If the Big Bang was an explosion and everything in the universe is accelerating outward from that original point, then how do planets orbit? For one half of the orbit the planet is moving in the direction that it was projected at in the explosion, however, the other half of the orbit is moving in the direction of the explosion which obviously violates the laws of physics.

This summer, all the bumble bees we've seen around our yard have been unusually huge. And all of them have been having big problems flying. They look drunk. They'll get a tiny bit above the ground and then fall back down again. They'll try again and flip over. We've seen about ten like this and are beginning to wonder if there's something wrong with them. They're all coming from a a hole in our landlord's shed. Has anyone ever seen bees like this? Is it normal?

I've heard that NASA has actually managed to get a form of a hyperspace window open but can't keep it open long enough to really do anything useful. Is this really true, and how would it work?

Hello!
I have an unknown compound of simple salt that contains one cation and one anion. Possible cations include silver, lead, bismuth, tin, aluminum, zinc and antimony. Possible anions include chloride, bromide, Iodine, sulfate, sulfide, sulfite, nitrate, phosphate, and colbalt. I try to dissolve the unknown compound into the following solution.

In H2O: insoluble even with stirring and heating
In HCl: insoluble after stirring and heating
In HNO3: soluble after stirring and heating
In NaOH: soluble after upon adding into 6 M NaOH
IN NH3: soluble after adding, and complete soluble after stir and wait.

I think it's silver chloride. Any idea?

Many years ago I remember reading in an old science year book, about a lake that contained a lot of sulfuric acid, or some other type of acid. I believe there was even an aeriel photo of the lake, with a small metal canoe on it, and the water appeared to be a rainbow of colors, reds and oranges near the shoreline, and green and deep blue in hte center. It was surrounded by barren rock formations. Does this place actually exist? I read a lot of those science year books when I was younger.... not sure if I am putting together different information or not. Thanks!

Einstein said light waves actually bend the closer you get to a large object. It could be that a distant star's light (and its other radiation) bends as it crosses the all those billions of galaxies with the trillions of other suns. What we end up seeing in the night sky may be ricocheted and distorted reflections of a star's image. Scientists may be basing conclusions on distorted data. What do you think?
