@@tbraghavendran ok my explanation is that it's a black hole and it's just at the centre of the galaxy killing the vibe. The stars around it reckon it's a huge drag, like it just really really sucks.
If Black Holes are so massively dense that not even light can escape, gas is always falling onto the Black Hole, and some of this gas heats up and lights up, how can this light flicker like a candle such that it escapes the Black Hole allowing us to then see it? Please explain how this works?
It's not quite correct to say that light cannot escape a black hole. Instead, there is a certain distance from the black hole, called the event horizon, from which the escape velocity is the speed of light. And so, light which crosses into, or originates within the boundaries of the event horizon cannot escape. The light that reaches us was never past that boundary, only very near it.
BTW the “speed” of light is not why nothing can escape black hole. When you cross the event horizon, you could technically have billions of times speed of light or infinite speed (aka teleportation) and you’d still not be able to escape the black hole. This is because when you cross the event horizon, you are literally and figuratively “cut” off from the universe. There is no way for your atoms or information from you to leave that singularity. It’s similar to failing in a vacuum- there is no way for you to change the direction of your fall because there are nothing you can grab or push to chnage your angle or direction.

The black hole at the centre of the galaxy is like a beating heart? 🎵
This won the Nobel prize in physics.
Waiting for random guy to ask to explain all of it in a TH-cam comment
Explain it.

Was this video recorded in the 70s

May be 'cause of spreading of light (at a distance from black hole) whole area seems to be filled with light.

@@Nosirt i have a question since energy can't be created or destroyed what happens to the energy absorbed by a black hole?
@@zmetroplayz2456 it is released via hawking radiation. It is absolutely slow tho. Most black holes will take 10^90 years to evaporate.
Enhance! Enhance!
Did they use the Hubble space telescope to get Sagittarius a what did you want to get like the canned or galaxy?
that light is probably a billion years old by the time it reaches our planet
Actually Sag A is just around 22k light years away from us so the light we are seeing is just 22k years old.
Please hurry up and declare Einstein's theory is wrong. You can observe the stars hesitate as they cross the galactic plane.
