Warp Theorists Say We've Entered an Exotic Propulsion Space Race to Build the World's First Working Warp Drive
The Debrief, 27 Jun 2024
An international team of physicists behind several revolutionary warp
drive concepts, including the first to require no exotic matter, says
that recent unprecedented breakthroughs in physics and propulsion have launched the world powers into a Cold War-style, 21st-century space
race to build the world's first working warp drive.

My opinion - Yes, we need better propulsion for space travel.
But NO, we do not necessarily need to go faster than
the Speed of Light. That feat, may indeed be impossible.
But slower than the speed of light still allows great
human exploration.

I think it is just incredible what we are doing with
robot machines and artificial intelligence in
our exploring on Mars. Flying a helicopter!!

This is the enabling technology for stable self-balancing flight: https://en.wikipedia.org/wiki/Vibrating_structure_gyroscope
I worked on a redesign of the Segway "gyro" which uses miniature motion and gravity sensor modules. https://segwaynz.wordpress.com/2012/01/30/segway-gyroscope-silicon-sensing-keeps-pt-in-balance/

The "Kettering Bug" drone of WW1 had a gyroscopic inertial guidance system designed by Elmer Sperry.

Torpedos have a similar 2 dimensional guidance control to keep them on
course, which in WW2 was automatically set by a sophisticated electromechanical computer.

Then you're in luck. The initial warp drives will likely be sub-light.
The FTL version so far is only "just" possible using bags of energy
and exotic matter.

But the universe managed to go from 0 to 100 bn light years in only 14 bn y
so at least we have something to aim for because "anture did it first". ;)

Humanity Uplifted: Poul Anderson's Brain Wave

The premise is this: something happens to cause, all over the world,
both people and animals to become smarter. Ordinary people become
geniuses.
[The story starts with a rabbit caught in a trap somehow reasoning how
to get out. During the last million years the earth has been in a zone
of space that negatively impacts thinking. Having evolved normal
intelligence even with this burden, after the earth suddenly passes
out of the region humans find themselves (probably) the smartest
people in the galaxy. Reality is, of course, somewhat different.
Ask anyone from Neptune ;)].

Sorry!! When did we determine that The Universe was '100 bn light years' across??

The speed limit is for thing travelling through space. NOT for space itself. Going faster than light would imply manipulating the geometry of
space-time locally in a controlled manner.

You can't just say that the universe is 100 billion light year across.
We don't know the actual size of the universe. We may never know. It may
be impossible to know.
