How big is the Earth?!

Apologies if this is posted in the wrong section, I didn't really know where astronomy posts would fit because--well--there isn't many!

I thought that was a really cool video!

Haha, that video really puts things into perspective. Imagine VY Canis Majoris were to collapse into a super or hypernova. It would just incinerate everything within like 50 lightyears. Amazing stuff.

How do they even measure the size of them when they're light years away?

I don't really know. I suppose the billions of dollars our governments spend on physicists must be paying off though

Isn't the world (not just the earth) we live in so amazing?

[Alkaz]

I guess that puts things into real perspective. I think that red giants was big and I was pretty amazed at them super giants.
It makes me think, the comparison between us and the galaxies out there, what could actually be going on right now at the end of our finger tips.

Couldn't VY Canis Majoris be already dead?

Tbh tho, I thought Jupiter was pretty big >;D

It's pretty amazing space. The thing I don't understand is why we always look for water on other planets because it might indicate life. There may be some other element that we don't know about that could sustain life.

It makes sense to look for elements that we know could sustain life before looking for some fantastical element we have no idea about and may not even exist.

Interesting vid!

it's hard to get your head round, even with a video like this, the sheer scale of objects and the universe itself. Just mad!
