I read somewhere that Einstein's theory of relativity proves that all space, time and matter came into existence at the Big Bang, and that when the Big Bang happened, it happened in a singularity where the laws of physics did not apply.

Could I get a non-technical but still scientific explanation of how relativity proves space, time, and matter came into existence at the Big Bang? and I don't want to hear about "imaginary time," thanks

I used to think I was kind when I would trap spiders in my house and let them go outside. Then I was told that the spider will die outside because spiders that take refuge inside need more warmth than ouside spiders.
That being said, how did these spiders live during the winter before human settlements? Have they migrated with humans from warmer climates or did they evolve to live this way?

On earth, two parts of a space probe weigh 14000 N and 5100 N. These parts are separated by a center-to-center distance of 13 m and may be treated as uniform spherical objects. Find the magnitude of the gravitational force that each part exerts on the other out in space, far from any other objects.

I know that tire pressure increases on a hot day because rise in temperature is related to rise in temp, but can you explain the following phenomenon? Please use charles's, avogado's, boyle's or the ideal gas law to illuminate

2. Weather ballon expansion as it ascends.
3. The noise of a lightbult going out.
