Can Macroscopic Objects Tunnel Through Walls According to Quantum Mechanics?

[Suyash Singh]

ok i read about that quantum mechanics article about how macroscopic objects have a extremely low probability of passing through a wall.Now i very clearly remember that 5-6 years back i have noticed my smiley sponge ball going into a place it cannot go to.Do you think it may have gone through the wall ?

No, I absolutely do not. The fact that something is mathematically possible does not mean it will happen. You misunderstand the concept, in this context, of "extremely low".

Extremely low as in Michael Jackson coming back from the dead and giving you the winning Powerball numbers for the next 10 drawings would be more likely.

As you can tell, the answer is no :)
