What happens if two objects collide going the speed of light?

The two objects must be photons, Only massless objects travel at that speed, But they can't actually collide, they interact. If the energy is great enough matter can be formed. a particle and an anti-particle.

See the article below :

It doesn't happen. Nothing with mass travels at the speed of light. You need to get very deep into the study of physics to begin to understand how massless particles interact.

you are able to study babies of the Lens by potential of E.E. (rfile) Smith, wherein the planet Ploor and its solar are smashed by potential of two planets having velocities of fifteen cases the cost of sunshine. Whee! (that's a chain: start up with Triplanetary) Returning to certainty, the formulae have been nicely examined in particle accelerators to interior of a fragment of c, like one thousandth of a p.c.. there is each and every expectation which you are able to't have debris that have a non-0 relax mass (with comprehend to you) speeded as much as c (with comprehend to you), yet, you are able to in theory, pile further and extra power into the debris so as that their velocities get closer and closer to c and their measured mass will strengthen into further and extra, and their collision would be further and extra lively. the wonderful cosmic ray debris detected handle an power of Joules, which for a single atom is important! Like, the flexibility of dropping a e book a foot in one atom's velocity. All this power released in a quantity the dimensions of an atomic nucleus is the point of the super atom smashers. The power density is amazingly super certainly in one in each and every of those small quantity. lots lots extra suitable than while 2 bullets meet head on in assessment. That in basic terms melts and shreds the bullets, it does not worry the atomic nuclei in any respect... with connection with immovable gadgets and unstoppable forces, you are able to in basic terms have at maximum one or the different because of the fact the defining characteristic of each and every denies the defining characteristic of the different.

'Objects' is a little vague, but if they do collide they might just break down into pure energy. Matter is a manifestation of energy (E=MC2). In the end, nothing will exist, besides a vacuum.
