The destruction of humanity by itself is inevitable. We can't even evolve pass primitive matters like religion, sexism, racism, general discrimination, population problems, political issues, etc. To think that such a primitive species could ever achieve interstellar, let alone intergalactic, capabilities is delusional.
do you think humans will ever be capable of interstellar or intergalactic travel?

They aren't?
Really?
I'm curious how one could claim to have both a rational mindset and claim what you have.
-----------------------------------------------------------------------------------------------------------------------
As to the original question:
We already have the technology and the ability to travel to other star systems.
The unfortunate reality is that it would be the great great grandchildren of the crews that launched who would actually arrive in the target star system - and it's quite possible that they would find out that this other hyper-advanced humanoid species beat them to it... because they are our own descendants who made a breakthrough in near-light or FTL travel a hundred and fifty years after the first crew left.
But that does introduce some interesting moral quandaries.
People tend to get upset about abortion being an involuntary end to a life given no chance at a future. What is to be said of the generations aboard a generational ship whose purpose is decided at birth? They are to live, produce a couple offspring, raise them to continue the mission, and die.
I think any practical generational ship idea would have to include a means for cryogenic preservation and revival. Basically - the successive generations would be able to be frozen and revived when they reach the destination - so all generations would effectively be able to reach the destination while maintenance on the ship could be continued (of course, this begs the question of why not just freeze everyone to begin with, if we have the ability to do it and return people to life?).
Anyway -
I also believe that it is possible for a form of Faster Than Light travel to exist. I do not believe, however, that it will involve wormholes, 'warp bubbles' or other contrived nonsense. I think it will be as simple as "It was in this place, now it is in that place." The world of QM is much more tolerant of such behavior from objects than contrived warp bubbles and fields that have no precedent.
Of course... if we knew how something like this might be done - then we'd have some solid experimental data to hammer out a theory of how to do this on a larger scale. Right now, the speed of light seems fairly impenetrable.
Even so, propulsion technology is improving quite quickly. VASIMR drives are looking to be the drive system of choice. Scaling the drive system up for higher thrust ratings is possible, and I posit that the magnetic field can be strengthened to the point that fusion can be induced as a sort of 'afterburn' for even greater thrust (but reduced efficiency) values.
There are some other interesting developments in plasma-related propulsion (such as the double-layer drive) - all of which have their potential applications.
I think we will get much farther than we believe possible, currently.
But I don't know how quickly we will get there.
Consider history for a bit.
Imagine you were living in Europe during the 1200s. You're surrounded by the echoes of an empire that you know was great - that historians talk about and culture still reveres.... but you look at its relics and you can't even begin to maintain them, much less recreate them.
Yet, here we are, today with the ability to do things the Romans could only dream of.
Sure - they did some clever things that we will probably never know, for sure, how they pulled them off... as with the Egyptians before them. Every great culture has left its share of accomplishments and mysteries... but we've moved forward.
Even during the dark ages, we were refining the process of forging and tempering steel. Chemistry was coming to light. Concepts of health were becoming more common as plagues wrought destruction.
Perhaps our own civilization will decline for a time. When a forest becomes too cluttered with the old, dead things - a fire will surely cleanse the ground to make way for the new.
Imagine that our grandchildren grow up without being able to mass-produce cars, but still have computers and automated production concepts like CNC machines and 3d printing. The world they'll create will be completely different from ours with different solutions to some of the problems that we solved a century ago and haven't revisited.
Perhaps they will only rarely recreate our massive factories, preferring to have a "replicator" in every basement - even if their power is only on for 6 hours of the day.
It's hard to say what direction everything would go.
But, eventually, we would look to expand to the stars, and we would begin solving that problem once again, no matter how hard of a blow we are dealt.
They are?
What I thought is that if there were other intelligent life forms in our galaxy then they are likely advanced than us and we are searching deep in space for a sign of aliens.Space is too vast may be that is the thing that makes interstellar travel impractical even for an advanced civilization.
never claimed I have rational mindset I would always like if some enlighten me how logically flawed and stupid my statement is.

