diba sa movies lagi pinapakita yun folded paper

for example, if you write A on one end of paper, then write B on on another end, then draw a line that connects Points A & B. that is linear travel

then Einstein daw proposed the folding of the paper, and you still you get to intersect points A and B.

Einstein also said theoretically that if we can ride the speed of light, it's like as fast as the folding of paper or folding space.

so why not instead of spending billions on the great starship enterprise, why dont we just study this alternative option.

or do we already have it ...

I have been following the Einstein. his views on Nazism vs. Zionism. his being a german born yet being accused of practicing Jewish physics. and his very convenient migration into the Americas before the start of ww2.

one thing I observed about his studies is his passion for energies & forces. when asked if he believes in a God, he answered this

The question of scientific determinism gave rise to questions about Einstein's position on theological determinism, and even whether or not he believed in God. In 1929, Einstein told Rabbi Herbert S. Goldstein "I believe in Spinoza's God, who reveals Himself in the lawful harmony of the world, not in a God Who concerns Himself with the fate and the doings of mankind." (Brian 1996, p. 127) In 1950, in a letter to M. Berkowitz, Einstein stated that "My position concerning God is that of an agnostic. I am convinced that a vivid consciousness of the primary importance of moral principles for the betterment and ennoblement of life does not need the idea of a law-giver, especially a law-giver who works on the basis of reward and punishment."[37]

Einstein defined his religious views in a letter he wrote in response to those who claimed that he worshipped a Judeo-Christian god: "It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."

if Einstein hated the idea of a God-like law giver who works on the basis of reward and punishment, and he believes in harmony of the world. then how come he issues science laws and theories as well.

for example, if one of his mathematical research/findings contributed to the development of a space engine. then that only means, that if engineers don't follow or failed to follow his computations, then that can be futile. people can get killed or the application itself (such as the spaceship) can self-destruct. hence, a punishment if his "law" is not followed to the letter. a reward if his law is followed perfectly, hence the success of a spaceship. do you think this contradicts what he said about a lawgiver God?

or is it just all for show -> all the complex mathematical computations and scientific naming methods for 97% of humans who won't even bother reading/understanding reading it anyway. basta it's in the name of science, that's it.

===================

now let's take for example the Apollo 13 flight, it was a well-planned/well-computed moon exploration. 2 days after the launch, an explosion happened in the flight. it was the number 2 oxygen tank. it severely affects the oxygen supply of the crew as well as the motors/electricity inside the spaceship. theoretically speaking, they're f3!ked. with one damaged oxygen tank left, they are as useful as a floating lifeboat in the arctic ocean - no winds for them to steer, all ice and cold.

and then NASA & the apollo crew came up with this brilliant idea that up until now still marvels me. The FREE RETURN TRAJECTORY.

To return the crew to Earth as quickly and safely as possible, only a single pass around the Moon was made, in what is called a free return trajectory, which uses the Moon's gravity to "slingshot" the spacecraft back to Earth. To enter this trajectory, a significant course correction was required. This would normally have been a simple procedure, using the SM propulsion engine, but the flight controllers did not know exactly how much damage the service module had taken, and did not want to risk firing the main engine. Therefore the course correction was performed by firing the LM's descent engine, an option settled upon after extensive discussion among the engineers on the ground. The initial maneuver to change to a free return trajectory was made within hours of the accident. After passage around the Moon, the descent engine was fired again for a PC+2 burn (PeriCynthion + 2 hours) in order to accelerate the spacecraft's return to Earth. Afterwards, only one more descent engine burn was required, for a minor course correction.

with a spacecraft short on fuel supply, short of oxygen supply as well as manpower supply (2 were already seriously wounded), they still managed to bag the longest all-time record for human-spaceflight in all history. even Guiness was so happy with this.

As a result of following the free return trajectory, the altitude of Apollo 13 over the lunar far side was approximately 100 km greater than the corresponding orbital altitude on the remaining Apollo lunar missions. This could mean an all-time altitude record for human spaceflight, not even superseded as of 2007;

now, isn't that great. all they needed was a heavenly object like the moon to catch 'em then throw them back at earth.

apollo 13 was already accelerating towards the moon then they used its gravity to give them a "slingshot" route directing them to earth. its indeed ingenius but credit goes to isaac newton this time.
*niky, we're not gonna destroy jupiter. we'll just convert it to a celestial hyrdoelectric dam. once we put in some electrodes in it, we'll use it to power the stargate. about the ring shape space station, it's actually a magnetic rail that will accelerate the ship to 25% light speed so that when it enters the wormhole, it will slow down time inside the hole since time-space is bent(which means, time is also folded or accelerated, but due to the ships near light speed, time distortion is canceled{equationally speaking})

Malalim ang usapan dito baka dumugo ang ilong ko kababasa

[safeorigin]

waaw, ala pa nga sa primera ang usapan dito e. sana may stargate na tayu saka ULTRALOLO spaceship. ahehehe, unang pasahero siyempre mga politikong pasaway.

You have to think in realistic terms... so far, amongst hardcore space science buffs, the idea of a "stargate" seems to lie completely in the realm of science fantasy. The closest we can get is to expand the throat of a wormhole... and that takes an enormous amount of energy.

We would destroy Jupiter to create a singularity that would perhaps give the energy to do this, but it might not be enough.

What we can do (non-destructively) with Jupiter is to harness its enormous magnetic field to power generators or to power said magnetic rail gun to fire interstellar space craft out of the solar system. Given enough money, it's feasible... we don't even have to build the rails... we just need to float the accelerator rings out in Jovian orbit.

Another intriguing idea is Niven's launch lasers... enormous laser batteries installed on the dark side of Mercury, using power generated by solar collectors on the sun-side to shove light-sails out into interstellar space.

----

It's sad that we understand so much about the universe nowadays... the more we know about quantum physics, the less possible it seems that we can leave the solar system at light speed.

Even using traditional chemical rockets, it's doubtful. The amount of energy needed to send a human expedition to the nearest star in less than one hundred years exceeds the total energy production capacity of all current human industries.

We really need space-borne power sources, such as solar power stations before we can even begin to plan exploring the stars.

i thought you'd say that sir, it's not that absurd actually to build stargates but it's a good possibility when it comes to space-time distortion. it's not yet REALISTIC with our present technology. give it some 4 centuries and it may be possible enough. empty space imho is the ultimate testing ground for anything: no resistance, near-zero energy loss and everything is equational. hahaha{if only i could live to see a stargate by that time[sigh]}

[ghosthunter]

I don't remember if it's a R.A.Heinlien story or another author but I do remember a story where the spaceship was powered by nuclear bombs exploding under a "shell" on which the actual "spaceship" sits on. The nuclear bombs are ejected to the middle of the shell and explodes causing action-reaction thrust.

Not that it's practical but its a propulsion system that is not typical.

[oldblue]

why not instead of building a spaceship, we extract each of our universal energies and let it travel by light.

Well, who knows?

Maybe when we get to interstellar space, we'll find out that the lightspeed limit is a lie, and what we see of the universe is censored by alien anthropologists studying us from outside our little bubble of local space.

Nuclear bomb drive... now that's old school.

The so-called lightspeed limit could be a side effect of what we base our observations & calculations from. Personally, I believe it is possible to exceed the speed of light in a "spaceship". The only limiting factors would be energy source for the propulsion system and protection of the "spaceship" against interstellar particles hitting the ship traveling at very high speeds.

well, I loved the storyline where that idea was used. Typical fighting conquering aliens storyline with a liberal twist in the use of technology to fight them on their turf, outer space.
