Nuclear Experiments to travel through Space

<< < (5/7) > >>

kitamesume:
 :D its like how electricity conducts, passing electrons through matter, but what if it could pass everything through matter?

Edit: well anyway, before they start transporting humans through godly distances they should start with chunks of elements, if they remain intact then step up to transporting solutions or compounds.

Freedom Kira:
How is that instantaneous? Do you realize that electrons moving through matter don't move "instantaneously?" They have velocities too.

I swear, you're just around to drive some of us crazy with your weird ideas. You don't seem to understand more than half of the concepts you talk about, and more than half of the rest of the concepts are stuff you invent on the spot.

kitamesume:
by instantaneously i meant transporting the whole thing at once instead of piece by piece or at the least increase the rate of transport(like pumping up the current), though indeed there still is a limit.

thats why what ifs and proposals gets denied :D

That limit is called speed of light...

There exist theories about FTL Speeds, but those include exotic matter and negative masses. And those aren't found yet in reality.
And for teleportation: Even if you use entangled atoms, those still have to travel the distance to the other place you want to reach with lightspeed, so you don't really win something there. And the mentioned "destroy the human - recreate it at the other place" has the whole soul-aspect too it. Is the new human really the same as the old? No one knows yet for real what really makes us us, as in where in our body is our personality etc. Is it just a physical reaction happening in our cells, or is it something more etc... Add the uncertainity principle, and you have a hell of a theorie to create and proof before you can go and teleport people all around the universe.

And then Wormholes: No they aren't those nice 2d-disks we all see in sci-fi series and learned to love (hello Star Trek DS9)
They're 3d-objects (think of a sphere), highly theoretical, and you don't really want to enter them.
First type of Wormhole: The bad one aka Einstein-Rosen Bridges
First of all: Enter the entry-side aka. Black Hole. Nice place, not to crowded, and the gravity... just like earth.
Second of all: Hu... whatever...
Third of all: Leave the White Hole.

Second type of Wormhole: I still live, yeah! aka Morris-Thorne wormhole
Uh, we need exotic matter, okay, let's forget it.

Even if you can create stable 2nd types, you can't think of them like:
Enter near earth, leave near jupiter.
Wormholes don't only jump through space, they also jump through time, so you would have the small problem of not getting to your target in the correct time ;)

The math behind it all is complex, so take a look if you like ;)
All in all it will take a hell of a lot more time until we see FTL travel, since more or less all theories about those speeds need exotic matter and/or negative masses.

For speeds below lightspeed, yeah that's quite possible, although you'll need really high energies at higher speeds because of the increased mass through speed. Add time dilation and the headaches start.
If you forget about current laws regarding nuclear reactors and space (it's forbidden) and about some other stuff, you could most likely get up to 50% to 70% lightspeed (just a guess, not calculated right now, so all numbers are most likely to be lower/higher as in: it takes longer). Still fast, but since the next star is already more than 4 Ly away it would take ~8y to get there, acceleration and deceleration included. You'll have to use low acc and dec since you don't want to kill your travelers.
Oh, and don't forget the fuel to return. And the materials you need to build stuff there. And food. And...

Russia started to work again on nuclear powered propulsion systems this year and i'm curious what we'll see from them. But don't expect to see a ship up there with space for a few hundred people (the longer the travel, the more you need, just from the psychological side) and space for all the needed stuff they need to take with them in the next few years.

You can forget about the return trip. If man were to travel at such distances, he'd use a self-sufficient system (similar to those in Macross F) in the trip. Building such a thing requires a lot of resources; possibly all of man's available resources. It's a one way trip because man will probably have nothing to return for.
