    Odds are better your brother's friend Brzgmhgr will borrow it to record onto cassette and never return it.

    Speaking of black holes, remember a couple years ago when the first direct image of a black hole was released?

    Well, last month a new image was released of that same black hole showing it in polarized light, allowing astronomers see, for the first time, a signature of a black hole's magnetic field.

    So as you might remember (but probably don't), several years back I posted about some intriguing research being done on the concept of a real-life warp drive, which could allow spacecraft to effectively* exceed the speed of light (a la Star Trek).

    Well, a couple of recent papers seem to bring that idea closer to feasibility by finding ways (mathematically) to create the required "warp bubble" without having to use negative energy.

    I'll let an expert explain what that means and why it's potentially important:

    Warp drives: Physicists give chances of faster–than–light space travel a boost



    *I use the word "effectively" because the spacecraft itself would not be traveling through space faster the speed of light, which according Einstein's general relativity is impossible. Rather the warp drive warps space itself, compressing the space in front of the vehicle and expanding the space behind it, thus shrinking the distance it has to travel to get to its destination.

    You hop onto the HOV (High Occupancy Vulcan) lane.
