Do aliens exist

[D.V.D]

Exactly. The water will still be stored and the solar power would be very unaffective due to the fact that you are moving further away from the sun and that the suns rays are very weak at were the space ship is. The future would probably increase the speed ships move at, not make food grow in the ship. You would also need a couple of vegetarians for the flight who have nothing to do for 2 months.

Lack of evidence should lead to suspended belief.

there is this new engine made which shortens the time taken to reach mars into just like a week or something. So no need to worry about that now.

oh and talking about why aliens will never be able to reach us is because as the universe is ever expanding at the speed of light. Even if the alien travel over the speed of light (which theoretically speaking will cause it to go back in time) it will never be able to reach us in enough time of maybe a few million generations(depending on where their location is though).

Its 1 week with robots. Human weight would still make it much much much longer than it is with robots.

Seriously? Awesome. Link please?

That doesn't seem possible.

errr how does that make any difference?

 

[D.V.D]

Excess weight on the ship. I read it somewhere on wikepedia. Thats why it didn't take so long for the shuttle last year or so to land on mars. Its also because the ship doesn't need so much more space for people making the ship smaller therefore reducing its weight by quite a bit.

 

[Homeboy]

Isn't there no weight in space?

 

[D.V.D]

Yes there is weight in space. There is no friction in space. These are 2 different things.

Not really. Friction is what creates weight; there's mass in space.

 

[Azlier]

There is friction in space. :nuts:

 

[Varine]

There is friction in space. :nuts:

Not really, you're constantly falling basically. If there was friction the ship would be torn apart. There isn't an atmosphere, there aren't a bunch of particles that it's running into it.

There is no weight in space, only mass.

 

[Nigerianrulz]

obviously you havnt got your science lesson on space otherwise you would know that there is no weight BUT the mass of the object is still there.

since there is no gravity in space there is no weight.

Not really, you're constantly falling basically.

i would probably put it as traveling very quickly.. instead of falling

There is no friction in space

umm.. wrong?

Friction is a product of a perpendicular force and the frictional constant of an object.

on earth, the perpendicular force is mainly gravity, but it can be anything.
frictional constant is independent of mass/weight etc.. it's due to the composition of the object.

Friction is what creates weight

Weight is acceleration due to gravity X mass.

Excess weight on the ship. I read it somewhere on wikepedia. Thats why it didn't take so long for the shuttle last year or so to land on mars. Its also because the ship doesn't need so much more space for people making the ship smaller therefore reducing its weight by quite a bit.

Weight is only a problem here on earth. it's a problem because more weight means it's harder to escape earth's gravitational pull to enter space.

 

[Varine]

There's no air, so there's no friction from air, no resistance to moving around freely. However, other kinds of friction still exist, like when two things slide against each other, although if you are in orbit or otherwise feel no acceleration then these things have no weight and don't press against each other like sliding a box across a floor here on Earth. Unless debris or something something hits you there's no friction.

your point being from this post?

 

[D.V.D]

Figured out why people can't go to mars. Its pretty simple. If they go to mars they have a 39% chance of developing cancer when they are in the space ship. Outside, the chance would be even larger. Therefore, they can't send people to mars without actually killing them.

lol, he just randomly comes in talking about Mars.

Nope not randomly, just answering the older post on this page.
