A new Earth?

If you study fizics you would know the human body would be crushed like a tin can at even a 10th of that speed. We do not have anersha dampers.

so we invent them.  along with alot of other stuf we need for this journey.  like co2 recyclers(or better yet a ton of plants)

"invent them" I did not ever think I would say this you woch to much star trek. You should read the fizics of star trek by Steven knockings.

As I think that this planet is the object in space which will come into major focus they are going to launch a  "probe" to it in the next couple of years before launching any kind of crewed mission. How long do you think will it take with the latest engines technology to reach this planet?

100 years give or take a decade

Adama man,
It takes "us" seven years to get to jupiter; around eleven to get out of the solar system: why did you choose one hundred years to get to this new planet? (the solar system is 79 AU's across: around 8 light HOURS in diameter). Given that we even manage to go twice as fast (even though the speed of these spacecraft would kill our astronauts/cosmonauts) the journey to a planet 20.8 light YEARS away would take 24,125.64 years (that's twenty-four THOUSAND years)

The Question
(Submitted February 11, 1998)

I am 8 years old. Could you explain what a light year is and give an example that I can understand or relate to.


The Answer
A light year is the distance that light travels in one year. The speed of light is 186,287.5 miles per second. You can find out the number of seconds in a year by multiplying the number of seconds in a minute (60) by the number of minutes in an hour (60). Then multiply that by the number of hours in a day (24), and multiply that by the number of days in a year (approximately 365.25).

  So we've got 60 x 60 = 3600 seconds in an hour
              3600 x 24 = 86400 seconds in a day
              86400 x 365.25 = 31,557,600 seconds in a year.

So a light year is about (I've rounded off a bit) 5,878,786,100,000 miles. That's almost 6 trillion miles. The distance from the earth to the Sun is 93 million miles. The distance to the nearest star is 4.3 light years, and the distance to the Andromeda galaxy is 2 million light years.

The universe is a big place !

he mustve missed the part were it said"please put this into terms an 8 year old can undersatnd".  I didn't learn multiplication unltil 3rd grade! as to Dominus noctis.  it was an (uneducated) guess

Well its on NASA home page that tell you he is not dumb kid. The 8y old Jim Lochner mst be some kinda prodagy.

you missed it.  an 8 year old was asking the question. while NASA responded with the gibberish

Well The responder may no have had thare stario engections yet. Those pepole are over worked I whould nt be abule to type if I had thare job.

Sorry 'bout that Admiral , guess I didn't have my midday cookie: I wasn't trying to be a jackarse, I just thought it was kinda funny as whenever we talk about other planets we sort of assume we can see and visit them in any reasonable amount of time. (Even Alpha Centauri is 4.3? lightyears away)

on another note.  what about first colonizing this solar system.  much easier(relatively)

posted on May 2nd, 2007, 11:35 am

well other than mars & our moon, what else is there to colonise?

posted on May 2nd, 2007, 3:00 pm

The moons of Jupiter and Saturn, Titan in particular.
