No. The distance and investment completely preclude this possibility.
@SW-User You can't know that. Methods of travel and equipment could be and probably are 'alien' to us. They might step between universes as easily as we board an elevator.

@Mamapolo2016 Physical laws cannot be overridden by fantasy technologies.
@SW-User Yes, they can. They can't be over-ridden by OUR technologies.
SW-User
@Mamapolo2016 Our technology works within physical laws. Fantasy technology would involve breaking physical laws. We might eventually approach the speed of light but even at this speed it would take millennia to reach some habitable world.
@SW-User So sure. People were darned sure about the earth being flat, too. Because we are too limited to imagine it does not mean it cannot exist. We've been just as sure about things before. A lot.

We are limited by our ability to imagine and by our physical form. Other life forms might not have those restrictions. You may be right, but you might be wr-wr-wrong.

@Mamapolo2016 Scientists are in agreement that all of the physical laws are now discovered. We must work within them and not imagine magical solutions based on past progress.

Space and time build insurmountable barriers.
@SW-User I'd love to stay and talk, but I have to get back to my home planet. You stay earth-bound. That's fine by us. Ta-ta.
@SW-User Just a little food for thought:

Before Einstein, scientists believed that all physical laws to be discovered were already discovered. Of course, that was proven wrong.

If we somehow manage to come up with the Theory Of Everything that even explains dark matter and dark energy, can we know if the TOE is all there is?

If we cannot know that there is nothing beyond the TOE, it might be presumptuous to call it TOE, like scientists did before Einstein. But since scientific method is inductive, I think it is impossible to know for certainty. (And hence the name, theory.)

Presumptuous. Yes, that's the word.
