Interstellar travel??No one can answer that definitively because it’s not possible now and it’s not likely in the future, but not impossible.
No one at present can cross Interstellar space, but we have sent probes out there, like Voyager I and II and New Horizons. It will take Voyager I 40,000 years to approach a star only 17.6 light years away, so the distances are just fantastical.
Although in the future it might be possible to build an interstellar vehicle for people to live on, an interstellar journey would take hundreds or thousands of years. Many generations of people would have to live and die on that spacecraft, and the descendants of those that launched the thing might come to resent the decision of their ancestors.
We will never be able to travel faster than light, and that speed limits us. We can’t even get up to 10% the speed of light without using more fuel than the weight of the Moon, and that’s just to get up to speed. You have to use the same amount of fuel to slow down once you reach your destination. The best we will come up with is something like what is in the gallery above .
