Why ? Because practical deep space travel is clearly impossible.

Do the simple math :

DistanceÂ* =Â* Speed x Time

Distances are far too great, Speeds are far too slow and
Â* Times would be prohibitively far too long .

Note that our fastest space probe so far is slower than light by a
factor of nearly 27,000 .
So a one way trip to our very nearest neighbor Alpha Centauri at only
4.367 LY
Â* would take 118 Millennia, where i Millenia = 1,000 years.

Even in the extreemly unlikely event that speeds could be increased to
near light speed, times would still be prohibitively long.

To your "prohibitively long".
That is only if you think that anything past your life time
is prohibitively long.

Interstellar Traveler: NASA's Voyager 1 Probe On 40,000-Year Trek to
Distant Star
By Mike Wall September 13, 2013 Spaceflight

Now that NASA's Voyager 1 probe has left the solar system, its next big
spaceflight milestone comes with the flyby of another star — in 40,000
years.

Voyager 1 entered interstellar space in August 2012, nearly 35 years
after blasting off, scientists announced Thursday (Sept. 12). As it
leaves our solar system behind, the robotic spacecraft is streaking
toward an encounter with a star called AC +79 3888, which lies 17.6
light-years from Earth.

A star field image shows Voyager 1 spacecraft's next destination in the
universe (circled). According to NASA, "In about 40,000 years, Voyager 1
will drift within 1.6 light-years (9.3 trillion miles) of AC+79 3888, a
star in the constellation of Camelopardalis which is heading toward the
constellation Ophiuchus." Image released Sept. 12, 2013.

So it will pass 1.6 light-years for a star that is 17.6 light-years away!!

So with-in about 9% of the total distance! Is that really note-worthy??

Alien planet has 16 times greater gravity than Earth.Thus they know coming here is NG. bert
