Fun Space Facts & Theories! (#2)

Hello peoples!
This is a post covering facts/theories/hypothesis' from different time periods and across the world. Whether they're upheld, debated, or false is up for you guys to use critical thinking to figure out or a simple google search to look up if its upheld or not.
This information is accurate as of October 7th, 2025.
Always remember to do your own research and have an open mind and, even if its just a single google search to Wikipedia, that's enough as long as it isn't an A.I Summary!

Number 1:
The triple-star system WR104, with a red giant type star 8,000 light years (4.7 quadrillon kilometers) away holds 25 times the mass of our Sun (25 Solar Masses). When that red giant dies, it has a small chance to emit a beam of radiation out 2 equal points of the star. And in this burst, it will emit more energy in the span of a few seconds than the energy emitted by our Sun throughout it's entire lifetime. That is incomprehensible for the human mind. I'll still label a numerical comparison either way. Every second, the sun produces 3.8x10^26 joules of energy PER SECOND. However, over the course of 5.5 billion-or-so more years, when Neptune is the only planet that most likely won't be BOILING (water-wise) and its icy moons have melted and turned into planet-orbiting comets, the Sun will have emitted 2x10^45 joules throughout its entire lifetime by the time it dies.

Number 2:
The Solar System, contrary to popular belief, is a system very lucky to be as stable as it is for an 8-planet system with 4 terrestrial/rocky/small worlds and 4 gas giants. For reference, removing a mass as small as Earth's would cause Mercury to either crash into the Sun roughly ~3 billion years into the future or collide into Venus in a bit less or more time. Additionally, Venus' and Mercury's orbital eccentricity would go crazy and be unstabilized (0 = perfectly circular orbit, 1 = no orbit, escape trajectory.) This is due to the fact that the Earth has more mass than Venus, Mercury, and Mars combined. Earth is the glue that holds the inner 4 terrestrial planets together.
Removing Jupiter would cause the inner asteroid belt to go haywire and the asteroids would start merging and be uncontrolled and all over the place, and the inner planets and possibly Saturn and (potentially) Neptune would be struck with far more asteroids than there would be if Jupiter were there and Jupiter is basically the "big brother" of the planets and keeps everything in check.

Number 3:
78,000 years ago, a time when modern human (evolution-wise) humans were around, a Red Dwarf star known as Scholz' Star and its Brown Dwarf companion might have grazed the outer edge of the Solar System and its closest approach being roughly 55,000 Astronomical Units (5.1 trillion miles/8.2 trillion kilometers). Scholz' Star most likely would've never been seen by our species' ancestors nor any other hominid cousins of ours at the time that hadn't gone extinct. However, due to Red Dwarfs (especially young Red Dwarfs) being active flare stars and getting less active as they age, and although the age of Scholz' Star is unknown, it could potentially be a young star and the bright flares could've been seen as red flashes in the night sky from Earth.
