Any close by supernova would blow most people's minds away

I understand that now, but we wouldn't need a satellite(even if we have many now). We'd know by the way other objects/planets interact with it

We would be able to measure how other things interact with it. But we have space craft like the Parker Solar Probe, So we do know what on the opposite side to us

Because the volume of water wasn't mentioned, I just thought of a small amount.

If it was oceans of water, it would certainly bulge at the equator like it already does, but it would still have to spread out to find a level.

We see it every 6 months, that's why constellations change depending on the time of year

Sorry, i get what you mean now. There are plenty of craft that can see what we cant from earth

I think it spread out until level. Remember, down is towards the centre of mass

Unlikely, as the influence of gravity doesn't necessarily end, it may just be very very minute

This part ruined it for me, I was all onboard till I read this

*dark energy not dark matter

What about it expanding everywhere at once? and we are limited by light speed so we can onky see X amount. So to us we are the centre but that doesn't mean there needs to be a centre

Put in more normal terms, if you marked out a random cubic meter of empty universe, there’s a 2 out of 3 chance you would have no atoms in it.

Seems like it would be a waste of energy...

What gas? It's near non-existence in the vacuum of space

Well, they exited to the bow of the heliosphere, so I would think the OP means with an exit point heading towards the tail of our system

Given the amount of galaxies, stars, and planets, it is unrealistic that the earth is the only planet where life has occurred. It is, however, very likely that the conditions on earth has happened elsewhere

Or probability.. it's more probable they exist than dont.. coming to visit earth is another story

High probability of starlink. They are close together until separation, and there are also a lot of satellites in the sky nowadays. I rarely go out at night without seeing at least one

A lot will depend on whether a suicide mission is sanctioned or not. If that happens, then end of the decade early 30s.

To do it with more safely involved, maybe late 30s or even the 40s. Trial runs need to happen to see if we can land and take off again, even equipment left there for arrival.

Black holes dont suck. Regardless, it doesn't affect you or likely any of us. That is an unfathomable amount of time away... so basically an infinite amount of life if that's what you believe

Latitude is horizontal and measures your distance from the equator

Also, depending on your latitude, it will affect its apparent angle

>That theory would prove that you could go back in time between universes.

Well, no, because then you'd have to know how to find that other universe.. and if you could find that, then you could find any split of the infinite number of universes and pick the one that suits you most, but then there would already exist a universe where that happened and likely you are already in it.

And if you can find these universes, what is stopping you from finding the infinite number of universes that hold that future by all possible decisions that can be made?

The space race will always be for the wealthy, regardless if that is mining asteroids, moons, etc..

Pretty much all modern exploration has been funded by the wealthy.

The OP said, "I doubt we'll ever leave the solar system" and hence my reply...

The only way we can possibly save our species is space exploration... our planet is finite

150 years ago we couldn't fly, 70 years ago we could leave the atmosphere, 30 years ago we hadn't confirmed any exoplanets, 10 years ago we hadn't pictured a black hole... Does this say anything to you about human advancement...

>However, we would want to study them to see how they evolve so we’d probably scope the planet for years and years

Have you met humans before? History says invasion and slavery are very likely

As for aliens being here and letting us seeign them, it seems unlikely
