Still waiting for the part where he explains how radio telescopes work... 🤣

[johnp.]

I'm just wondering how do you get images from that thing without a frigin' scope

[TheRuffusMD]

radio telescopes can see though the dust of distant galaxies, and i have read the atmosphere really does not effect them, in fact they can operate on a cloudy day, thus why are they placed in chile , at the highest altitude possible, since the atmosphere has little to no effect

Videos like this is why aliens won't talk to us.

[randombits]

Rest of the video will be seen only through radio telescope

That was probably the worst and most incomplete explanation that I've ever heard. This can't even be classified as "for dummies" b/c this is less than. Do better! One minute I'll never get back!

I really wanna pursue astrophysics at UCBerkeley :( But im indian and i did bad at geography in 10th grade.

How much does it cost to build radio telescopes like the Allen Telescope Array? Seriously can't be cheap and difficult to find funding and donations

[loudandlearnt]

Clear and concise! Thank you for using the radio as an example.

How das radio telescopes like the meerkat radio telescope in northeh cape see new galaxy???

[eventfulnonsense]

This one I've known recently;
One doesn't actually "listen" to a radio telescope 😂.
It doesn't work that way 😂

[malinkang]

I heard this sound while I meditation.

[madgigahz]

you can tune a dial, but you can't tuna fish

[urandurparthu]

Then why don't we put the radio telescope in space just to observe black holes
And maybe with some kind of filters that don't pick up a radio signal from earth

[safedisk]

wir denken zu gradlinig. was ist wenn aliens dies nicht tun? was ist wenn signale auch 3D sein könnten und in mehreren signalen ausgestrahlt werden können quasi 1 signal nur in 3D halt?

[fibiger]

Maby aliens dosnt listen to the radio???
Please explain what would transmit a radio signal, that can be picked up.

[ALASKASCHOICEMUSICVIDEOS]

If you’re going through hell keep going

[devarmont]

How is the title "how it works"...
You failed to explain anything

[PatriceSerapiglia]

👽It’s amazing that so called smart intelligent people think that aliens civilisations use 21st Century earth technology radio waves to communicate. Seriously?👽
