The manhole story is, in 1957 they put a manhole cover over a nuclear bomb which was underground. There was a camera that recorded 1 frame per millisecond. The manhole cover was in only 1 frame. It was estimated to have gone 130,000 miles per hour. Some believe it went into space.
Well. It was actually much larger than a typical manhole cover, I believe it was like a heavy blast shield designed to cover the hole during previous tests. And it was actually traveling so fast that it is more likely that it burned up trying to *exit* the atmosphere rather than how most uncontrolled objects do upon entry, despite the fact the air was getting thinner the further it got. Which to me is... As, if not even more, impressive. 😂
Yeah. It technically wasn’t a normal manhole cover it was a huge circular armor plate that weight a couple hundred pounds to cover the shaft that led down to the bomb
@@chuckwickwire4357 True, the biggest cast iron covers in larger cites are around 250; they can also be as small as 75 lbs. This was called a "steel plate cap", it weighed about 2,000 lbs and was welded to the top of the shaft, so yeah it was a bit more than that few hundred pounds. Believe it was called Project Plumbob.
James, the video did not just repeat the first part in part two. In part one you were moving with the objects hence could not get a sense of how fast it was actualy moving. Part two was you sitting in a stationary spot with the object going past you to show you just how fast it actually is going as it flies past.
3:24 The hypersonic rocket sled was tested at the Holloman Air Force base in New Mexico... Holloman is home to the world's longest and fastest high speed test track. The 846th Test Squadron set the world land speed record for a railed vehicle with a run of 6,453 mph (Mach 8.5) on 30 April 2003.
I moved from Gardnerville, Nevada to Buford/Laramie, Wyoming, four years ago. On the drive to my new home…I passed the Bonneville Salt Flats… So many land speed records have been made/set there. My brain and body reacted as I felt a wave of emotion passing through me…👍🏻

No air resistance in space. Speed increases with acceleration so theoretically there is no upper limit to how fast something can travel in space. Yes the speed of light is the fastest known scale for measuring how fast something goes. And yes all of these craft actually exist.
In reality, since speed is measured from a reference, the voyager probes will eventually be the fastest manmade objects as when it gets far enough away, they will travel faster than the speed of light when referenced to Earth since space is expanding. So they won't travel faster than light in its local space, but from here, they can absolutely travel faster than light. It will take a few quintillion years to get to far enough away, but eventually it will happen, unless the Big Crunch and not the Big Freeze happens.
Episode 1 - you (and the 'camera') are moving with each vehicle as the speed is displayed - and you don't really get a sense of the actual velocity Episode 2 - you are sitting stationary on a hillside and watching each vehicle zoom past - so now you get a better idea of it's velocity You should re-watch episode 2
Satellites go so fast because they are close to the Earth and gravity causes them to move very quickly, they can reach speeds of 20,000mph-100,000mph pretty easily
You guys might like a video by Devin Supertramp where he helped film a car commercial that was a race between an RC car, a guy doing Parkour, and an actual car racing through a storage area for shipping containers. It’s an awesome video.
They do have propulsion on satellites mostly used to maneuver but the end up using other planets gravity to increase the speed of the objects. I think the reference of sound and light are just for reference to the speed of the objects.
I've seen this video, the 2nd half basically is showing how fast each one would be if it was to go in front of you, if that makes sense? Also I think the speed of sound and light are in there for reference, to really show how fast these things are 👍
5:34 This man said "surely that's not man made" when talking about the speed of light lol. It was a reference. The second part of the video the camera was in a fixed spot, giving you another way to see how fast they were going (I can't believe that even needs explaining). Man alive.... sometimes I don't know about you two.
I hate to break it to you all.....but Voyager 1 is now billions of miles outside the heliopause, as far from that boundary as Neptune is from Earth, and speeding onward at about a million miles a day. Which makes this manmade machine the fastest ever
A lot of them are moving faster because they are not in Earth orbit (like the voyager 1 and 2 spacecrafts) are in deep space. In fact Voyager 1 is in interstellar space which means it is beyond the reach of our solar system. Specifically it is 13.5 billion miles (21.7 billion km) from earth right now.
Speeds in space when they are in an orbit around something like the Earth. As you know, when you use a lasso or a rope and spin it over your head. Speed varies to maintain that a lot. But depending on how far you are from the Earth. So satellites depending on their distance from the Earth have to travel at a certain speed to maintain the orbit. So it doesn't crash back to Earth.
They go to the salt flats in Utah for setting the land speed records. About the 2 Voyager's, I think they both have left the solar system now. I think at least one is still transmitting
The space probes use a combination of ionic rockets and gravitational assists to accelerate to those speed. Yes, rockets are used in space. Satellites routinely adjust their orbits with small rocket thruster. Even the ISS has its orbit adjusted using the rocket engines of the Soyuz.
They displayed the speed of light for speed difference reference in comparison to the speed of the satellites. The Parker Solar Probe goes 429,988 Miles per Hour while the Speed of Light is 186,411 Miles per second. The Speed of light is way faster than that Probe. That means Parker Solar Probe can go 429,988 Mile in an Hour where as Light traveling at the Speed of Light can go 671,079,600 Miles in an Hour.
Beesleys, a cheetah isn't man-made either. Some of the things included are used for reference. As far as space, if objects are launched from space especially (say from the space station), size and especially aerodynamics make no difference. What matters is thrust, and usually that would be larger objects. And yes, some are just orbiting, but devices like Voyager are actually traveling in more-or-less a straight path away from the Earth
The land speed record in a jet car going faster than the speed of sound is held by you British. British made car and everything. How do you guys not know this?
I'm curious as to why they didn't include a horse that would have been between the Wright brothers plane and I think it was the cheetah.. Congrats on the new baby. God bless from the Mile High City.
The superfast space probes are the ones that went to Venus, Mercury, or inside the orbit of Mercury to study the Sun ... being closer to the sun they have to travel faster to remain in orbit and not fall closer to the Sun. The Earth itself orbits the Sun at an average speed of 107,000 km/hr, Venus at 126,000 km/hr, Mercury at 170,000 km/hr.
Those arent satellites, Voyager 1 is past Pluto. 15 billions miles away from Earth and has been traveling since 1977. Its the probe that took pivtures of Pluto back in 2015 and goes about 11 miles per second and has reached interstellar space.
A space craft traveling away from Earth typically fights the gravitational pull & slows down. Until it gets within the the gradational pull of something else. Then it can start going faster again. On a trip to the Moon the space craft was constantly decelerating after the trans-lunar insertion burn. Then about 3/4 of the way the moon started having a stronger effect & it started going steadily faster. It is literally rocket science & that is about my limit.
To understand the kind of speeds that they were talking about in this short program, you would have to have a background in the physics of extreme speeds, which takes a long time to educate yourself on if you really are interested in understanding. Otherwise, just take the word of the people who put together this kind of programs, and just go by what they tell you because it takes a lot of knowledge and effort to really understand what extreme speed it’s all about And remember speed like everything else in the universe is relative.
I think the speed of light is 670 million mph or 720 (I forget). Humans have a long way to go to actually fly through the solar system 😭 430k mph is actually super slow… in space🙃😊✌️✌️

