Where does space end?
No, they don’t believe there’s an end to space.
However, we can only see a certain volume of all that’s out there.
Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists..
What happens when you reach the end of space?
Once we reached the ‘end’, we would only see blackness, a void, with nothing there. The universe is ever expanding, so we would never see anything ahead of us, rushing ‘outwards’, but if we were to look back, to where we came from, we would see stars and galaxies approaching us.
How long does it take to get to the end of the universe?
Finally, our universe would end in an explosion, a singularity of literally infinite energy. Current theories predict that if this so-called Big Rip is in our future, it will take another 22 billion years to arrive.
How long does it take to get to another galaxy?
Travel Time To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager’s speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!
Can we ever travel to another galaxy?
According to our current understanding of physics, an object within space-time cannot exceed the speed of light, which means an attempt to travel to any other galaxy would be a journey of millions of earth years via conventional flight.
Is there an end to our universe?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
