolved camoflage, did some porcupine disease kill them, or... is something sinister going on.

I thought light particles contain limitless energy, and if is brought to a complete halt, they would explode, which obviously is not very correct, as nothing can contain limitless energy in the universe. Besides, light particles, or waves whatever the version of interpretation it is, travelling horrendously fast get absorbed by material things in their way soon as they come to touch with them. This happens way too calmly and smoothly causing just a little rise in temperature. Where does then all that energy go?

3^(6) - 1^(6) = 12^(3) - 10^(3)
i.e. a^(2n) - b^(2n) = c^(n) - d^(n)
give more examples like this if a & b is not having any common factor between them & n is an odd prime number.

A 537 g block starts at rest on a slope 4.7 m up (the highest point) and slides down a frictionless track. It leaves the track at 2.2 m high (where the track becomes horizontal), & then flies thru the air & subseqently strikes the ground. Acceleration of gravity is 9.81 m/s^2.

1. What is the speed (v) of the block when it leave the track, in units of m/s?

2. What is the horizontal distance (x) from when the block leaves the track, travels thru the air & hits the ground of the block, in units of m?

3. What is the speed of the block when it hits the ground, in units of m/s?
