> the only way to test it is with a space test

I have ran some mN scale measurement test. You can do vastly cheaper tests on the ground if you are not trying to extract as much money from investors as possible.

You underestimate mankind. What I'm talking is based on what we know as of today. Not just completely new stuff. It just has to advance.

That's super cool right.

And like a Ring World, a Dyson Sphere is orbitably unstable. A solar flair or three and it's toast.

Not to mention, where are you going to get several Jupiters worth of construction material? All the mass in the solar system, excluding the sun and Jupiter, doesn't add up to another Jupiter.

I will simply comment that we don't actually know how opiates work either. We have a few consistent guesses, but we don't know a lot more than we do know. When I think about miracles, I think about Dr. Szilard and 10% chances.

I believe not, iircc the expansion is a constant (G). In my very un-qualified opinion, removing mass to decrease gravity until the constant is stronger would be plausible... but what would you have left to stand on?

It's just I sorta know it, but wanted confirmation. It's just fascinating yet so surreal, these concepts we haven't even experienced, but we know it happens. It's magic for most people today if they experience it. Like if u r on a black hole and see earth it would be like on fast forward. So then the picture we see of black hole could be accelerated, such that if we are on black hole, it could be something different also? That could also be a possibility right? It's just we see it as black and a ring around it because it spins so fast on its time?

My thoughts go like this when I think abt physics. Mindfuck>fascination>existential crisis>fascination>nihilism>forget and continue life. xD

But in black hole time, that could be just 100 years or something. Meanwhile for us that blackhole to die in earth time would be trillion of years.

Ye i get that, it's just that 1 second near black hole, years on earth. so if u see through a telescope, it would look like people move on fast forward.fascinating stuff.

I like the theory all the black holes will pull the universe back together while forming an ultra black hole and start everything over again lol

Is there some point in the accelerating expansion that the gravity would start to lose? Or would that be unachievable because of something like the Big Crunch happening way before expansion gets that extreme

Great question, since the cloud got really weird from the stacked sky exposures I took it from a single frame and put it back where it should have been before stacking.

Gravity is holding you together stonger than the expansion is pulling you apart. Expansion only wins for really large scales, like between galaxies.

I can't believe I'm watching a video recorded on another planet than ours.
Mind blowing

EM drive was a false positive from uneven heating.

People were indeed surprised, although I’m wondering if a very high altitude dark haze layer would be able to cloak signs of carbon dioxide, which the paper notably points to the lack of, and mimic airless body.

It shows that not all of the planet is red - this bit's more of a dusty brown, as is much of the footage I've seen.
