If there is no gravity in space, does that mean someone with a heatproof suit could move the sun simply by pushing it?

>> No.9477905

All of that is wrong.

Yes, but they would push themselves a lot more.

yeah, sure, but to move it even at 1/10 m/s, it would take 1.989 × 10^29 newtons.

If it's mass is huge, it takes almost no force to accelerate it.

>> No.9478790

>>9477930
Exactly. Solarmass is about 2.0E+30 kg; if I, a 60 kg man pushed it, even with 2000 N, it would accelerate at 10^-27 m/s, whereas I would go off in the other direction at 33 m/s.

Someone once looked into Archimedes story, about moving the world. He can only exert small force so he has to move a long distance. To move the Earth a couple of centimeters, turned out he'd have had to walk several lightyears. Probably wouldn't have lived that long even if he hadn't annoyed that Roman soldier.

Simply moving towards the sun movies the sun, before you even get close enough to push it. It'll even move the sun about the same as if you pushed it. All as the result of gravity. You don't just orbit the sun and the earth, but the earth and the sun also both orbit you. Replace jupiter in the pic with you and and the arrow pointing to the barycenter of the sun-(you) system to basically the center of mass of the sun

No idiot, the sun is made of lava, the pusher would simply fall into it and drown.

logically correct
x= no gravity in space
y= move the sun simply by pushing it

1 & 1 & 1 \\

If that were true then all structures in the universe would disintegrate into and the universe would become a static sea of elementary particles.

You are already moving the sun. Gravity works both ways senpai.

Literally everyone else who has commented over the past 2 days understood what OP meant.
>>9483905
That's not how that works at all. You may pull on the sun with the same force it pulls on you, but it has much more mass. You aren't moving the sun at all.
>>9483911
Just because a force is applied does not mean the object moves. In this case the sun would not move at all.

>>9477896
In all seriousness though, no it is impossible for a person to push the Sun.

There is however a megastructure concept that could do the job. A Shkadov Thruster is a gargantuan orbital mirror that is place in front of the sun that reflects off solar radiation back into the sun. This creates thrust that causes the Sun to accelerate and move. So yes, technically it is possible to move the sun, you just need a fucking massive mirror and a lot of patience.

The idea is that
F is so small that f basically=0
M is so large that m basically =∞
0/∞=a
a basically=0
From a mathematics perspective, yes there is a tiny acceleration, but then... HA! MATHEMATICIANS!
