    Hmmm, let's see, do I believe the scientists I spoke to while at NASA or someone on this here gun forum and all the research I have done over the decades? That's a tough one...

    This is awesome, but I can't help but be a little concerned when we start bringing stuff back from space, defrosting arctic bugs, etc.

Outside the solar system is another matter per comments in #22, and if tech such as I mentioned above, which is not science fiction (warp drives, etc) but legit tech we can likely develop, who knows.
    You’re about a decade off. Voyager left our Solar system in 2012.

    Hotbig42, sounds like you’re referencing the Milky Way galaxy.

    Some people consider the Oort cloud to be the outer boundry of our solar system so it depends what criteria you are using.

    At its current speed of about a million miles a day, NASA's Voyager 1 spacecraft won't enter the Oort Cloud for about 300 years. And it won't exit the outer edge for maybe 30,000 years.

    https://solarsystem.nasa.gov/solar-s...loud/in-depth/

    Sometimes, it is written that Voyager and Pioneers 10 and 11 have exited the solar system. Though all of these spacecraft have gone beyond all the planets of the solar system, they have not exited the solar system, based on the scientific definition. To leave the solar system, they need to pass beyond the Oort Cloud.

    Voyager 1 was the first-ever object to reach interstellar space on August 25, 2012 when it passed beyond the sun’s realm of plasma influence (the heliosphere) and it is the most distant human-made object. Voyager 2 has not yet reached interstellar space or exited the heliosphere (bubble of solar plasma). Pioneer 10 and 11 are no longer transmitting science data back to Earth.

    I did get to speak with some of them during my visit as press to Kennedy Center people interested in the topic HERE.

    I hope to get press credentials again some time in the near future and return. I say, develop a fusion reaction motor, get the fuel (Helium-3) and launch from the moon which ends the fears of nukes, and other issues. They are already looking at legit mining operations on the moon for Helium-3. We are now in the beginning of a race to get back to the moon and start mining it. China, US, India, all in motion to do it, perhaps we will see mining operations in our life time.

    I had no idea OUR moon was a source for Helium-3. I thought we were looking at going out to Jupiter, Saturn and it's moons one day for Helium-3.

    More like dependent on which def one uses. Personally I think of the inner solar system most are aware of, or the heliosphere if i recall correctly.

    I was just explaining the technical definition that was raised. I personally think it's amazing that V1 and V2 are both still sending back data 45 years later.

    So, serious question as I’m dumb, yet fascinated with this stuff.

    Is “warp/light speed” possible and if yes, how would you do it without hitting “objects” in space?

    They used that for Moon (2009). Pretty good as I recall.
