Believe Me, We Will Never Travel Among The Stars!

The distance separating us from Proxima Centauri, the closest star to Earth, is 266,000 times greater than the distance separating us from the Sun, and 103 million times greater than the distance we had to travel to conquer the Moon. IN this video we will talk about stars colonization.
Impressive, isn't it? Could we colonize stars?
Space colonization has always been a fascinating dream to realize.
Even a ray of light, moving at the maximum speed allowed by the laws of physics, takes 4.3 years to reach us from Proxima, while less than 8 and a half minutes are enough to fill the space that separates us from the Sun.
In these numbers, in their relentless inevitability, is enclosed the problem of interstellar travel.
If we take into account the size of our Galaxy (about 100.000 light-years diameter) and the size of the observable Universe (more than 12 billion light-years), considering the question of the trips in the cosmos can only leave us a deep sense of inadequacy.

I have a feeling there’s physics in the universe that humans haven’t even began to discover.

A 10% C speed would allow a trip to Alpha Centauri in just 43 years. Question is, how well do we understand the density of interstellar debris?

[booshter]

"We will never travel among the stars based on current scientific understanding and technology" would be a more honest title.

There‘s a small mistake when the number for the speed of light is mentioned the first time. It is not 299 million km per second but 299 thousand km per second (or 299 million meters!) Very good video!

the frustrating thing about lightning speed is that it is still frustratingly slow compared to the size of our galaxy or others, if we attained the possibility to travel at lightning speed we would still be like a snail trying to travel around the earth's circumference

Just because we currently don't know how to visit other stars, doesn't mean there isn't a way to do it. It simply means that WE DON'T KNOW of a way to do it. Humans are constantly learning, and given a little time we will figure out a way.

As a kid i always imagined space empires and other crazy stuff.

As i grew up i realized that it is a waste of energy to try it. So much time to get to one place, communication would be a nightmare. All the alien invadong Earth movies look now ridiculous to me.

Why waste so many resources for a war? By the time your planet knows the result of the invasion, your leaders may be dead and theres probably a new party in power or there was a war and people no longer care about you.

It is easier to fix all the problems in your planet than to try and invade others, at most i believe we could land of asterpirds or meteors and extract materials from there.

Its not just about getting up to speed and the risk of possibly hitting something its also about trying to stop once you get there. You cant just stop in space going that fast.

[randoir]

FINALLY, someone had the balls to say it and back it up with science If we as humans continue to in fight over ideologies and political leanings. we sure as hell aren't exploring space anytime soon.

The dilemma that has always confounded me when I think about space travel is one of simple
Geography. The information we have (ie, what we see) is old information. The light from astronomical sources we see is old (as much as thousands or millions of years in some instances). Those objects have moved in that time (the galaxy is rotating and space itself is expanding). Flying to Vega, for example, is not like flying to Vegas. Because Vegas is always in the same location. The best we know about Vega is where it was located 25 years ago. Although Vega is “close” and unlikely to have moved much “galactally” in 25 years, the problem is much worse for more distant stars, let alone locations outside our own galaxy. Also, we all know stars go through phases, one of which includes a supernova. Given we are always acting on old info, it is entirely possible we could chart a course to “Star Z” only to find Star Z has exploded in the hundred or thousands of years it took its light to reach us when we charted the voyage. Creating reliable and “dynamic” maps that adjust for historical movement of objects and future movement (during the time it takes to make the journey) strikes me as a daunting proposition in and of itself.

My grandma just passed at 95. She told me jets used to be in books and people would scoff at the absurdity of travelling at the speed of sound. It we make it, say 1, 000 more years who knows.

[Bropann]

I am aware of how often in history someone has said that a given event, situation, etc. was impossible. Further, I will admit that it appears, by what you have said, that interstellar travel at a reasonable rate is impossible. That being said I firmly believe that time will prove you wrong and that we or someone else will indeed travel between the stars.

[KingOpenReview]

This just means you can't make the well connected galactic empires you see in a lot of sci fi. It doesn't mean groups of us can't just move through the universe slowly.

[openmac]

"Believe Me, We Will Never Travel Among The Stars!" wow. I'll bet you're a real hit at birthday parties & weddings

[coalcrackercletus]

There was a lot of people who said we'd never be able to fly either, we've made it so far in the last 120 years, it's insane to think we'll never leave our rock lol

[stevenschilizzi]

As they say, “never say never” because you never know!
Given what we’ve learned in the last hundred years or two, and that things are accelerating, imagine (if we manage not to blow up the planet to oblivion) what currently unimaginable things we might have discovered in the next hundred years or two. This video is perfectly sensible, but it should add “in the current state of our knowledge”. Who, in 1850, could have imagined the Internet or the GPS? Not even Jules Verne did.
Also, who says we need to explore the galaxies with our very inadequte biological bodies? Maybe that will happen only once we’ve transformed ourselves into some kind of electromagnetic entity or uploaded ourselves into one? There are probably more surprises lying in wait for us than we have ever experienced in our past history. Hopefully not total self-obliteration though…

In a way, it's comforting to know that we'll be safe from malicious aliens who might show up at our doorstep one day. On the other hand, knowing that there most certainly is other intelligent life out there but we'll never meet due to the vast distances involved, is quite sad.
