Pros and Cons of Various Methods of Interstellar Travel
universetoday.com ^ | Matt Williams

Posted on 05/14/2018 11:08:12 PM PDT by BenLurkin

It’s a staple of science fiction.... the idea of sending out spaceships with colonists and transplanting the seed of humanity among the stars. Between discovering new worlds, becoming an interstellar species, and maybe even finding extra-terrestrial civilizations, the dream of spreading beyond the Solar System is one that can’t become reality soon enough!

For decades, scientists have contemplated how humanity might one-day reach achieve this lofty goal. And the range of concepts they have come up with present a whole lot of pros and cons. These pros and cons were raised in a recent study by Martin Braddock, a member of the Mansfield and Sutton Astronomical Society, a Fellow of the Royal Society of Biology, and a Fellow of the Royal Astronomical Society.

The study, titled “Concepts for Deep Space Travel: From Warp Drives and Hibernation to World Ships and Cryogenics“, recently appeared in the scientific journal Current Trends in Biomedical Engineering and Biosciences (a Juniper Journals publication). As Braddock indicates in his study, the question of how human beings could explore neighboring star systems has become more relevant in recent years thanks to exoplanet discoveries.

All told, Dr. Braddock considers five principle means for mounting crewed missions to other star systems in his study. These include super-luminal (aka/ FTL) travel, hibernation or stasis regimes, negligible senescence (aka. anti-aging) engineering, world ships capable of supporting multiple generations of travellers (aka. generation ships), and cyogenic freezing technologies.

For FTL travel, the advantages are obvious, and while it remains entirely theoretical at this point, there are concepts being investigated today. A notable FTL concept – known as the Alcubierre Warp Drive – is currently being researched by multiple organizations, which includes the Tau Zero Foundation and the Advanced Propulsion Physics Laboratory: Eagleworks (APPL:E) at NASA’s Johnson Space Center.

Dimensions are not places where you can go. There is no “fourth dimension” you can slip into to avoid the laws of physics.

Flux capacitor as a power source would do the trick.

"There is no “fourth dimension” you can slip into to avoid the laws of physics."

Time itself is a forth dimension (although, possibly more accurately identified as the 'zeroth' dimension).

Another “Scientific” idea that makes Infinity Wars look like a documentary.

Man make take some time, but some ‘from the mouths of babes’ will noodle out a ‘solution’

But to think Man knows all of what is possible to say “NEVER!” is the epitome of hubris and ignorance.

I don’t think that physicists, who are madly seeking undetectable phenomena, are going to solve the FTL problem.

The only realistic approach I see is where a new planet is formed in our solar system, between Mars and Earth.

world ships capable of supporting multiple generations of travellers (aka. generation ships),

Fine for the first generation of trained crew eager to leave Earth, but what happens when a quarter of the crew are three-foot tall entropy monsters. "You let go of the airlock knob. Let it go! You'll get a spanking if you turn that an no one will hear you scream."

the only way meaningful space travel could be possible would be to slip in and out of another dimension where time does not exist

Time does not exist. Time is a construct of the human mind based on observations of movements of heavenly bodies.

It would suck to be an early star explorer, get there after many years and tribulations, only to discover people with newer tech beat you there.

But there is a 5th Dimension And they already figured out how to travel in space.

You don't understand what I posted, and have made yourself look like a fool in your reply.

Take your idiotic metaphors up with Euclid. The geometry of spacetime is what it is, and it isn't a lack of vision of engineering.

Like the idea that a baseball could quantum mechanically tunnel through a mountain because it’s “theoretically possible” (read: impossible in every practical sense) these ideas are genuinely preposterous.

Well at about four and a quarter light years from Earth a trip to Alpha Centuari is around....(my math is not so good) 800 million light years? So, the travelers will be kind of ... old.

“Only thing needed is an engine with constant acceleration of, say, a tolerable 1.1g”

How would you fuel such an engine?

The limitlessness of human knowledge and INNOVATION ‘is what it is’

But, if you say so, Stephen Hawking *rolls eyes*

As Heinlein noted, settling the Solar System will be like any of Earth’s Great Migrations, “The cowards never started, and the weaklings died on the way.”
