I watched it three times wondering how there was a fireball on the moon
So awesome and so terrifying at the same time
Deleted. What was it?
It's not deleted, just click the Reddit icon in the top right and it'll load
I'm really torn here guys.
That video looks pretty globe-y but I was told by my flat earth boss it looks curved due to a cat eye lens on the camera.
That’s the only pic I’ve ever seen that makes Earth looks like it has celestial dick lol.
The moon, or, Space Brazil
In line with @Shinzon itblooks like something very ominous is trying to fuck brazil
Maybe Ra tea-bagging Australia?
What is the thing in between them and earth?
8 minutes to lift off
Here is the launch from UCFs stadium. I love having our 50 yard line directly lined up with the launches.
That's fucking cool.
Need to schedule a launch during a game. Fuck a flyover, do this.
That would definitely be the ultimate, night game with a launch, so hard to do but imagine that during a national broadcast, would be the ultimate TV moment
But how do they do a long exposure photo live on TV?
And the caught the falling booster rocket with a helicopter with a long ass rope and hook on the end of it, amazing.
They used to do that with spy satellite imagery
As a kid, I used to think a black hole was like the stellar equivalent of pulling the drain in the tub, where it slowly draws in everything around it, sucking it down into the endless abyss, growing larger all the time, eventually to consume everything.
Turns out they're more like pools of quicksand. Just go the long way around them and you'll be fine.
I could listen to her talk about space for days…
I’m loving her reaction to movies clips.
Lunar eclipse tonight in north Orlando
yeah that was very cool, I watched from about halfway through to totality while I was out walking the dogs.
Someone drop some acid on my tongue and explain this apparent "universe expansion appears to be increasing" phenomenon to me.
I think the best way to think about it simply (I use that word EXTREMELY loosely) is to think of the universe as a balloon being inflated more and more. If you draw a few dots on the outside of a deflated balloon and then blow it up, the dots get further and further apart from each other. That's expansion.
Here's where it gets tricky (I think). The dots on the outside of the balloon are 2-dimensional as they are growing apart. Now imagine there is glitter floating around inside the balloon; this is the matter in our universe which is 3-dimensional.
To add a further monkey-wrench into thinking about it, the closer you get to the inside of the balloon skin, the faster it keeps retreating. The universe is 4-dimensional, and right after the Big Bang there was a hyper-small moment when the universe grew faster than the speed of light. Since space & time are unable to be isolated by themselves, the further you travel in space towards the supposed "edge" of the universe, the farther back you go in time.
Today, I think the most accepted theory on the end-fate of the universe is that it will continue to expand infinitely, with all matter becoming further and further removed from each other. With redshifted galaxies continuing to race away from us, they will eventually appear to wink out since the light leaving them will be travelling slower than the expansion rate.
Thanks for coming to my TED talk.
Man, that's completely awesome that you took the time to type all that out in a way that's (fairly) easily digestible.
I believe the universe did not only briefly expand faster than light, but is currently expanding faster than light. It’s allowed to do so because things can’t travel faster than light in space but nothing stops space itself from expanding faster than light. Or something like that.
I saw a great video on the speed of light the other day. Basically saying how we can't measure its actual speed, we can only measure its round trip speed. The fact that earth, the solar system, Galaxy ect is all in motion means the time we experience is reletive to the direction we are moving in space, and light can actually be going faster in one direction than the opposite return direction.
The expansion theory is the most existentially depressing thing you can imagine if you follow it to its conclusion
For sure, but even if it’s right and you could download your brain into a computer before the death of your body you would live for longer than the universe has already existed
the big rip is infinitely depressing
And the big crunch is nice because everything becomes a single point again and possibly start over
