Scientists have disproved movie myths about space
Filmmakers love to argue with scientific facts.
Space is not only astronomy and related sciences … The boundless and unexplored distance attracts an inquiring human mind. Therefore, it is not surprising that there are many popular films about space. And often quite deliberately – for the sake of a good picture and emotional sound.
Explosions in space
A powerful cosmic explosion on a large screen with a high resolution – who would refuse to see this? & Nbsp; But here's the thing: if you look through the prism of science, we will see that & nbsp; there can be no such explosions.
- On Earth – yes, it's another matter: Earth's gravity works here, there is air with very flammable oxygen, there is atmospheric pressure. & nbsp; That is why, during the explosion, the fire scatters, and then as if compressed back.
There is none of this in space, so the explosion will look like a ball, which is constantly expanding. And the spectacle will not impress – after all, there is practically no oxygen in space, which means that there is nothing to burn.
Black holes suck in everything
In films, black holes are often shown as dark holes with a vortex that sucks in everything around. & nbsp; And of course, you can't get away from it. & nbsp ; In fact, everything is not so: a black hole is & nbsp; the same object in space as, say, a planet or a star.
- Its peculiarity is that the force of gravity there is directly proportional to the mass. Simply put, a black hole is not capable of attracting anything more than its size allows.
If you replace the Sun with a black hole of a similar size, the Earth, of course, will die – it will freeze. But a black hole won't swallow it.
Why is the hole black? Because photons (sunlight) are not reflected from it – again, due to the significant force of gravity.
