No scientist seriously doubts the heliocentric theory, indeed evidence of it is available to anyone with a decent phone or very modest telescope and a few clear nights to observe...

Could a wormhole be caused in space by somehow placing planets too closely together thus wearing out and eventually tearing the space between planets?
The gravity between two planets is way too weak. The vicinity of a strongly gravitating object that produces a great deal of space-time curvature, such as a black hole, is...
