Magellanic Stream arcing over Milky Way may be five times closer than previously thought

Our galaxy is not alone. Swirling around the Milky Way are several smaller, dwarf galaxies—the biggest of which are the Small and Large Magellanic Clouds, visible in the night sky of the Southern Hemisphere.

During their dance around the Milky Way over billions of years, the Magellanic Clouds’ gravity has ripped from each of them an enormous arc of gas—the Magellanic Stream. The stream helps tell the history of how the Milky Way and its closest galaxies came to be and what their future looks like.

New astronomical models developed by scientists at the University of Wisconsin–Madison and the Space Telescope Science Institute recreate the birth of the Magellanic Stream over the last 3.5 billion years. Using the latest data on the structure of the gas, the researchers discovered that the stream may be five times closer to Earth than previously thought.

A Futuristic Mobile Home Can Crawl Its Way Across Nearly All Surfaces

The design is a cubic frame on six mechanical legs that looks like it emerged from futuristic sci-fi movies. The mobile home is able to traverse on almost any terrain including steep hills and mountain gorges with its mechanical legs that are enhanced with 2 inches (5 cm) of non-slippery rubber layers and two deployable spikes on the bottom of each piece for easy bolting on the ground.

The mobile home can lay its foundation while remaining uplifted from the ground, descending, or sitting on the ground.

The mobile home’s interior design comes with high-tech elements inspired by a futuristic architectural perspective. The windows of the mobile home are equipped with smart glass technology that can block sunlight when needed. Enchev also used automated furniture and smart technological gadgets in his design. With its integrated storage space, water tanks, and power cells, the mobile home enables its residents to live off-grid comfortably.

Rare Einstein manuscript set to fetch millions

A rare manuscript by theoretical physicist Albert Einstein goes under the hammer in Paris on Tuesday, with auctioneers aiming for a stratospheric price tag.

The manuscript, containing preparatory work for Einstein’s key achievement the theory of relativity, is estimated at between two and three million euros (2.3−3.4 million), according to Christie’s which is hosting the sale on behalf of the Aguttes auction house.

“This is without a doubt the most valuable Einstein manuscript ever to come to auction,” Christie’s said in a statement.

‘Triple Leidenfrost effect’ seen in dissimilar drops in a hot pan

A small team of researchers from Benemérita Universidad and Universidad de las Américas Puebla, in Mexico and Université de Poitiers, in France, has found a “triple Leidenfrost effect” in dissimilar drops in a hot pan. In their paper published in the journal Physical Review Letters, the group describes a type of “bouncing” they observed with different types of drops hovering over a hot surface.

Prior research has shown that the reason drops of water zip around in a hot pan, is because water at the bottom of the drops is vaporized—thus, the drops hover like air-hockey pucks. This phenomenon has come to be known as the Leidenfrost effect. In this new effort, the researchers have found another behavior associated with the Leidenfrost effect.

The work involved dropping two types of liquid onto a hot surface and then tilting the surface to force the drops to run into each other. They wanted to know if the two drops would merge. Instead they found that sometimes one of the drops would start bouncing off of the other.

Einstein’s special theory of relativity combines space and time into one dynamic, unified entity — spacetime. But if time is connected to space, could the universe be anything but deterministic? And does that mean that the future is predestined?
