By what year do you think that people from this planet will be able to travel space?

i guess there will be no date when man will be getting such a huge achievement of connecting itself to other other galaxies. It will remain a dream and a hope for many many scientists over the years to come. To actually see, to travel in outer space we need a lot of resources like petroleum and other metals, and by that time all these things will get depleted and we will never have the scope of reaching outer space.