The people in the 1700s believed that if planes existed, people would die because of the air pressure and it would be unable to fly, and even if it managed to reach the sky, we would asphyxiate, and just look at how well they work; none of their claims were right.
You boys need to be more open-minded - of course we will be capable of interstellar travel, but of course, that's if we don't die tomorrow because of the nukes and maybe even more advanced explosive weapons that could destroy the earth.

I believe the erroneous assumption is that our attempts to search space are actually looking for valid indications - or that we actually know what advanced society would look like in terms of emissions.
Consider the indirect ways we used to track humans or find signs of their passing.
"Well, there are no camp fires here."
"We see no signs of beasts of burden. No droppings."
"No smoke signals or burning beacons, either."
We could be looking for all the wrong things.
Or, even more troublesome is this idea - suppose a civilization exists on an island in the Pacific along the major traffic patterns of the Asian airports. They have never had any contact with humans outside of their island.
Do they consider the airplanes they see on an hourly basis to be indications of human life, elsewhere?
Or are they some strange type of bird - a flying object that is natural and far more familiar?
Perhaps one of them cites an old legend about bearded men who came aboard a whale of steel that breathed smoke over a hundred years ago and suggests the strange birds in the sky could be something similar.
But if they were humans ... why wouldn't they come down and introduce themselves to the islanders? Surely, life is important and rare. It would be great for those humans to know they are not alone in the world.
A few of them try to light smoke signals or shine mirrors up at the airplanes, searching for some kind of smoke signal or flashing light in response to no avail.
Others insist the aircraft are part of some kind of natural phenomena - they always have been and always will be and that's all there is to it. No crazy sky people or anything like that.
Basically - what I'm saying is that we lack the perspective to even realize when the phenomena we regard as being natural are, in fact, the product of sentience. We could be looking at intergalactic travel hubs and simply not realize the significance because we are only looking at the electromagnetic spectrum. Perhaps there is more to our universe than the electromagnetic spectrum - and if we were to look through that - we'd find the universe filled with data being sent back and forth.
From a logical standpoint - there's absolutely no reason for an interstellar society to use electromagnetism for communication. Its utility outside of local environments is severely hampered by the speed of light.
They would either not bother to communicate over such vast distances because they have not discovered FTL - or they would have already harnessed the FTL phenomena for data transmission - and the means of harnessing it may not be related to the electromagnetic spectrum in the slightest.
In which case, we're barking up the wrong tree.
That doesn't mean we should stop our best guess efforts - but I'm just saying that using RF for interstellar distances is just unlikely. Even the hum of our 60 and 50hz power generators fizzles out once you get outside of our solar system. The noise from our sun's heliosphere renders all of our industrial success to nothing worth taking a second look at for an alien SETI.
Even the lag from Mars to Earth is substantial enough (even at our closest orbit) to make RF communication very nuanced. Internet protocols would have to work in bursts, few sites could truly offer browsing the web of a site not hosted on the planet... It's just a mess.
And that's just within 'our block' of the solar system.
They would be using something else. Even if they were to use RF as the medium for the data - they would be using something else to transport the RF signal at FTL.
Why wouldn't we? The way I see it, it's human destiny to reach out to the stars. We have already made such a leap in technology and we have so much more to see. Just this year in fact, we successfully transmitted information instantly, and I mean instantly, read up on Quantum Entanglement. We still have so much more to learn and we will succeed.

Human body is a prison, we can't even travel at speed of light, we can't support such speed and would probably collide something at this speed, antigravitation, teleportation or wormhole won't change anything. I've heard about interstellaire travel with astral travelling .
I think that it is physically impossible we'll have to travel at a faster speed than the speed of light, mutch faster because there are thousands of years of light traveling between two stars, millions between galaxies.
Something that defys the laws of space and time
The stars we see at night are the stars as they wer millions of years before, some of theme doesn't even exist at this moment but the light waves created by these stars just came to earth from millions of years of travel reflecting the image of the dead stars.
