RE: Why Haven't We Ran Into Alien Lifeforms Yet?

trump stuff is just a joke :)

1. Intergalactic travel is very difficult, but with rocket propulsion, a civilization slightly more advanced than we are can colonize every habitable planet in the entire galaxy within a few million years. Given that they've had 14 billion years (slightly less, the first few years were not fit for life), it's still highly probable for our entire galaxy to be colonized long before the earth existed with a modest estimation of technology.

2. Not too sure what you mean, but if you're saying we're likely in a computer simulation, then that may be true, but why simulate this vast universe but not bother adding extraterrestrial life for consistency when you can just simulate a much smaller but self consistent universe for us to reside in?

Thanks for reading

nope
our rockets are 95% fuel...5% payload (or less)..and THAT is just to get into orbit.
how do you propose to fuel a 50,000 year trip...and that's JUST to the closest star...4 light years away.?

yes but most of the energy is required to leave earth, I'm unsure of how much energy is required to navigate the gravitational fields of other planets on our way out of the solar system, but it might be suprisingly low

I think we're only about 200 years away from leaving the solar system. By which time the trip may be a few orders of magnitudes faster and depending on anti aging technology, we, or our descendants can begin colonizing other solar systems.

Even if i'm way off with the estimate of tehcnological advancement (I dont' think I am) I think a lot can and should have happened already in 14 billion years and it is honestly a small wonder that we're so isolated outside of our planet.

sorry...you're wrong.
Voyager II launched by NASA on August 20, 1977
it is now

• At a distance of 114 AU (1.71×1010 km) from the Sun as of April 5th, 2017,[6] Voyager 2 is one of the most distant human-made objects, along with Voyager 1, New Horizons, Pioneer 10 and Pioneer 11. The probe was moving at a velocity of 15.4 km/s (55,000 km/h) relative to the Sun as of December 2014

do the math...2017 - 1977?
fastest moving object ever made by the human race?
it hasn't even got out of the solar system yet?
