"Just because a planet is the same size as Earth, doesn't mean it's like the Earth..."

Well, duh!

"55 Cancri e" is not a super-Earth it's a super-Venus ;)

So, can I use my earned flight hours credits to go there ?

Hope they serve flight dinners in route....

it would also be a tidally locked world that may have a ice cap on one side and scorching death on the other and somewhere in between there is a MY little pony like world with rainbows flying purple ponies and predators that mutilate them from time to time.

In Sweden you could wear a t-shirt in December last year. The year before that it was minus 10-20 degrees Celsius.

I watched that whole thing to learn that? They should have started the video with that so I could have known not to bother watching.

200 Billion stars in the Milky way galaxy * 1 Billion Galaxies = 2 × 10 to the power of 20

If we are alone then we are wasting our time here on earth and we should already be colonizing and terraforming other planets to spread our species because if something catastrophic happened here on Earth we would be destroying the only planet with life in the universe.

Think about it.
