- 字幕依据：We welcome you on behalf of the inhabitants of the earth. Hello from the children of planet Earth. And more than 100 images expertly chosen by Carl Sagan and his team to tell our story, the human story, Earth's story. Now, before I show you this picture, I want you to take a deep breath because it's honestly pretty terrifying.
dSgP3J4fD6U@2:37 - 字幕依据：And Henson even partnered with a medical imaging startup to measure the redness and razor burn when using the Henson razor versus a leading multi-blade brand. And I mean, the results speak for themselves. Now I have used safety razors like this for the last few years now, and I can be honest and say that this is genuinely the best one I've used.
dSgP3J4fD6U@6:35 - 字幕依据：the immense Cosmic ocean here resides everyone you ever knew every human who ever lived every story that was ever told it's where our journey begins but as we zoom out beyond our atmosphere past the moon Beyond The Familiar planet and the sun we embark on an Epic Quest a quest to grasp the true scale of our universe as we leave Earth's embrace the first marker on our Cosmic journey is the moon about 384,000 km away a distance so vast that if you were to drive a car at a constant speed of 100 km per hour it would take you over 160 days to reach it and from this lunar Vantage Point Earth appears as a a fragile sphere of Blues and greens cradled in the black void of space a sight that puts our existence into a humbling perspective this is Earth as seen from the Moon as we continue our outward Journey the next Milestone is the sun lying approximately one astronomical unit away from Earth this unit equivalent to about 150 million kilm is the standard measuring stick for distances in our solar system imagine this light traveling at an astounding speed of 300,000 km/s takes about 8 minutes and 20 seconds to Journey from the Sun to Earth if you were to travel this
pSHVbLPWA28@0:14 - 字幕依据：distance in a commercial jet flying at 900 km hour it would take you about 19 years this immense distance is a stark reminder of the vastness of space even within our own solar system the Sun a fiery Behemoth provides life- sustaining energy to our planet from this incredible distance venturing beyond our home planet and its solar companion the sun we set our sites on Mars our enigmatic red neighbor Mars at its closest approach to Earth is about 54.6 million kilm away however this distance can stretch up to 401 million km when the two planets are on opposite sides of the sun to put that in perspective traveling to Mars at the speed of a commercial jet would take upwards of 50 years this vast expanse of space between Earth and Mars has been a significant challenge for space exploration The Rovers and probes we've sent to the red planet embark on a journey that is not just far but fraught with complexities due to the constantly changing distances and orbital Dynamics as we journey to the outermost reaches of our solar system we encounter Neptune the distant ice giant lying roughly 4.5 billion kilm from Earth Neptune marks the edge of our solar
pSHVbLPWA28@1:42 - 字幕依据：neighborhood sunlight racing across the vacuum of space takes about 4 hours and 15 minutes to reach Neptune from the Sun this staggering distance showcases the enormity of our solar system launched in 1977 the Voyager One space probe represents Humanity's insatiable curiosity and our desire to explore Beyond known bound boundaries as of now Voyager 1 has traveled for over four decades covering a staggering distance of more than 22 billion kilometers from Earth it's the farthest human-made object from our planet a silent Wanderer in the cosmic sea in 1990 at the suggestion of the renowned astronomer Carl San Voyager 1 turned its camera back towards Earth for one final photograph this resulted in the iconic pale blue dot image and at a distance of about 6 billion kilm from Earth our planet appeared as a tiny faint dot in the vastness of space Sean poetically reflected on this image emphasizing our responsibility to cherish and preserve our only home a small Speck in the immense Universe At the very fringes of our solar system lies the ort Cloud a vast theoretical sphere of icy objects this distant cloud is thought to extend up to a
pSHVbLPWA28@3:05 - 字幕依据：staggering 100,000 astronomical units from the Sun that's about 1.9 light years a distance so immense that it's on the cusp of interstellar space scientists determine the boundary of interstellar space known as the heliopause where the sun's solar wind is stopped by the interstellar medium this is where the influence of our sun ceases and the vast realm of interstellar space Begins the or Cloud represents the final frontier of our solar system a boundary Zone where the sun's influence wanes and the cosmic journey into the Galaxy truly begins as we venture beyond the confines of our solar system our next point of interest is Alpha centor the closest star system to our sun located about 41.3 trillion km away this distance is equivalent to over 276,000 astronomical units at such colossal distances the AU a measure so convenient within our solar system begins to lose its practicality hence astronomers use the Lightyear the distance light travels in one year for Interstellar measurements Alpa centu is about 4.4 light years away from us considering our current space travel technology a journey to Alpha centor is almost unfathomable
pSHVbLPWA28@4:28 - 字幕依据：for instance the Voyager spacecraft traveling at about 17 km/ second would take over 70,000 years to reach this neighboring star system this immense distance underscores the vastness of space that separates the stars and highlights the challenges of interstellar travel our journey now takes us to the Grand scale of our home galaxy The Milky Way spanning about 100,000 light years in diameter this vast spiral galaxy is home to hundreds of billions of stars each potentially hosting their own planetary systems within this immense structure there's a a tiny sphere known as the human radio bubble extending about a 100 light years from Earth this bubble represents the farthest extent of human influence in the cosmos the reach of our radio and television broadcasts into space beyond this bubble it's as if Humanity never existed any civilizations residing in the vast majority of our galaxy would be oblivious to our presence given that our signals haven't reached them yet the scale of the Milky Way is so vast that our entire recorded history is but a whisper in the Cosmic Wind undetectable Beyond this small bubble as we leave the Milky Way we enter the vast almost incomprehensible realm of Intergalactic space here galaxies float in the
pSHVbLPWA28@5:52 - 字幕依据：cosmic ocean separated by mindboggling distances our galaxy is part of a small Cosmic neighborhood known as the local group a cluster of more than 50 galaxies spread across approximately 10 million light years the local group is a diverse assembly including not just spiral galaxies like the Milky Way and Andromeda but also a multitude of smaller dwarf galaxies the distances here are so vast that light from one end of the local group to the other would take 10 million years to Traverse this scale dwarfs anything within our own Galaxy underscoring the enormity of the universe Intergalactic space is a silent expanse a vast Wilderness between the islands of Galactic light in this immense void our galaxy home to our entire history is just a tiny Speck among many a single story in the grand Cosmic Library as we extend our Cosmic gaze beyond the local group we encounter the Colossal Virgo supercluster an immense collection of Galaxy groups and clusters including our own local group encompassing a region of space about 110 million light years in diameter or 33 megap parex the Virgo super cluster is a Titanic structure in the universe containing thousands of galaxies from at least 100 Galaxy groups and clusters each with their own Myriad stars and planets as we journey
