Uh...yeah, two minutes from rest to 37,000 mph. Let’s just say that’s a lot of acceleration and leave it at that. May have to be a few advances in materials technology before that’s going to happen.

“Just plug in the numbers for those understand weight, velocity and energy. This is total crap science not worthy of discussion.”
I don’t think it even rises to that level. It’s not even good science fiction. At least science fiction comes up with novel ideas that allow the conventional rules to be broken or bent.
The g-forces alone would disintegrate any physical object accelerated at such a rate. At one g, it would take several weeks to reach one fifth of the speed of light. Doing so in a few seconds simply can not be done with any technology known today. The object being accelerated would be destroyed down to the cellular level.
Even if this could be achieved by a less rapid acceleration over a few months, there will be no way to slow the object down. How does photography work at 0.2 c?

> "The team behind Breakthrough Starshot is as
impressive as the technology. The board of directors includes Milner, Hawking, and Facebook co-founder Mark Zuckerberg. The executive director is S. Pete Worden, former director of NASA Ames Research Center. A number of prominent scientists, including Nobel and Breakthrough Laureates, are serving as advisors to the project, and Milner has promised $100 million of his own funds to begin work."
Milner? Don't know much about Milner but he appears to be the money guy.
Hawking? He's dead, Jim.
Suckerberg? Impressive? Are you kidding?
Worden? Was he one of those that made NASA's mission to be an outreach to Muslims?

"two minutes from rest to 37,000 mph" No. They're claiming 37,000 miles per second, not per hour.

"Any information gathered by telemetry will be for future generations... Who wont give a shite." Given the state of Europe, and the fierce battle we are fighting in America, it may be that the future won't look even as good as the Planet of the Apes, but instead the world will be ruled by those with a lower IQ than even the late Koko.

a thousand times faster than any macroscopic object has ever achieved. Forgot to add this, no macroscopic object launched from earth has ever achieved even a fraction of this speed.
I hate Crap Science. Some fools read this crap science and believe it.
The energy required to accelerate just a few grams to these velocities is beyond our ability. We are talking megatons of energy over a few seconds. That is one hell of laser and I do not want to be 1000 miles from it when they pull the trigger. The sail would need to 100 percent reflective as just a minuscule percentage of the energy not reflected would instantaneously render it plasma and perhaps atomic particles.
I hate Crap Science being published as science. Those that do are not persons of science.

No. They're claiming 37,000 miles per second, not per hour. Augh! You are, of course, correct. That's only 2,200,000 mph. Don Garlits vs. Shirley Muldowney at the NHRA finals...

1.21 gigawatts to be exact
I've heard rumors that Dr.Brown has recently been added to the team - so this is looking more and more like a real project!

Correction: 37,000 miles per
second That much speed differential over a period of 120 seconds requires an average acceleration of about 51,000 G. It is possible for specially constructed electronics to survive G forces in that region.
That speed would make the flyby portion come and go in seconds. There would be measurable relativistic time dilation, but it would not be a deal-breaker.

The solution is warping space time where a line becomes a point. All that needs doing is the implementation.

I wish I was 40 years younger. the incredible thing coming in the future. imagine being alive when the first video from a space craft traveling to another star system is received on planet earth. imagine a tourist trip to the moon. unfortunately I am sure I wont be around for any of this but the little boy in me wants to be there.

"A day will come when some whiz kid cracks the code that enables faster than light travel"
I tend to disagree with that, in the sense that there was no dark age of physics. No one has successfully broken any law of physics--there have only been modifications to it, such as Einstein's modifications to Newton's laws of gravity. I personally don't think the speed of light can ever be exceeded, no more than you can travel backwards in time. Both concepts produce paradoxes which cannot be resolved.
