(PhysOrg.com) -- A renowned expert on helium says we are wasting our supplies of the inert gas helium and will run out within 25 to 30 years, which will have disastrous consequences for hospitals and industry.
Come on, admit it, you've had this question. "Since astronomers know that the Universe is expanding, what's it expanding into? What's outside of the Universe?" Ask any astronomer and you'll get an unsatisfying answer. We ...

(PhysOrg.com) -- How hard can it be to lift a house with helium balloons? A National Geographic team of scientists, engineers, and balloon pilots has demonstrated how to achieve such a feat, which was filmed for a new TV ...
One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. Instead, quantum physics ...

A balloon is an inflatable flexible bag filled with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern balloons can be made from materials such as rubber, latex, polychloroprene, or a nylon fabric, while some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications. The inventor of the rubber balloon, (the most common balloon) was Michael Faraday in 1824, via experiments with various gases.
