Its a possibility! Your loved ones, celebrities, etc. who died on this earth go to another planet-like earth to finish living out their lives that they couldn't while here. Its been said there's an after-life. Keep in mind that religion doesn't fit in with this quesion.

Last month they replaced my microwave, and in it was a metal or metallic rack, and I had never seen this?

before, and I said to the guy who installed it "I thought you're not supposed to put metal in microwaves", and he said it was some kind of special mayerial. What is this? Is it really metal? (sure looks, feels, weighs, etc, like) Is it some kind of microwave
resistant metal? I am very curious/mellow.

26 Stones and 3 Scales?

I have 26 stones which are all identical, save one has a chunck of gold in the center and weighs slightly more than the rest.

I have 3 balances, each of which I can only use once.

How can I find the stone with the gold?

I saw the same question asked about 12 stones so I decided to kick things up a notch. You can actually do even more stones than 26.

Good luck!

Why Did We Evolve To Walk So Upright?

We've all seen the pictures - crawling monkey to hunched ape, to slouched neanderthal, to upright man.

I've been trying to walk with better posture for a couple of days, and it's actually quite uncomfortable.

If you're just a little bit slumped, it feels a bit easier on the body, and you have a lower centre of gravity - better for scrambling around quickly and for stability.

So where's the evolutionary advantage in standing completely upright?

How do we know that the Milky Way Galaxy is a Spiral Galaxy?

Since no one has been outside of our galaxy to take a picture of it, how do we know that our galaxy is a Spiral Galaxy? I mean we've been told it is but is there a scientific explanation for it being a spiral galaxy (I know there is an explanation and I've been having a hard time finding it - so what is it?)

Lightning strikes us every day, blasting us with huge amounts of energy. Where does that energy go?

Everyone knows energy cannot be created or destroyed. So when lightning hits, as it does with insane frequency, where the heck does the charge go?

Time & Space?

If we're looking back in time as we look out across the universe, further back the farther we look, then why can't we see the history of our galaxy or solar system formation? In other words, why can't we see our ancient light as well?

Can anyone give me a difinite answer as to what a black hole really is and functions of it?

Okay, I've heard theories of how black holes are dimensional gateways, or just rips in the space-time continuum that is kinda like a cut, it will heal in time and when it does, all the matter and energy it absorbed will be put out at one time. Sounds plausible, but still out there. I know they are formed by a star's gravity well collapsing in on itself, along with a few other factors, but for want of space in this website, i have to cut them out. If anyone has theories of their own, I'd like to hear them, and if you have facts, bring those too. We really need to quit worrying about shuttles and start getting ships that carry people on exploration. Ships that go out to saturn, not to colonize, but to scan and search, ships that don't return to earth's surface, but get supplies from the space station after we ship them up. I know it costs a lot of money, but it would help answer questions like this one. Not to mention a boost in technology created by need of better systems devices.

Does the Space Shuttle have to turn to keep a camera pointed at Earth as it orbits?

The Moon always keeps one face towards Earth which means it rotates once on its axis for each orbit. Moons around other planets don't necessarily do the same. If you are on the Space Shuttle and are trying to take a video of the Earth, will you automatically keep pointing at the Earth or do you have to turn the Shuttle as you orbit?
