We've heard rumblings that Samsung's Exhibit 4G would be making its way to T-Mob on June 8, but now the carrier has confirmed that the Gingerbread smartphone will be available sometime in June. The Exhibit will join Samsung's Gravity Smart, both featuring grounded sub-$100 price tags (after $50 rebate) when they hit stores. T-Mob is displaying the Exhibit with violet and black finishes, and says you'll see "theoretical" peak download speeds of 21Mbps on the HSPA + handset. As for the Smart, the carrier's first Android-powered Gravity smartphone will launch with 2.2 Froyo, and includes a slide-out QWERTY keyboard, so you'll be sending Group Texts to 50 of your closest friends with four rows of hardware keys. Both phones include 3 megapixel rear-facing cameras with flashes, while the Exhibit adds a front-facing cam as well, so that myTouch 4G girl may be hawking a new smartphone on your TV later this month.

Well, it looks like Einstein knew what he was talking about, after all. Earlier this week, researchers atNASA and Stanford released the findings from their six-year Gravity Probe B (GP-B) mission, launched to test Einstein's general theory of relativity. To do so, engineers strapped the GP-B satellite with four ultra-precise  gyroscopes to measure two pillars of the theory: the geodetic effect (the bending of space and time around a gravitational body) and frame dragging (the extent to which rotating bodies drag space and time with them as they spin on their axes). As they circled the Earth in polar orbit, the GP-B's gyroscopes were pointed squarely at the IM Pegasi guide star, while engineers observed their behavior. In the universe outlined by Einstein's theories, space and time are interwoven to create a four-dimensional web, atop which the Earth and other planetary bodies sit. The Earth's mass, he argued, creates a vortex in this web, implying that all objects orb...
