the sun theory genuinely hurts my brain icl😭😭😭

like if the sun somehow exploded right now, we wouldn’t even know for another 8 minutes???

bro what do you mean i could literally be sitting here watching a movie, eating, or doing whatever, while the sun is already gone and i’m just there completely unaware😭😭😭💔

and i know it’s because light takes around 8 minutes to reach earth, but my brain still can’t process how something not that far away and we’re just chilling like nothing happened

like shouldn’t everything around the sun get affected the second it happens??? how does earth have to wait 8 whole minutes to find out😭😭😭

space genuinely makes no sense bro, this is scripted am i wrong?

Why does science use the argument that the bottoms of ships disappear from view with the naked eye as evidence for a round Earth, and also claim that the Earth is too large for its curvature to be seen directly?

I was thinking about this and wanted to ask people who know more about space whether it actually makes sense.

Imagine money isn't a problem and we can build basically whatever spacecraft we want.

What if we built a spacecraft with a huge telescope and really good cameras and sent it traveling through our Solar System?

Instead of staying near Earth, it would travel past the planets — Jupiter, Saturn, Uranus, Neptune, and eventually even farther out.

The idea is that from Earth, we're always looking at the Solar System from basically the same place. But if we had a powerful telescope moving around the Solar System, we could look at planets, moons, asteroids, comets, etc. from completely different angles.

It could:

🔭 Take extremely detailed pictures and videos.

🌌 Take huge pictures showing the Solar System from much farther away.

🤖 Use AI to help navigate, avoid dangerous objects, and notice things that look unusual.

📡 Have small communication satellites placed along the way so the spacecraft can send information back toward Earth.

💾 And importantly, send the original/raw pictures and videos back too, instead of letting AI decide everything. AI could miss something that humans might notice later.

The spacecraft wouldn't necessarily need to stop at every planet. It could fly past them and use their gravity to help change its direction and continue farther into space.

I'm just wondering:

If money wasn't a limitation, would a giant telescope spacecraft traveling through the Solar System actually give us information and views that we can't get from Earth?

Or is there a major problem with this idea that I'm not thinking about?

I'd really like to hear what astronomers, engineers, or anyone knowledgeable about space thinks. 🚀

Before anyone jumps on me, I get that the big bang wasn't an explosion at one spot. It happened everywhere at once. And I get that space can expand faster than light without anything actually moving through space faster than light. So with that out of the way:

If eternal inflation is a thing, and different regions of space stop inflating at different times so each one ends up with its own hot dense beginning, could two of those regions ever collide? And if ours had already collided with another one, would there be anything left over that we could actually detect, or is it the kind of thing we'd never notice either way?

I'm about as far a way from an expert as can be so apologize if my framing is off.

I have a question (hypotetical). If space is infinity and has infinity amount of planets and lets say we have unbreakable infinite sword. Does that mean the sword is cutting infinite amount of planets just by it existing?

So I want to write a book called countdown from 500 where suddenly one day the sun disappears and I know enough science to know that it’s 8 minutes and 20 seconds but I have a few questions. 1. Could something like this happen suddenly or do I have to make a fictional event? 2. Is earth with no sun habitable for any amount of time? 3. What would happen to anyone on the surface when it disappears and how long would it take for the earth to like freeze over? Thank you science community🙏

Are there planets or stars million of kilometers on top of (or under) the solar system?

What would the necessary force be?

Edit: This is under the assumption that it was geosynchronous.

Hey, high school student here.

If you stir a cup of coffee in space, does the coffee’s motion eventually transfer angular momentum to the spacecraft itself, even if the cup is just sitting inside the spacecraft? What if its floating in microgravity?

IF THERE IS SOMEONE WHO HAS EVER REGISTERED IN OPEN SCIENCE 101 THEN PLEASE TELL ME ABOUT IT!!!!!!

Q. What if i didn't get the questions regarding modules?? whom should ask for doubts?

Q. Are there any lectures by nasa regarding it???

Q. Is there any need of laptop as i don't own laptop....

Q. what will be the timings??

Q. what if i registered now and solve modules after 24 august??

Q. A s a bsc marths (hons+research students), what are the benifits regarding this Open Science 101

In the last few days I read a post somewhere about what would happen if the sun disappeared. I have two questions.

When the sun's gravity disappears, the Earth would leave its orbit on a tangent. My question is this. Would that departure occur at the instant the sun vanishes or would it occur at the time we notice the disappearance, about 8 minutes later?

What would this do to the moon? Would the Earth Just drag it along or would it go off on a tangent by itself?

I'm watching a documentary about the Gemini program, and I've got two questions.

First, if Gemini 6 was intended to launch after the Agena had made one orbit, wouldn't the rotation of the earth have carried the launch facility out of the orbital plane of the Agena?

Second, the RCS tanks were pressurized with helium to ensure fuel flow. How did that actually work, though? How did the pressure force the fuel against the fuel line intake?

I understand that the faster you go the quicker youll get there.

What I can’t comprehend is that if I’m traveling 7000 miles at the speed of light, how do I physically only travel ~1 mile?

Do satellites have mirrors?
