Reply to Thinking of space and the cosmos is the only that cures my anxiety. by EarthInteresting9781
I do that too, to be able to fall asleep. Not only it is an interesting thought process but it completely takes away any thoughts about other shit going on.

Reply to Why don’t we see multiple points of light for observable bodies as our planet and the observed body move over millennia, changing their position relative to each other? by HopingMechanism
The light would’ve already passed us. We can only see light that hits our telescope every nanosecond and every nanosecond new light from that object reaches us. We can never determine where in the sky that light started to travel. Our snapshot of the universe is exactly that; the light that we see exists in the moment it reaches us locally but the object it originated from is never in the same position as we see it.

I’m sure there is life in the galaxy. Us finding it in our lifetime is still unlikely. Our radio only exists a hundred years. If other life has discovered radio today but live 1000 Lightyear away, we won’t discover them any time soon. Or if they discovered it 10000 years ago but live 20000 Lightyear away …..

Reply to comment by Aseyhe in How do we know that dark matter isn't just ordinary matter our instruments can't detect? by jmite
There isn’t enough ordinary matter in the universe to account for it all. All the exoplanets and non-radiating matter is only a tiny fraction of the matter we see. And that only accounts for a small part of the gravity we measure. That’s why dark matter is inferred.

Reply to comment by BridgeOnColours in Do 2 objects on opposite "ends" of the universe pull on each other to some extremely minute degree? by Courcy6185
I conclude that every atom warps spacetime and that’s why it can have a combined effect over Lightyears in galaxy clusters. But then I don’t understand why it’s so hard to combine gravity with quantum mechanics?

Gravity does not propagate. Changes in gravity propagate at the speed of light.

No, there is no pull. Nothing pulls anything. Space is warped and that’s why there’s an effect.

Reply to Everyone talks about how huge Andromeda will look in the sky billions of years from now. I present you what the Milky Way *currently* looks like in the skies of our neighbor, the Large Magellanic Cloud. We appear absolutely huge in their skies! [Simulated view] by lampiaio
The people there would probably already have concluded that the Milky Way is not part of their own galaxy but a separate galaxy and that the universe is so much bigger, many centuries before we discovered it.
