Can we travel back in time?

Proving the impossible

Is it possible to travel faster than light? The answer is a resounding ‘NO’. Another team of scientists has re-tested the speed of light hypothesis using the same laboratory and same set of instruments and disproved last November’s results.

When you want to break new ground, especially if that new ground involves rejecting a theory that has not only been tested, but has been successfully applied in the real world, it is advisable to test, re-test, and re-test the robustness of your experiment’s setup and your results until you are absolutely certain.

This is what CERN seems to have failed to do! They appear to have been in a hurry for fame and glory. But that haste might have misfired and come at a cost. In future, every result they release, could be met with sceptism, and be subjected to independent rigorous re-testing.

As the saying goes, if something looks to ‘good’ to be true, then it isn’t true. What many of us call common sense, didn’t seem to be common at all. What we call logic, didn’t appear to matter.

Surely, how can you receive a text message which hasn’t been sent? How can you live before you are born? Do you need to be a neutrinos scientist to know that this hypothesis doesn’t make sense in the real world we live in?

Summary

Einstein’s theory suggests that light travels at the fastest speed in the universe.

CERN has undertaken 2 experiments and got results which suggest the existence of particles that travel faster than light.

Implications – it is possible to travel back in time:

  • Someone can receive your text message before you send it!
  • Worse (better), if the particles are much faster, you could receive a reply to a text message which you are about to send.

Brief

Albert Einstein’s 1905 theory of relativity states that Energy “E” is equal to Mass “M” times the Speed of Light “C” squared – E = MC2.

Everything that exists is either energy or mass – there is no other option.

Einstein’s theory of relativity suggests that the speed of light in a vacuum, approximately 186,282 miles per second, is the ultimate universal speed limit. Nothing in the universe can travel faster.

The speed of light ( which is the speed of photons) is the fundamental speed at which time passes. So, nothing can travel faster than time.

Einstein’s theory has been widely applied. Global positioning systems (the famous Sat Navs) which find addresses benefit from a practical application of the theory of relativity — the Global Positioning System’s satellites are programmed to account for the effects of relativity.

The theory also helps explain nuclear power, or how the Sun and other stars produce energy.

Modern physics is built on the pillars of relativity and quantum mechanics. The latter explains the physics of the microscopic world. The speed of light shows up everywhere: from estimates of the size and age of the universe to the radius of black holes to the power generated by nuclear reactors. Numerous experiments have been tested relativity and quantum mechanics and found no discrepancies – until now.

The European Organization for Nuclear Research (Organisation Européenne pour la Recherche Nucléaire), known as CERN has undertaken 2 experiments and got results which suggests the existence of particles that travel faster than light.

CERN scientists used a 1300-ton particle detector to measure particles travelling faster than the speed of light.

The experiment timed about 16,000 neutrinos (tiny, ghostly particles which seldom interact with other matter) launched from CERNfacilities in Geneva, travelling through Earth and arriving 2.43 milliseconds later at the subterranean facilities of Italy’s Gran Sasso National Laboratory.

The neutrinos seemed to be reaching the detector 60 nanoseconds (a nanosecond is one-billionth of a second) faster than light.

That may be a minute discrepancy, but it should not occur if Einstein’s theory of relativity is correct.

The CERN team has scrutinized its results and hasn’t been able to find any obvious errors.

If confirmed, this discovery could invalidate Albert Einstein’s 1905 theory of special relativity and revolutionize physics.

One theory being put forward is that although it is not possible for anything other than light to travel at the speed of light, the neutrinos could have travelled through higher dimensions and taken a “short cut” to get to the detectors – after all, the neutrinos were not tracked along their path to the detectors, but were only fired and then detected at the end.

If it turns out that the CERN experiment is correct, all sorts of strange things could happen if the speed of light can be exceeded.

One immediate fact that comes to light is that it would be possible to travel back in time.

  • For instance, you could receive a text message before it is sent to you.
  • Alternatively, if they find particles that are even much faster, you could receive a reply to a text message which you are about to send.

    I almost never leave responses, however I browsed a bunch of remarks
    on Can we travel back in time? | Bedside Readings. I do have some questions
    for you if it’s okay. Could it be only me or does it appear like some of these comments come across like they are left by brain dead folks? 😛 And, if you are posting at additional social sites, I’d like to keep up with you.
    Would you list of the complete urls of all your public pages
    like your Facebook page, twitter feed, or linkedin profile?
