If we have a ship travelling a 10% C or about 108 Million km/h a marble would be catastrophic if the ship ran into it.
Bending Spacetime seems to be the only practical solution, and by practical I mean could possibly need more energy than exists in the universe and could destroy wherever you are travelling.
With our current understanding it is a fair assumption to say that FTL travel by propulsion is impossible.
If you could manage to bend space or create wormholes there are still problems...
How do you navigate?
If you can Imagine it then it will be possible.. right?
Someday by someone or some species.. all a matter of
How does organic material survive outside a planets atmosphere? I have read mixed results with some of the radiation being beneficial to seeds.
I would say FTL travel will not be achieved by organic life forms due to the fact that the energy required would have to exceed the energy available for the mass to reach such an acceleration.
This would actually for lack of better words make something non existent to a physical reality.
Sucks to be a lame time traveller lol

The odds of flying into something increase the further you go. This is only applicable for propulsion based travel but you would be going in a straight line and I wouldn't trust going in a straight line for 4 billion light years.
Bending space around you avoids this issue but still leaves you with a lot of effort for possibly little or no gain. Keep trying and eventually you'll find someone out there but how many trips do you do before you are disillusioned by the emptiness of space?
100? 1000? A Million?
Even assuming that instant travel to anywhere in the universe is quick and easy. It could still be a billion years before you find something worthwhile.
its not that you need that much energy to create a worm hole. it's that (absent negative mass and energy) it would take that much or more to enlarge the wormhole to usable size. but you see; you don't need to create a wormhole in the first place. there are literally an infinite number of them available for free in every cubic meter of space. even solid objects like your body are permeated by an infinity of them.

I tend to believe that wormhole starship travel is not a viable method of interstellar travel --- because some scientist's claim --- that you would need the energy of a supernova, in order to create a wormhole. The vibrations from the starship --- as it enters the wormhole --- would cause the wormhole to collapse unto itself.
actually he thinks he has positive results. it's just that because of the extraordinary nature of the claim he wants an incontrovertable above sigma or else no one will try to replicate his work. he knows that. that is the only sense in which his claim could be considered inconclusive. it's the same thing with Dr Woodward's mach principle work. he knows not to go all crazy prematurely. he had trouble replicating his results reliably so he plods on improving and gathering more evidence. it's sound philosophy.

If by "encouraging" you mean inconclusive, yes.
He has already had encouraging preliminary results.
You might want to jump to somewhere around 18:00.
