Can anything block gravity?

<font color="yellow">I am not aware of anything that blocks gravity other than time due to an apparent speed limit, if the theory of relativity is correct on this. <br /><br />Like, we can block electromagnetic radiation. We can block heat.</font><br /><br />Because matter emits and absorbs electromagnetic radiation.<br /><br />Electron is wave-like and particle-like, but more particle-like and less wave-like than photons are. The electron is photon-like. The proton is less photon-like than electrons are. It has the same amount of energy as photon with a frequency of 2.26873209 × 10^23 hertz<br /><br />http://www.google.com/search?q=mass+of+a+proton+%2A+speed+of+light+squared+divided+by+planck%27s+constant<br /><br />Photons with this high of a frequency are very, very sharp. They act like particles.

Kmar, <br /><br />Is this through-out the spectrum? I never really thought of it that way before. That's pretty cool. But looking at the spectrum it makes sense. AM is very wave like having really no particle properties and Gamma being very particle like. Are these particle like properties caused from the waves being so tight together?<br /><br />A better question is since Gamma Rays would be very particle like are there any mass containing particles that have attributes like gamma?
