Is it possible to use nuclear shaped charges like a casaba howizter to propell a colony ship around 30-40 percent the speed of light?

Yes it is considered more powerful than other methods such as passing antihydrogen particles through a thin uranium membrane

Yes. It leaves a trail of radiating material behind.

No. I've tried it. Didn't work.

You will want a drive that can propel you for a long time, not one that is very powerful. For two reasons. Reason number one is: If you accelerate above 1g for a long time, your crew would probably die. Number two is, after ~2 ly of 9.81m/c^2 constant acceleration, which equals about 2 years on earth, relativistic effects are going to kick in and time's gonna slow down for you wrt to the objects of the universe, which are all moving at non-relativistic speeds. That way you'd be able to reach Alpha Centauri in 3 and the center of the galaxy in 20 years, whereas 5 and 27.000 years will have passed on the reference frame of earth.

Someone over here statet that you get an extreme blueshift from any "light" that comes from your travelling direction. That results in hard roentgen and above rays which stresses man and material beyond any acceptable level. Do you think he'd right?

1. No
2. Accelerating to high enough speeds will kill anything living, so it is not a viable means of travel

It's not just that, if you go fast enough none of your atoms will be able to communicate with eachother as everything would be moving at the same speed and be stationary relative to eachother, thus your bodily functions would cease and you would just die

Yes, that would definitely happen. That's an extreme case of the aberration of starlight. Like when you're running during rain and drops of rain are hitting you in the face. Interesting video on this topic:

Not sure if this would actually happen, since space isn't Lorentz-contracted and time's going on as usual in your own frame of reference of the rocket. But might be caused by the relativity of simultaneity, similarly to Bell's paradox.

This is impossible as "time" as you perceive it is just interaction between matter, how could you experience time when there was no interaction?

why would there be no interaction in your own frame?

Because everything is moving at the same speed, you can't catch up to something that's moving away from you at the same speed.

No. I've never heard about an Orion drive proposal that could get do better than 10% c. A heavily loaded colony ship would have an explorer and would have a hard time working up into the lower single digits.

The time inside of the rocket is slowed down with respect to an observer on earth. But from your POV, time passes as usual inside of it and is slowed down for the observer on earth. So the chemicals in their body will have "enough" time to do their thing.

And how do you suppose that happens when your atoms can't send any signals between eachother?

why wouldn't they since they are stationary to eachother? they are in the same frame

And so is everything else, all the electrons will stop in their orbitals, every electromagnetic impulse will come to a standstill, there will be no information exchange between your constituents, you are essentially dead.

This happens at 1c but it wouldnt cause death itd just freeze you forever

Depends on your POV. From an outsider it'll look like this, but not for you personally. For you, everything would be completely normal. What's the math behind the idea you have in mind?

How do you suppose to decelerate such that all your functions are in sync? Your biochemical functions would break down, the shock would destroy your body.
>>16117538
>What's the math behind the idea you have in mind?
It's called logic, you can't catch something that's moving away from you

Just turn the ship 180 degrees midway through and keep accelerating at 9.81m/s^2.

at 1G in some time. you will eventually stop.

dude at 1c there is no time. a photon's POV ends as soon as it's created. you travel all time/universe in a blip. but you cannot reach lightspeed.

And your brain signals will discharge before the electrons will resume their orbitals, your biochemical functions will not start until electron orbitals and atomic lattices have stabilized which will also not happen at the same time, your body will be ripped apart
>what is moving away from you?
Your atoms from eachother

No, that's billions of years even at c and you're gonna have to go a hell of a lot faster if you want to reach anywhere in a meaningful time

you don't turn the ship around/take a turn. you do a full stop at whatever rate is comfortable for you and then you go the other way. that's the least deltaV, not by fucking "turning"

as a photon it's literally a blip, as a human you cannot fucking reach lightspeed

if you can maintain the acceleration at 1G it would take you around 1 year to "reach" lightspeed. not that much
