They may be waiting for some time yet then...

Maybe if they set off now, we might be towards the end of the last of the departure extensions in 111 light years time.

I've just worked out how long it would take the fastest object ever made by humans to get to this new planet...

Planet is 111 light years away.

Light = 186,282 miles/sec

186,282 miles/sec * 60 seconds = 11,175,720 miles/min

11,175,720 miles/min * 60 mins = 670,543,200 miles/hour

670,543,200 miles/hour * 24 hours = 16,093,036,800 miles/day

16,093,036,800 miles/day * 365.25 days = 5,877,981,691,200 miles/year

5,877,981,691,200 miles/year * 111 years = 652,455,967,723,200 miles



Voyager 1 probe = 11 miles/sec

11 miles/sec * 60 seconds = 660 miles/min

6,600 miles/min * 60 mins = 39,600 miles/hour

39,600 miles/hour * 24 hours = 950,400 miles/day

950,400 miles/day * 365.25 days = 347,133,600 miles/year

652,455,967,723,200 miles / 347,133,600 miles/year = 1,879,553 years



So nearly 2 millions years for the fastest object ever created by humans to reach this new planet.

I won't hold my breath...

You are of course completely wrong. I think you will find the fastest object ever known is a hire car :)

Who knows, maybe the life forms on that planet are at this moment looking at ours and thinking ‘Mm, that planet has water and might be the saviour for our species...’
The image we see of their planet is 111 years old. Maybe they were observing an image of our planet thousands of years ago, having already abandoned their K2-18b after ruining it by experimentally pursuing feral concepts of evolution in an age of economic development.

Ironically 111 years ago is roughly when Earth started broadcasting publicly. Has K2-18b already received morse code and opera?

111 years ago. Isn't that about the time that electric cars and petrol cars, and maybe others, were in competition equally before petrol cars won. Maybe that's what they are watching right now, wondering how that will play out.

The nearest planet is over 4 light years away. If we are capable of thinking logarithmically, in terms of orders of magnitude, 4 light years and 111 light years are reasonably similar in distance. The nearest planet, in that sense, is similar to this one in distance. On cosmic scales, there are suns and planets much, much further away than 111 light years. If the universe was scaled to the Earth, 111 light years is probably like your next door neighour or your local village shop or something like that.

Traveling 111 light years, or 4 light years, is far, far beyond current technology but who knows what technological leaps forward, or changes to the understanding of the laws of physics, might happen in 100 or 1000 years.

@Electric Jamie, in other words, you are saying there is a credible alien threat to our planet?!

Maybe we should send them an asteroid with our hardiest microbes aboard? Maybe they already sent us an asteroid with the same?

Maybe we'll manage FTL travel one day. There are a lot of things we used to think were impossible, until they were. At which point I think we'll have plenty of new planets to choose from.

We need to put more resources into science and space exploration though instead of distracting ourselves with infighting all the time.
