Since it's 20.5 light years away, it would take a little over 20,000 years to get there in a slow flat mach 1 zero gravity environment. A constantly increasing acceleration to midpoint would give the inhabitants of the spaceship the gravity of earth, gradually increasing to that of Gliese 581c. At midpoint, the inhabitants would experience a short period of weightlessness while the ship turns around before it begins to decelerate in reverse fashion.

To simplify the equasion, I'll allow a constant acceleration and deceleration at Gliese's gravitational rate (1.6 times that of Earth).

do they mean from a certain point on there's no empty space, vacuum, space to expand and just nothing ? how it can be possible ? in any case this universe we are living in doesn't make sense because either we are living in a universe which has no limits or has limits. but what's the limit then ? a big wall ? where it is standing/hovering/whatever and you know... and if has no limits that this is even harder to understand, isn't it ? if there was nothing and simply nothing before big bang but just that little thing which created everything, how come it exploded or expanded in nothingness ? cause nothing means no empty space. nothing means nothing, it wont let anything to move, explode or expand in itself (there's no in or itself actually "there") in fact it (nothingness) can't let big bang to exist even.

what you think ?

Let's say I get in a spacecraft and travel close to the speed of light. By the theory of relativity, I may come back having aged only one year while the Earth aged 100 years.

The part that confuses me is: Why can't the opposite be true, i.e. I age 100 years while the Earth ages 1 year? By my frame of reference, I am standing still while the Earth is moving close to the speed of light. Whose frame of reference determines how fast time is moving?

In my little knowledge, the space matter always moves but, if it
moves quickly or slowly, oldens fastly or not depending upon the theory of the relativity, so, it depends only on physicist to
define the time of the universe, but , why do astronomers keep on saying that the the existence began 13000 earthly years ago?
