According to the paper, this
hyperdrive motor would propel a craft through another dimension at
enormous speeds. It could leave Earth at lunchtime and get to the moon
in time for dinner. There's just one catch: the idea relies on an
obscure and largely unrecognised kind of physics. Can they possibly be
serious?
. . .
But can the hyperdrive really get off the ground?

The answer to that question hinges on the work of a little-known
German physicist. Burkhard Heim began to explore the hyperdrive
propulsion concept in the 1950s as a spin-off from his attempts to
heal the biggest divide in physics: the rift between quantum mechanics
and Einstein's general theory of relativity.
. . .

If you believe in visitors from other planets, you have to believe that
there is some type of hyperdrive, or something like that out there.
Otherwise, the whole alien thing is not doable.

Are we on the edge of having that technology revealed? On that, I would
have doubts.

On the other hand, if not now, when?
