If humanity(or an evolution of it) survives the expansion of the sun, then the contraction and death. I would be a little surprised.

That's in 4 billion years or so.

Heat death is trillions of years away. If any ancestor of modern humans exists at that time, I'm sure they'll think of something.

Assuming heat death is the destiny of the universe. I think until dark matter and energy are better understood, the assumption the universe will continue expanding infinitely should be taken with a grain of salt

Oh for sure they would, but it would just slowly influence it a tiny bit over huge time spans(unless it is jupiter size and closer to earth than mars or venus). The star is going to be a much more powerful pull than even that would be.

Hahaha maybe one of the planets woulf eventually find a home as a moon of it though

The universe is essentially infinite, but I'd argue that's not enough for the chances of two identical mass and size bodies to form right beside each other and have a stable binary gravitational influence WHILE orbiting a star.

They would most likely collide(possibly like how proto earth collided with a similar proto planet which ejected the material that became the moon).

The problem is as they neutrally orbit each other, one would be closer to the star and feel a stronger gravitational tug, while the other planet would be pulling against(which would be in constant flux due to their changing position to each other relative to the star) and quickly lose stability

Basically to an outside observer, you'll never see it enter the blackhole.

Time at the event horizon from a distant perspective is basically frozen.

The "glow" around the black hole, or the event horizon, is basically our view of everything falling into it, but from the perspective of whatever is falling in, it has already been consumed.

That's not entirely accurate, as it will technically stop being visible to an outside observer eventually, but we're talking an insanely long time period so you wouldn't be able to watch it happen

It is an unbelieveably BAD idea.

Daniel Johns tattoo choices level of bad ideas.

Not sure where you heard it, but aus is not by any means considered a strong country for powerful international law firms.

More specific to "space law", that is entirely under the UN's domain. If you're thinking stuff like astroid mining or resource extraction from moons/planets, that's not a real thing or issue that will be happening in your life time. You'd be much better off trying to put your electrical engineering knowledge to use creating some sort of bubble with such a strong electromagnetic field it can accelerate you to near the speed of light and let you skip a few hundred years into the future.

What about astronomy? Aus is a great country in that field.

Don't change your life plans yet. If most of the class failed, then don't worry about it. If you fail the course take it again. Ask any math or compsci major about the discrete mathematics course. I once had an astrophysics course that only 3 people passed. The final was determining the mass and orbit of an exoplanet observed from earth based on a stars wobble profile using nothing more than a pencil and basic graphing calculator. Fun times. I'm pretty sure they've changed the curriculum since then, so don't let that scare you off lol
