Are we alone in the universe?
Now that, is definitely one of life's biggest questions.
So far, life in the universe appears to be unique to our planet.
But that doesn't mean that there isn't intelligent life out there somewhere in the cosmos.
Humans have dreamt about it, talked about it, written about it and watched films about
it.
But Have you ever actually wondered what would happen when aliens arrive?
That's the question we are asking today on life's biggest questions.
Hello and welcome back to life's biggest questions, the channel that asks the fundamental questions

Stephen Hawking once warned of the dangers of trying to make contact with alien life
because he said it could mean the total annihilation of life on earth.
Stephen hawking was a very brilliant man, rest his soul, but is he right?
If contact was made with aliens, and they decided to visit us, would that really be
a bad thing?
Well i suppose it depends on what these alien beings want from us.
Of course if they want to harvest our resources, and are willing to take them by force, we
would almost certainly succumb.
If an alien race was advanced enough to make it here across the cosmos, they are most definitely
possess the technology to annihilate life on earth.
But maybe, just maybe, aliens are just as curious about us as we are about them.
When aliens arrive, it will be the single most groundbreaking moment in the history
of human kind.
Contact with aliens will send the world into a complete meltdown.
It will be met with a mixture of feelings, from fear, to wonder, to excitement.
When aliens arrive, it will cement the fact that we are not alone.
According to psychology professor, Michael vernum, at arizona state university.
We would probably welcome the idea of aliens with open arms.
In case you're wondering, if aliens actually made contact with us, we would most certainly
know about it.
The international Academy of Astronautics has a set of protocols in place for the people
who are involved in the serach for extraterrestrial life.
The protocols dictate that if anyoen finds a signal, that person has to make the world
aware, but they also shouldn't respond to this signal.
The awkward thing is, these protocols are simply guidelines, they arent actual rules.
Nothing bad could happen if someone did so happen to respond to a signal from an alien
race, so theres nothing really to stop someone from doing it other than their own fear.
Furthermore, if the entire world was notified that someone had, in fact, made contact with
aliens, someone, if not many people, would most definitely make it their mission to respond
to their signal.
I mean this is aliens we are talking about.
This aint an ex dropping a 'U up' text at 2 in the morning.
When an alien calls, you answer.
Then theres the question of how long it would take for aliens to actually get to earth.
At first, humans would be sent into a frenzy.
Everyone setting up homemmade radio towers in an effort to send a message to these extra
terrestrial beings.
But lets not forget that it takes years, if not decades, for messages to travel across
the cosmos.
At least, thats how long it takes with the technology we currently have.
I'll give you an example.
The closest potentially habitable planet outside our solar system is proxima b.
Its 4.2 lightyears away.
But even at that short distance, it would take 4.2 years to recieve a message from proxima
b and the same amount of time to recieve one back.
That is a heck of a long time to wait for a message.
Thats ghosting territory.
Once aliens recieve our message, it would take years, decades for them to reach earth.
Of course i should consider the fact that aliens probably have advanced technology that
will allow them to travel across the universe much faster than we are currently capable
of.
But even so, these aliens still have to find earth and reach us, which would take a long
time.
Then, the day finally arrives.
Aliens are here.
By the time aliens get here, the contact someone made with aliens was decades before.
most will have grown old, but we will also likely be far more equipped to deal with such
a process.
Presidents will have come and gone, younger generations will have grown up with the idea
that extra terrestrials may one day come to our neck of the cosmos.
THere are currently no protocols that we know of for what will happen when aliens get here,
that will most certainly change if we become certain that aliens do in fact exist.
world governments would have spent billions on defense and technology to prepare for their
arrival.
But still, even if aliens get here, with their fancy ships we would welcome them.
It might be a bit difficult to communicate with them at first, but as I said, scientists
would have had years to prepare for their arrival.
Some method of effective communication will have been set up, and with it, we will converse
with these aliens, maybe through pictures or gestures.
Its diffuclt to say if these aliens will just be visitors, or if they will stay here.
I mean, whats not to like about our big beautiful blue planet?
My guess is they will probably stay and live among us.
Maybe they would help us with the advancement of our technology.
They could teach us how to fix our damaged environment.
Teach us how to harness the power of our sun that will enable us to advance our space travel.
They could teach us things like telepathy, teleportation, how to harness the power of
black holes.
But then, some people might not be so welcoming toward these aliens.
Humans are often unwelcoming even when it comes to members of our own race, imagine
how some people would behave if advanced extra terrestrials arrived.
Maybe some humans will take it upon themselves to alienate these aliens and try to send them
packing.
There are some scientists that will probably kidnap aliens and essentialy make them lab
rats, testing on them and researching them to figure out how they became so advanced.
And use them for our own personal gain.
Thats of course a grim way of looking at it, but then its very difficult to imagine what
would happen if aliens arrived, it hasnt happened...yet.
But now i open up the question to you dear subsrcibers, what do you think will happen
when aliens arrive?
how will humans react? will it be with open arms, or will we be hostile?
let me know down there in the comments.
For now, i'm going to wrap up this video by featuring some of your comments,
That guy there - what if jack finch was real. as i work with jack and see him on a daily
basis, i can confirm that jack is, in fact, real.
Hugo Vasques - what if this channel gets creative and doesnt just describe from a wiki. then
someone will say that we should stay objective and not get creative.
By the way, i can confirm that i did not use wikipedia for this video.
Other than one article, i used my imagination.
Squillium fancyson - do a what if youtube stopped paying its creators ad revenue.
well you would probably not have very many creators to watch.
I sure as hell wouldnt do this for free.
