There are many lists of important inventions and technology implementation online. This one is from: Timeline of historic inventions - Wikipedia, the free encyclopedia

The past one thousand years:

11th century
1088: Movable type in Song Dynasty China: The first record of a movable type system is in the Dream Pool Essays written in 1088, which attributed the invention of the movable type to Bi Sheng.[112][113][114][115] In 13th century, Koreans invented a metal type movable printing.[116] In the 15th century, Johannes Gutenberg invented the modern movable type system in Europe.[117]
11th century: Fuel coke in Song Dynasty China: By the 11th century, to avoid excessive deforestation, the Song Chinese began using coke made from bituminous coal as fuel for their metallurgic furnaces instead of charcoal derived from wood.[118][119]
12th century[edit]
1119: Mariner's compass (wet compass) in Song Dynasty China: The earliest recorded use of magnetized needle for navigational purposes at sea is found in Zhu Yu's book Pingzhou Table Talks of 1119 (written from 1111 to 1117).[114][120][121][122][123][124][125] The typical Chinese navigational compass was in the form of a magnetic needle floating in a bowl of water.[126] The familiar mariner's dry compass which used a pivoting needle suspended above a compass-card in a glass box was invented in medieval Europe no later than 1300.[127]
13th century[edit]
1277: Land mine in Song Dynasty China: Textual evidence suggests that the first use of a land mine in history was by a Song Dynasty brigadier general known as Lou Qianxia, who used an 'enormous bomb' (huo pao) to kill Mongol soldiers invading Guangxi in 1277.[128]
1286: Eyeglasses in Italy[129]
13th century: Dominoes in Yuan Dynasty China: The earliest confirmed written mention of dominoes in China comes from the Former Events in Wulin written during the Yuan Dynasty (1271–1368).[130] Dominoes first appeared in Italy during the 18th century, and although it is unknown how Chinese dominoes developed into the modern game, it is speculated that Italian missionaries in China may have brought the game to Europe.[131]
13th century: Explosive bomb in Jin Dynasty Manchuria: Explosive bombs were used in 1221 by the Jin Dynasty against a Song Dynasty city.[132] The first accounts of bombs made of cast iron shells packed with explosive gunpowder are documented in the 13th century in China and were called "thunder-crash bombs,"[133] coined during a Jin Dynasty naval battle in 1231.[134]
13th century: Hand cannon in Yuan Dynasty China: The earliest hand cannon dates to the 13th century based on archaeological evidence from a Heilongjiang excavation. There is also written evidence in the Yuanshi (1370) on Li Tang, an ethnic Jurchen commander under the Yuan Dynasty who in 1288 suppressed the rebellion of the Christian prince Nayan with his "gun-soldiers" or chongzu, this being the earliest known event where this phrase was used.[135]
14th century[edit]
14th century: Naval mine in Ming Dynasty China: Mentioned in the Huolongjing military manuscript written by Jiao Yu (fl. 14th to early 15th century) and Liu Ji (1311–1375), describing naval mines used at sea or on rivers and lakes, made of wrought iron and enclosed in an ox bladder. A later model is documented in Song Yingxing's encyclopedia written in 1637.[136]
15th century[edit]

First modern fixed wing aircraft. 1901: Gustave Weisskopf (Whitehead), a German-American immigrant, is credited with motorized aircraft flight in Bridgeport, Connecticut. Flights were witnessed by citizens and other associates, were recorded in the Bridgeport Herald, a local newspaper, and were the subject of a 1904 article in Scientific American. In 2013 Jane's All The World's Aircraft recognized Whitehead as first to make a manned, powered, controlled flight.

Here is another list of 20 significant inventions in the 20th Century.

   / UFO's... What do you think? #373  
It would be a tall order I think to do it with current technology.

The Voyager space probe travels at 0.00567% of the speed of light. (17 km/sec)

To reach a star 4.37 light years from earth in 50 years requires traveling at 8.74% of the speed of light, or 1,541.45 times faster than Voyager(s) which I think attained their speed by planetary gravity slingshot.

That would require some type of propulsion system. This is a round-up of some other propulsion ideas:
Gallery: Future in Space

I don't think NASA will have any trouble filling the seats for a one-way journey to Mars or anywhere else. Mars One Over 200,000 applied within a short time and supposedly 705 of those are initially viable candidates.

As far as current technology, I was thinking of the Orion nuclear rocket conceived in the 1950's and 60's. It's doable...today...but only if mankind was willing to put the resources into it. We're not there yet...and there are a lot of technological issues to consider other then propulsion.
Here's a bit more: Project Orion (nuclear propulsion) - Wikipedia, the free encyclopedia

Since the topic is UFOs, there is no doubt in my mind life resides elsewhere and some of that life is more advanced then we on earth. Although my heart says yes, we have been visited; my head says "probably not".


Limitations in space travel that we understand (travel faster then the speed of light) may not be the limit Einstein theorized...not to a sufficiently advanced civilization.
 
   / UFO's... What do you think? #374  
My ancestors settled here from the planet 1234 and we don't believe in all that space alien stuff. I guess, we could be wrong...
 
   / UFO's... What do you think? #375  
Indeed my friend. I sometimes wonder if Earth is actually the size of a grain of sand in the grand scheme of things.

Watch "How Great is Our God" by Louie Giglio. This will put our puny existence into perspective relative to the stars above.

I'm positive that our solar system is contained in a small ornamental sphere and worn around a cat's neck.

The cost of a nuclear drive interstellar ship is definitely within the capacity of global resources. The US Pentagon alone spends ~$500B each year, half of a trillion dollars. Global defense spending could support a $3-$4 trillion project spread over a decade without even blinking.

But first of course, humanity would have to stop needing to spend huge amounts on war and war preparedness and direct that to something with lasting usefulness. Doing that requires re-framing our values as a species; we would have to transcend our basic natures.

I'm sure some politician would in effect claim we can't stop killing each other because that would be a "job killer." :laughing:

Our own potential for space travel and what it requires us to do and know is the only measure we have for guessing whether other planets somewhere out there could do the same and resolve similar challenges.

I'm having some gruesome ideas about the one-way Mars adventure. Like--your corpse is too valuable to jettison into space. I think your final destiny would be a compost pile. Truly "ashes to ashes and dust to dust."
 
   / UFO's... What do you think? #378  
Mastering the the fabric of space/time is the ticket...

Yep, that was my point earlier. When we can conquer time we'll have no use for this Planet. Except maybe to come back for the holidays, kinda like going to your childhood hometown.

But Dave, that can't happen. If the U.S. focused the monetary resources required to develop a successful way to escape Earth at the cost of our military budget we would not be the passengers. The passengers would be some thug nation that quietly stood back and waited for the completion date, then stomped out our existence, because we would have no defense system and took our seats.....

I can think of several politicians I would like to send........hopefully.....they won't get the engines started on their return takeoff.
