> being proved wrong

fyi, you forgot to do that part. If you tried, you'd find that there is evidence space is expanding at the current time. But that does not prove the ultimate fate of the universe, obviously. But then again, if you tried, you wouldn't have started this thread in the first place.

seriously, it's weird to see trolls like you in this sub. But hey, whatever makes you feel good inside.

My father-in-law was one of the "runners-up" for Challenger when he used to be a science teacher. I suppose in the end, he could be considered more of a winner, though.

Nuclear powered and nuclear propulsion are two very different things.

Why on Earth would you leap to that conclusion? No. Give it a rest.

Here’s a YouTube link https://youtube.com/watch?v=F55Wtl_AEkY&feature=shares

It could, or it could end today. There is a hypothesis that our universe is a transient state of something else, think of a bubble in a boiling pot of water, and once that bubble floats to the top of the pot and pops. Well, no more bubble.

But there is no telling what type of time scale we are looking at, it's not worth thinking about since we will either die of old age long long before that happens or we will just blink out of existance and won't be here to worry about it anyway.

Here’s a YouTube clip of just the asteroid Asteroid 2023 BU seen shortly before super close approach to Earth - Time-lapse

Edit: my first gold! Thank you kind stranger. I’m glad I can save some time for others

Pulsejets require an atmosphere to operate. By definition they can't reach orbit with a single stage. There's no kind of conspiracy to hold back technology to prevent cheaper cost per kilogram to space or reusability.

Aerospike rockets are a FAR more practical SSTO technology (and pretty reusable, btw). Just never got serious funding because of the intense costs up front.

I'm in VA too but it's been cloudy and raining last week and looks like Into the weekend. Probably gonna miss this opportunity to see it

We pondered this question at the playground when i was about 9 years old. Concenus was that everything would fly off into space cuz the earth's rotation caused gravity. We believed this despite learning the power of centrifugal force on the merry-go-round... where the faster it turned the further we were hurled off it... into a steel fence.

Nah some things are fundamental although being proved wrong isn't arguing tho

Indeed. And if you plotted number of people sent into space instead of launches, the Space Shuttle era would really stand out.

like I said, we have a few billion years to figure it out.

why did you even ask the question, just to argue with the responses? lol.

I've heard about this RDRE, it's a cool concept but I've seen very few details on performance. Does anyone have a number for its specific impulse? Has it been tested in vacuum yet?

Hello u/000genshin000, your submission "Is universe going to live forever?Is there any theory which states that life is going to find a way where life is always sustainable?" has been removed from r/space because:

Ask yourself what does all life have in common? The transfer of energy. Why would the universe have all these methods of displacing/transferring energy if it’s end game is to die an inactive cold death? A big bang is just a lazy man’s theory. What we know of the universe is that galaxies are constantly colliding and recycling each other in this way. We have no idea how many galaxies there are, or what for that matter our own galaxy is heading towards. We don’t know if the universe stretches on forever, or if there’s boundaries. So much to know still.

Big rip or big crunch is disapproved due to fundamental data

Life can sustain itself if there is an energy gradient to be taken advantage of. This includes the possibility of life lasting close to the end of the universe. The point at which it takes more energy to gather resources than you get back is the slow-death line-of-no-return.

Organic life may just be a stepping stone towards metallic/silicon life. In that form life may extend greatly beyond what is possible for organics. Maybe instead of uploading one's mind to another organic body, thereby destroying the host's mind, humanity might transition to a purely robotic existence. I would be fine with that, because our bodies are so easily broken. It would also allow us to go explore the universe without the need to bring the Earth conditions along with us. The most cumbersome, and annoying aspects of a spaceship is usually biological life support. If you had a spaceship of nothing but a propellant system, a guidance system, and the means by which to charge your robotic chassi, that would be a far easier system to maintain in the void of space.

yeah, and one day we will know what those things are.
