The power to propel us to the stars

Can we reach the stars and beyond?

The answer is YES!!

Getting humans into outer space is not the problem. Humans have already walked on the moon. The problem with space travel is the vast distance between our solar system and the nearest one to us. The problem is in the speed needed to reach these far-off places in a reasonable time frame. The solution to the has been right in front of us.

Take for example someone at the front of a train traveling 100 MPH. If the person fires a bullet out ahead of the trail that travels at 300 MPH if you clocked the speed of this bullet it would clock at 400 MPH, not 300.

The same principle could be applied to space travel. The craft would have multiple propulsion engines. When the first one is fired it propels to craft to a speed of 1,000 MPH. When the second propulsion engine is fired (with the same propulsion force as the first), the craft is now traveling at a speed of 1,000+1,000 equaling a speed of 2,000 MPH.

If you continue firing these engines your speed increases with each engine burn. The ultimate speed you reach depends on how many propulsion bursts your engines can provide. One burst at a time you could reach the speed of light and beyond.

Or so it seemed~~~~~~~~

Now, some time later I discarded the above idea, a spacecraft could not contain enough fuel to propel us to distant stars.

Then an actual solution came to mind.

We use the force of gravity to pull us to wherever we want to go. Magnify the force of gravity using the gravity pull of galaxies channeling that pull in a narrow band multiply the pulling force of gravity exponentially to a limitless speed.getting us to where we want to go

You're talking about multi-stage rockets like the Saturn that lifted the Apollos. BTW, so far as we know, faster than light travel is impossible as is "channeling" gravity.

Gravity assist can work in the solar system with moving planets, but that's not good enough to get us out of the solar system with enough speed to reach the nearest star.

 

[MarathonMike]

Assuming gravity assist allows us to achieve mind boggling speeds, how do we slow down once we've arrived at our destination?

 

[Moonglow]

There needs to be a better rocket fuel than solid rocket fuel to save on weight ratios and resupply logistics.....

Many factors must be considered even before a means of propulsion is engineered to take us beyond our solar system and out into the interstellar winds. Among the most vital of those are artificial gravity systems and or hibernation chambers, effective hull shielding of any such hypothetical craft, hydroponics farms, navigation systems, powerplants and so many others including but not limited to means of interstellar communications. For in heliosphere propulsion one of our currently buildable best options might be the magnetic confinement fusion reactor used to heat and cool powerful magnets to create forward motion. But that wouldn't cut it for propelling us between the stars. For such an excursion, one possible place to look could be massive Halbach Arrays used somehow to bend time and space or open a wormhole to a distant solar system. But of course, that kind of tech, even if ultimately possible, is likely many years out. Fascinating conundrum to ponder nevertheless.

We just turn our gravity pulling dish towards another galaxy changing our direction?

While I am unable to remember where I read it, perhaps in a novel or a physics course, I once came by the very hypothetical theory of somehow "firing" a beam of light into a blackhole and using that connection as a tether of sorts to pull a spaceship toward said blackhole at massive speeds, as even light cannot escape the event horizon. My first thought? How would one "connect" such a beam of light to a space craft, and how many thousands or hundreds of thousands of years would it take for such a beam of light to reach the nearest black hole?

If gravity assist were that good, hypothetically, gravity assist in some distant solar system could be used as long as there are enough planets to gravitationally retard the motion. You would approach the planet from the opposite direction that it is moving relative to you.

There is no dish. Gravity assist is similar to the slingshot move in roller derbys, where a team mate pulls you forward. You gain momentum and she (mostly women) looses it.

Just dial up the planet you want to visit.

Problem solved.

Tiny spacecrafts powered by a powerful earth laser seems to be the only hope to reach a distant star.

Gravity is the weakest of the four fundamental forces.

 

[fncceo]

Magnify the force of gravity using the gravity pull of galaxies

Inverse square law of propagation prohibits this.

The galaxies are just too damn far away.

 

[watchingfromafar]

"gravity" is holding that galaxy
together--even as hard as it wants to fly apart

It's worse than that, Wu. In space, the pull of gravity is not only essentially equal in all directions, thereby being no "bias" upon which to propel you anywhere, not only is there no dish or lens to "focus" or direct gravity because gravity is a field rather than a force, but the gravity from the guy sitting beside you in the ship is far greater than the gravity from another galaxy.

Just another pointless "science" thread with no actual science in it.

Gravity assist does work.

The pull of gravity alone doesn't do anything. It's the motion of the planets that assists the propulsion. Gravity assist is commonly used for getting probes to the outer planets. It helps the probes gain speed and reduces fuel cost. Gravity assist is useful for planetary exploration but is way too small to get a spacecraft to a star system in a reasonable amount of time.

I know all about conventional gravity assist. That wasn't what the OP was referring to. Gravity assist works here in the solar system because you can isolate a deep gravity well to accelerate you to maybe 40-60Kmph. That might help getting to Pluto, but too fast and you can't get enough gravity assist to STOP you (land or go into orbit). My point was that once out of the solar system into deep space, there isn't anything you can plan on using to get you to the stars, and even if you could get close to 1C somehow on gravity assist alone, it would sill take you many years just to get to the nearest star.

Neither is ion propulsion, etc., much better where you spend half the trip accelerating then half the trip de-accelerating. Such ideas might be a rudimentary place to start from, but true space travel among the stars will require the ability to go faster, stop, turn, and be essentially a self-renewing power source.

The pessimism here of overwhelming. Mankind will travel the stars, it's just a matter of designing the technology to do it. With billions of suns, and billions of planets circling these suns the odds are totally in favor of there being star travelers out there and some may have visited earth at some point in the past and/or they will in the future.
How many planets do you believe are in this image-?
