Question

why did the time traveller say that there is no machines?

Answer 1

$\huge\mathcal{Answer:}$

In the gallery with the machines, Weena's fear makes the Time Traveller realize that the floor slopes into darkness. In the dark corners there is much less dust, which is a sign of the presence of Morlocks. The Time Traveller breaks a lever off of a machine to use as a weapon, and imagines bashing in a Morlock's skull.
