You can't actually go though black holes, they just suck you in and compress you into a point.

We should've used Project Orion.
Which was actually practical. You use surplus nuclear weapons and starship/human waste to propel the ship to 1/10 or 1/50 or something of the speed of light.
Except the crew would be subject to ridiculous concussive, recurring G-force. Not to mention they would be exposed to unsurvivable amounts of radiation even with radiation shielding.

Probably a bump, but I was gone.
Well, a star may not actually be necessary

as says the article:
The crux of their idea involves using using a laser to form a micro black hole, which could be used as an energy source. This would be a Schwarzschild, or non-rotating, black hole which outputs Hawking Radiation, and the smaller the black hole, the more energetic.

Of course, making a black hole isn't the world's most easy undertaking. It takes a huge amount of power to build one in the first place. To make one of these mini black holes, Crane and Westmoreland propose a 370km2 solar panel, at an orbit one million km from the surface of the sun, which, if perfectly efficient, would gather enough energy per year to make one black hole. This power would be fed to a spherically converging gamma laser, with a lasing mass of around 10^9 tonnes. However, after you make a few black holes, you can use them as a power source to make more.
Well, as I said earlier it takes an extreme amount of mass to create one of these things. The issue is, even with the weight of the sun pushing down on the core it doesn't achieve black hole levels. You would need an incredible amount of pressure to create this in the first place, otherwise you would end up spawning supernovae. Really, the only way to create a small black hole is if a larger one loses its mass (due to hawking radiation) and ends up as a smaller one. One can't just spawn a small black hole.

However, Quantum Physics has a nice solution to our space travel problems. It's a cool thing called teleportation. Yeah, we have it working on earth. Small objects (as in smaller than an atom, sorry) have been teleported across seas before. Using quantum entanglement you can invert yourself at a new location, then be reinverted at that location to yield an exact copy of yourself at the new location.

how about you read the article instead of making batstuff assumptions from the title

Surely theyll be able to build a starship with a motherloving dense as stuff gravitational force RIGHT IN THEIR loving FACE

You are the loving people who stop the future from happening

ALL OF THIS IS POSSIBLE

No, it isn't. Well, it's at least highly improbable. There is no way we could harness enough energy to do what they're saying in the first place, then once we did we'd just have a black hole that we don't know what to do with.

The future of space travel is in quantum physics, not black holes.

"It isn't possible."

That's what they said about man being on the moon

That's what they said about airplanes or flight itself

That's what they said about cell phones

That's what the loving cave men said about fire

No, that's what handicaps said about a man being on the moon. That's what handicaps said about airplanes or flight itself, that's what handicaps said about cell phones, cavemen didn't have advanced enough language to propegate such a point.

The reason all these achievements have happened is because they're possible by utilizing our understanding of physics. Prior to putting a man on the moon, things had been projected into space. It was known that a man could be placed in space, and it's just a step of logic further to put a man on the moon.

Throw a thin piece of paper. Throw a model airplane. Look at a bird. Things fly. It happens. If you scale up the wings obviously it's going to be able to lift a human.

Radio waves have been used for a while before cellphones existed. Radios were pretty much stuff cellphones. I'm pretty sure most people didn't doubt that cellphones could exist.

On the other hand, our current understanding of astrophysics doesn't allow this to happen. Black holes simply can not be created at the size they are asking for. And even if they were, they wouldn't be able to be contained. That's just what a black hole is. It's not even debatable, you can't house a black hole because it will have a greater gravitational pull than the earth on whatever your housing is, and they don't defy gravity. It will be sucked down into the earth. There's a very scientific reason why this won't happen. The others have no scientific reasons why they wouldn't work.

Get it right.

Even if this was possible, not sure how happy I'd be to be in a vehicle with a black hole in the middle of it. What if it malfunctioned?

And stuff, that technology could be potentially abused, couldn't it?

No technology that has ever been developed has been free from potential abuse

that's such a silly thing to say

Rhetorical, Boltster. Making a point.
