Aliens (the space ship kind)

yes they could, but if that was true then they wouldn't be able to visit our planet.

We are capable of interstellar travel, we just haven't done it.


Jim Lovell said it best "We now live in a place where man has walked on the moon. And it wasn't a miracle. We just decided to go."


Unless you believe we faked the Apollo moon landing.

we are capable of space travel, but not capable of long-distance space travel. We are unable to travel to planets with intelligent life on them simply becuase if they do exist then they would be really really far away.

but if a race was 100 or 200 years behind us they would barely be capable of flight never mind space-travel.

No I am not high no I am not drunk... I have the flu and I am thinking off the wall ****.

Admit it, you are high and drunk.

Dawn of the dead, baby. Can you handle it?

Again if we had not just decided to go to the moon, we would never have gone that does not mean we are incapable of doing so. in the 70's we sent probes to pluto for christ sake, supply the food and oxygen we could do it with people too...

There would be NO warp mock 8 Scottie... or Beam me Up... It would be generational trip... A family have kids the kids continue the journey... so on.

Unless you believe we faked the Apollo moon landing.

Erm,....yup.

no i'm not saying we wouldn't go, i'm saying we can't go. it isn't just about food and time, there are a lot of other factors we must consider before we are able to go to pluto, hell we haven't even been to Mars yet as a manned mission.

We have ships built now that can carry enough oxygen and food to the last the several year journey to Mars.

The number one reason why it hasnt happened is because of the fear of something going wrong. You are a year solid travel away from help what do you do?

That is a completely new argument

You posed the potential argument. Make a thread?

exactly, they just built a ship that can carry enough oxygen for a planet as close as mars and yet Pluto is many times further than mars also consider a race that was 100 or 200 years behind wouldn't even be able to do that then how do you expect them to visit us?

WE have the ship for mars not because its new technology LOL... Just because we dont have something doesnt ,mean we CANT make it... it just means we havent.

NASA has a mystery to solve: Can people go to Mars, or not?

"It's a question of radiation," says Frank Cucinotta of NASA's Space Radiation Health Project at the Johnson Space Center. "We know how much radiation is out there, waiting for us between Earth and Mars, but we're not sure how the human body is going to react to it."

NASA astronauts have been in space, off and on, for 45 years. Except for a few quick trips to the moon, though, they've never spent much time far from Earth. Deep space is filled with protons from solar flares, gamma rays from newborn black holes, and cosmic rays from exploding stars. A long voyage to Mars, with no big planet nearby to block or deflect that radiation, is going to be a new adventure.

NASA weighs radiation danger in units of cancer risk. A healthy 40-year-old non-smoking American male stands a (whopping) 20% chance of eventually dying from cancer. That's if he stays on Earth. If he travels to Mars, the risk goes up.

Researchers who did the study assumed the Mars-ship would be built "mostly of aluminum, like an old Apollo command module," says Cucinotta. The spaceship's skin would absorb about half the radiation hitting it.

The greatest threat to astronauts en route to Mars is galactic cosmic rays--or "GCRs" for short. These are particles accelerated to almost light speed by distant supernova explosions. The most dangerous GCRs are heavy ionized nuclei such as Fe+26. "They're much more energetic (millions of MeV) than typical protons accelerated by solar flares (tens to hundreds of MeV)," notes Cucinotta. GCRs barrel through the skin of spaceships and people like tiny cannon balls, breaking the strands of DNA molecules, damaging genes and killing cells.

Astronauts have rarely experienced a full dose of these deep space GCRs. Consider the International Space Station (ISS): it orbits only 400 km above Earth's surface. The body of our planet, looming large, intercepts about one-third of GCRs before they reach the ISS. Another third is deflected by Earth's magnetic field.
