Default Travel Among Stars ?

Amusing how fools continue to tout this impossible concept !

Distance = Speed x Time . Do the simple math !

Even at light speed c, times would be prohibitively long, even for relatively short hops between close stars. And practical travel speeds will likely be vastly less than c. Our fastest space probe so far is slower than c by a factor of about 30,000 .

Also, although there are likely many space faring intelligent species throughout the universe, we are clearly never visited by any.

Case closed ( or should be ) !

Just a lot of man-made nonsense. Of course we can travel to the stars!

Man hasn't done it.

No alien has done it up 'till now, including essentially an infinite number, over trillions of years.


You are not aligned with the facts. It has been done many times.




That's essential proof that it can't be done, even neglecting known laws of physics which also say it's impossible.



Our defective primitive physics does not prove anything.

Your unsubstantiated assertions do not prove anything either... and how do you know that our physics is defective?

Because human language itself is defective.
