How are gravitational and electromagnetic force alike?

Answer 1

they're both energy fields

Answer 2

We don't know yet. That is the subject of some serious study, which will hopefully turn out some useful results in unifying and reconciling our understanding of how the four main forces in the universe interact. So far, we can relate the weak and strong forces and electromagnetism, but not gravity.

Answer 3

No. Gravity and EMR (electromagnetic radiation) are two of the four fundamental interactions of nature, nuclear strong force and nuclear weak force being the other two.

The electromagnetic spectrum consists of radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

The basic "unit" of EMR is the photon.

We know that gravity can bend light -- that's a given. However gravity can also influence all forms of EMR, not just visible light. The only way that this can happen is if photons have mass. If photons have mass then EMR has mass, therefore EMR must exert a gravitational force -- however minute. In other words, light is heavy!

That being the case, how can it possibly be a form of EMR? How can it be separate from all other forms of EMR (just as radio waves are separate from gamma rays) and yet still be present in all other forms of EMR?

Look at it another way. Gravity has no mass in and off itself. If it did, gravity would have gravity, and THAT gravity would have gravity, and so on. Quantum mechanics is weird enough without that kind of nonsense!

Since gravity has no mass and photons do have mass, it follows that gravity cannot have photons. And without photons, gravity cannot possibly be a form of EMR, in any way, shape or form.

QED

Answer 4

electromagnetic waves are from the spectrum

Answer 5

they're both energy fields

Answer 6

Both attract and both act between matter.

Answer 7

No.
