calculating the age of the universe is like pinpointing the position of an atom, by the time you thought you knew it's position it already changed? perhaps it's not the universe that's expanding, but our own imagination that it is expanding so we develop the tools to design what we want to see?

I think farscape and startrek voyager are much better in trying to explain scientific concepts

I watched that movie twice, lots of the science seem possible. I don't quiet understand your question though, and even confuse why the water is so shallow on that planet yet the tidal wave could be so huge. beside, a spaceship could withstand gravitational force, yet cannot withstand tidal...

I've been wondering why so many wants to go into other planets when we still have so much to do to improve Earth and our own part of the universe. why not a story about building Earth in your vision, then we have nine more planets in our solar system to your world-building imagination, plus...

it's sci-fi, does it has to be correct? it's about imagination more than reality?

very confused now, so how big is the universe now in 2015 Earth year?

the center of the universe is where you're at, because you're measuring from there to whatever you want.

Dear Calculus, I don't want to do differentiation I don't want to do integration I want to be multicultural

if i have a ruler that measure 1m on a flat surface, if i bend it to measure a ball, the 1m does not change. or i lay a grid system with many perfect squares of each side being 1m on a flat surface, the length of the sides on these perfect squares will change their sides other than 1m each?

i think it's a hypothesis. a theory needs to be proven, how can you know it exist if you didn't exist?

thanks for sharing your shop experience, i just didn't realize that in our physical world that machines parts would need to be in the third digits or more after the decimal ...but good to know :) the video of the si-28 sphere is interesting :)

could you please elaborate your version of "pi" ? much appreciate the knowledge i could gain from you :)

thanks everyone for helping :) so even if the radius of sphere transforms pi (22/7) into a perfect number, i won't get a perfect sphere? if the radius is 3500 km, the surface area would be 154,000,000 km2...these could be perfect square each measuring 1km on each of its four sides? so if i...

but how do you create one?

the formula for the surface area of a sphere is SA = 4 (pi) r2, with pi = 22/7 and r = radius of the sphere. for example the SA for Earth with a radius of 6,378 km is 510,065,600 km2 what would the radius be in order that for you to lay a grid of perfect square on the surface of the sphere?
