4.5 Billion "Alien Earth" just around Red Dwarf stars in the Milky Way

[Danno]

Just estimates, but the discoveries coming from Kepler are getting more and more amazing

Sign me up ill take a ship and crew there to check it out.....

How fast can we currently travel a light year?

Well either way Im game even if it takes the rest of my life and the next generation to get there.

Or we can do a ship like in the movie Pandorum.


Edit: anyone Think its still impossible for other life to be out there?

Voyager 1 is has been opperating for 35 years and it just now left the solar system.

Okay so thats running on 35 year old Technology. How fast can we get there now.

(and if i manage to die in space ill be happy even if i just make it past saturn lol

That's very exciting. The human race is in for a very exciting time in the next couple of centuries!

Thanks for sharing, Danno.

Not much faster at the moment. We could build large solar wind sails which over time might get us to 1/10th the speed of light.

Same with using nuclear concussion propulsion. About 1/10th.

Now I'm not sure how much time dilation there would be at 1/10th the speed of light so there could be a discrepancy on how long it would take when comparing those in the ship to those back on earth.

From my understand the closer to the speed of light one travels slows down the passing of time for them. (but not for the people still back on Earth)

I guess first step is to build ships designed just to travel space and not to launch from earth first so we can develope a better and possibly renewing fuel source to use.

The reality is we need to be able to manipulate areas of physics that we are just not advanced enough at the moment to do. Primarily, mass and gravity.

Scientists understand that it is useless to send out a ship to a nearby star that will take it 200-300 years to reach, when in that time we may develop technology that will allow us to reach that destination in days/months or even just a few years. How would you feel being the 5th generation ship bound person that makes it to the destination 50 years after humans had already made it.

Not to mention the serious issue with space travel and the human body. Low gravity issues with bones muscles heart…Radiation…the list is enormous, and is primarily why we haven’t sent humans to even Mars as of yet.

I know.. Once these private sector companies decide to go fot it on the mining astroids our space travel abilities will improve Sadly its gonna take the motivation of Profits to get humans patrolling space.

Can't the new ship pick up the old ship as it is passing by?

A little radiation never hurt nobody.

Yeah...that wouldn't suc either. It's also an incredible waste of resources.

Oh, come on, what's the challenge in that? Try to make it past Uranus.

Well, 200 seconds on the spaceship would mean 201 seconds on earth (if I used Lorentz correctly). - So every 200 years you would have saved one year. Doesn't seem like too much.

The Mass Effect. It's from a video game, but the theory is actually relevant to real life. It uses dark matter to manipulate gravity, and thus mass, to move at the speed of light and other things involved with gravity. The game actually uses real science, it just so happens it doesn't exist yet lol

the slip gates in that game could be out there.... who knows...

I don't see how anyone wouldn't think that there is other life out there...

A company founded by former NASA astronaut Franklin Chang-Diaz has been developing a new rocket engine that draws upon electric power and magnetic fields to channel superheated plasma out the back. That stream of plasma generates steady, efficient thrust that uses low amounts of propellant and builds up speed over time.

It will be able to reach Mars in about 40 days, as opposed to 10 months. But even this does not help us leave the solar system soon.

I really hope we land on Mars in my lifetime. Then I hope we start mining helium-3. So much to do and see....

[Stewy]

Interestingly, if you have ever read Carl Sagan's Cosmos, there is a chapter in there on reaching out to the stars. In it he goes over the 4 mostl ikely space flight scenarios (keep in mind this is pre-1980), the theory behind each, how fast each would theoretically go and how plausible each would be to build and execute today (then 1980). The two most immediately viable were also the slowest, but impossible to even consider because they both relied upon some form of nuclear fuel, and the use of nucelar materials in space was banned at the time. The two fastest were very highly theoretical, and not really feasible without advances in technology.

The slowest one which was doable with 1980 technology could travel at 1/10th the speed of light, which while not fast enough to cause Time Dialation, would be significantly faster than any current technology, but as i said it isn't feasible due to nuclear bans in space.

More details are in his book but he discusses this in hisd Cosmos series - http://www.youtube.com/watch?v=p4HGaTovMMc - start at 28:00 but the whole thing is awesome.

Your not the only one.

And as far as extended space travel in low G. They have had several designs in sci-fi movies (not star trek) to could generate artifical gravity on portions of the ship.

But we wont go extremely far into space until we vamp the tech up a notch and work out a way to either Build ships in space so they are not limited by the need to breach the atmosphere to get to space. And we can use the Atmosphere breaking shuttles they have to fairy things to and from the ground.

Or another option would be a Large Space Station with Ship builder and a Space elevator.
