Oddly enough, I too was in that dream and mine was damaged. I had to have extensive surgery from the Venutians to have it repaired. Nice bunch of aliens those guys. Don't know who won though as the battle was over before my surgery ended.
David, you're a poet. I have never seen a physicist describe the universe so eloquently and poetically as you do. Thank you for these videos. Keep them coming.
Thank you so much for sharing such fascinating videos about the mysteries of the universe! I'm always in awe of the wonders that exist beyond our planet.
This channel truly stands out for its exceptional quality. The depth of information and presentation, especially at the 43:35 mark, is incredibly impressive. It’s amazing to witness such valuable content being shared in today’s digital age
Very impressed with this video. I have always been interested in astronomy and physics. It was things like this that drove me to enter those professions. Thank you for feeding my insatiable curiosity about the universe and the wonders that we discove
It's not a 2 or 3 hour documentary buddy, it's multiple episodes of The New Frontier joined together. This 'Spark' channel is excellent but it's the Kosmos channel here on TH-cam that makes the long two hour plus space documentaries.
i think its for sure clock itself... but the technical question is how do we differentiate clocks mechanical dymacis difference is because of times dynamics or its because of forces affecting the clock ie out of ... anyway i suspect that this might be something about mass... ie for example non magneting matter when enters a magnetic area or electomagnetic are... ie think about transformers.. when secondary offline coil enter a electromagnetic area it gains energy.. similar protocol applies for magnets too ... which makes me wonder is possible that some kind of force affects matter on denser places... and if things distance from them and by moving rotating you are getting out of sync with local power source and therefore that force being influencign less the moving ones may be the reason making moving clock work slower... so it may be just the thing tht powers universe powering less the moving objecs :D just a guess. :D
Trying to emotionally affect your mind, to distract you from the pointless science they claim to research on planets that billions of human and other life forms on earth don’t give a hoot about. In short more funding!
Who si the narrator? I used to see a lot of things with his narration but cant recall them so if I knew his name I would be able to look em up. About 1 min in...that voice
You can't have a seismometer until after they're done doing all the digging further underground bases now after all these years they're finished you can have one
"Venereal" would indeed follow linguistic rules, but "Venusian" has become more widely accepted to describe Venus-related phenomena due to common usage over time.
The detected pattern of excess abundance of Uranium and Thorium on Mars surface, relative to Mars meteorites, can be explained as due to two large thermonuclear explosions on Mars in the past. - John Brandenburg (Morningstar Applied Physics LLC)
IKR? Why can't we just send AI to mars first? Robots could get it ready for us.. Instead we have volunteers ready for a big dose of radiation right off the bat.
she obviously does´t get the point here. when everything is connected,, the main question is, who pulls the strings? power is the one who, who holds the key? that´s the major concern... humanity is always doing, but like in half life: "unforseen concequences"... think ahead ... one time... please.... peace out.
Its good private companies are getting into this area ( if left to NASA it would be 100 years ) NASA is spending large amounts to go back to the moon - something they did ?? 50 years ago? They could have had a a moon base 40 years ago built by remote controlled construction vehicles. First movers will benefit from the moon! so go for it!
These people are supposed to be the smartest people yet anyone with a little bit of common sense would know we will never be on Mars in the near future or in the next century as they can’t even make a desert 🌵 into a place humans can live so if they can’t do that living on a planet is a joke. Also we have Earth.
Amazing we can get there but is nobody willing to aknowledge whats been happanung here in regaeds to ufo/uap tech in our own atmosphere and low earth orbit? 😂😂
Its been discussed and investigated again and again for decades and there is ZERO evidence for anything extraterrestrial here on earth. This is a science channel not a conspiracy theory outlet for gullible people
I'd say less, it's becoming more and more attractive to get out to space and with so many people who want to take part and even invest in getting there I think it will happen sooner than later

Was Uranus damaged?

Yes 😁

The background music is irritating sadly. Turned off

Carl said many decades ago that Venus should be described as being 'Venereal' not "Venusian" so that is how I describe her, _not_ "Venusian".
"Venereal" would indeed follow linguistic rules, but "Venusian" has become more widely accepted to describe Venus-related phenomena due to common usage over time.
