MARS and back in 2 days...

Well, speed of light exceeded...
... they showed once again what we already knew: that quantum entangles particles
appear to "communicate" their states instantaneously.
This does not at all mean there must be anything "traveling faster than light".
It does mean that entangled particles are somehow in direct contact despite their
relative distance in space. That doesn't need any true "faster than light" travel
through that space, it just needs a slightly more complex dimensional system
where quantum entanglement is "communicated" via another dimensional axis
than those involved in movement through the 3 dimensions we call space.

Look at it this way: if we could teleport a person to Alpha Centauri instantly,
so that the person dematerialises here and rematerialises there at the same time,
would we call that "faster than light travel"? Nobody actually makes the journey through
space to Alpha Centauri... Nobody actually travels... the person just pops into
existence there... So is that "space flight" and "FTL travel"? Doesn't sound like it to me.
Yes, the person would have changed position with such a distance to time ratio
that it would not be possible to do it by actually physically moving through space at
very high velocity even for photons, and if the person had indeed moved through space
with such tremendous speed the person would indeed have traveled faster than light.
But the person never does so. The person never moves through space at high speed,
the person simply disappears here and re-appears there at the same time.

This is what such entangled particles do: they "teleport" information. They never
communicate that information by sending packets of particles with the encoded
information to eachother, they don't use matter traveling through space to communicate,
and so their communication doesn't really travel through space at the speed of light.
Yes, their communication does occur instantaneous and that is faster than would be
possible if they did use communication that needs to traverse space to get to the other
particle. But since that is not what is happening, there is still nothing moving faster than light.
So even though "spooky action at a distance" does appear to happen faster than light
could traverse that same distance, there is nothing actually physically traveling faster
than light through space. And so it is not FTL. One cannot make a spaceship fly faster than light,
even if we could somehow utilise quantum teleportation. Yes, effectively one might be able
to get somewhere by teleporting a lot faster than light ever could, but you would never actually
move faster than light through space. I guess you'd have to move through subspace of hyperspace
or something like that, circumventing "normal" spacetime, to do something like that.

I think solar sails( though slow) would be enough to get from from planet to planet.No fuel weight,just the pressure of sunlight from the sun to mars.Then from mars to saturn use concentrated sunlight and
liquid fuels to get around.Once you can get out of earth's gravity field.You would be able to travel the solar system using the sun's energy from the sun to Saturn and at least orbit the other planets.Chemical or nuclear rockets when you leave or land on a planet.I just saw another movie where you have one spacesuit and three men.But all three have to leave one ship to get to the other.Why not have barrels that a person can fit into?With handles?So the one guy with the suit can see that the other two gets into the airlock OK.No one goes floating off into space.Beyond Saturn we would need to use nuclear rockets.This are the tools we have now.Triffid

I stand corrected.There are some good videos on solar sailing on u-tube.They are able to take us clear out of the solar system to nearby stars.I thought they were only good to get to mars with.Triffid

OK, silly idea to get some SPEED, from gravity.
There's plans to attached a wire between moon and earth, right? And both vary in distance quite a bit, correct?
Use the wire as a cata pult. Built properly, it will work. Launch from weightlessness, without air resistance.
Catapult maybe be the worng term. It will be like two people holding a wire across the room, it laying straight along the floor. An inverted V shaped object stands over the wire. On 3, PULL. the launch speed will be faster than the pull, and this is even against gravity. So imagine in "empty" space.

Any volunteers to take seat in the catarocket until we figure of a way to dampen the triple digit G forces?

I like the idea of a wire attached between the moon and the earth.But for two reasons it may not work.First, there is too much stuff in orbit around the earth right now.Something will bump into it.Second,the earth moon system is constantly moving apart.A benefit might be that large electrical energies could be generated promoting travel for free between the earth and moon since the universe and sun,etc would be generating the power.Triffid
