Just need a small multi chamber dark matter reactor for a power plant. Four chambers. Each one control's and powers different major functions of the ship. Why dark matter you ask? The light always chases the dark.

Society as we know it will end before this round of human existence will get there unfortunately. Most likely causes of “the end” are a galactic event of some sort (ex asteroid) or a major change in the earths climate and surface composition. Thats if we dont all kill ourselves first.

We could have had the ability to fly around the solar system in days or weeks by the 70's if we had embraced nuclear pulsed propulsion ala Project Orion. But the big babies who worried about setting off thousands of nuclear explosions in the Earth's atmosphere nixed it.

We could still build an Orion spacecraft today. Those things would be the size and weight of battleships.

"A nuclear pulse drive starship powered by fusion-antimatter catalyzed nuclear pulse propulsion units would be similarly in the 10% range and pure Matter-antimatter annihilation rockets would be theoretically capable of obtaining a velocity between 50% to 80% of the speed of light. In each case saving fuel for slowing down halves the maximum speed.At 0.1c, Orion thermonuclear starships would require a flight time of at least 44 years to reach Alpha Centauri, not counting time needed to reach that speed (about 36 days at constant acceleration of 1g or 9.8 m/s2). At 0.1c, an Orion starship would require 100 years to travel 10 light years. The astronomer Carl Sagan suggested that this would be an excellent use for current stockpiles of nuclear weapons."

Well, I’m glad you didn’t mean the weird gate thing they blew up the moon and half the planet with 😂

I haven’t been following the news on NASA’s nuclear rocket thing, but it sounds promising… either way it’s going to be waaaay less than 400 years

Pretty much. The Earth-Mars transit would be 2-5 days, depends on planetary alignment, and also how close your ship can get to the Sun without overheating.

For Pluto it's about 18 days.

The simplified equation to calculate travel time is 2 × sqrt(distance / acceleration)

The climate catastrophe we are building up will destroy us and hinder any progress towards space exploration. We should focus on that first.

Cowboy Bebop has hyperspace travel ("astral gate"). It's not clear if it's FTL, but if it is, I'm pretty confident it would never happen.

That's an interesting thought! Have you read any studies or research about what sound waves would do in a different atmosphere?

Never. Solar Systems will be established, there will be travel, communication, and trade within those systems, but space is too big for a civilization like we have on earth. Travel between systems will take thousands of years, so there will be local systems, but flying around the galaxy all Willy Nilly will probably never happen. This is all if we don’t destroy ourselves. But hopefully I’m wrong and some wicked technology comes around that is economically efficient enough to allow the traversal of long distances similar to what airplanes do, but idk seems far fetched.

Cowboy Bebop is only within our solar system, though.

It's nice to imagine it, however if there's no real functioning prototypes, speculating how long it'll take is moot. The space shuttle first launched 42 years ago. One would think that we've be closer to manned earthly space travel by now. Any advancements over 4 decades I would consider it to be fairly small. The cost gap is astronomical and a diminishing return for almost any company seeking immediate profit.

The sad truth is with the way we're going on this planet, we might never get there before the next mass extinction - except this one will be artificially created.

I'm not a pessimist, just trying to be real. Peace!

I don't fully understand your example. If you're just talking about small vehicles taking years to reach another solar system, then I think a launch like that could happen soon, like in the next century or two. There would have to be breakthroughs in propulsion. I'm talking about a vehicle with actual functionality, with GNC and comms to earth.

I think we will never be able to exceed the speed of light. It's just a fundamental hard reality of spacetime. So, for practical purposes, humans will never reach other star systems like in science fiction. Of course, there are ideas for generation ships that take decades or hundreds of years to reach other stars. I think something like that is far off, maybe never.

By the end of this century, much of the solar system will have been explored and have several colonies and outposts established.

Space travel gets much more difficult after you leave solar system. It's anybody's guess how long it will take to reach the nearest star.

I believe some humans on earth currently possess "UFO" type ships with antigravity. I don't think they will voluntarily share this tech... I think it will be after the real world war 3, after the human population is brought down significantly before that tech is shared with ALL of humanity, albeit a much smaller humanity. If you really think about it, humanity as it is, is too irresponsible for that tech.

All that said, I give it 200-400 years before bebop

I have it on good authority that the world will end on May 21, 2011. Harold Camping knows.

Hey OP, I read about the core reversal yesterday too and it's such an interesting phenomenon! But I do want to counter any misinformation: this is a normal, non-cataclysmic event that happens every 35-70 years.

The articles that I read say that the new study showed that the reversal might happen more like every 70 years, where some scientists thought previously it was every 35. The last time it did so prior to 2009 (on which this latest study was focused) was in the late 60s/early 70s, and besides some pretty spectacular music, there wasn't a cataclysm.

Here's some good non-sensationalized reporting on it:

Wouldn't mind the ETs appearing, though, that would be awesome! 😆
