interstellar travel

i think it is possible somehow. does anyone have any thoughts on interstellar travel and how it could be achieved?

 

i think it could be possible. there could be places with inteligent life, and came up with a way with intersteller trave.

 

Wouldn't that require the bending of time and space to achive that type of travel.

 

not sure

hmmmmmmm not sure. maybe. it would make it harder though, obivously.

 

I think antimatter is the route. That is if the gamma rays, explosive properties, and G-forces don't kill us in the process...

But the praticality of it increases with speed. The faster you go, the slower time goes for you. But even at speeds of 99% percent the spped of light you can talk 50+ years to get to a nearby star, not to mention back. If we want to leave the galaxy, you begin to start talking generations not just years.

 

good point

i know. still at some point itll be vital. i think eventually we'll be up to it. sense of survival will force it on us.

 

I personally think it to be too much of a giant leap even for theoretical divisions. I think intrastellar should be and will be the primary focus for the next 500 years. No sense in trying to walk when we've just learned how to crawl. Heck the best idea we have right now is strapping a crew of 5-8 people to a really big bomb in hopes that it takes direction.

 

another good point

we should learn to fix our own planet so when we can live on it mildly more comfortably then we can leave.

 

Lol, humans can't "fix" everything. In the society that we live in today most people grow up thinking that nothing is out of our reach. This is, of course, a lie.

 

yet more good points

yeah youre right in that. hmmmmm. and im not exactly mr. happy huggy human race either. yet we should fix the problems that can be fixed all the while gazing toward the sky.

 

Well it obviously is not possible now but some day it will be. And well maybe if the government spent Trillions maybe even quadrillions of dollars then maybe they could but that is a long shot. Right now it would be too expensive and too unnecessary.

 

It can't happen. As things reach the speed of light, time slows down for them, then become a singularity in essence. they will achieve and infinite mass. We would basicly be crushed under ourselves.

 

lol that is true. The only possible way that they could is if they goo just below light speed. Even that would be dangerous. But then again when has shooting a bunch of people into an endless darkness been a safe thing?

 

Both very good points.

I personally think that we should look more towards our own planet before we go off in search of others. For example, did you know that we know more about space than we do about even our own oceans? There are so many things that we do not yet have an understanding of, that to leave in order to travel and find new places (which I assume would be the point of the travelling) would just leave us with even more that we don't understand.

How could we hope to understand the universe when we don't evn really know our own planet?

I don't think it will be possible for many, many generations, and at the present time, I really don't thinkthe human race is ready for it anyway. It is just a dream xD created through our constant desire to know everything.​

 

Interstellar travel is possible just not in the way Star Trek may have made you believe. It would require massive amounts of energy from massive engines which would increase the mass which would make more energy required etc etc.

Also the time factor. Humans only live so long. A concept was developed where families were put in a self-sustaining ship. This ship maintains its own environment with air, food, water, heat etc all maintained at habitable levels. Then the families and crew would live on the ship over its journey. Many would die from natural causes as they reach the end of their life span. But the point is the families have children, who have children etc. So the descendants of the original crew reach the destination, hence why the ship would be known as a "Generation Ship".

Other methods such as using 'wormholes' would allow us to bypass space and travel almost instantaneously, but we are centuries away from that technology, if we ever reach it.

 

One theory I've got that we are not going to reach anytime in the remotely near future is this. Use antimatter to obliterate our bodies and make it pure energy, then send that energy to another location at the speed of light, and then convert the person back at the other end based on the energy signal.

Major problems here being, 1) Is there even this energy signal? 2) Can a machine read it and reconstruct the person safely? 3) Energy deflections.

Obviously not a perfect system, but it would still be really cool if it actually worked out.

 

^Many problems with that.

First of all, all electromagnetic waves travel at the speed of light (roughly 3x10^8 m/s). Meaning there would still be a speed limit. Also, you would have to send the machinery in the first place to be at the other end. Then you would have to wait for communication confirmation that it arrived and is fully functional. Then you would have to run tests. Then you may or may not send someone. You would have to wait for them to arrive and to communicate to show if it was successful or not.

Veeerrrryyyyy complicated =/

Oh and I just remembered, would the energy produced not be mostly uniform? When matter is converted to energy, the only difference between two different conversions is the amount produced.

 

It doesn't matter either way, cause if we were to travel at the speed of light, we would come back to the earth either 50-1000s of years in the future. Time is different in the two realms actually. Cause by the time we were to return a large span of time would have passed, which would just suck hard.

 

I'm pretty sure some scientists said it wasn't possible. But I may have heard wrong *shrugs* I'm pretty sure there isn't anywhere I'd like to go to anyway.

 

Science should never claim that something is impossable. It may be unworkable now, but very few things are truely impossable.

But it is true that time dialation only would effect you. if you reach the speed of light then it would be instantanious for you but everone else will continue with you gone.
