The Earthling says:

"The Great Attractor is a mysterious place where the Milky Way, Andromeda, and all the nearby galaxies are attracted. It can't be seen because it lies in a direction of the sky known as 'Zone of Avoidance' where there is so much gas and dust. Also, it is tens of thousands of times more massive than our galaxy."

"You'll have a great time there. You'll be able to relax. I have been monitoring your progress."

"I'm doing this because I enjoy it." 

"I do not think you realise the gravity of your situation."

"On the contrary. Gravity is foremost on my mind. Look, I'm trying to make an ascent here." 

Concentration is vital. 

"I appreciate your concern but if you don't stop distracting me, I'm liable to be one with the visitor"