Hey funt, seen this as i was replying to your comment on the community. That is just very unlucky timing. we was suggested this a few weeks ago video from someone who had watched it on the new zealand family channel. Didn't know they had done this until i just looked after i saw your comment :D
I don't think they understood what it was from. This isn't an insult to them-it seems that schools don't teach a lot of things that they did when I was in school anymore (I'm a Gen Xer)
I enjoy watching you, but must confess that the video was slightly confusing when it seemed to repeat. For what it is worth, according to google the speed of light is "671 million miles per hour or 186,000 miles per second" and "On a standard day at sea level static conditions, the speed of sound is about 760 mph, or 1100 feet/second. I think one of the things to think about is that space has extremely limited friction, so size is not as important.
It did not repeat per say, they were showing the speed and how it would look going past you when sitting in one place so you could get the feel of what the real speed was instead of what the first time was travelling with the object.

I can see why he changed it though-I think it was to save face for his live-in girlfriend who was getting motion sick
My grandpa was an engineer on the first Apollo.
The second half of the video is worth watching because it shows how fast they go by you if you are stationary.

On Earth there’s air friction. Space is frictionless. Friction slows things down.

I think they used the speed of sound as comparison. Great show, good luck with Baby Boy Beasley! Sending hugs from Texas.

The fastest was actually a manhole cover. Blown off during an underground nuclear test.
parker solar probe is actually the fastest
Nah. Parker solar probe is considerably faster, sun-orbiting things kinda tend to go really fast when they have a low perigee.

Most of those spacecraft aren't in orbit. Voyager 1 is the furthest of any man-made object.

The solar probe...that's relative speed to the sun, essentially.
Thrust SSC was driven by RAF Pilot Andy Green in its land speed record run.
They go to the salt flats in Utah for setting the land speed records.
About the 2 Voyager's, I think they both have left the solar system now. I think at least one is still transmitting
Voyager 1 won't be leaving our Solar System for around 70,000 years (if it can survive that long) Our solar system boundary is the Oort Cloud.
I didn’t know the cheetah was a man made object 😅
I don't know why they skipped half the video.
Before I watched this video I predicted the fastest man-made object would be a space probe and not the military.
I can’t explain all the satellites etc. it would take me a week🤣 I’d recommend hopping on RUclips, and doing some videos on them. 😉✌️✌️
