Black Holes Existence Debated by Astrophysicists | How the Universe Works | Science Channel

[Kallisto.]

This must be old because we have 2 pictures of black holes; one of M87 and one of Sagittarius A* at the center of our galaxy...

[CartoonHero]

I really wish you guys would put the season and aired date on these. Yes you clipped and posted it today, but this is from a season of How The Universe Works that is nearly 11 years old and has some outdated assertions and data. The main point of this video is "we know they exist but we've never imaged one directly" but we directly imaged a black hole about 6 years after this episode was made.

This is an old documentary from 2011, before the Event Horizon Telescope images

[berfranper]

This has to be old, but was uploaded on January 8, 2023. We already have pictures of M87 and Sagittarius A*. Don’t upload obsolete information.

[Xenrel]

Yeah I know it might sound like a little thing but I don't support misinforming people. Do correct this video.

"Gravity is so weak" Lawrence Krauss

Yay, now I'm anxious about flying off the planet again. 😅

[malibustacy]

Says January 8th/2023 on the date stamp and that's my birthday, so perhaps we should be talking about a special pizza night out for me...nobody could be more deserving, I'll be having a multi topping special with extra cheese so call me asap and don't keep me waiting.

But which scientists dispute the existence of black holes, as the title claims? The video focuses more on the nature of black holes rather than the controversy indicated by the title. 😡

Also, the information is outdated. This video made me lose my respect for this channel.

[abstergoagent]

I swear the voice over dude sounds just like mark meer the voice actor for shepherd on mass effect I swear every time I play that game it makes me think of this 😂

[lucash]

No legitimate physicist questions the existence of black holes.

[marineforces]

… use language for what it’s for : the thing u vlog about is not even a hole !

[nataliep]

Everything makes sense.. But at the same time, nothing makes sense.

[Friedbrain]

They show the hole as a big thing but that is wrong. If they exist then we can not see them only the effect of them in the neighborhood. I guess gravity is a 2-dimensional thing because otherwise, our solar system would be a ball type system and not a disc system.

[davidmelies]

Wait, we have seen one. We have photos so umm...

[mr.grantelkade]

Came for science and debate, but there was was fancy graphics😢

[abdallaalmidfa]

How dare those arrogant astrophysicists claim that they know everything in the universe, they should know their limits, take for example the age of the universe and its boundaries and the Big Bang theory and black holes etc .

[glennlao]

Black holes are the vacuum cleaners in space without them theres no cycle in space

[defeatSpace]

Black holes aren't black, you muppets! They're unbelievably bright points in space of infinitely dense particles hidden by invalid vectors.
